UI Functions

All functions that help you construct custom GUIs. They deal mainly with miniconsole/label/gauge creation and manipulation as well as displaying or formatting information on the screen.

addCommandLineMenuEvent

addCommandLineMenuEvent([window,] label, eventName)

Adds item to right click menu associated with command line.

Available in Mudlet4.14+

See also: removeCommandLineMenuEvent()

Parameters

window:

Window that command line belongs to. Optional, will default to "main" (main window console)

label:

Label of item

eventName:

Event name that will be fired when clicked.

Returns

Returns true if the mouse event was added successfully.

Example

addCommandLineMenuEvent("My very own special paste from clipboard", "pasteFromClipboardWithoutLineBreaks" )
registerAnonymousEventHandler("pasteFromClipboardWithoutLineBreaks", function()
  local text = string.gsub(getClipboardText(), "[\r|\n]", "")
  appendCmdLine(text)
end)

addMouseEvent

addMouseEvent(uniqueName, eventName, [displayName, tooltipText])

Registers a new context menu option when right-clicked on a console window. Will return true if the event was added successfully, otherwise nil+message will be returned. If the displayName isn't set, uniqueName will be used for the menu label. eventName should be a Mudlet event that will handle the click data that includes event, unique name, window name, selection upper left column and row and selection bottom right column and row in that order. This is intended to be used with available cursor functions for any selection or processing needs.

Available in Mudlet4.13+

See also: getMouseEvents(), moveCursor()

Parameters

uniqueName:

A unique identifier for the mouse event.

eventName:

Name of the Mudlet event that will handle the data.

displayName:

(optional) Label text for the mouse context menu. If not set, the label defaults to uniqueName.

tooltipText:

(optional) Tooltip text when mouse is hovered on the option. If not set, no tooltip will be visible.

Returns

Returns true if the mouse event was added successfully.

Example

-- An example showing implementing a hecho-friendly copy option:

addMouseEvent("hecho copy", "onMouseCopyExample")

function rgbToHex(r,g,b)
    local rgb = (r * 0x10000) + (g * 0x100) + b
    return string.format("#%x", rgb)
end

function onMouseCopyExample(event, menu, window, startCol, startRow, endCol, endRow)
  -- Check whether there's an actual selection
  if startCol == endCol and startRow == endRow then return end
  local parsed = ""
  local lastColor = nil
  -- Loop through each symbol within the range
  for l = startRow, endRow do
    local cStart = l == startRow and startCol or 0
    moveCursor(window, cStart, l)
    local cEnd = l == endRow and endCol or #getCurrentLine() - 1
    for c = cStart, cEnd do
      selectSection(window, c, 1)
      local symbol = getSelection(window) or ""
      -- Convert the foreground color to a hex format, suitable for hecho
      local color = rgbToHex(getFgColor(window))
      -- Don't repeat the color if previous one was the same
      if color == lastColor then
        parsed = parsed .. symbol
      else
        lastColor = color
        parsed = parsed .. color .. symbol
      end
    end
    if l ~= endRow then parsed = parsed .. "\n" end
  end
  setClipboardText(parsed)
end

registerAnonymousEventHandler("onMouseCopyExample", "onMouseCopyExample")

ansi2decho

ansi2decho(text, default_colour): Converts ANSI colour sequences in text to colour tags that can be processed by the decho() function.; See also: decho()

Available in Mudlet3.0+

Note: ANSI bold is available since Mudlet 3.7.1+.

Note: underline, italics, overline, and strikethrough supported since Mudlet 4.15+

Parameters

text:

String that contains ANSI colour sequences that should be replaced.

default_colour:

Optional - ANSI default colour code (used when handling orphan bold tags).

Return values

string text:

The decho-valid converted text.

string colour:

The ANSI code for the last used colour in the substitution (useful if you want to colour subsequent lines according to this colour).

Example

local replaced = ansi2decho('\27[0;1;36;40mYou say in a baritone voice, "Test."\27[0;37;40m')
-- 'replaced' should now contain <r><0,255,255:0,0,0>You say in a baritone voice, "Test."<r><192,192,192:0,0,0>
decho(replaced)

Or show a complete colourful squirrel! It's a lotta code to do all the colours, so click the Expand button on the right to show it:

ansi2string

ansi2string(text): Strips ANSI colour sequences from a string (text); See also: ansi2decho()

Available in Mudlet4.10+

Parameters

text:

String that contains ANSI colour sequences that should be removed.

Return values

string text:

The plain text without ANSI colour sequences.

Example

local replaced = ansi2string('\27[0;1;36;40mYou say in a baritone voice, "Test."\27[0;37;40m')
-- 'replaced' should now contain You say in a baritone voice, "Test."
print(replaced)

appendBuffer

appendBuffer(name): Pastes the previously copied rich text (including text formats like color etc.) into user window name.; See also: selectCurrentLine(), copy(), paste()

Parameters

name:

The name of the user window to paste into. Passed as a string.

Example

--selects and copies an entire line to user window named "Chat"
selectCurrentLine()
copy()
appendBuffer("Chat")

bg

bg([window, ]colorName): Changes the background color of the text. Useful for highlighting text.; See Also: fg(), setBgColor()

Parameters

window:

The miniconsole to operate on - optional. If you'd like it to work on the main window, don't specify anything, or use main (since Mudlet 3.0).

colorName:

The name of the color to set the background to.

Example

--This would change the background color of the text on the current line to magenta
selectCurrentLine()
bg("magenta")

-- or echo text with a green background to a miniconsole
bg("my window", "green")
echo("my window", "some green text\n")

calcFontSize

calcFontSize(window_or_fontsize, [fontname]): Returns the average height and width of characters in a particular window, or a font name and size combination. Helpful if you want to size a miniconsole to specific dimensions.; Returns two numbers, width/height; See also: setMiniConsoleFontSize(), getMainWindowSize()

Parameters

window_or_fontsize:

The miniconsole or font size you are wanting to calculate pixel sizes for.

fontname:

Specific font name (along with the size as the first argument) to calculate for.

Note: Window as an argument is available in Mudlet 3.10+, and font name in Mudlet 4.1+.

Example

--this snippet will calculate how wide and tall a miniconsole designed to hold 4 lines of text 20 characters wide
--would need to be at 9 point font, and then changes miniconsole Chat to be that size
local width,height = calcFontSize(9)
width = width * 20
height = height * 4
resizeWindow("Chat", width, height)

cecho

cecho([window], text): Echoes text that can be easily formatted with colour and the below tags. You can also include unicode art in it - try some examples from 1lineart.

Formatting

<b>  - bold
</b> - bold off
<i>  - italics
</i> - italics off
<u>  - underline
</u> - underline off
<o>  - overline
</o> - overline off
<s>  - strikethrough
</s> - strikethrough off

See also: decho(), hecho(), creplaceLine()

Note: Support for labels added in Mudlet 4.15; however, it does not turn a label into a miniconsole and every time you cecho it will erase any previous echo sent to the label.

Parameters

window:

Optional - the window name to echo to - can either be none or "main" for the main window, or a miniconsole, userwindow, or label name.

text:

The text to display, with color names inside angle brackets <>, ie <red>. If you'd like to use a background color, put it after a colon : - <:red>. You can use the <reset> tag to reset to the default color. You can select any from this list:

Example

cecho("Hi! This text is <red>red, <blue>blue, <green> and green.")

cecho("<:green>Green background on normal foreground. Here we add an <ivory>ivory foreground.")

cecho("<blue:yellow>Blue on yellow text!")

cecho("\n<red>Red text with <i>italics</i>, <u>underline</u>, <s>strikethrough</s>, <o>overline</o>, and <b>bold</b>.")

cecho("\n<green><o><u>Green text with over and underline at the same time.</o></u>")

-- \n adds a new line
cecho("<red>one line\n<green>another line\n<blue>last line")

cecho("myinfo", "<green>All of this text is green in the myinfo miniconsole.")

cecho("<green>(╯°□°）<dark_green>╯︵ ┻━┻")

cecho("°º¤ø,¸¸,ø¤º°`°º¤ø,¸,ø¤°º¤ø,¸¸,ø¤º°`°º¤ø,¸")

cecho([[

]])

cechoLink

cechoLink([windowName], text, command, hint, true): Echos a piece of text as a clickable link, at the end of the current selected line - similar to cecho(). This version allows you to use colours within your link text.

See also: echoLink(), dechoLink(), hechoLink()

Parameters

windowName:

optional parameter, allows selection between sending the link to a miniconsole or the main window.

text:

text to display in the echo. Same as a normal cecho().

command:

Lua code to do when the link is clicked, as text or a function (since Mudlet 4.11).

hint:

text for the tooltip to be displayed when the mouse is over the link.

true:

requires argument for the colouring to work.

