Revision as of 16:06, 22 April 2024
This page is for the development of documentation for Lua API functions that are currently being worked on. Ideally the entries here can be created in the same format as will be eventually used in Lua Functions and its sub-sites.
Please use the Area_51/Template to add new entries in the sections below.
Links to other functions or parts in other sections (i.e. the main Wiki area) need to include the section details before the '#' character in the link identifier on the left side of the '|' divider between the identifier and the display text. e.g.
- [[Manual:Mapper_Functions#getCustomLines|getCustomLines()]]
rather than:
- [[#getCustomLines|getCustomLines()]]
which would refer to a link within the current (in this case Area 51) section. Note that this ought to be removed once the article is moved to the main wiki area!
The following headings reflect those present in the main Wiki area of the Lua API functions. It is suggested that new entries are added so as to maintain a sorted alphabetical order under the appropriate heading.
Basic Essential Functions
- These functions are generic functions used in normal scripting. These deal with mainly everyday things, like sending stuff and echoing to the screen.
Database Functions
- A collection of functions for helping deal with the database.
Date/Time Functions
- A collection of functions for handling date & time.
File System Functions
- A collection of functions for interacting with the file system.
Mapper Functions
- A collection of functions that manipulate the mapper and its related features.
updateMap
- updateMap()
- Updates the mapper display (redraws it). While longer necessary since Mudlet 4.18, you can use this this function to redraw the map after changing it via API.
- See also: centerview()
- Example
-- delete a some room
deleteRoom(500)
-- now make the map show that it's gone
updateMap()
mapSymbolFontInfo, PR #4038 closed
- mapSymbolFontInfo()
- See also: setupMapSymbolFont()
Note: pending, not yet available. See https://github.com/Mudlet/Mudlet/pull/4038
- returns
- either a table of information about the configuration of the font used for symbols in the (2D) map, the elements are:
- fontName - a string of the family name of the font specified
- onlyUseThisFont - a boolean indicating whether glyphs from just the fontName font are to be used or if there is not a glyph for the required grapheme (character) then a glyph from the most suitable different font will be substituted instead. Should this be true and the specified font does not have the required glyph then the replacement character (typically something like �) could be used instead. Note that this may not affect the use of Color Emoji glyphs that are automatically used in some OSes but that behavior does vary across the range of operating systems that Mudlet can be run on.
- scalingFactor - a floating point number between 0.50 and 2.00 which modifies the size of the symbols somewhat though the extremes are likely to be unsatisfactory because some of the particular symbols may be too small (and be less visible at smaller zoom levels) or too large (and be clipped by the edges of the room rectangle or circle).
- or nil and an error message on failure.
- As the symbol font details are stored in the (binary) map file rather than the profile then this function will not work until a map is loaded (or initialized, by activating a map window).
moveMapLabel, PR #6014 open
- moveMapLabel(areaID/Name, labeID/Text, coordX/deltaX, coordY/deltaY[, coordZ/deltaZ][, absoluteNotRelativeMove])
Re-positions a map label within an area in the 2D mapper, in a similar manner as the moveRoom() function does for rooms and their custom exit lines. When moving a label to given coordinates this is the position that the top-left corner of the label will be positioned at; since the space allocated to a particular room on the map is ± 0.5 around the integer value of its x and y coordinates this means for a label which has a size of 1.0 x 1,0 (w x h) to position it centrally in the space for a single room at the coordinates (x, y, z) it should be positioned at (x - 0.5, y + 0.5, z).
- See also: getMapLabels(), getMapLabel().
Note: pending, not yet available. See https://github.com/Mudlet/Mudlet/pull/6014
- Parameters
- areaID/Name:
- Area ID as number or AreaName as string containing the map label.
- labelID/Text:
- Label ID as number (which will be 0 or greater) or the LabelText on a text label. All labels will have a unique ID number but there may be more than one text labels with a non-empty text string; only the first matching one will be moved by this function and image labels also have no text and will match the empty string. with mo or AreaName as string containing the map label.
- coordX/deltaX:
- A floating point number for the absolute coordinate to use or the relative amount to move the label in "room coordinates" along the X-axis.
- coordY/deltaY:
- A floating point number for the absolute coordinate to use or the relative amount to move the label in "room coordinates" along the Y-axis.
- coordZ/deltaZ:
- (Optional) A floating point number for the absolute coordinate to use or the relative amount to move the label in "room coordinates" along the Z-axis, if omitted the label is not moved in the z-axis at all.
- absoluteNotRelativeMove:
- (Optional) a boolean value (defaults to false if omitted) as to whether to move the label to the absolute coordinates (true) or to move it the relative amount from its current location (false).
- Returns
- true on success or nil and an error message on failure, if successful it will also refresh the map display to show the result.
