+ | |||
+ | ; sameValue = compare(a, b) | ||
+ | |||
+ | :This function takes two items, and compares their values. It will compare numbers, strings, but most importantly it will compare two tables by value, not reference. For instance, ''{} == {}'' is ''false'', but ''compare({}, {})'' is ''true'' | ||
+ | |||
+ | ;See also: [[Manual:Lua_Functions#table.complement|table.complement()]], [[Manual:Lua_Functions#table.n_union|table.n_union()]] | ||

+ | {{MudletVersion|4.18}} | ||
+ | |||
+ | ;Parameters | ||
+ | * ''a:'' | ||
+ | : The first item to compare | ||
+ | * ''b:'' | ||
+ | : The second item to compare | ||
+ | |||
+ | ;Returns | ||
+ | * Boolean true if the items have the same value, otherwise boolean false | ||
+ | |||
+ | ;Example | ||
+ | <syntaxhighlight lang="lua"> | ||
+ | local tblA = { 255, 0, 0 } | ||
+ | local tblB = color_table.red | ||
+ | local same = compare(tblA, tblB) | ||
+ | display(same) | ||
+ | -- this will return true | ||
+ | display(tblA == tblB) | ||
+ | -- this will display false, as they are different tables | ||
+ | -- even though they have the same value | ||
+ | </syntaxhighlight> | ||

+ | ; Additional development notes | ||
+ | This is just exposing the existing _comp function, which is currently the best way to compare two tables by value. --[[User:Demonnic|Demonnic]] ([[User talk:Demonnic|talk]]) 18:51, 7 February 2024 (UTC) | ||

Miscellaneous Functions
addFileWatch
- addFileWatch(path)
- Adds file watch on directory or file. Every change in that file (or directory) will raise sysPathChanged event.
- See also: removeFileWatch()
- Example
herbs = {}
local herbsPath = getMudletHomeDir() .. "/herbs.lua"
function herbsChangedHandler(_, path)
if path == herbsPath then
table.load(herbsPath, herbs)
removeFileWatch(herbsPath)
end
end
addFileWatch(herbsPath)
registerAnonymousEventHandler("sysPathChanged", "herbsChangedHandler")
addSupportedTelnetOption
- addSupportedTelnetOption(option)
- Adds a telnet option, which when queried by a game server, Mudlet will return DO (253) on. Use this to register the telnet option that you will be adding support for with Mudlet - see additional protocols section for more.
- Example
<event handlers that add support for MSDP... see http://www.mudbytes.net/forum/comment/63920/#c63920 for an example>
-- register with Mudlet that it should not decline the request of MSDP support
local TN_MSDP = 69
addSupportedTelnetOption(TN_MSDP)
alert
- alert([seconds])
- alerts the user to something happening - makes Mudlet flash in the Windows window bar, bounce in the macOS dock, or flash on Linux.
- Parameters
- seconds:
- (optional) number of seconds to have the alert for. If not provided, Mudlet will flash until the user opens Mudlet again.
- Example
-- flash indefinitely until Mudlet is open
alert()
-- flash for just 3 seconds
alert(3)
cfeedTriggers
- cfeedTriggers(text)
- Like feedTriggers, but you can add color information using color names, similar to cecho.
- Parameters
- text: The string to feed to the trigger engine. Include colors by name as black,red,green,yellow,blue,magenta,cyan,white and light_* versions of same. You can also use a number to get the ansi color corresponding to that number.
- See also: feedTriggers
- Example
cfeedTriggers("<green:red>green on red<r> reset <124:100> foreground of ANSI124 and background of ANSI100<r>\n")
closeMudlet
- closeMudlet()
- Closes Mudlet and all profiles immediately.
- See also: saveProfile()
Note: Use with care. This potentially lead to data loss, if "save on close" is not activated and the user didn't save the profile manually as this will NOT ask for confirmation nor will the profile be saved. Also it does not consider if there are other profiles open if multi-playing: they all will be closed!
- Example
closeMudlet()
compare
- sameValue = compare(a, b)
- This function takes two items, and compares their values. It will compare numbers, strings, but most importantly it will compare two tables by value, not reference. For instance, {} == {} is false, but compare({}, {}) is true
- See also
- table.complement(), table.n_union()
- Parameters
- a:
- The first item to compare
- b:
- The second item to compare
- Returns
- Boolean true if the items have the same value, otherwise boolean false
- Example
local tblA = { 255, 0, 0 }
local tblB = color_table.red
local same = compare(tblA, tblB)
display(same)
-- this will return true
display(tblA == tblB)
-- this will display false, as they are different tables
-- even though they have the same value
- Additional development notes
This is just exposing the existing _comp function, which is currently the best way to compare two tables by value. --Demonnic (talk) 18:51, 7 February 2024 (UTC)
deleteAllNamedEventHandlers
- deleteAllNamedEventHandlers(userName)
- Deletes all named event handlers for userName and prevents them from firing any more. Information is deleted and cannot be retrieved.