Example

-- echo a link named 'press me!' that'll send the 'hi' command to the game
cechoLink("<red>press <brown:white>me!", function() send("hi") end, "This is a tooltip", true)

-- alternatively, put command as text (in [[ and ]] to use quotation marks inside)
cechoLink("<red>press <brown:white>me!", [[send("hi")]], "This is a tooltip", true)

cecho2ansi

ansiFormattedString = cecho2ansi(text)

Converts cecho formatted text to ansi formatted text. Used by cfeedTriggers, but useful if you want ansi formatted text for any other reason.

See also: cecho(), cfeedTriggers()

Available in Mudlet4.15+

Note: This function uses the ansi short colors (0-15) for color names which have base 16 ansi equivalents, such as 'red', 'blue', "lightBlue", "cyan", etc rather than the values defined in the color_table. If there is no base ansi equivalent then it will use the rgb values from the color_table for the color.

Parameters

text:

The cecho formatted text for conversion

Returns

String converted to ansi formatting

Example

-- replicates the functionality of cfeedTriggers() for a single line.
-- you would most likely just use cfeedTriggers, but it makes for a tidy example.
feedTriggers(cecho2ansi("\n<red>This is red.<reset> <i>italic</i>, <b>bold</b>, <s>strikethrough</s>, <u>underline</u>\n"))

cechoPopup

cechoPopup([windowName], text, {commands}, {hints}, [useCurrentFormatElseDefault]): Creates text with a left-clickable link, and a right-click menu for more options at the end of the current line, like cecho(). The added text, upon being left-clicked, will do the first command in the list. Upon being right-clicked, it'll display a menu with all possible commands. The menu will be populated with hints, one for each line.

Available in Mudlet4.1+

Parameters

windowName:

(optional) name of the window to echo to. Use either main or omit for the main window, or the miniconsoles name otherwise.

text:

the text to display

{commands}:

a table of lua code to do, in text strings or as functions (since Mudlet 4.11), i.e. {[[send("hello")]], function() echo("hi!") end}

{hints}:

a table of strings which will be shown on the popup and right-click menu. ie, {"send the hi command", "echo hi to yourself"}

useCurrentFormatElseDefault:

(optional) a boolean value for using either the current formatting options (colour, underline, italic) or the link default (blue underline).

Example

-- Create some text as a clickable with a popup menu:
cechoPopup("<red>activities<reset> to do", {function() send "sleep" end, function() send "sit" end, function() send "stand" end}, {"sleep", "sit", "stand"}, true)

-- alternatively, put command as text (in [[ and ]] to use quotation marks inside)
cechoPopup("<red>activities<reset> to do", {[[send "sleep"]], [[send "sit"]], [[send "stand"]]}, {"sleep", "sit", "stand"}, true)

cinsertLink

cinsertLink([windowName], text, command, hint, true): Echos a piece of text as a clickable link, at the end of the current cursor position - similar to cinsertText(). This version allows you to use colours within your link text.

cinsertPopup

cinsertPopup([windowName], text, {commands}, {hints}, [useCurrentFormatElseDefault]): Creates text with a left-clickable link, and a right-click menu for more options at the end of the current cursor position, like cinsertText(). The added text, upon being left-clicked, will do the first command in the list. Upon being right-clicked, it'll display a menu with all possible commands. The menu will be populated with hints, one for each line.

Available in Mudlet4.1+

Parameters

windowName:

(optional) name of the window to echo to. Use either main or omit for the main window, or the miniconsoles name otherwise.

text:

the text to display

a table of strings which will be shown on the popup and right-click menu. ie, {"send the hi command", "echo hi to yourself"}

useCurrentFormatElseDefault:

(optional) a boolean value for using either the current formatting options (colour, underline, italic) or the link default (blue underline).

Example

-- Create some text as a clickable with a popup menu:
cinsertPopup("<red>activities<reset> to do", {function() send "sleep" end, function() send "sit" end, function() send "stand" end}, {"sleep", "sit", "stand"}, true)

-- Create some text as a clickable with a popup menu:
cinsertPopup("<red>activities<reset> to do", {[[send "sleep"]], [[send "sit"]], [[send "stand"]]}, {"sleep", "sit", "stand"}, true)

cinsertText

cinsertText([window], text): inserts text at the current cursor position, with the possibility for color tags.; See Also: cecho(), creplaceLine()

Parameters

window:

Optional - the window name to echo to - can either be none or "main" for the main window, or the miniconsoles name.

text:

The text to display, with color names inside angle brackets <>, ie <red>. If you'd like to use a background color, put it after a double colon : - <:red>. You can use the <reset> tag to reset to the default color. You can select any from this list:

Example

cinsertText("Hi! This text is <red>red, <blue>blue, <green> and green.")

cinsertText("<:green>Green background on normal foreground. Here we add an <ivory>ivory foreground.")

cinsertText("<blue:yellow>Blue on yellow text!")

cinsertText("myinfo", "<green>All of this text is green in the myinfo miniconsole.")

clearUserWindow

clearUserWindow([name]): This is (now) identical to clearWindow().

clearWindow

clearWindow([windowName]): Clears the label, mini console, or user window with the name given as argument (removes all text from it). If you don't give it a name, it will clear the main window.

Parameters

windowName:

(optional) The name of the label, mini console, or user window to clear. Passed as a string.

Example

--This would clear a label, user window, or miniconsole with the name "Chat"
clearWindow("Chat")

-- this can clear your whole main window
clearWindow()

closestColor

closestColor(colorOrR[,G,B])

Returns the closest color from the color_table to the one provided for use in cecho and associated functions.

Available in Mudlet4.13+

Parameters

colorOrR:

Either the string representation of a color from decho or hecho (IE "#ff0077" or "<255,0,128>"), a table of color values (IE {255,0,18}), or the Red component of RGB when followed by two next optional parameters

G:

(optional) green component of RGB coordinates. Only needed if first parameter sent as the Red component only

B:

(optional) blue component of RGB coordinates. Only needed if first parameter sent as the Red component only

Returns

The closest color name from the color_table to the one supplied on success
nil + error if it cannot parse the parameters into a color.

Example

local colorName = closestColor(255, 0, 0) -- "ansi_light_red"
local colorName = closestColor({127, 255, 127}) -- "ansi_120"
local colorName = closestColor("<127, 127, 127>") -- "ansi_008"
local colorName = closestColor("#a020e6") -- "purple"
local colorName = closestColor("blue") -- "blue" (you wouldn't necessarily do this on purpose, but during automated color conversions this might occur)

copy

copy([windowName]): Copies the current selection to the lua virtual clipboard. This function operates on rich text, i. e. the selected text including all its format codes like colors, fonts etc. in the lua virtual clipboard until it gets overwritten by another copy operation.; See also: selectString(), selectCurrentLine(), paste(), appendBuffer(), replace(), createMiniConsole(), openUserWindow()

Parameters

windowName (optional):

the window from which to copy text - use the main console if not specified.

Example

-- This script copies the current line on the main screen to a window (miniconsole or userwindow) called 'chat' and gags the output on the main screen.

stringToCopy (optional):

the string to copy. Defaults to copying the entire line.

instanceToCopy (optional):

the instance of the string to copy. Defaults to 1.

Example

-- This copies the current line on the main console and dechos it to a miniconsole named "test"
decho("test", copy2decho())

-- This when put into a trigger would copy matches[2] with color information and decho it to a Geyser miniconsole stored as the variable enemylist
enemylist:decho(copy2decho(matches[2]))

copy2html

copy2html([window], [stringToCopy], [instanceToCopy]): Copies a string from the current line of window, including color information in html format for echoing to a label.

the instance of the string to copy. Defaults to 1

Example

-- This copies the current line on the main console and echos it to a label named "TestLabel"
echo("TestLabel", copy2html())

-- This when put into a trigger would copy matches[2] with color information and echo it to a Geyser label stored as the variable enemylist
enemylist:echo(copy2html(matches[2]))

createBuffer

createBuffer(name): Creates a named buffer for formatted text, much like a miniconsole, but the buffer is not intended to be shown on the screen - use it for formatting text or storing formatted text.

Parameters

name:

The name of the buffer to create.

Example

--This creates a named buffer called "scratchpad"
createBuffer("scratchpad")

createCommandLine

createCommandLine([name of userwindow], name, x, y, width, height): Creates a new command line inside the main window of Mudlet. If only a command line inside a miniConsole/UserWindow is needed see enableCommandLine().; You can use appendCmdLine() / getCmdLine() and other command line functions to customize the input.

Returns true or false.

Parameters

name of userwindow:

Name of userwindow the command line is created in. Optional, defaults to the main window if not provided.

name:

The name of the command line. Must be unique. Passed as a string.

x, y, width, height

Parameters to set the command line size and location - it is also possible to set them by using moveWindow() and resizeWindow(), as createCommandLine() will only set them once.