- Example
-- move the first label in the area with the ID number of 2, three spaces to the east and four spaces to the north
moveMapLabel(0, 2, 3.0, 4.0)
-- move the first label in the area with the ID number of 2, one space to the west, note the final boolean argument is unneeded
moveMapLabel(0, 2, -1.0, 0.0, false)
-- move the second label in the area with the ID number of 2, three and a half spaces to the west, and two south **of the center of the current level it is on in the map**:
moveRoom(1, 2, -3.5, -2.0, true)
-- move the second label in the area with the ID number of 2, up three levels
moveRoom(1, 2, 0.0, 0.0, 3.0)
-- move the second label in the "Test 1" area one space to the west, note the last two arguments are unneeded
moveRoom("Test 1", 1, -1.0, 0.0, 0.0, false)
-- move the (top-left corner of the first) label with the text "Home" in the area with ID number 5 to the **center of the whole map**, note the last two arguments are required in this case:
moveRoom(5, "Home", 0.0, 0.0, 0.0, true)
-- all of the above will return the 'true' boolean value assuming there are the indicated labels and areas
moveRoom, PR #6010 open
- moveRoom(roomID, coordX/deltaX, coordY/deltaY[, coordZ/deltaZ][, absoluteNotRelativeMove])
Re-positions a room within an area, in the same manner as the "move to" context menu item for one or more rooms in the 2D mapper. Like that method this will also shift the entirety of any custom exit lines defined for the room concerned. This contrasts with the behavior of the setRoomCoordinates() which only moves the starting point of such custom exit lines so that they still emerge from the room to which they belong but otherwise remain pointing to the original place.
- See also: setRoomCoordinates()
Note: pending, not yet available. See https://github.com/Mudlet/Mudlet/pull/6010
- Parameters
- roomID:
- Room ID number to move.
- coordX/deltaX:
- The absolute coordinate or the relative amount as a number to move the room in "room coordinates" along the X-axis.
- coordY/deltaY:
- The absolute coordinate or the relative amount as a number to move the room in "room coordinates" along the Y-axis.
- coordZ/deltaZ:
- (Optional) the absolute coordinate or the relative amount as a number to move the room in "room coordinates" along the Z-axis, if omitted the room is not moved in the z-axis at all.
- absoluteNotRelativeMove:
- (Optional) a boolean value (defaults to false if omitted) as to whether to move the room to the absolute coordinates (true) or the relative amount from its current location (false).
- Returns
- true on success or nil and an error message on failure, if successful it will also refresh the map display to show the result.
- Example
-- move the first room one space to the east and two spaces to the north
moveRoom(1, 1, 2)
-- move the first room one space to the west, note the final boolean argument is unneeded
moveRoom(1, -1, 0, false)
-- move the first room three spaces to the west, and two south **of the center of the current level it is on in the map**:
moveRoom(1, -3, -2, true)
-- move the second room up three levels
moveRoom(2, 0, 0, 3)
-- move the second room one space to the west, note the last two arguments are unneeded
moveRoom(2, -1, 0, 0, false)
-- move the second room to the **center of the whole map**, note the last two arguments are required in this case:
moveRoom(2, 0, 0, 0, true)
-- all of the above will return the 'true' boolean value assuming there are rooms with 1 and 2 as ID numbers
setupMapSymbolFont, PR #4038 closed
- setupMapSymbolFont(fontName[, onlyUseThisFont[, scalingFactor]])
- configures the font used for symbols in the (2D) map.
- See also: mapSymbolFontInfo()
Note: pending, not yet available. See https://github.com/Mudlet/Mudlet/pull/4038
- Parameters
- fontName one of:
- - a string that is the family name of the font to use;
- - the empty string "" to reset to the default {which is "Bitstream Vera Sans Mono"};
- - a Lua nil as a placeholder to not change this parameter but still allow a following one to be modified.
- onlyUseThisFont (optional) one of:
- - a Lua boolean true to require Mudlet to use graphemes (character) only from the selected font. Should a requested grapheme not be included in the selected font then the font replacement character (�) might be used instead; note that under some circumstances it is possible that the OS (or Mudlet) provided color Emoji Font may still be used but that cannot be guaranteed across all OS platforms that Mudlet might be run on;
- - a Lua boolean false to allow Mudlet to get a different glyph for a particular grapheme from the most suitable other font found in the system should there not be a glyph for it in the requested font. This is the default unless previously changed by this function or by the corresponding checkbox in the Profile Preferences dialogue for the profile concerned;
- - a Lua nil as a placeholder to not change this parameter but still allow the following one to be modified.
- scalingFactor (optional): a floating point value in the range 0.5 to 2.0 (default 1.0) that can be used to tweak the rectangular space that each different room symbol is scaled to fit inside; this might be useful should the range of characters used to make the room symbols be consistently under- or over-sized.
- Returns
- true on success
- nil and an error message on failure. As the symbol font details are stored in the (binary) map file rather than the profile then this function will not work until a map is loaded (or initialised, by activating a map window).
Miscellaneous Functions
- Miscellaneous functions.
compare, PR#7122 open
- 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)