- Parameters
- userName:
- The user name the event handler was registered under.
- Example
deleteAllNamedEventHandlers("Demonnic") -- emergency stop or debugging situation, most likely.
deleteNamedEventHandler
- success = deleteNamedEventHandler(userName, handlerName)
- Deletes a named event handler with name handlerName and prevents it from firing any more. Information is deleted and cannot be retrieved.
- Parameters
- userName:
- The user name the event handler was registered under.
- handlerName:
- The name of the handler to stop. Same as used when you called registerNamedEventHandler()
- Returns
- true if successful, false if it didn't exist
- Example
local deleted = deleteNamedEventHandler("Demonnic", "Vitals")
if deleted then
cecho("Vitals deleted forever!!")
else
cecho("Vitals doesn't exist and so could not be deleted.")
end
denyCurrentSend
- denyCurrentSend()
- Cancels a send() or user-entered command, but only if used within a sysDataSendRequest event.
- Example
-- cancels all "eat hambuger" commands
function cancelEatHamburger(event, command)
if command == "eat hamburger" then
denyCurrentSend()
cecho("<red>Denied! Didn't let the command through.\n")
end
end
registerAnonymousEventHandler("sysDataSendRequest", "cancelEatHamburger")
dfeedTriggers
- dfeedTriggers(str)
- Like feedTriggers, but you can add color information using <r,g,b>, similar to decho.
- Parameters
- str: The string to feed to the trigger engine. Include color information inside tags like decho.
- See also
- cfeedTriggers, decho
- Example
dfeedTriggers("<0,128,0:128,0,0>green on red<r> reset\n")
disableModuleSync
- disableModuleSync(name)
- Stops syncing the given module.
- Parameter
- name: name of the module.
- See also: enableModuleSync(), getModuleSync()
enableModuleSync
- enableModuleSync(name)
- Enables the sync for the given module name - any changes done to it will be saved to disk and if the module is installed in any other profile(s), it'll be updated in them as well on profile save.
- Parameter
- name: name of the module to enable sync on.
- See also: disableModuleSync(), getModuleSync()
expandAlias
- expandAlias(command, [echoBackToBuffer])
- Runs the command as if it was from the command line - so aliases are checked and if none match, it's sent to the game unchanged.
- Parameters
- command
- Text of the command you want to send to the game. Will be checked for aliases.
- echoBackToBuffer
- (optional) If false, the command will not be echoed back in your buffer. Defaults to true if omitted.
Note: Using expandAlias is not recommended anymore as it is not very robust and may lead to problems down the road. The recommendation is to use lua functions instead. See Manual:Functions_vs_expandAlias for details and examples.
Note: If you want to be using the matches table after calling expandAlias, you should save it first, as, e.g. local oldmatches = matches before calling expandAlias, since expandAlias will overwrite it after using it again.
Note: Since Mudlet 3.17.1 the optional second argument to echo the command on screen will be ineffective whilst the game server has negotiated the telnet ECHO option to provide the echoing of text we send to him.
- Example
expandAlias("t rat")
-- don't echo the command
expandAlias("t rat", false)
feedTriggers
- feedTriggers(text[, dataIsUtf8Encoded = true])
- This function will have Mudlet parse the given text as if it came from the game - one great application is trigger testing. The built-in `echo alias provides this functionality as well.
- Parameters
- text:
- string which is sent to the trigger processing system almost as if it came from the game server. This string must be byte encoded in a manner to match the currently selected Server Encoding.
- dataIsUtf8Encoded (available in Mudlet 4.2+):
- Set this to false, if you need pre-Mudlet 4.0 behavior. Most players won't need this.
- (Before Mudlet 4.0 the text had to be encoded directly in whatever encoding the setting in the preferences was set to.
- (Encoding could involve using the Lua string character escaping mechanism of \ and a base 10 number for character codes from \1 up to \255 at maximum)
- Since Mudlet 4.0 it is assumed that the text is UTF-8 encoded. It will then be automatically converted to the currently selected game server encoding.
- Preventing the automatic conversion can be useful to Mudlet developers testing things, or possibly to those who are creating handlers for Telnet protocols within the Lua subsystem, who need to avoid the transcoding of individual protocol bytes, when they might otherwise be seen as extended ASCII characters.)