-- 20 lines high, at coordinates 300x,400y
createConsole("myConsoleWindow", 8, 80, 20, 200, 400)

Note:

(For Mudlet Makers) This function is implemented outside the application's core via the GUIUtils.lua file of the Mudlet supporting Lua code using createMiniConsole() and other functions to position and size the mini-console and configure the font.

createGauge

createGauge([name of userwindow], name, width, height, Xpos, Ypos, gaugeText, r, g, b, orientation)
createGauge([name of userwindow], name, width, height, Xpos, Ypos, gaugeText, colorName, orientation): Creates a gauge that you can use to express completion with. For example, you can use this as your healthbar or xpbar.; See also: moveGauge(), setGauge(), setGaugeText(), setGaugeStyleSheet()

Note: userwindow argument only available in 4.6.1+

Example

-- This would make a gauge at that's 300px width, 20px in height, located at Xpos and Ypos and is green.
-- The second example is using the same names you'd use for something like [[fg]]() or [[bg]]().
createGauge("healthBar", 300, 20, 30, 300, nil, 0, 255, 0)
createGauge("healthBar", 300, 20, 30, 300, nil, "green")


-- If you wish to have some text on your label, you'll change the nil part and make it look like this:
createGauge("healthBar", 300, 20, 30, 300, "Now with some text", 0, 255, 0)
-- or
createGauge("healthBar", 300, 20, 30, 300, "Now with some text", "green")

Note:

If you want to put text on the back of the gauge when it's low, use an echo with the <gauge name>_back.

echo("healthBar_back", "This is a test of putting text on the back of the gauge!")

createLabel

createLabel([name of userwindow], name, Xpos, Ypos, width, height, fillBackground, [enableClickthrough]): Creates a highly manipulable overlay which can take some css and html code for text formatting. Labels are clickable, and as such can be used as a sort of button. Labels are meant for small variable or prompt displays, messages, images, and the like. You should not use them for larger text displays or things which will be updated rapidly and in high volume, as they are much slower than miniconsoles.; Returns true or false.; See also: hideWindow(), showWindow(), resizeWindow(), setLabelClickCallback(), setTextFormat(), getTextFormat(), moveWindow(), setBackgroundColor(), getMainWindowSize(), calcFontSize(), deleteLabel()

Parameters

name of userwindow: Name of userwindow label is created in. Optional, defaults to the main window if not provided.

Note: userwindow argument only available in 4.6.1+

Example

-- a label situated at x=300 y=400 with dimensions 100x200
createLabel("a very basic label",300,400,100,200,1)

-- this example creates a transparent overlay message box to show a big warning message "You are under attack!" in the middle
-- of the screen. Because the background color has a transparency level of 150 (0-255, with 0 being completely transparent
-- and 255 opaque) the background text can still be read through.
local width, height = getMainWindowSize()
createLabel("messageBox",(width/2)-300,(height/2)-100,250,150,1)
resizeWindow("messageBox",500,70)
moveWindow("messageBox", (width/2)-300,(height/2)-100 )
setBackgroundColor("messageBox", 255, 204, 0, 200)
echo("messageBox", [[<p style="font-size:35px"><b><center><font color="red">You are under attack!</font></center></b></p>]])

-- you can also make it react to clicks!
mynamespace = {
  messageBoxClicked = function()
    echo("hey you've clicked the box!\n")
  end
}

setLabelClickCallback("messageBox", "mynamespace.messageBoxClicked")


-- uncomment code below to make it also hide after a short while
-- tempTimer(2.3, [[hideWindow("messageBox")]] ) -- close the warning message box after 2.3 seconds

createMiniConsole

createMiniConsole([name of userwindow], name, x, y, width, height): Opens a miniconsole window inside the main window of Mudlet. This is the ideal fast colored text display for everything that requires a bit more text, such as status screens, chat windows, etc. Unlike labels, you cannot have transparency in them.; You can use clearWindow() / moveCursor() and other functions for this window for custom printing as well as copy & paste functions for colored text copies from the main window. setWindowWrap() will allow you to set word wrapping, and move the main window to make room for miniconsole windows on your screen (if you want to do this as you can also layer mini console and label windows) see setBorderSizes(), setBorderColor() functions.

Returns true or false.

Parameters

name of userwindow: (available in Mudlet 4.6.1+)

(Optional) name of userwindow the miniconsole is created in. Defaults to the main window if not provided.

name:

The name of the miniconsole. Must be unique. Passed as a string.

x, y, width, height

Parameters to set set the window size and location - in Mudlet version 2.1 and below it's best to set them via moveWindow() and resizeWindow(), as createMiniConsole() will only set them once. Starting with Mudlet version 3.0, however, that is fine and calling createMiniConsole() will re-position your miniconsole appropriately.

createScrollBox

createScrollBox([name of parent window], name, x, y, width, height)

creates a graphical elements able to hold other graphical elements such as labels, miniconsoles, command lines etc. in it.

If the added elements don't fit into the ScrollBox scrollbars appear and allow scrolling.

Returns true or false.

Available in Mudlet4.15+

Parameters

name of parent window:

(Optional) name of the parent window the scrollBox is created in. Defaults to the main window if not provided.

name:

The name of the scrollBox. Must be unique. Passed as a string.

x, y, width, height

Parameters to set set the window size and location

Example

-- create a ScrollBox with the name sBox
createScrollBox("SBox",0,0,300,200)

-- create 3 Labels and put them into the ScrollBox
createLabel("SBox","SBoxLabel",0,0,200,200,1)
createLabel("SBox","SBoxLabel2",200,0,200,200,1)
createLabel("SBox","SBoxLabel3",400,0,200,200,1)

-- put some text on the labels
echo("SBoxLabel","Label")
echo("SBoxLabel2","Label2")
echo("SBoxLabel3","Label3")

-- change the colours of the labels to make it easier to distinguish them
setBackgroundColor("SBoxLabel",255,0,0)
setBackgroundColor("SBoxLabel2",0,255,0)
setBackgroundColor("SBoxLabel3",0,0,255)

creplace

creplace([window, ]text): Replaces the output line from the game with a colour-tagged string.

creplaceLine

creplaceLine ([window], text): Replaces the output line from the game with a colour-tagged string.

decho

decho ([name of console,] text): Color changes can be made using the format <FR,FG,FB:BR,BG,BB,[BA]> where each field is a number from 0 to 255. The background portion can be omitted using <FR,FG,FB> or the foreground portion can be omitted using <:BR,BG,BB,[BA]>. Arguments 2 and 3 set the default fore and background colors for the string using the same format as is used within the string, sans angle brackets, e.g. decho("<50,50,0:0,255,0>test").; You can also include the below tags.

Formatting

<b>  - bold
</b> - bold off
<i>  - italics
</i> - italics off
<u>  - underline
</u> - underline off
<o>  - overline
</o> - overline off
<s>  - strikethrough
</s> - strikethrough off
<r> - reset formatting

Note: Support for labels added in Mudlet 4.15; however, it does not turn a label into a miniconsole and every time you decho it will erase any previous echo sent to the label.

See also: cecho(), hecho(), copy2decho()

Parameters

name of console

(Optional) Name of the console to echo to. If no name is given, this will defaults to the main window.

text:

The text that you’d like to echo with embedded color tags. Tags take the RGB values only, see below for an explanation.

Note: Optional background transparancy parameter (BA) available in Mudlet 4.10+

Example

decho("<50,50,0:0,255,0>test")

decho("miniconsolename", "<50,50,0:0,255,0>test")

decho("\n<255,0,0>Red text with <i>italics</i>, <u>underline</u>, <s>strikethrough</s>, and <b>bold</b> formatting.")

decho("<\n<0,128,0><o><u>Green text with both over and underlines.</u></o>")

decho2ansi

ansiFormattedString = decho2ansi(text)

Converts decho formatted text to ansi formatted text. Used by dfeedTriggers, but useful if you want ansi formatted text for any other reason.

See also: decho(), dfeedTriggers()

Available in Mudlet4.10++

Note: non-color formatting added in Mudlet 4.15+

Parameters

text:

The decho formatted text for conversion

Returns

String converted to ansi formatting

Example

-- replicates the functionality of dfeedTriggers() for a single line.
-- you would most likely just use dfeedTriggers, but it makes for a tidy example.
feedTriggers(decho2ansi("\n<128,0,0>This is red.<r> <i>italic</i>, <b>bold</b>, <s>strikethrough</s>, <u>underline</u>\n"))

dechoLink

dechoLink([windowName], text, command, hint, true): Echos a piece of text as a clickable link, at the end of the current selected line - similar to decho(). This version allows you to use colours within your link text.