createVideoPlayer, PR #6439
- createVideoPlayer([name of userwindow], x, y, width, height)
- Creates a miniconsole window for the video player to render in, the with the given dimensions. One can only create one video player at a time (currently), and it is not currently possible to have a label on or under the video player - otherwise, clicks won't register.
Note: A video player may also be created through use of the Mud Client Media Protocol, the playVideoFile() API command, or adding a Geyser.VideoPlayer object to ones user interface such as the example below.
Note: The Main Toolbar will show a Video button to hide/show the video player, which is located in a userwindow generated through createVideoPlayer, embedded in a user interface, or a dock-able widget (that can be floated free to anywhere on the Desktop, it can be resized and does not have to even reside on the same monitor should there be multiple screens in your system). Further clicks on the Video button will toggle between showing and hiding the map whether it was created using the createVideo function or as a dock-able widget.

loadVideoFile, PR #6439
- loadVideoFile(settings table) or loadVideoFile(name, [url])
- Loads video files from the Internet or the local file system to the "media" folder of the profile for later use with playVideoFile() and stopVideos(). Although files could be loaded or streamed directly at playing time from playVideoFile(), loadVideoFile() provides the advantage of loading files in advance.
Note: Video files consume drive space on your device. Consider using the streaming feature of playVideoFile() for large files.

getCustomLoginTextId, PR #3952 open
- getCustomLoginTextId()
Returns the Id number of the custom login text setting from the profile's preferences. Returns 0 if the option is disabled or a number greater than that for the item in the table; note it is possible if using an old saved profile in the future that the number might be higher than expected. As a design policy decision it is not permitted for a script to change the setting, this function is intended to allow a script or package to check that the setting is what it expects.
Introduced along with four other functions to enable game server log-in to be scripted with the simultaneous movement of that functionality from the Mudlet application core code to a predefined doLogin() function, a replacement for which is shown below.
Note: Not available yet. See https://github.com/Mudlet/Mudlet/pull/3952
Only one custom login text has been defined initially:
Id | Custom text | Introduced in Mudlet version |
---|---|---|
1 | "connect {character name} {password}" | TBD |
The addition of further texts would be subject to negotiation with the Mudlet Makers.
- Example
-- A replacement for the default function placed into LuaGlobal.lua to reproduce the previous behavior of the Mudlet application:

Mudlet Object Functions
- A collection of functions that manipulate Mudlet's scripting objects - triggers, aliases, and so forth.
ancestors, new in PR #6726
- ancestors(IDnumber, type)
- You can use this function to find out about all the ancestors of something.
- Returns a list as a table with the details of each successively distance ancestor (if any) of the given item; the details are in the form of a sub-table, within each containing specifically:
- its IDnumber as a number
- its name as a string
- whether it is active as a boolean
- its "node" (type) as a string, one of "item", "group" (folder) or "package" (module)
- Returns nil and an error message if either parameter is not valid
- Parameters
- IDnumber:
- The ID number of a single item, (which will be that returned by a temp* or perm* function to create such an item to identify the item).
- type:
- The type can be 'alias', 'button', 'trigger', 'timer', 'keybind', or 'script'.
- See also: isAncestorsActive(...), isActive(...)
- Example
-- To do
findItems, new in PR #6742
- findItems("name", "type"[, exact[, case sensitive]])
- You can use this function to determine the ID number or numbers of items of a particular type with a given name.
- Returns a list as a table with ids of each Mudlet item that matched or nil and an error message should an incorrect type string be given.
- Parameters
- name:
- The name (as a string) of the item, (which will be that returned by a temp* or perm* function to create such an item to identify the item).
- type:
- The type (as a string) can be 'alias', 'button', 'trigger', 'timer', 'keybind' , or 'script'.
- exact:
- (Optional) a boolean which if omitted or true specifies to match the given name against the whole of the names for items or only as a sub-string of them. As a side effect, if this is provided and is false and an empty string (i.e. "") is given as the first argument then the function will return the ID numbers of all items (both temporary and permanent) of the given type in existence at the time.
- case sensitive:
- (Optional) a boolean which if omitted or true specifies to match in a case-sensitive manner the given name against the names for items.
- Example
Given a profile with just the default packages installed (automatically) - including the echo one:
-- Should find just the package with the name:
lua findItems("echo", "alias")
{ 3 }
-- Should find both the package and the alias - as the latter contains "echo" with another character
lua findItems("echo", "alias", false)
{ 3, 4 }
-- Finds the ID numbers of all the aliases:
lua findItems("", "alias", false)
{ 1, 2, 3, 4, 5, 6, 7 }
-- Will still find the package with the name "echo" as we are not concerned with the casing now:
lua findItems("Echo", "alias", true, false)
{ 3 }
-- Won't find the package with the name "echo" now as we are concerned with the casing:
lua findItems("Echo", "alias", true, true)
{}
isActive, modified by PR #6726
- isActive(name/IDnumber, type[, checkAncestors])
- You can use this function to check if something, or somethings, are active.
- Returns the number of active things - and 0 if none are active. Beware that all numbers are true in Lua, including zero.
- Parameters
- name:
- The name (as a string) or, from Mudlet 4.17.0, the ID number of a single item, (which will be that returned by a temp* or perm* function to create such an item to identify the item).
- type:
- The type can be 'alias', 'button' (from Mudlet 4.10), 'trigger', 'timer', 'keybind' (from Mudlet 3.2), or 'script' (from Mudlet 3.17).
- checkAncestors:
- (Optional) If provided AND true (considered false if absent to reproduce behavior of previous versions of Mudlet) then this function will only count an item as active if it and all its parents (ancestors) are active (from Mudlet tbd).
- See also: exists(...), isAncestorsActive(...), ancestors(...)
- Example
echo("I have " .. isActive("my trigger", "trigger") .. " currently active trigger(s) called 'my trigger'!")
-- Can also be used to check if a specific item is enabled or not.
if isActive("spellname", "trigger") > 0 then
-- the spellname trigger is active
else
-- it is not active
end
Note: A positive ID number that does not exist will still return a 0 value, this is for constancy with the way the function behaves for a name that does not refer to any item either. If necessary the existence of an item should be confirmed with exists(...) first.
isAncestorsActive, new in PR #6726
- isAncestorsActive(IDnumber, "type")
- You can use this function to check if all the ancestors of something are active independent of whether it itself is, (for that use the two argument form of isActive(...)).
- Returns true if all (if any) of the ancestors of the item with the specified ID number and type are active, if there are no such parents then it will also returns true; otherwise returns false. In the event that an invalid type string or item number is provided returns nil and an error message.
- Parameters
- IDnumber:
- The ID number of a single item, (which will be that returned by a temp* or perm* function to create such an item to identify the item).
- type:
- The type can be 'alias', 'button', 'trigger', 'timer', 'keybind' or 'script' to define which item type is to be checked.
- See also: exists(...)
- Example
-- To do
Networking Functions
- A collection of functions for managing networking.
sendSocket revised in PR #7066 (Open)
- sendSocket(data)
- Sends given binary data as-is (or with some predefined special tokens converted to byte values) to the game. You can use this to implement support for a new telnet protocol, simultronics login etc.
- success = sendSocket("data")
- See also
- feedTelnet(), feedTriggers()
Note: Modified in Mudlet tbd to accept some tokens like "<NUL>" to include byte values that are not possible to insert with the standard Lua string escape "\###" form where ### is a three digit number between 000 and 255 inclusive or where the value is more easily provided via a mnemonic. For the table of the tokens that are known about, see the one in feedTelnet().
Note: The data (as bytes) once the tokens have been converted to their byte values is sent as is to the Game Server; any encoding to, say, a UTF-8 representation or to duplicate 0xff byte values so they are not considered to be Telnet <IAC> (Interpret As Command) bytes must be done to the data prior to calling this function.
- Parameters
- data:
- String containing the bytes to send to the Game Server possibly containing some tokens that are to be converted to bytes as well.
- Returns
- (Only since Mudlet tbd) Boolean true if the whole data string (after token replacement) was sent to the Server, false if that failed for any reason (including if the Server has not been connected or is now disconnected). nil and an error message for any other defect.
- Example
-- Tell the Server that we are now willing and able to process to process Ask the Server to a comment explaining what is going on, if there is multiple functionalities (or optional parameters) the examples should start simple and progress in complexity if needed!
-- the examples should be small, but self-contained so new users can copy & paste immediately without going diving in lots other function examples first.
-- comments up top should introduce / explain what it does
local something = function(exampleValue)
if something then
-- do something with something (assuming there is a meaningful return value)
end
-- maybe another example for the optional second case
local somethingElse = function(exampleValue, anotherValue)
-- lastly, include an example with error handling to give an idea of good practice
local ok, err = function()
if not ok then
debugc(f"Error: unable to do <particular thing> because {err}\n")
return
end
- Additional development notes
-- This function is still being written up.
feedTelnet added in PR #7066 (Open)==
- feedTelnet(data)
- Sends given binary data with some predefined special tokens converted to byte values, to the internal telnet engine, as if it had been received from the game. This is primarily to enable testing when new Telnet sub-options/protocols are being developed. The data has to be injected into the system nearer to the point where the Game Server's data starts out than feedTriggers() and unlike the latter the data is not subject to any encoding so as to match the current profile's setting (which normally happens with feedTriggers()). Furthermore - to prevent this function from putting the telnet engine into a state which could damage the processing of real game data it will refuse to work unless the Profile is completely disconnected from the game server.
- See also
- feedTriggers(), sendSocket()
Note: This is not really intended for end-user's but might be useful in some circumstances.
- Parameters
- data
- String containing the bytes to send to the internal telnet engine as if it had come from the Game Server, it can containing some tokens listed below that are to be converted to bytes as well.
- Returns
- Boolean true if the data string was sent to the internal telnet engine. nil and an error message otherwise, specifically the case when there is some traces of a connection or a complete connection to the socket that passes the data to and from the game server. Additionally, if the data is an empty string "" a second return value will be provided as an integer number representing a version for the table of tokens - which will be incremented each time a change is made to that table so that which tokens are valid can be determined. Note that unrecognised tokens should be passed through as is and not get replaced.

- Example
-- a comment explaining what is going on, if there is multiple functionalities (or optional parameters) the examples should start simple and progress in complexity if needed!
-- the examples should be small, but self-contained so new users can copy & paste immediately without going diving in lots other function examples first.
-- comments up top should introduce / explain what it does
local something = feedTelnet(exampleValue)
if something then
-- do something with something (assuming there is a meaningful return value)
end
-- maybe another example for the optional second case
local somethingElse = function(exampleValue, anotherValue)
-- lastly, include an example with error handling to give an idea of good practice
local ok, err = function()
if not ok then
debugc(f"Error: unable to do <particular thing> because {err}\n")

- Parameters
- [optional]triggerDelta:
- The line delta from the multiline trigger it is being called from. It is best to pass this in to ensure all lines are caught. If not given it will try to guess based on the number of patterns how many lines at most it might have to delete.