- Returns (available in Mudlet 4.2+)
- true on success, nil and an error message if the text contains characters that cannot be conveyed by the current Game Server encoding.
Note: It is important to ensure that in Mudlet 4.0.0 and beyond the text data only contains characters that can be encoded in the current Game Server encoding, from 4.2.0 the content is checked that it can successfully be converted from the UTF-8 that the Mudlet Lua subsystem uses internally into that particular encoding and if it cannot the function call will fail and not pass any of the data, this will be significant if the text component contains any characters that are not plain ASCII.
- Example
-- try using this on the command line
`echo This is a sample line from the game
-- You can use \n to represent a new line - you also want to use it before and after the text you’re testing, like so:
feedTriggers("\nYou sit yourself down.\n")
-- The function also accept ANSI color codes that are used in games. A sample table can be found http://codeworld.wikidot.com/ansicolorcodes
feedTriggers("\nThis is \27[1;32mgreen\27[0;37m, \27[1;31mred\27[0;37m, \27[46mcyan background\27[0;37m," ..
"\27[32;47mwhite background and green foreground\27[0;37m.\n")
getCharacterName
- getCharacterName()
- Returns the name entered into the "Character name" field on the Connection Preferences form. Can be used to find out the name that might need to be handled specially in scripts or anything that needs to be personalized to the player. If there is nothing set in that entry will return an empty string.
- See also: getProfileName()
- Example
-- cast glamor on yourself
send("cast 'glamor' " .. getCharacterName())
getConfig
- getConfig([option])
- Returns configuration options similar to those that can be set with setConfig. One could use this to decide if a script should notify the user of suggested changes.

- Returns
- It returns a table of options or the value of a single option requested. They are only the configuration options, for example "enableGMCP" means that the "Enable GMCP" box is checked and does not mean that it has been negotiated with the server.
- Example
getConfig()
-- Suggest enabling GMCP if it is unchecked
if not getConfig("enableGMCP") then
echo("\nMy script works best with GMCP enabled. You may ")
cechoLink("<red>click here", function() setConfig("enableGMCP",true) echo("GMCP enabled\n") end, "Enable GMCP", true)
echo(" to enable it.\n")
end
getModulePath
- path = getModulePath(module name)
- Returns the location of a module on the disk. If the given name does not correspond to an installed module, it'll return
nil
- See also: installModule()
- Example
getModulePath("mudlet-mapper")
getModulePriority
- priority = getModulePriority(module name)
- Returns the priority of a module as an integer. This determines the order modules will be loaded in - default is 0. Useful if you have a module that depends on another module being loaded first, for example.
- Modules with priority
-1
will be loaded before scripts (Mudlet 4.11+).
- See also: setModulePriority()
- Example
getModulePriority("mudlet-mapper")
getModules
- getModules()
- Returns installed modules as table.
- See also: getPackages
- Example
--Check if the module myTabChat is installed and if it isn't install it and enable sync on it
if not table.contains(getModules(),"myTabChat") then
installModule(getMudletHomeDir().."/modules/myTabChat.xml")
enableModuleSync("myTabChat")
end
getModuleInfo
- getModuleInfo(moduleName, [info])
- Returns table with meta information for a package
- Parameters
- moduleName:
- Name of the package
- info:
- (optional) specific info wanted to get, if not given all available meta-info is returned
- See also: getPackageInfo, setModuleInfo
- Example
getModuleInfo("myModule","author")
getModuleSync
- getModuleSync(name)
- returns false if module sync is not active, true if it is active and nil if module is not found.
- Parameter
- name: name of the module
- See also: enableModuleSync(), disableModuleSync()
getMudletHomeDir
- getMudletHomeDir()
- Returns the current home directory of the current profile. This can be used to store data, save statistical information, or load resource files from packages.
Note: intentionally uses forward slashes /
as separators on Windows since stylesheets require them.
- Example
-- save a table
table.save(getMudletHomeDir().."/myinfo.dat", myinfo)
-- or access package data. The forward slash works even on Windows fine
local path = getMudletHomeDir().."/mypackagename"
getMudletInfo
- getMudletInfo()
- Prints debugging information about the Mudlet that you're running - this can come in handy for diagnostics.
Don't use this command in your scripts to find out if certain features are supported in Mudlet - there are better functions available for this.
- Example
getMudletInfo()
getMudletVersion
- getMudletVersion(style)
- Returns the current Mudlet version. Note that you shouldn't hardcode against a specific Mudlet version if you'd like to see if a function is present - instead, check for the existence of the function itself. Otherwise, checking for the version can come in handy if you'd like to test for a broken function or so on.