Parameters

windowName:

(optional) allows selection between sending the link to a miniconsole or the "main" window.

text:

text to display in the echo. Same as a normal decho().

command:

Lua code to do when the link is clicked, as text or a function (since Mudlet 4.11).

hint:

text for the tooltip to be displayed when the mouse is over the link.

true:

requires argument for the colouring to work.

Example

-- echo a link named 'press me!' that'll send the 'hi' command to the game
dechoLink("<50,50,0:0,255,0>press me!", function() send("hi") end, "This is a tooltip", true)

-- alternatively, put command as text (in [[ and ]] to use quotation marks inside)
dechoLink("<50,50,0:0,255,0>press me!", [[send("hi")]], "This is a tooltip", true)

dechoPopup

dechoPopup([windowName], text, {commands}, {hints}, [useCurrentFormatElseDefault]): Creates text with a left-clickable link, and a right-click menu for more options at the end of the current line, like decho(). The added text, upon being left-clicked, will do the first command in the list. Upon being right-clicked, it'll display a menu with all possible commands. The menu will be populated with hints, one for each line.

Available in Mudlet4.1+

Parameters

windowName:

(optional) name of the window to echo to. Use either main or omit for the main window, or the miniconsoles name otherwise.

useCurrentFormatElseDefault:

(optional) a boolean value for using either the current formatting options (colour, underline, italic) or the link default (blue underline).

Example

-- Create some text as a clickable with a popup menu:
dechoPopup("<255,0,0>activities<r> to do", {function() send "sleep" end, function() send "sit" end, function() send "stand" end}, {"sleep", "sit", "stand"}, true)

-- alternatively, put command as text (in [[ and ]] to use quotation marks inside)
dechoPopup("<255,0,0>activities<r> to do", {[[send "sleep"]], [[send "sit"]], [[send "stand"]]}, {"sleep", "sit", "stand"}, true)

dinsertLink

dinsertLink([windowName], text, command, hint, true): Echos a piece of text as a clickable link, at the end of the current cursor position - similar to dinsertText(). This version allows you to use colours within your link text.

dinsertPopup

dinsertPopup([windowName], text, {commands}, {hints}, [useCurrentFormatElseDefault]): Creates text with a left-clickable link, and a right-click menu for more options at the end of the current cursor position, like dinsertText(). The added text, upon being left-clicked, will do the first command in the list. Upon being right-clicked, it'll display a menu with all possible commands. The menu will be populated with hints, one for each line.

Available in Mudlet4.1+

Parameters

windowName:

(optional) name of the window to echo to. Use either main or omit for the main window, or the miniconsoles name otherwise.

Example

-- Create some text as a clickable with a popup menu:
dinsertPopup("<255,0,0>activities<r> to do", {function() send "sleep" end, function() send "sit" end, function() send "stand" end}, {"sleep", "sit", "stand"}, true)

-- alternatively, put command as text (in [[ and ]] to use quotation marks inside)
dinsertPopup("<255,0,0>activities<r> to do", {[[send "sleep"]], [[send "sit"]], [[send "stand"]]}, {"sleep", "sit", "stand"}, true)

deleteLabel

deleteLabel(labelName)

Deletes and removes a label from the screen. Note that if you'd like to show the label again, it is much more performant to hide/show it instead.

Note that you shouldn't use the Geyser label associated with the label you delete afterwards - that doesn't make sense and Geyser right now wouldn't know that it's been deleted, either.

Parameters

labelName: name of the label to delete.

createLabel("a very basic label",300,400,100,200,1)
setBackgroundColor("a very basic label", 255, 204, 0, 200)

-- delete the label after 3 seconds
tempTimer(3, function()
  deleteLabel("a very basic label")
end)

Available in Mudlet4.5+

deleteLine

deleteLine([windowName]): Deletes the current line under the user cursor. This is a high speed gagging tool and is very good at this task, but is only meant to be use when a line should be omitted entirely in the output. If you echo() to that line it will not be shown, and lines deleted with deleteLine() are simply no longer rendered. This is purely visual - triggers will still fire on the line as expected.; See also: replace(), wrapLine()

Parameters

windowName:

(optional) name of the window to delete the line in. If no name is given, it just deletes the line it is used on.

Note: for replacing text, replace() is the proper option; doing the following: selectCurrentLine(); replace(""); cecho("new line!\n") is better.

Example

-- deletes the line - just put this command into the big script box. Keep the case the same -
-- it has to be deleteLine(), not Deleteline(), deleteline() or anything else
deleteLine()

--This example creates a temporary line trigger to test if the next line is a prompt, and if so gags it entirely.
--This can be useful for keeping a pile of prompts from forming if you're gagging chat channels in the main window
--Note: isPrompt() only works on servers which send a GA signal with their prompt.
tempLineTrigger(1, 1, [[if isPrompt() then deleteLine() end]])

-- example of deleting multiple lines:
deleteLine()                            -- delete the current line
moveCursor(0,getLineNumber()-1)         -- move the cursor back one line
deleteLine()                            -- delete the previous line now

deselect

deselect([window name]): This is used to clear the current selection (to no longer have anything selected). Should be used after changing the formatting of text, to keep from accidentally changing the text again later with another formatting call.; See also: selectString(), selectCurrentLine()

Parameters

window name:

(optional) The name of the window to stop having anything selected in. If name is not provided the main window will have its selection cleared.

Example

--This will change the background on an entire line in the main window to red, and then properly clear the selection to keep further
--changes from effecting this line as well.
selectCurrentLine()
bg("red")
deselect()

disableClickthrough

disableClickthrough(label): Disables clickthrough for a label - making it act 'normal' again and receive clicks, doubleclicks, onEnter, and onLeave events. This is the default behaviour for labels.; See also: enableClickthrough()

Parameters

label:

Name of the label to restore clickability on.

Available in Mudlet3.17+

disableCommandLine

disableCommandLine(windowName): Disables the command line for the miniConsole named windowName; See Also: enableCommandLine()

echoLink

echoLink([windowName], text, command, hint, [useCurrentFormatElseDefault]): Echos a piece of text as a clickable link, at the end of the current selected line - similar to echo().

echoUserWindow

echoUserWindow(windowName, text): This function will print text to both mini console windows, dock windows and labels. It is outdated however - echo() instead.

echoPopup

echoPopup([windowName], text, {commands}, {hints}, [useCurrentFormatElseDefault]): Creates text with a left-clickable link, and a right-click menu for more options at the end of the current line, like echo. The added text, upon being left-clicked, will do the first command in the list. Upon being right-clicked, it'll display a menu with all possible commands. The menu will be populated with hints, one for each line.

getColumnCount

getColumnCount([windowName]): Gets the maximum number of columns (characters) that a given window can display on a single row, taking into consideration factors such as window width, font size, spacing, etc.

Parameters

windowName:

Available in Mudlet3.7+

Example

print("Maximum number of columns on the main window "..getColumnCount())

getColumnNumber

getColumnNumber([windowName]): Gets the absolute column number of the current user cursor.

Parameters

windowName:

print("getColumnNumber: "..tostring(getColumnNumber("HelloWorld")))

getCurrentLine

getCurrentLine([windowName]): Returns the content of the current line under the user cursor in the buffer. The Lua variable line holds the content of getCurrentLine() before any triggers have been run on this line. When triggers change the content of the buffer, the variable line will not be adjusted and thus hold an outdated string. line = getCurrentLine() will update line to the real content of the current buffer. This is important if you want to copy the current line after it has been changed by some triggers. selectString( line,1 ) will return false and won't select anything because line no longer equals getCurrentLine(). Consequently, selectString( getCurrentLine(), 1 ) is what you need.

Parameters

windowName:

(optional) name of the window in which to select text.

Example

print("Currently selected line: "..getCurrentLine())

getFgColor

getFgColor(windowName): This function returns the rgb values of the color of the first character of the current selection on mini console (window) windowName. If windowName is omitted Mudlet will use the main screen.

Parameters

A window to operate on - either a miniconsole or the main window.

Example

selectString("troll",1)
local r,g,b = getFgColor()
if r == 255 and g == 0 and b == 0 then
  echo("HELP! troll is written in red letters, the monster is aggressive!\n")
end

handleWindowResizeEvent

handleWindowResizeEvent(): (deprecated) This function is deprecated and should not be used; it's only documented here for historical reference - use the sysWindowResizeEvent event instead.

The standard implementation of this function does nothing. However, this function gets called whenever the main window is being manually resized. You can overwrite this function in your own scripts to handle window resize events yourself and e. g. adjust the screen position and size of your mini console windows, labels or other relevant GUI elements in your scripts that depend on the size of the main Window. To override this function you can simply put a function with the same name in one of your scripts thus overwriting the original empty implementation of this.