echoPopup, revised in PR #6946
- 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; if there is one extra hint then the first one will be used as a (maybe containing Qt rich-text markup) tool-tip for the text otherwise the remaining hints will be concatenated, one-per-line, as a tool-tip when the text is hovered over by the pointer.
- Parameters
- windowName:
- (optional) name of the window as a string to echo to. Use either main or omit for the main window, or the miniconsole's or user-window's name otherwise.
- text:
- the text string 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 right-click menu and as a tool-tip for the text. If the number is the same as that of the commands table then they all will be used for the right-click menu and listed (one per line) as a plain text tooltip; alternatively if there is one extra in number than the commands table the first will be used purely for the tool tip and the remainder will be used for the right-click menu. This additional entry may be formatted as Qt style "rich-text" (in the same manner as labels elsewhere in the GUI).
- If a particular position in the commands table is an empty string "" but there is something in the hints table then it will be listed in the right-click menu but as it does not do anything it will be shown greyed-out i.e. disabled and will not be clickable.
- If a particular position in both the commands and the hints table are empty strings "" then this item will show as a separator (usually as a horizontal-line) in the right-click menu and it will not be clickable/do anything.
- useCurrentFormatElseDefault:
- (optional) a boolean value for using either the current formatting options (color, underline, italic and other effects) if true or the link default (blue underline) if false, if omitted the default format is used.
- Example
-- Create some text as a clickable with a popup menu, a left click will ''send "sleep"'':
echoPopup("activities to do", {function() send "sleep" end, function() send "sit" end, function() send "stand" end}, {"sleep", "sit", "stand"})
-- alternatively, put commands as text (in [[ and ]] to use quotation marks inside)
echoPopup("activities to do", {[[send "sleep"]], [[send "sit"]], [[send "stand"]]}, {"sleep", "sit", "stand"})
-- one can also provide helpful information
-- todo: an example with rich-text in the tool-tips(s) - not complete yet!
echoPopup("Fancy popup", {[[echo("Doing command 1 (default one)")]], "", "", [[echo("Doing command 3")]], [[echo("Doing another command (number 4)"]], [[echo("Doing another command (number 5)"]])}, {"<p>This tooltip has HTML type tags in/around it, and it will get word-wrapped automatically to fit into a reasonable rectangle.</p><p><b>Plus</b> it can have those HTML like <i>effects</i> and be easily formatted into more than one paragraph and with <span style=\"color:cyan\">bits</span> in <span style=\"color:lime\">different</span> colors!</p><p>This example also demonstrates how to produce disabled menu (right-click) items, how to insert separators and how it now will handle multiple items with the same hint (prior to PR 6945 such duplicates will all run the command associated with the last one!) If the first command/function is an empty string then clicking on the text will have no effect, but hovering the mouse over the text will still produce the tooltip, this could be useful to display extra information about the text without doing anything by default.</p>", "Command 1 (default)", "", "Command 2 (disabled)", "Command 3", "Another command", "Another command"}, true)

insertPopup, revised in PR #6925
- insertPopup([windowName], text, {commands}, {hints}[{, tool-tips}][, 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; if a tool-tips table is not provided the same hints will also be listed one-per-line as a tool-tip but if a matching number of tool-tips are provided they will be concatenated to provide a tool-tip when the text is hovered over by the pointer - these tool-tips can be rich-text to produce information formatted with additional content in the same manner as labels.
- Parameters
- windowName:
- (optional) name of the window as a string to echo to. Use either main or omit for the main window, or the miniconsole's or user-window's name otherwise.
- text:
- the text string 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 right-click menu (and popup if no {tool-tips} table is provided). If a particular position in both the commands and hints table are both the empty string "" but there is something in the tool-tips table, no entry for that position will be made in the context menu but the tool-tip can still display something which can include images or text.
- {tool-tips}:
- (optional) a table of possibly rich-text strings which will be shown on the popup if provided.
- useCurrentFormatElseDefault:
- (optional) a boolean value for using either the current formatting options (color, underline, italic and other effects) if true or the link default (blue underline) if false, if omitted the default format is used.
Note: Mudlet will distinguish between the optional tool-tips and the flag to switch between the standard link and the current text format by examining the type of the argument, as such this pair of arguments can be in either order.
- Example
-- Create some text as a clickable with a popup menu, a left click will ''send "sleep"'':
insertPopup("activities to do", {function() send "sleep" end, function() send "sit" end, function() send "stand" end}, {"sleep", "sit", "stand"})

Playing Media
Send Client.Media.Play GMCP events to play sound or music files.
Required | Key | Value | Default | Purpose |
---|---|---|---|---|
Yes | "name" | <file name> |
| |