See also: mudletOlderThan()
- Parameters
- style:
- (optional) allows you to choose what you'd like returned. By default, if you don't specify it, a key-value table with all the values will be returned: major version, minor version, revision number and the optional build name.
- Values you can choose
- "string":
- Returns the full Mudlet version as text.
- "table":
- Returns the full Mudlet version as four values (multi-return)
- "major":
- Returns the major version number (the first one).
- "minor":
- Returns the minor version number (the second one).
- "revision":
- Returns the revision version number (the third one).
- "build":
- Returns the build of Mudlet (the ending suffix, if any).
- Example
-- see the full Mudlet version as text:
getMudletVersion("string")
-- returns for example "3.0.0-alpha"
-- check that the major Mudlet version is at least 3:
if getMudletVersion("major") >= 3 then echo("You're running on Mudlet 3+!") end
-- but mudletOlderThan() is much better for this:
if mudletOlderThan(3) then echo("You're running on Mudlet 3+!") end
-- if you'd like to see if a function is available however, test for it explicitly instead:
if setAppStyleSheet then
-- example credit to http://qt-project.org/doc/qt-4.8/stylesheet-examples.html#customizing-qscrollbar
setAppStyleSheet[[
QScrollBar:vertical {
border: 2px solid grey;
background: #32CC99;

echo(getProfileName())
getCommandSeparator
- getCommandSeparator()
- Returns the command separator in use by the profile.
- Example
-- if your command separator is ;;, the following would send("do thing 1;;do thing 2").
-- This way you can determine what it is set to and use that and share this script with
-- someone who has changed their command separator.
-- Note: This is not really the preferred way to send this, using sendAll("do thing 1", "do thing 2") is,
-- but this illustates the use case.
local s = getCommandSeparator()
expandAlias("do thing 1" .. s .. "do thing 2")
getServerEncoding
- getServerEncoding()
- Returns the current server data encoding in use.
- See also: setServerEncoding(), getServerEncodingsList()
- Example
getServerEncoding()
getServerEncodingsList
- getServerEncodingsList()
- Returns an indexed list of the server data encodings that Mudlet knows. This is not the list of encodings the servers knows - there's unfortunately no agreed standard for checking that. See encodings in Mudlet for the list of which encodings are available in which Mudlet version.
- See also: setServerEncoding(), getServerEncoding()
- Example
-- check if UTF-8 is available:
if table.contains(getServerEncodingsList(), "UTF-8") then
print("UTF-8 is available!")
end
getWindowsCodepage
- getWindowsCodepage()
- Returns the current codepage of your Windows system.
Note: This function only works on Windows - It is only needed internally in Mudlet to enable Lua to work with non-ASCII usernames (e.g. Iksiński, Jäger) for the purposes of IO. Linux and macOS work fine with with these out of the box.
- Example
print(getWindowsCodepage())
hfeedTriggers
- hfeedTriggers(str)
- Like feedTriggers, but you can add color information using #RRGGBB in hex, similar to hecho.
- Parameters
- str: The string to feed to the trigger engine. Include color information in the same manner as hecho.
- See also: dfeedTriggers
- See also: hecho
- Example
hfeedTriggers("#008000,800000green on red#r reset\n")
holdingModifiers
- holdingModifiers(number)
- Returns true or false depending on whether a particular modifier key is being held at the time this function is run. Can be paired with a number of actions, including clicking on a label.
- Parameters
- number: A number corresponding to a specific modifier key.
- Modifiers
Modifier values can be found by accessing the global `mudlet.keymodifier` table, which, as of 4.18, provides for the following:
{
Alt = 134217728,
Control = 67108864,
GroupSwitch = 1073741824,
Keypad = 536870912,
Meta = 268435456,
None = 0,
Shift = 33554432
}
- Example
local MyLabel = MyLabel or Geyser.Label:new({
name = "MyLabel",
x = 0,y = 0,
height = 200, width = 100,
message = "This is my label"
})
function clickity(...)
display(...)
for k, v in spairs(mudlet.keymodifier) do
print(f[[Holding down {k} : {holdingModifiers(v)}]])
end
end
setLabelClickCallback("MyLabel", "clickity")
-- Result:
--
-- Holding down Alt : true
-- Holding down Control : false
-- Holding down GroupSwitch : false
-- Holding down Keypad : false
-- Holding down Meta : false
-- Holding down None : false
-- Holding down Shift : false
- Notes
You may only test for one modifier key being held. If more than one modifier key is held down, then all results will be false.
installModule
- installModule(location)
- Installs a Mudlet XML, zip, or mpackage as a module.