Parameters: None

Example

function handleWindowResizeEvent()
   -- determine the size of your screen
   WindowWidth=0;
   WindowHeight=0;
   WindowWidth, WindowHeight = getMainWindowSize();

   -- move mini console "sys" to the far right side of the screen whenever the screen gets resized
   moveWindow("sys",WindowWidth-300,0)
end

hasFocus

hasFocus(): Returns true or false depending if Mudlet's main window is currently in focus (ie, the user isn't focused on another window, like a browser). If multiple profiles are loaded, this can also be used to check if a given profile is in focus.

Parameters: None

Example

if attacked and not hasFocus() then
  runaway()
else
  fight()
end

hecho

hecho([windowName], text): Echoes text that can be easily formatted with colour tags in the hexadecimal format. You can also add the below tags.

Formatting

#b or |b   - bold
#/b or |/b - bold off
#i or |i   - italics
#/i or |/i - italics off
#u or |u   - underline
#/u or |/u - underline off
#o or |o   - overline
#/o or |/o - overline off
#s or |s   - strikethrough
#/s or |/s - strikethrough off
#r or |r   - reset to default

hechoLink

hechoLink([windowName], text, command, hint, true): Echos a piece of text as a clickable link, at the end of the current selected line - similar to hecho(). This version allows you to use colours within your link text.

hechoPopup

hechoPopup([windowName], text, {commands}, {hints}, [useCurrentFormatElseDefault]): Creates text with a left-clickable link, and a right-click menu for more options at the end of the current line, like hecho(). The added text, upon being left-clicked, will do the first command in the list. Upon being right-clicked, it'll display a menu with all possible commands. The menu will be populated with hints, one for each line.

Available in Mudlet4.1+

Parameters

windowName:

(optional) name of the window to echo to. Use either main or omit for the main window, or the miniconsoles name otherwise.

text:

the text to display

{commands}:

a table of lua code to do, in text strings or as functions (since Mudlet 4.11), i.e. {[[send("hello")]], function() echo("hi!") end}

{hints}:

a table of strings which will be shown on the popup and right-click menu. ie, {"send the hi command", "echo hi to yourself"}

useCurrentFormatElseDefault:

(optional) a boolean value for using either the current formatting options (colour, underline, italic) or the link default (blue underline).

Example

-- Create some text as a clickable with a popup menu:
hechoPopup("#ff0000activities#r to do", {function() send "sleep" end, function() send "sit" end, function() send "stand" end}, {"sleep", "sit", "stand"}, true)

-- alternatively, put command as text (in [[ and ]] to use quotation marks inside)

hreplace([window, ]text): Replaces the output line from the game with a colour-tagged string.

hideToolBar

hideToolBar(name): Hides the toolbar with the given name name and makes it disappear. If all toolbars of a tool bar area (top, left, right) are hidden, the entire tool bar area disappears automatically.

Parameters

name:

name of the button group to hide

Example

hideToolBar("my offensive buttons")

hideWindow

hideWindow(name): This function hides a mini console, a user window or a label with the given name. To show it again, use showWindow().

Parameters

name

specifies the label or console you want to hide.

Example

function miniconsoleTest()
  local windowWidth, windowHeight = getMainWindowSize()

  -- create the miniconsole
  createMiniConsole("sys", windowWidth-650,0,650,300)
  setBackgroundColor("sys",255,69,0,255)
  setMiniConsoleFontSize("sys", 8)
  -- wrap lines in window "sys" at 40 characters per line - somewhere halfway, as an example
  setWindowWrap("sys", 40)

  print("created red window top-right")

  tempTimer(1, function()
    hideWindow("sys")
    print("hid red window top-right")
  end)

  tempTimer(3, function()
    showWindow("sys")
    print("showed red window top-right")
  end)
end

miniconsoleTest()

insertLink

insertLink([windowName], text, command, hint, [useCurrentLinkFormat]): Inserts a piece of text as a clickable link at the current cursor position - similar to insertText().

Parameters

windowName:

(optional) the window to insert the link in - use either "main" or omit for the main window.

text:

text to display in the window. Same as a normal echo().

command:

Lua code to do when the link is clicked, as text or a function (since Mudlet 4.11).

hint:

text for the tooltip to be displayed when the mouse is over the link.

useCurrentLinkFormat:

(optional) true or false. If true, then the link will use the current selection style (colors, underline, etc). If missing or false, it will use the default link style - blue on black underlined text.

Example

-- link with the default blue on white colors
insertLink("hey, click me!", function() echo("you clicked me!\n") end, "Click me popup")

-- alternatively, put command as text (in [[ and ]] to use quotation marks inside)
insertLink("hey, click me!", [[echo("you clicked me!\n")]], "Click me popup")

-- use current cursor colors by adding true at the end
fg("red")
insertLink("hey, click me!", function() echo("you clicked me!\n") end, "Click me popup", true)
resetFormat()

Note: The hint can contain the same sort of "rich-text" as can be used for "labels" - and if the command is set to be the empty string "" then this can be a means to show extra information for the text when the mouse is hovered over it but without a command being run should it be clicked upon, e.g.:

Screenshot showing example of fancy visual link

insertPopup

insertPopup([windowName,] text, {commands}, {hints}[, useCurrentLinkFormat]): Creates text with a left-clickable link, and a right-click menu for more options exactly where the cursor position is, similar to insertText(). The inserted text, upon being left-clicked, will do the first command in the list. Upon being right-clicked, it'll display a menu with all possible commands. The menu will be populated with hints, one for each line.

Parameters

windowName:

(optional) name of the window to echo to - use either main or omit for the main window, or the miniconsoles name otherwise.

text:

the text inserted for the popup to be applied to.

{commands}:

a table of lua code commands to do, in text strings or as functions (since Mudlet 4.11), i.e. {[[send("hello")]], function() echo("hi!") end}.

{hints}:

a table of strings which will be shown when the pointer hovers over the popup's text and on the right-click menu. ie, {"send the hi command", "echo hi to yourself"}.

useCurrentLinkFormat:

(optional) boolean value for using either the current formatting options (colour, underline, italic) or the link default (blue underline).

Example

-- Create some text as a clickable with a popup menu:
insertPopup("activities to do", {function() send "sleep" end, function() send "sit" end, function() send "stand" end}, {"sleep", "sit", "stand"})

-- alternatively, put command as text (in [[ and ]] to use quotation marks inside)
insertPopup("activities to do", {[[send "sleep"]], [[send "sit"]], [[send "stand"]]}, {"sleep", "sit", "stand"})

insertText

insertText([windowName], text): Inserts text at cursor postion in window - unlike echo(), which inserts the text at the end of the last line in the buffer (typically the one being processed by the triggers). You can use moveCursor() to move the cursor into position first.

insertHTML() also does the same thing as insertText, if you ever come across it.

ioprint

ioprint(text, some more text, ...): Prints text to the to the stdout. This is only available if you launched Mudlet from cmd.exe on Windows, from the terminal on Mac, or from the terminal on a Linux OS (launch the terminal program, type mudlet and press enter).

Similar to echo(), but does not require a "\n" at the end for a newline and can print several items given to it. It cannot print whole tables. This function works similarly to the print() you will see in guides for Lua.

This function is useful in working out potential crashing problems with Mudlet due to your scripts - as you will still see whatever it printed when Mudlet crashes.

Parameters

text:

The information you want to display.
Example

ioprint("hi!")
ioprint(1,2,3)
ioprint(myvariable, someothervariable, yetanothervariable)

isAnsiBgColor

isAnsiBgColor(bgColorCode): This function tests if the first character of the current selection in the main console has the background color specified by bgColorCode.

Parameters

bgColorCode:

A color code to test for, possible codes are:

0 = default text color
1 = light black
2 = dark black
3 = light red
4 = dark red
5 = light green
6 = dark green
7 = light yellow
8 = dark yellow
9 = light blue
10 = dark blue
11 = light magenta
12 = dark magenta
13 = light cyan
14 = dark cyan
15 = light white
16 = dark white

Example

selectString( matches[1], 1 )
if isAnsiBgColor( 5 ) then
    bg( "red" );
    resetFormat();
    echo( "yes, the background of the text is light green" )
else
    echo( "no sorry, some other background color" )
end

Note: The variable named matches[1] holds the matched trigger pattern - even in substring, exact match, begin of line substring trigger patterns or even color triggers that do not know about the concept of capture groups. Consequently, you can always test if the text that has fired the trigger has a certain color and react accordingly. This function is faster than using getBgColor() and then handling the color comparison in Lua.

Also note that the color code numbers are Mudlet specific, though they do represent the colors in the 16 ANSI color-set for the main console they are not in the same order and they additionally have the default background color in the zeroth position.

isAnsiFgColor

isAnsiFgColor(fgColorCode): This function tests if the first character of the current selection in the main console has the foreground color specified by fgColorCode.