name
For example, to simply play the sound of a cow mooing already stored in the "media" folder:
Client.Media.Play {
"name": "cow.wav"
}
Or some lightning stored in a "weather" sub-folder under the "media" folder.
Client.Media.Play {
"name": "weather/lightning.wav"
}
The "name" parameter may be used for stopping media with the Client.Media.Stop GMCP event.
url
If you maintain your sound files on the Internet and don't set a default URL with Client.Media.Default, or preload them with Client.Media.Load, include the "url" parameter:
Client.Media.Play {
"name": "cow.wav",
"url": "https://www.example.com/sounds/"
}
type: sound
Media files default to a "type" of "sound" when the "type" parameter is not specified, such as in the example above. It is good practice to specify the "type" parameter to best keep media organized within your implementation:
Client.Media.Play {
"name": "cow.wav",
"type": "sound"
}
The "type" parameter may be used for stopping matching media with the Client.Media.Stop GMCP event.
tag
To play the sound of a sword swooshing and categorized as "combat":
Client.Media.Play {
"name": "sword1.wav",
"type": "sound",
"tag": "combat"
}
The "tag" parameter may be used for stopping matching media with the Client.Media.Stop GMCP event.
type: music
Add background music to your environment through use of the "music" value set upon the "type" parameter:
Client.Media.Play {
"name": "river.wav",
"type": "music",
"tag": "environment"
}
The "type" parameter may be used for stopping matching media with the Client.Media.Stop GMCP event.
volume: 1 to 100
As the character draws nearer to or farther from the environmental feature, consider adjusting the "volume" parameter. Example values, followed by syntax examples:
- Maximum: 100 (recommended to use rarely)
- High: 75
- Default: 50
- Low: 25
- Minimum: 1 (recommended to use rarely)
Client.Media.Play {
"name": "river.wav",
"type": "music",
"tag": "environment",
"volume": 75
}
Although using the integer type is recommended, Mudlet parses "volume" values of type string ("75") into integers (75) as needed.
fadein
Increase volume from the start of the media [start position, volume one] to the number in milliseconds specified with the "fadein" parameter [position start + milliseconds, volume specified with the "volume" parameter]. Example values, followed by syntax examples:
- 1000 milliseconds (1 second)
- 60000 milliseconds (1 minute)
- 0 milliseconds (no fade in)
Client.Media.Play {
"name": "monty_python.mp3",
"type": "music",
"volume": 100,
"fadein": 1000
}
+---------------------------+-----------------------+ | Fade in 1000 milliseconds | Normal | +---------------------------+-----------------------+ Volume 1|........::::::::::iiiiiiiii%%%%%%%%%%%%%%%%%%%%%%%%|Volume 100 +---------------------------+-----------------------+
Although using the integer type is recommended, Mudlet parses "fadein" values of type string ("1000") into integers (1000) as needed.
fadeout
Decrease volume from a position in milliseconds subtracted from the duration of the media [position duration - milliseconds, volume specified with the "volume" parameter] to the end of the media [position duration, volume one]. Example values, followed by syntax examples:
- 1000 milliseconds (1 second)
- 60000 milliseconds (1 minute)
- 0 milliseconds (no fade out)
Client.Media.Play {
"name": "the_matrix.mp3",
"type": "music",
"volume": 50,
"fadeout": 333
}
+-----------------------+---------------------------+ | Normal | Fade out 333 milliseconds | +-----------------------+---------------------------+ Volume 50|%%%%%%%%%%%%%%%%%%%%%%%%iiiiiiiii::::::::::........|Volume 1 +-----------------------+---------------------------+
Although using the integer type is recommended, Mudlet parses "fadeout" values of type string ("333") into integers (333) as needed.
start
Start playing a media track at the number of milliseconds specified. Example values, followed by syntax examples:
- 1000 milliseconds (1 second)
- 60000 milliseconds (1 minute)
- 0 milliseconds (start from beginning)
Client.Media.Play {
"name": "mudlet_beatboxing.mp3",
"type": "music",
"volume": 75,
"start": 1000
}
Although using the integer type is recommended, Mudlet parses "start" values of type string ("100") into integers (100) as needed.
finish
Finish playing a media track at the number of milliseconds specified. Example values, followed by syntax examples:
- 1000 milliseconds (1 second)
- 60000 milliseconds (1 minute)
- 0 milliseconds (start from beginning)
Client.Media.Play {
"name": "mudlet_beatboxing.mp3",
"type": "music",
"volume": 75,
"finish": 35000
}
Although using the integer type is recommended, Mudlet parses "finish" values of type string ("100") into integers (100) as needed.
loops: -1, 1 or more
The "loops" parameter controls how many times the sound repeats and defaults to 1 if not specified. A value of -1 will loop the file indefinitely.
Client.Media.Play {
"name": "clock/hour_bell.wav",
"type": "sound",
"loops": 3
}
Client.Media.Play {
"name": "underdark.mp3",
"type": "music",
"tag": "environment",
"loops": -1
}
Although using the integer type is recommended, Mudlet parses "loops" values of type string ("-1") into integers (-1) as needed.
priority: 1 to 100
The "priority" parameter sets precedence for Client.Media.Play GMCP events that include a "priority" setting. The values for the "priority" parameter range between 1 and 100. Given that two Client.Media.Play GMCP events have the same priority, the media already playing will continue playing. In Mudlet, media without priority set is not included comparisons based on priority.
A common place to find priority implemented is with combat. In the following example, imagine a combat scenario where some sounds of sword thrusts were interrupted by a successful blocking maneuver.
Client.Media.Play {
"name": "sword1.wav",
"type": "sound",
"tag": "combat",
"loops": 3,
"priority": 60
}
Client.Media.Play {
"name": "block1.wav",
"type": "sound",
"tag": "combat",
"priority": 70
}
Although using the integer type is recommended, Mudlet parses "priority" values of type string ("25") into integers (25) as needed.
The "priority" parameter may be used for stopping matching media with the Client.Media.Stop GMCP event.
continue: true or false (for music)
Typically sent with the "type" of "music" is the parameter "continue", which presents the following values:
- true: continues music that is already playing if it is requested again through a new Client.Media.Play GMCP event
- false: restarts music that is already playing if it is requested again through a new Client.Media.Play GMCP event
Client.Media.Play {
"name": "city.mp3",
"type": "music",
"tag": "environment",
"continue": true
}
If the "continue" parameter is not specified, behavior will default to true for music.
Although using the boolean type is recommended, Mudlet parses "continue" values of type string ("true" and "false") into boolean (true and false) as needed, as not all game drivers support a boolean type.
key
The "key" parameter enables media categorization, similar to the "tag" parameter, however it adds a feature of uniqueness that halts media currently playing with the same key, replacing it with the media that arrived from a new Client.Media.Play GMCP event. This update will only occur if the "name" or "url" associated with the currently playing media does not match the new media, while the key is identical.
In the example below, consider that a player moves from a sewer area to a village. The "key" parameter is used to stop the previously playing sewer.mp3 and start playing village.mp3 within the second Client.Media.Play GMCP event.
Client.Media.Play {
"name": "sewer.mp3",
"type": "music",
"tag": "environment",
"loops": -1,
"continue": true,
"key": "area-music"
}
Client.Media.Play {
"name": "village.mp3",
"type": "music",
"tag": "environment",
"loops": -1,
"continue": true,
"key": "area-music"
}
The "key" parameter may be used for stopping matching media with the Client.Media.Stop GMCP event.
Note: Where music is bound to change, continue or stop as a player enters a new room, consider allowing for a slight pause of 1 heart beat or tick to send the Client.Media.Play or Client.Media.Stop GMCP events. This practice reduces the number of Client.Media.Play GMCP events sent when the player travels through several rooms quickly.
randomization
Wildcards * (asterisk) and ? (question mark) may be used within the name to randomize media file(s) selection.
Given that media files underdark.wav, underdark.mp3 and underdark_dark_elven_moshpit.mp3 were all present in the media/environment directory under the current game profile, the following Client.Media.Play GMCP event would randomly choose one of those files to play using the * wildcard.
Client.Media.Play {
"name": "underdark*",
"type": "music",
"tag": "environment",
"loops": -1,
"continue": false
}
If media files sword1.wav, sword2.wav and sword3.wav were all present in the media/combat directory under the current game profile, the following Client.Media.Play GMCP event would randomly choose one of those files to play per each loop using the ? wildcard.
Client.Media.Play {
"name": "combat/sword?.wav",
"type": "sound",
"tag": "combat",
"loops": 3
}