mudletOlderThan
- mudletOlderThan(major, [minor], [patch])
- Returns true if Mudlet is older than the given version to check. This is useful if you'd like to use a feature that you can't check for easily, such as coroutines support. However, if you'd like to check if a certain function exists, do not use this and use
if mudletfunction then
- it'll be much more readable and reliable.
See also: getMudletVersion()
- Parameters
- major:
- Mudlet major version to check. Given a Mudlet version 3.0.1, 3 is the major version, second 0 is the minor version, and third 1 is the patch version.
- minor:
- (optional) minor version to check.
- patch:
- (optional) patch version to check.
- Example
-- stop doing the script of Mudlet is older than 3.2
if mudletOlderThan(3,2) then return end
-- or older than 2.1.3
if mudletOlderThan(2, 1, 3) then return end
-- however, if you'd like to check that a certain function is available, like getMousePosition(), do this instead:
if not getMousePosition then return end
-- if you'd like to check that coroutines are supported, do this instead:
if not mudlet.supports.coroutines then return end
openWebPage

purgeMediaCache
- purgeMediaCache()
- Purge all media file stored in the media cache within a given Mudlet profile (media used with MCMP and MSP protocols). As game developers update the media files on their games, this enables the media folder inside the profile to be cleared so that the media files could be refreshed to the latest update(s).
- Guidance
- Instruct a player to type lua purgeMediaCache() on the command line, or
- Distribute a trigger, button or other scriptable feature for the given profile to call purgeMediaCache()
- See also: Supported Protocols MSP, Scripting MCMP
receiveMSP
- receiveMSP(command)
- Receives a well-formed Mud Sound Protocol (MSP) message to be processed by the Mudlet client. Reference the Supported Protocols MSP manual for more information on about what can be sent and example triggers.
- See also: Supported Protocols MSP
- Example
--Play a cow.wav media file stored in the media folder of the current profile. The sound would play twice at a normal volume.
receiveMSP("!!SOUND(cow.wav L=2 V=50)")
--Stop any SOUND media files playing stored in the media folder of the current profile.
receiveMSP("!!SOUND(Off)")
--Play a city.mp3 media file stored in the media folder of the current profile. The music would play once at a low volume.
--The music would continue playing if it was triggered earlier by another room, perhaps in the same area.
receiveMSP([[!!MUSIC(city.mp3 L=1 V=25 C=1)]])
--Stop any MUSIC media files playing stored in the media folder of the current profile.
receiveMSP("!!MUSIC(Off)")
registerAnonymousEventHandler
- registerAnonymousEventHandler(event name, functionReference, [one shot])
- Registers a function to an event handler, not requiring you to set one up via script. See here for a list of Mudlet-raised events. The function may be refered to either by name as a string containing a global function name, or with the lua function object itself.
- The optional
one shot
parameter allows you to automatically kill an event handler after it is done by giving a true value. If the event you waited for did not occur yet, returntrue
from the function to keep it registered.
- The function returns an ID that can be used in killAnonymousEventHandler() to unregister the handler again.
- If you use an asterisk ("*") as the event name, your code will capture all events. Useful for debugging, or integration with external programs.
Note: The ability to refer lua functions directly, the one shot
parameter and the returned ID are features of Mudlet 3.5 and above.
Note: The "*" all-events capture was added in Mudlet 4.10.
- Example
-- example taken from the God Wars 2 (http://godwars2.org) Mudlet UI - forces the window to keep to a certain size
function keepStaticSize()
setMainWindowSize(1280,720)
end -- keepStaticSize
if keepStaticSizeEventHandlerID then killAnonymousEventHandler(keepStaticSizeEventHandlerID) end -- clean up any already registered handlers for this function
keepStatisSizeEventHandlerID = registerAnonymousEventHandler("sysWindowResizeEvent", "keepStaticSize") -- register the event handler and save the ID for later killing

registerNamedEventHandler
- success = registerNamedEventHandler(userName, handlerName, eventName, functionReference, [oneShot])
- Registers a named event handler with name handlerName. Named event handlers are protected from duplication and can be stopped and resumed, unlike anonymous event handlers. A separate list is kept per userName
- See also
- registerAnonymousEventHandler(), stopNamedEventHandler(), resumeNamedEventHandler(), deleteNamedEventHandler(), registerNamedTimer()
- Parameters
- userName:
- The user name the event handler was registered under.
- handlerName:
- The name of the handler. Used to reference the handler in other functions and prevent duplicates. Recommended you use descriptive names, "hp" is likely to collide with something else, "DemonVitals" less so.
- eventName:
- The name of the event the handler responds to. See here for a list of Mudlet-raised events.
- functionReference:
- The function reference to run when the event comes in. Can be the name of a function, "handlerFuncion", or the lua function itself.