Parameters

fgColorCode:

A color code to test for, possible codes are:

0 = default text color
1 = light black
2 = dark black
3 = light red
4 = dark red
5 = light green
6 = dark green
7 = light yellow
8 = dark yellow
9 = light blue
10 = dark blue
11 = light magenta
12 = dark magenta
13 = light cyan
14 = dark cyan
15 = light white
16 = dark white

Example

selectString( matches[1], 1 )
if isAnsiFgColor( 5 ) then
    bg( "red" );
    resetFormat();
    echo( "yes, the text is light green" )
else
    echo( "no sorry, some other foreground color" )
end

Note: The variable named matches[1] holds the matched trigger pattern - even in substring, exact match, begin of line substring trigger patterns or even color triggers that do not know about the concept of capture groups. Consequently, you can always test if the text that has fired the trigger has a certain color and react accordingly. This function is faster than using getFgColor() and then handling the color comparison in Lua.

Also note that the color code numbers are Mudlet specific, though they do represent the colors in the 16 ANSI color-set for the main console they are not in the same order and they additionally have the default foreground color in the zeroth position.

loadWindowLayout

loadWindowLayout(): Resets the layout of userwindows (floating miniconsoles) to the last saved state.

Available in Mudlet3.2+

Example

loadWindowLayout()

lowerWindow

lowerWindow(labelName): Moves the referenced label/console below all other labels/consoles. For the opposite effect, see: raiseWindow().

Parameters

labelName:

the name of the label/console you wish to move below the rest.

Available in Mudlet3.1+

Example

createLabel("blueLabel", 300, 300, 100, 100, 1)   --creates a blue label
setBackgroundColor("blueLabel", 50, 50, 250, 255)

createLabel("redLabel", 350, 350, 100, 100, 1)    --creates a red label which is placed on TOP of the blue label, as the last made label will sit at the top of the rest
setBackgroundColor("redLabel", 250, 50, 50, 255)

lowerWindow("redLabel")                          --lowers redLabel, causing blueLabel to be back on top

moveCursor

moveCursor([windowName], x, y): Moves the user cursor of the window windowName, or the main window, to the absolute point (x,y). This function returns false if such a move is impossible e.g. the coordinates don’t exist. To determine the correct coordinates use getLineNumber(), getColumnNumber() and getLastLineNumber(). The trigger engine will always place the user cursor at the beginning of the current line before the script is run. If you omit the windowName argument, the main screen will be used.

Returns true or false depending on if the cursor was moved to a valid position. Check this before doing further cursor operations - because things like deleteLine() might invalidate this.

Parameters

windowName:

(optional) The window you are going to move the cursor in.

x:

The horizontal axis in the window - that is, the letter position within the line.

y:

The vertical axis in the window - that is, the line number.

Example

-- move cursor to the start of the previous line and insert -<(
-- the first 0 means we want the cursor right at the start of the line,
-- and getLineNumber()-1 means we want the cursor on the current line# - 1 which
-- equals to the previous line
moveCursor(0, getLineNumber()-1)
insertText("-<(")

-- now we move the cursor at the end of the previous line. Because the
-- cursor is on the previous line already, we can use #getCurrentLine()
-- to see how long it is. We also just do getLineNumber() because getLineNumber()
-- returns the current line # the cursor is on
moveCursor(#getCurrentLine(), getLineNumber())
insertText(")>-")

-- finally, reset it to the end where it was after our shenaningans - other scripts
-- could expect the cursor to be at the end
moveCursorEnd()

-- a more complicated example showing how to work with Mudlet functions

-- set up the small system message window in the top right corner
-- determine the size of your screen
local WindowWidth, WindowHeight = getMainWindowSize()

-- define a mini console named "sys" and set its background color
createMiniConsole("sys",WindowWidth-650,0,650,300)
setBackgroundColor("sys",85,55,0,255)

-- you *must* set the font size, otherwise mini windows will not work properly
setMiniConsoleFontSize("sys", 12)
-- wrap lines in window "sys" at 65 characters per line
setWindowWrap("sys", 60)
-- set default font colors and font style for window "sys"
setTextFormat("sys",0,35,255,50,50,50,0,0,0)
-- clear the window
clearUserWindow("sys")

moveCursorEnd("sys")
setFgColor("sys", 10,10,0)
setBgColor("sys", 0,0,255)
echo("sys", "test1---line1\n<this line is to be deleted>\n<this line is to be deleted also>\n")
echo("sys", "test1---line2\n")
echo("sys", "test1---line3\n")
setTextFormat("sys",158,0,255,255,0,255,0,0,0);
--setFgColor("sys",255,0,0);
echo("sys", "test1---line4\n")
echo("sys", "test1---line5\n")
moveCursor("sys", 1,1)

-- deleting lines 2+3
deleteLine("sys")
deleteLine("sys")

-- inserting a line at pos 5,2
moveCursor("sys", 5,2)
setFgColor("sys", 100,100,0)
setBgColor("sys", 255,100,0)
insertText("sys","############## line inserted at pos 5/2 ##############")

-- inserting a line at pos 0,0
moveCursor("sys", 0,0)
selectCurrentLine("sys")
setFgColor("sys", 255,155,255)
setBold( "sys", true );
setUnderline( "sys", true )
setItalics( "sys", true )
insertText("sys", "------- line inserted at: 0/0 -----\n")

setBold( "sys", true )
setUnderline( "sys", false )
setItalics( "sys", false )
setFgColor("sys", 255,100,0)
setBgColor("sys", 155,155,0)
echo("sys", "*** This is the end. ***\n")

(optional) name of the miniconsole/userwindow, or "main" for the main window.

Example

Need example

moveGauge

moveGauge(gaugeName, newX, newY): Moves a gauge created with createGauge to the new x,y coordinates. Remember the coordinates are relative to the top-left corner of the output window.

Parameters

gaugeName:

The name of your gauge

newX:

The horizontal pixel location

newY:

The vertical pixel location

Example

-- This would move the health bar gauge to the location 1200, 400
moveGauge("healthBar", 1200, 400)

moveWindow

moveWindow(name, x, y): This function moves window name to the given x/y coordinate. The main screen cannot be moved. Instead you’ll have to set appropriate border values → preferences to move the main screen e.g. to make room for chat or information mini consoles, or other GUI elements. In the future moveWindow() will set the border values automatically if the name parameter is omitted.

Parameters

name:

The name of your window

newX:

The horizontal pixel location

newY:

The vertical pixel location

Note: Since Mudlet 3.7 this method can also be used on UserWindow consoles.

openUserWindow

openUserWindow(windowName, [restoreLayout], [autoDock], [dockingArea]): Opens a user dockable console window for user output e.g. statistics, chat etc. If a window of such a name already exists, nothing happens. You can move these windows (even to a different screen on a system with a multi-screen display), dock them on any of the four sides of the main application window, make them into notebook tabs or float them.

Parameters

windowName:

name of your window, it must be unique across ALL profiles if more than one is open (for multi-playing).

restoreLayout: (available in Mudlet 3.2+)

(optional) - only relevant, if false is provided. Then the window won't be restored to its last known position.

autoDock: (available in Mudlet 4.7+)

(optional) - only relevant, if false is provided. Then the window won't dock automatically at the corners.

dockingArea: (available in Mudlet 4.7+)

(optional) - the area your UserWindow will be docked at. possible docking areas your UserWindow will be created in (f" floating "t" top "b" bottom "r" right and "l" left). Docking area is "right" if not given any value.

Note: Since Mudlet version 3.2, Mudlet will automatically remember the window's last position.

Examples

openUserWindow("My floating window")
cecho("My floating window", "<red>hello <blue>bob!")

-- if you don't want Mudlet to remember its last position:
openUserWindow("My floating window", false)

paste

paste(windowName): Pastes the previously copied text including all format codes like color, font etc. at the current user cursor position. The copy() and paste() functions can be used to copy formated text from the main window to a user window without losing colors e. g. for chat windows, map windows etc.

Parameters

windowName:

The name of your window

pauseMovie

pauseMovie(label name)

Pauses the gif animation on the label

createLabel("myMovie",0,0,200,200,0)

-- puts the gif on the label and animates it
setMovie("myMovie", getMudletHomeDir().."/movie.gif")
--stops the animation
pauseMovie("myMovie")

prefix

prefix(text, [writingFunction], [foregroundColor], [backgroundColor], [windowName]): Prefixes text at the beginning of the current line when used in a trigger.

"writingFunction:"

optional parameter, allows the selection of different functions to be used to write the text, valid options are: echo, cecho, decho, and hecho.