Supported Protocols
Mudlet supports CHARSET, NEW-ENVIRON, MNES, MTTS, GMCP, MSSP, MSP, ATCP, Aardwolfs 102, MSDP, and the MXP Protocol.
CHARSET, NEW-ENVIRON, MTTS, MXP, MSSP, MSP, GMCP and 102 are enabled by default, MSDP and MNES can be enabled in settings.
NEW-ENVIRON, PR #7058
To enhance the player experience through sharing more client-supported details, the Telnet New-Environ Option may be used to transfer client environment variables from Mudlet to game servers. Sharing supporting information on information such as encoding, terminal emulation, and accessibility options aims to improve initial player setup and increase the retention rate for new gaming community members.
NEW-ENVIRON in Mudlet
Mudlet supports two methods of information exchange via NEW-ENVIRON, the first via RFC 1572: Telnet New-Environ Option (on by default), and the second is MNES: Mud New-Environ Standard (off by default), which shares a standardized set of client information across multiple clients.
Client Environment Variable Updates
Mudlet provides a user-friendly interface for managing environmental variables through its Settings menu. For certain environmental variables, manual selections made in the Settings menus can dynamically notify servers that have expressed interest in the client's environmental variables through the negotiation of the NEW-ENVIRON option. For instance, when a Mudlet user updates the data encoding for a server profile by navigating to Settings, General, and choosing a specific data encoding from the drop-down menu, this information becomes available for transmission via both the RFC (default) and MNES (requires user enabling) options.
Available Client Environment Variables RFC 1572
Two types of variables are used per RFC 152, well-known variables defined with VAR (0) and for less common variables, USERVAR (3). Some information requires a user to OPT-IN to share it with the game. Some client variables updates may be reported ad-hoc with an INFO (2) message. If there is no value for a defined variable, a VAL (1) will be sent without a value following it.
Type | Variable | Example Values | Mudlet Default | OPT-IN | INFO | Purpose | Available |
---|---|---|---|---|---|---|---|
VAR | SYSTEMTYPE | CYGWIN, WIN32, MACOS, LINUX, HURD, FREEBSD, NETBSD, OPENBSD, BSD4, UNIX | Yes | Client runs within the listed operating system. | Future | ||