- oneShot:
- (optional) if true, the event handler will only fire once when the event is raised. If you need to extend a one shot event handler for "one more check" you can have the handler return true, and it will keep firing until the function does not return true.
- Returns
- true if successful, otherwise errors.
- Example
-- register a named event handler. Will call demonVitalsHandler(eventName, ...) when gmcp.Char.Vitals is raised.
local ok = registerNamedEventHandler("Demonnic", "DemonVitals", "gmcp.Char.Vitals", "demonVitalsHandler")
if ok then
cecho("Vitals handler switched to demonVitalsHandler")
end
-- something changes later, and we want to handle vitals with another function, demonBlackoutHandler()
-- note we do not use "" around demonBlackoutHandler but instead pass the function itself. Both work.
-- using the same handlerName ("DemonVitals") means it will automatically unregister the old handler
-- and reregister it using the new information.
local ok = registerNamedEventHandler("Demonnic", "DemonVitals", "gmcp.Char.Vitals", demonBlackoutHandler)
if ok then
cecho("Vitals handler switched to demonBlackoutHandler")
end
-- Now you want to check your inventory, but you only want to do it once, so you pass the optional oneShot as true
local function handleInv()
local list = gmcp.Char.Items.List
if list.location ~= "inventory" then
return true -- if list.location is, say "room" then we need to keep responding until it's "inventory"
end
display(list.items) -- you would probably store values and update displays or something, but here I'll just show the data as it comes in
end
-- you can ignore the response from registerNamedEventHandler if you want, it's always going to be true
-- unless there is an error, in which case it throws the error and halts execution anyway. The return is
-- in part for feedback when using the lua alias or other REPL window.
registerNamedEventHandler("Demonnic", "DemonInvCheck", "gmcp.Char.Items.List", handleInv, true)
reloadModule
- reloadModule(module name)
- Reload a module (by uninstalling and reinstalling).
- See also: installModule(), uninstallModule()
- Example
reloadModule("3k-mapper")
removeFileWatch
- removeFileWatch(path)
- Remove file watch on directory or file. Every change in that file will no longer raise sysPathChanged event.
- See also: addFileWatch()
- Example
herbs = {}
local herbsPath = getMudletHomeDir() .. "/herbs.lua"
function herbsChangedHandler(_, path)
if path == herbsPath then
table.load(herbsPath, herbs)
removeFileWatch(herbsPath)
end
end
addFileWatch(herbsPath)
registerAnonymousEventHandler("sysPathChanged", "herbsChangedHandler")
resetProfile
- resetProfile()
- Reloads your entire Mudlet profile - as if you've just opened it. All UI elements will be cleared, so this useful when you're coding your UI.
- Example
resetProfile()
The function used to require input from the game to work, but as of Mudlet 3.20 that is no longer the case.
Note: Don't put resetProfile() in a script-item in the script editor as the script will be reloaded by resetProfile(), better to use the command line or alias.
Note: Developer tip: Make a keybinding for resetting your profile while you develop your GUI so you don't have to type lua resetProfile()
command every time you want to see the changes (e.g. CTRL+SHIFT+R)
resumeNamedEventHandler
- success = resumeNamedEventHandler(userName, handlerName)
- Resumes a named event handler with name handlerName and causes it to start firing once more.
- Parameters
- userName:
- The user name the event handler was registered under.
- handlerName:
- The name of the handler to resume. Same as used when you called registerNamedEventHandler()
- Returns
- true if successful, false if it didn't exist.
- Example
local resumed = resumeNamedEventHandler("Demonnic", "DemonVitals")
if resumed then
cecho("DemonVitals resumed!")
else
cecho("DemonVitals doesn't exist, cannot resume it")
end
saveProfile
- saveProfile(location)
- Saves the current Mudlet profile to disk, which is equivalent to pressing the "Save Profile" button.
- Parameters
- location:
- (optional) folder to save the profile to. If not given, the profile will go into the default location.
- Example
saveProfile()
-- save to the desktop on Windows:
saveProfile([[C:\Users\yourusername\Desktop]])
setConfig
- setConfig(option, value)
- Sets a Mudlet option to a certain value. This comes in handy for scripts that want to customise Mudlet settings to their preferences - for example, setting up mapper room and exit size to one that works for a certain map, or enabling MSDP for a certain game. For transparency reasons, the Debug window (when open) will show which options were modified by scripts.
- To set many options at once, pass in a table of options. More options will be added over time / per request.