"foregroundColor:"

optional parameter, allows a foreground color to be specified if using the echo function using a color name, as with the fg() function

"backgroundColor:"

optional parameter, allows a background color to be specified if using the echo function using a color name, as with the bg() function

"windowName:"

optional parameter, allows the selection a miniconsole or the main window for the line that will be prefixed
Example

-- Prefix the hours, minutes and seconds onto our prompt even though Mudlet has a button for that
prefix(os.date("%H:%M:%S "))
-- Prefix the time in red into a miniconsole named "my_console"
prefix(os.date("<red>%H:%M:%S<reset>", cecho, nil, nil, "my_console"))

print

print(text, some more text, ...): Prints text to the main window. Similar to echo(), but does not require a "\n" at the end for a newline and can print several items given to it. It cannot print whole tables - use display() for those. This function works similarly to the print() you will see in guides for Lua.

Parameters

text:

The information you want to display.
Example

print("hi!")
print(1,2,3)
print(myvariable, someothervariable, yetanothervariable)

raiseWindow

raiseWindow(labelName): Raises the referenced label/console above all over labels/consoles. For the opposite effect, see: lowerWindow().

uniqueName:

A unique identifier that the mouse event was registered under.

Returns

Returns True If the mouse event was removed successfully.

replace

replace([windowName], with, [keepcolor]): Replaces the currently selected text with the new text. To select text, use selectString(), selectSection() or a similar function.

Note: If you’d like to delete/gag the whole line, use deleteLine() instead.

Note: when used outside of a trigger context (for example, in a timer instead of a trigger), replace() won't trigger the screen to refresh. Instead, use replace("") and insertText("new text") as insertText() does.

Parameters

what:

the text to replace

Note: This accepts Lua patterns

replaceAll("south", "north")

-- replace all occurrences of the text that the variable "target" has
replaceAll(target, "The Bad Guy")

replaceLine

replaceLine ([window], text): Replaces the output line from the game with your own text.

replaceWildcard

replaceWildcard(which, replacement, [keepcolor]): Replaces the given wildcard (as a number) with the given text. Equivalent to doing:

resetBackgroundImage

resetBackgroundImage([windowName]): Resets the console background-image
Parameters

windowName

(optional) name of the console the image will be reset

resetFormat([windowName]): Resets the colour/bold/italics formatting. Always use this function when done adjusting formatting, so make sure what you've set doesn't 'bleed' onto other triggers/aliases.

Parameters

windowName

(optional) name of the console to reset formatting. Defaults to "main" if missing.

Example

-- select and set the 'Tommy' to red in the line
if selectString("Tommy", 1) ~= -1 then fg("red") end

-- now reset the formatting, so our echo isn't red
resetFormat()
echo(" Hi Tommy!")

-- another example: just highlighting some words

scaleMovie(label name, [autoscale]): Resizes the gif to fill the full size of its label

selectCaptureGroup

selectCaptureGroup(groupNumber): Selects the content of the capture group number in your Perl regular expression (from matches[]). Also works with named capture group. It does not work with multimatches.

selectCmdLineText

selectCmdLineText([commandLine]): Selects the text in your command line. You can specify which one, if you got many.

selectCurrentLine

selectCurrentLine([windowName]): Selects the content of the current line that the cursor at. By default, the cursor is at the start of the current line that the triggers are processing, but you can move it with the moveCursor() function.

Note: This selects the whole line, including the linebreak - so it has a subtle difference from the slightly slower selectString(line, 1) selection method.

Parameters

windowName:

(optional) name of the window in which to select text.

Example

-- color the whole line green!
selectCurrentLine()
fg("green")
deselect()
resetFormat()

-- to select the previous line, you can do this:
moveCursor(0, getLineNumber()-1)
selectCurrentLine()

-- to select two lines back, this:
moveCursor(0, getLineNumber()-2)
selectCurrentLine()

selectSection

selectSection( [windowName], fromPosition, length ): Selects the specified parts of the line starting from the left and extending to the right for however how long. The line starts from 0.; Returns true if the selection was successful, and false if the line wasn't actually long enough or the selection couldn't be done in general.

Parameters

"windowName:"

(optional) name of the window in which to select text. By default the main window, if no windowName is given.

Will not work if "main" is given as the windowName to try to select from the main window.

fromPosition:

number to specify at which position in the line to begin selecting

length:

number to specify the amount of characters you want to select

Example

-- select and colour the first character in the line red
if selectSection(0,1) then fg("red") end

-- select and colour the second character green (start selecting from the first character, and select 1 character)
if selectSection(1,1) then fg("green") end

-- select and colour three character after the first two grey (start selecting from the 2nd character for 3 characters long)
if selectSection(2,3) then fg("grey") end

selectString

selectString([windowName], text, number_of_match): Selects a substring from the line where the user cursor is currently positioned - allowing you to edit selected text (apply colour, make it be a link, copy to other windows or other things).

Note: You can move the user cursor with moveCursor(). When a new line arrives from the game, the user cursor is positioned at the beginning of the line. However, if one of your trigger scripts moves the cursor around you need to take care of the cursor position yourself and make sure that the cursor is in the correct line if you want to call one of the select functions. To deselect text, see deselect().

setAppStyleSheet

setAppStyleSheet(stylesheet [, tag]): Sets a stylesheet for the entire Mudlet application and every open profile. Because it affects other profiles that might not be related to yours, it's better to use setProfileStyleSheet() instead of this function.

Raises the sysAppStyleSheetChange event which comes with two arguments in addition to the event name. The first is the optional tag which was passed into the function, or "" if nothing was given. The second is the profile which made the stylesheet changes.

setBackgroundColor

setBackgroundColor([windowName], r, g, b, [transparency]): Sets the background for the given label, miniconsole, or userwindow. Colors are from 0 to 255 (0 being black), and transparency is from 0 to 255 (0 being completely transparent).

Parameters

windowName:

setBackgroundColor("some label",255,0,0,200)

setBackgroundImage

setBackgroundImage(labelName, imageLocation)
setBackgroundImage([windowname], imageLocation, [mode]): Loads an image file (png) as a background image for a label or console. This can be used to display clickable buttons in combination with setLabelClickCallback() and such.

Note: You can also load images on labels via setLabelStyleSheet().

Parameters (label)

labelName:

The name of the label to change it's background color.

imageLocation:

The full path to the image location. It's best to use [[ ]] instead of "" for it - because for Windows paths, backslashes need to be escaped.

Parameters (consoles)

windowName:

(optional) name of the miniconsole/userwindow to change the background image on, or "main" for the main window.

imageLocation:

The full path to the image location. It's best to use [[ ]] instead of "" for it - because for Windows paths, backslashes need to be escaped.

If you have selected text prior to this call, the selection will be highlighted otherwise the current text background color will be changed. If you set a foreground or background color, the color will be used until you call resetFormat() on all further print commands.

If you'd like to change the background color of a window, see setBackgroundColor().

See also: cecho(), setBackgroundColor()

Optional parameter set the current text background color in windowname given.

boolean:

A true or false that enables or disables bolding of text

Example

-- enable bold formatting
setBold(true)

These additional components can take up to 30% of the screen size (400px when getMainWindowSize() was returning 1216px width). Don't go too aggressive with the numbers at first otherwise it will push elements off screen. Moving the command line over 250px on the above monitor also needed modifying of the width and max-width CSS properties. setCmdLineStyleSheet("main", [[QPlainTextEdit {margin-left: 250px; max-width: 562px; width: 562px}]])

-- inside.
createLabel("test", 50, 50, 100, 100, 0)
setLabelStyleSheet("test", [[
  background-color: white;
  border: 10px solid green;
  font-size: 12px;
  ]])
echo("test", "test")

-- This creates a label with a single image, that will tile or clip depending on the
-- size of the label. To use this example, please supply your own image.
createLabel("test5", 50, 353, 164, 55, 0)
setLabelStyleSheet("test5", [[
  background-image: url("C:/Users/Administrator/.config/mudlet/profiles/Midkemia Online/Vyzor/MkO_logo.png");

Parameters

labelName:

Name of the label which you want the mouse cursor change at.

cursorShape

Shape of the mouse cursor. List of possible cursor shapes is available here.
Example

setLabelCursor("myLabel", "Cross")
-- This will change the mouse cursor to a cross if it's over the label myLabel

setLabelCustomCursor

setLabelCustomCursor(labelName, custom cursor, [hotX, hotY]): Changes the mouse cursor shape over your label to a custom cursor. To reset the cursor shape, use resetLabelCursor().

Available in Mudlet4.8+

Parameters

labelName:

Name of the label which you want the mouse cursor change at.

custom cursor

Location of your custom cursor file. To be compatible with all systems it is recommended to use png files with size of 32x32.

hotX

X-coordinate of the cursors hotspot position. Optional, if not set it is set to -1 which is in the middle of your custom cursor.

hotY

setLabelWheelCallback

setLabelWheelCallback(labelName, luaFunctionName, [any arguments]): Specifies a Lua function to be called when the mouse wheel is scrolled while inside the specified label/console. This function can pass any number of string or integer number values as additional parameters. These parameters are then used in the callback - thus you can associate data with the label/button. Additionally, this function passes an event table as the final argument, similar to setLabelClickCallback(), but with slightly different information.; For this callback, the event argument has the following structure:

event = {
  x = 100,
  y = 200,
  globalX = 300,
  globalY = 320,
  buttons = {"RightButton", "MidButton"},
  angleDeltaX = 0,
  angleDeltaY = 120
}

Keys angleDeltaX and angleDeltaY correspond with the horizontal and vertical scroll distance, respectively. For most mice, these values will be multiples of 120.