Negotiating NEW-ENVIRON
Negotiating the NEW-ENVIRON Telnet option empowers game servers to request one, multiple, or all client environment variables configured within Mudlet. The process unfolds with the game server sending a Telopt DO NEW-ENVIRON (39), prompting Mudlet to respond with a WILL NEW-ENVIRON (39). Subsequently, the game server can send SB NEW-ENVIRON (39) SEND to receive all available environment variables. Mudlet responds with SB NEW-ENVIRON (39) IS (0) < VAR (0) | USERVAR (3) > "<variable>" [VAL (1)] ["<value>"] [ .. [ VAR (0) | USERVAR (3) ] "<variable>" VAL (1) "<value>"] containing the list of environmental variables.
Once an environmental variable is transmitted to a server within the ongoing connection, Mudlet replies with SB NEW-ENVIRON (39) INFO (2) < VAR (0) | USERVAR (3) > "<variable>" [VAL (1)] ["<value>"] messages for select variables. Importantly, no reply from the server is required in this context. If there is a need to specify a particular list of requested environmental variables to Mudlet, the format SB NEW-ENVIRON (39) SEND < VAR (0) | USERVAR (3) > "<variable>" [ .. < VAR (0) | USERVAR (3) > "<variable>" ] can be employed.

The Mud New-Environment Standard is an alternative way to share client-supported details between Mudlet to game servers.
Activating MNES
If your game supports MNES, instruct users to toggle on the `Enable MNES` menu option on the General tab in Mudlet.
Mud New-Environ Standard Client Environment Variables MNES
MNES leverages VAR (0) to transfer up to five client environment variables. Some client variables updates may be reported ad-hoc with an INFO message. If there is no value for a defined variable, a VAL (1) will be sent without a value following it.
Type | Variable | Example Values | Mudlet Default | INFO | Purpose |
---|---|---|---|---|---|
VAR | CHARSET | UTF-8, ASCII | Yes | Encoding set in the client | |

Negotiating MNES
The primary differences between MNES and the out-of-the-box RFC 152 NEW-ENVIRON implementation is that MNES sends no more than 5 client environment variables ("IPADDRESS" will not be implemented in Mudlet), it uses a VAR (0) for the SEND (1), IS (0), and INFO (2) messages, and returns a multiple client variable response in multiple IS (0) messages.

MTTS, PR #7036
MUD servers frequently seek information about the capabilities of a MUD Client. Despite the availability of various methods, achieving consistency and reliability in this endeavor has proven challenging. The Mud Terminal Type Standard (MTTS) aims to alleviate these issues by introducing a transparent and straightforward standard for MUD Clients to communicate their terminal capabilities. This standard builds upon and formalizes RFC 1091, which outlines the Telnet Terminal-Type Option.
MTTS in Mudlet
By incorporating the Mud Terminal-Type Standard (MTTS), Mudlet will communicate with interested servers that it possesses the following capabilities:
- Support for ANSI Color Codes: The client supports all common ANSI color codes.
- UTF-8 Character Encoding: The client utilizes UTF-8 character encoding.
- Support for 256 Color Codes: Mudlet is equipped to handle all 256 color codes.
- OSC Color Palette: Mudlet acknowledges support for the OSC color palette.
- Screen Reader Support: Mudlet offers support for screen readers, with opt-in functionality (not advertised by default).
- Truecolor Codes: Mudlet supports truecolor codes using semicolon notation.
- Mud New Environment Standard (MNES) Support: The client adheres to the Mud New Environment Standard for information exchange.
- TLS Encryption: The client supports Transport Layer Security for data encryption.
Screen Reader Opt-In
Users can find on the Accessibility tab under the Settings menu a checkbox identified as "Advertise screen reader use via protocols supporting this notice" which when checked will notify interested game servers. This information may be used to optimize the gaming experience.
Available MTTS Information
Through a Telnet TERMINAL-TYPE Option negotiation, Mudlet transfers a bitvector to game servers, (i.e., 2349
) for processing. A bitvector, also known as a bitmap, is a data structure that represents a fixed-size sequence of binary digits or bits. In a bitvector, each bit corresponds to a specific position or index in the sequence, and its value can be either 0 or 1. The MTTS bitvector represents is a set of flags and boolean values, where each bit can represent the state of a particular boolean condition or flag. For example, if the third bit is set to 1
, it indicates that the client is using UTF-8 character encoding. A 0
indicator would indicate that UTF-8 was not supported.
Bit | Property | Meaning |
---|---|---|
1 | ANSI | Client supports all common ANSI color codes. |
2 | VT100 | Client supports all common VT100 codes. |
4 | UTF-8 | Client is using UTF-8 character encoding. |
8 | 256 COLORS | Client supports all 256 color codes. |
16 | MOUSE TRACKING | Client supports xterm mouse tracking. |
32 | OSC COLOR PALETTE | Client supports OSC and the OSC color palette. |
64 | SCREEN READER | Client is using a screen reader. |
128 | PROXY | Client is a proxy allowing different users to connect from the same IP address. |
256 | TRUECOLOR | Client supports truecolor codes using semicolon notation. |
512 | MNES | Client supports the Mud New Environment Standard for information exchange. |
1024 | MSLP | Client supports the Mud Server Link Protocol for clickable link handling. |
2048 | TLS | Client supports Transport Layer Security for data encryption. |
Negotiating MTTS
Per the MTTS guidance, game servers should initiate up to 4 TTYPE requests to complete the TTYPE cycling routine within a given connection. If the connection is reset, negotiate TTYPE again. Reference the MTTS website for more information.
Server | Mudlet |
