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.

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.

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).

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.

getCharacterName, PR #3952 open

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.

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 that may be replaced for more sophisticated requirements.

Note: Not available yet. See https://github.com/Mudlet/Mudlet/pull/3952

Example

lua send("cast 'glamor' " .. getCharacterName())

You get a warm feeling passing from your core to the tips of your hands, feet and other body parts.
A small twittering bird settles on your shoulder and starts to look adoringly at you.
A light brown faun gambles around you and then nuzzles your hand.
A tawny long-haired cat saunters over and start to rub itself against your ankles.
A small twittering bird settles on your shoulder and starts to look adoringly at you.
A light brown faun gambles around you and then nuzzles your hand.
A small twittering bird settles on your shoulder and starts to look adoringly at you.
A mangy dog trots up to you and proceeds to mark the bottom of your leggings.

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:

Predefined custom login texts
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:
function doLogin()
  if getCustomLoginTextId() ~= 1 then
    -- We need this particular option but it is not permitted for a script to change the setting, it can only check what it is
    echo("\nUnable to login - please select the 'connect {character name} {password}` custom login option in the profile preferences.\n")
  else
    tempTime(2.0, [[sendCustomLoginText()]], 1)
  end
end

sendCharacterName, PR #3952 open

sendCharacterName()

Sends the name entered into the "Character name" field on the Connection Preferences form directly to the game server. Returns true unless there is nothing set in that entry in which case a nil and an error message will be returned instead.

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 that may be replaced for more sophisticated requirements.

Note: Not available yet. See https://github.com/Mudlet/Mudlet/pull/3952

sendCharacterPassword, PR #3952 open

sendCharacterPassword()

Sends the password entered into the "Password" field on the Connection Preferences form directly to the game server. Returns true unless there is nothing set in that entry or it is too long after (or before) a connection was successfully made in which case a nil and an error message will be returned instead.

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, reproduced below, that may be replaced for more sophisticated requirements.

Note: Not available yet. See https://github.com/Mudlet/Mudlet/pull/3952

Example

-- The default function placed into LuaGlobal.lua to reproduce the previous behavior of the Mudlet application:
function doLogin()
  if getCharacterName() ~= "" then
    tempTime(2.0, [[sendCharacterName()]], 1)
    tempTime(3.0, [[sendCharacterPassword()]], 1)
  end
end

sendCustomLoginText, PR #3952 open

sendCustomLoginText()

Sends the custom login text (which does NOT depend on the user's choice of GUI language) selected in the preferences for this profile. The {password} (and {character name} if present) fields will be replaced with the values entered into the "Password" and "Character name" fields on the Connection Preferences form and then sent directly to the game server. Returns true unless there is nothing set in either of those entries (though only if required for the character name) or it is too long after (or before) a connection was successfully made or if the custom login feature is disabled, in which case a nil and an error message will be returned instead.

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.

ansi2decho PR# 5670 merge, PR5719 merged

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)

cecho PR #5669 merged, PR5719 merged, PR5751 merged

cecho([window], text): Echoes text that can be easily formatted with colour, italics, bold, strikethrough, and underline tags. You can also include unicode art in it - try some examples from 1lineart.; 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,¸")

cecho2ansi PR# 5672 merged

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

decho PR #5669 merged PR5719 merged PR5751 merged

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 italics, bold, <s>strikethrough</s>, <o>overline</o>, and underline tags.

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.