Parameters

labelName:

The name of the label to attach a callback function to.

luaFunctionName:

The Lua function name to call, as a string.

any arguments:

(optional) Any amount of arguments you'd like to pass to the calling function.

Available in Mudlet3.6+

Example

function onWheelNorth(event)
  if event.angleDeltaY > 0 then
    echo("the north button was wheeled forwards over!")
  else
    echo("the north button was wheeled backwards over!")
  end
end

setLabelWheelCallback( "compassNorthImage", "onWheelNorth" )

-- you can also use them within tables:
mynamespace = {
  onWheelNorth = function()
    echo("the north button was wheeled over!")
  end
}

setWheelReleaseCallback( "compassNorthImage", "mynamespace.onWheelNorth" )

setLink

setLink([windowName], command, tooltip): Turns the selected text into a clickable link - upon being clicked, the link will do the command code. Tooltip is a string which will be displayed when the mouse is over the selected text.

Parameters

windowName:

(optional) name of a miniconsole or a userwindow in which to select the text in.

command:

command to do when the text is clicked, as text or Lua function.

tooltip:

-- perl regex trigger:
-- ^You just received message #(\w+) from \w+\.$
-- script:
selectString(matches[2], 1)
setUnderline(true) setLink([[send("msg read ]]..matches[2]..[[")]], "Read #"..matches[2])
resetFormat()

-- example of selecting text in a miniconsole and turning it into a link:
HelloWorld = Geyser.MiniConsole:new({
  name="HelloWorld",
  x="70%", y="50%",

setMovieSpeed("myMovie",150)

setOverline

setOverline([windowName], boolean): Sets the current text font to be overlined (true) or not overlined (false) mode. If the windowName parameters omitted, the main screen will be used. If you've got text currently selected in the Mudlet buffer, then the selection will be overlined. Any text you add after with echo() or insertText() will be overlined until you use resetFormat().

windowName:

(optional) name of the window to set the text to be overlined or not.

boolean:

A true or false that enables or disables overlining of text

Example

-- enable overlined text
setOverline(true)
-- the following echo will be have an overline
echo("hi")
-- turns off bolding, italics, underlines, colouring, and strikethrough (and, after this and reverse have been added, them as well). It's good practice to clean up after you're done with the formatting, so other your formatting doesn't "bleed" into other echoes.
resetFormat()

Available in Mudlet3.17+

setPopup

setPopup([windowName], {lua code}, {hints}): Turns the selected() text into a left-clickable link, and a right-click menu for more options. The selected text, upon being left-clicked, will do the first command in the list. Upon being right-clicked, it'll display a menu with all possible commands. The menu will be populated with hints, one for each line.

Parameters

windowName:

the name of the console to operate on. If not using this in a miniConsole, use "main" as the name.

This argument was ignored before Mudlet 4.11.

{lua code}:

a table of lua code to do, in text strings or as functions (since Mudlet 4.11), i.e. {[[send("hello")]], function() echo("hi!") end}

{hints}:

a table of strings which will be shown on the popup and right-click menu. ie, {"send the hi command", "echo hi to yourself"}.

Example

-- In a `Raising your hand in greeting, you say "Hello!"` exact match trigger,
-- the following code will make left-clicking on `Hello` show you an echo, while right-clicking
-- will show some commands you can do.

selectString("Hello", 1)
setPopup("main", {function() send("bye") end, function() echo("hi!") end}, {"send 'bye' to the MUD", "click to echo 'hi!'"})

-- alternatively, put command as text (in [[ and ]] to use quotation marks inside)
setPopup("main", {[[send("bye")]], [[echo("hi!")]]}, {"send 'bye' to the MUD", "click to echo 'hi!'"})

setProfileStyleSheet

setProfileStyleSheet(stylesheet): Sets a stylesheet for the current Mudlet profile - allowing you to customise content outside of the main window (the profile tabs, the scrollbar, and so on). This function is better than setAppStyleSheet() because it affects only the current profile and not every other one as well.

setReverse

setReverse([windowName], boolean): Sets the current text to swap foreground and background color settings (true) or not (false) mode. If the windowName parameters omitted, the main screen will be used. If you've got text currently selected in the Mudlet buffer, then the selection will have it's colors swapped. Any text you add after with echo() or insertText() will have their foreground and background colors swapped until you use resetFormat().

windowName:

(optional) name of the window to set the text colors to be reversed or not.

boolean:

A true or false that enables or disables reversing of the fore- and back-ground colors of text

Example

-- enable fore/back-ground color reversal of text
setReverse(true)
-- the following echo will have the text colors reversed
echo("hi")
-- turns off bolding, italics, underlines, colouring, and strikethrough (and, after this and overline have been added, them as well). It's good practice to clean up after you're done with the formatting, so other your formatting doesn't "bleed" into other echoes.
resetFormat()

Available in Mudlet3.17+

Note: Although the visual effect on-screen is the same as that of text being selected if both apply to a piece of text they neutralise each other - however the effect of the reversal will be carried over in copies made by the "Copy to HTML" and in logs made in HTML format log file mode.

setStrikeOut

setStrikeOut([windowName], boolean): Sets the current text font to be striken out (true) or not striken out (false) mode. If the windowName parameters omitted, the main screen will be used. If you've got text currently selected in the Mudlet buffer, then the selection will be bolded. Any text you add after with echo() or insertText() will be striken out until you use resetFormat().

windowName:

(optional) name of the window to set the text to be stricken out or not.

boolean:

A true or false that enables or disables striking out of text

Example

-- enable striken-out text
setStrikeOut(true)
-- the following echo will be have a strikethrough
echo("hi")
-- turns off bolding, italics, underlines, colouring, and strikethrough. It's good practice to clean up after you're done with the formatting, so other your formatting doesn't "bleed" into other echoes.
resetFormat()

setTextFormat

setTextFormat(windowName, r1, g1, b1, r2, g2, b2, bold, underline, italics, [strikeout], [overline], [reverse]): Sets current text format of selected window. This is a more convenient means to set all the individual features at once compared to using setFgColor(windowName, r,g,b), setBold(windowName, true), setItalics(windowName, true), setUnderline(windowName, true), setStrikeOut(windowName, true).; See Also: getTextFormat()

Parameters

windowName

Specify name of selected window. If empty string "" or "main" format will be applied to the main console

r1,g1,b1

To color text background, give number values in RBG style

r2,g2,b2

To color text foreground, give number values in RBG style

bold

To format text bold, set to 1 or true, otherwise 0 or false

underline

To underline text, set to 1 or true, otherwise 0 or false

italics

To format text italic, set to 1 or true, otherwise 0 or false

strikeout

(optional) To strike text out, set to 1 or true, otherwise 0 or false or simply no argument

overline

(optional) To use overline, set to 1 or true, otherwise 0 or false or simply no argument

reverse

(optional) To swap foreground and background colors, set to 1 or true, otherwise 0 or false or simply no argument

Example

--This script would create a mini text console and write with bold, struck-out, yellow foreground color and blue background color "This is a test".
createMiniConsole( "con1", 0,0,300,100);
setTextFormat("con1",0,0,255,255,255,0,true,0,false,1);
echo("con1","This is a test")

Note: In versions prior to 3.7.0 the error messages and this wiki were wrong in that they had the foreground color parameters as r1, g1 and b1 and the background ones as r2, g2 and b2.

setUnderline

setUnderline(windowName, bool): Sets the current text font to underline/non-underline mode. If the windowName parameters omitted, the main screen will be used.

end

Additional development notes

wrapLine

wrapLine(windowName, lineNumber): wraps the line specified by lineNumber of mini console (window) windowName. This function will interpret \n characters, apply word wrap and display the new lines on the screen. This function may be necessary if you use deleteLine() and thus erase the entire current line in the buffer, but you want to do some further echo() calls after calling deleteLine(). You will then need to re-wrap the last line of the buffer to actually see what you have echoed and get your \n interpreted as newline characters properly. Using this function is no good programming practice and should be avoided. There are better ways of handling situations where you would call deleteLine() and echo afterwards e.g.:

selectString(line,1)
replace("")

This will effectively have the same result as a call to deleteLine() but the buffer line will not be entirely removed. Consequently, further calls to echo() etc. sort of functions are possible without using wrapLine() unnecessarily.