- See also
- enableMapInfo(), disableMapInfo()

setConfig({mapRoomSize = 6, mapExitSize = 12})
setMergeTables
- setMergeTables(module)
- Makes Mudlet merge the table of the given GMCP or MSDP module instead of overwriting the data. This is useful if the game sends only partial updates which need combining for the full data. By default "Char.Status" is the only merged module.
- Parameters
- module:
- Name(s) of the GMCP or MSDP module(s) that should be merged as a string - this will add it to the existing list.
- Example
setMergeTables("Char.Skills", "Char.Vitals")
setModuleInfo

- Sets a specific meta info value for a module
- Parameters
- moduleName:
- Name of the module
- info:
- specific info to set (for example "version")
- value:
- specific value to set (for example "1.0")
- See also: getModuleInfo, getPackageInfo
- Example
setModuleInfo("myModule", "version", "1.0")
setModulePriority
- setModulePriority(moduleName, priority)
- Sets the module priority on a given module as a number - the module priority determines the order modules are loaded in, which can be helpful if you have ones dependent on each other. This can also be set from the module manager window.
- Modules with priority
-1
will be loaded before scripts (Mudlet 4.11+).
- See also: getModulePriority()
setModulePriority("mudlet-mapper", 1)
setPackageInfo
- setPackageInfo(packageName, info, value)
- Sets a specific meta info value for a package
- Parameters
- packageName:
- Name of the module
- info:
- specific info to set (for example "version")
- value:
- specific value to set (for example "1.0")
- See also: getPackageInfo, setModuleInfo
- Example
setPackageInfo("myPackage", "title", "This is my test package")
setServerEncoding
- setServerEncoding(encoding)
- Makes Mudlet use the specified encoding for communicating with the game.
- Parameters
- encoding:
- Encoding to use.
- See also: getServerEncodingsList(), getServerEncoding()
- Example
-- use UTF-8 if Mudlet knows it. Unfortunately there's no way to check if the game's server knows it too.
if table.contains(getServerEncodingsList(), "UTF-8") then
setServerEncoding("UTF-8")
end
showNotification
- showNotification(title, [content], [expiryTimeInSeconds])
- Shows a native (system) notification.
Note: This might not work on all systems, this depends on the system.
- Parameters
- title - plain text notification title
- content - optional argument, plain text notification content, if omitted title argument will be used as content as well
- expiryTimeInSeconds - optional argument, sets expiration time in seconds for notification, very often ignored by OS
showNotification("Notification title", "Notification content", 5)
spawn
- spawn(readFunction, processToSpawn[, ...arguments])
- Spawns a process and opens a communicatable link with it - read function is the function you'd like to use for reading output from the process, and t is a table containing functions specific to this connection - send(data), true/false = isRunning(), and close().
- This allows you to setup RPC communication with another process.
- Examples
-- simple example on a program that quits right away, but prints whatever it gets using the 'display' function
local f = spawn(display, "ls")
display(f.isRunning())
f.close()
local f = spawn(display, "ls", "-la")
display(f.isRunning())
f.close()
startLogging
- startLogging(state)
- Control logging of the main console text as text or HTML (as specified by the "Save log files in HTML format instead of plain text" setting on the "General" tab of the "Profile preferences" or "Settings" dialog). Despite being called startLogging it can also stop the process and correctly close the file being created. The file will have an extension of type ".txt" or ".html" as appropriate and the name will be in the form of a date/time "yyyy-MM-dd#hh-mm-ss" using the time/date of when logging started. Note that this control parallels the corresponding icon in the "bottom buttons" for the profile and that button can also start and stop the same logging process and will reflect the state as well.
- Parameters
- state:
- Required: logging state. Passed as a boolean
- Returns (4 values)
- successful (bool)
- true if the logging state actually changed; if, for instance, logging was already active and true was supplied then no change in logging state actually occurred and nil will be returned (and logging will continue).
- message (string)
- A displayable message given one of four messages depending on the current and previous logging states, this will include the file name except for the case when logging was not taking place and the supplied argument was also false.
- fileName (string)
- The log will be/is being written to the path/file name returned.
- code (number)
- A value indicating the response to the system to this instruction:
* 0 = logging has just stopped * 1 = logging has just started * -1 = logging was already in progress so no change in logging state * -2 = logging was already not in progress so no change in logging state
- Example
-- start logging
local success, message, filename, code = startLogging(true)
if code == 1 or code == -1 then print(f"Started logging to {filename}") end
-- stop logging
startLogging(false)
stopAllNamedEventHandlers
- stopAllNamedEventHandlers(userName)

timeframe
- timeframe(vname, true_time, nil_time, ...)
- A utility function that helps you change and track variable states without using a lot of tempTimers.
- Parameters
- vname:
- A string or function to use as the variable placeholder.
- true_time:
- Time before setting the variable to true. Can be a number or a table in the format:
{time, value}
- nil_time:
- (optional) Number of seconds until
vname
is set back to nil. Leaving it undefined will leave it at whatever it was set to last. Can be a number of a table in the format:{time, value}
- ...:
- (optional) Further list of times and values to set the variable to, in the following format:
{time, value}
- Example
-- sets the global 'limiter' variable to true immediately (see the 0) and back to nil in one second (that's the 1).
timeframe("limiter", 0, 1)
-- An angry variable 'giant' immediately set to "fee", followed every second after by "fi", "fo", and "fum" before being reset to nil at four seconds.
timeframe("giant", {0, "fee"}, 4, {1, "fi"}, {2, "fo"}, {3, "fum"})
-- sets the local 'width' variable to true immediately and back to nil in one second.
local width
timeframe(function(value) width = value end, 0, 1)
translateTable
- translateTable(directions, [languagecode])
- Given a table of directions (such as
speedWalkDir
), translates directions to another language for you. Right now, it can only translate it into the language of Mudlet's user interface - but let us know if you need more.
- Parameters
- directions:
- An indexed table of directions (eg.
{"sw", "w", "nw", "s"}
).
- languagecode:
- (optional) Language code (eg
ru_RU
orit_IT
) - by default,mudlet.translations.interfacelanguage
is used.
- Example
-- get the path from room 2 to room 5 and translate directions
if getPath(2, 5) then
speedWalkDir = translateTable(speedWalkDir)
print("Translated directions:")
display(speedWalkDir)
uninstallModule
- uninstallModule(name)
- Uninstalls a Mudlet module with the given name.
- See also: installModule(), Event: sysLuaUninstallModule
- Example
uninstallModule("myalias")
uninstallPackage
- uninstallPackage(name)
- Uninstalls a Mudlet package with the given name.
- See also: installPackage()
- Example
uninstallPackage("myalias")
unzipAsync
- unzipAsync(path, location)
- Unzips the zip file at path, extracting the contents to the location provided. Returns true if it is able to start unzipping, or nil+message if it cannot.
Raises the sysUnzipDone
event with the zip file location and location unzipped to as arguments if unzipping is successful, and sysUnzipError
with the same arguments if it is not.
Do not use the unzip()
function as it is synchronous and will impact Mudlet's performance (ie, freeze Mudlet while unzipping).
- Example
function handleUnzipEvents(event, ...)
local args = {...}
local zipName = args[1]
local unzipLocation = args[2]
if event == "sysUnzipDone" then
cecho(string.format("<green>Unzip successful! Unzipped %s to %s\n", zipName, unzipLocation))
elseif event == "sysUnzipError" then
cecho(string.format("<firebrick>Unzip failed! Tried to unzip %s to %s\n", zipName, unzipLocation))
end
end
if unzipSuccessHandler then killAnonymousEventHandler(unzipSuccessHandler) end
if unzipFailureHandler then killAnonymousEventHandler(unzipFailureHandler) end
unzipSuccessHandler = registerAnonymousEventHandler("sysUnzipDone", "handleUnzipEvents")
unzipFailureHandler = registerAnonymousEventHandler("sysUnzipError", "handleUnzipEvents")
--use the path to your zip file for this, not mine
local zipFileLocation = "/home/demonnic/Downloads/Junkyard_Orc.zip"
--directory to unzip to, it does not need to exist but you do need to be able to create it
local unzipLocation = "/home/demonnic/Downloads/Junkyard_Orcs"
unzipAsync(zipFileLocation, unzipLocation) -- this will work
unzipAsync(zipFileLocation .. "s", unzipLocation) --demonstrate error, will happen first because unzipping takes time
yajl.to_string
- yajl.to_string(data)
- Encodes a Lua table into JSON data and returns it as a string. This function is very efficient - if you need to encode into JSON, use this.
- Example
-- on IRE MUD games, you can send a GMCP request to request the skills in a particular skillset. Here's an example:
sendGMCP("Char.Skills.Get "..yajl.to_string{group = "combat"})
-- you can also use it to convert a Lua table into a string, so you can, for example, store it as room's userdata
local toserialize = yajl.to_string(continents)
setRoomUserData(1, "areaContinents", toserialize)
yajl.to_value
- yajl.to_value(data)
- Decodes JSON data (as a string) into a Lua table. This function is very efficient - if you need to dencode into JSON, use this.
- Example
-- given the serialization example above with yajl.to_string, you can deserialize room userdata back into a table
local tmp = getRoomUserData(1, "areaContinents")
if tmp == "" then return end
local continents = yajl.to_value(tmp)
display(continents)
