UI Functions

ansi2decho

ansi2decho(text): Converts ANSI colour sequences in text to colour tags that can be processed by the decho() function. Bold, italics, underline not currently supported since decho doesn't support them.; See also: decho()

Parameters

text:

String that contains ANSI colour sequences that should be replaced.

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)

Note: Available in Mudlet 3.0 and later.

appendBuffer

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

Parameters

name:

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

Example

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

bg

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

Parameters

window:

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

colorName:

The name of the color to set the background to.

Example

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

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

calcFontSize

calcFontSize(fontSize): Used to calculate the number of pixels wide a 'W' character would be and the extreme top and bottom pixels that any character in the font would be on a mini console at fontSize. As the primary intended usage is for calculating the needed dimensions of a miniConsole, it doesn't accept a font argument as the miniConsoles currently only work with the default monospaced font for the sake of portability.; Returns two numbers, width/height; See Also: setMiniConsoleFontSize(), getMainWindowSize()

Parameters

fontSize:

The font size you are wanting to calculate pixel sizes for. Passed as an integer number.

Example

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

cecho

cecho(window, text): Echoes text that can be easily formatted with colour tags. You can also include unicode art in it - try some examples from 1lineart.; See also: decho(), hecho()

Parameters

window:

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

text:

The text to display, with color names inside angle brackets <>, ie <red>. If you'd like to use a background color, put it after a 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("myinfo", "<green>All of this text is green in the myinfo miniconsole.")

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

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

cecho([[

]])

cechoLink

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

cinsertText

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

Parameters

window:

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

text:

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

Example

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

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

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

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

clearUserWindow

clearUserWindow(name): Clears the window or miniconsole with the name given as argument.

Parameters

name:

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

Example

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

clearWindow

clearWindow([optional name]): This is (now) identical to clearUserWindow() which clears the label, miniconsole, or userwindow with the name given as argument (removes all text from it). If you don't give it a name, it will clear the main window.

Parameters

name:

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

Example

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

-- this can clear your whole main window - needs 2.0-test3+
clearWindow()

copy

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

Parameters

windowName (optional):

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

Example

-- This script copies the current line on the main screen to a window (miniconsole or userwindow) called 'chat' and gags the output on the main screen.
selectString(line, 1)
copy()
appendBuffer("chat")
replace("This line has been moved to the chat window!")

createBuffer

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

Parameters

name:

The name of the buffer to create.

Example

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

createButton

A similar function to createLabel() that is old and outdated - use createLabel() instead.

createConsole

createConsole(consoleName, fontSize, charsPerLine, numberOfLines, Xpos, Ypos): Makes a new miniconsole which can be sized based upon the width of a 'W' character and the extreme top and bottom positions any character of the font should use. The background will be black, and the text color white.

Parameters

consoleName:

The name of your new miniconsole. Passed as a string.

fontSize:

The font size to use for the miniconsole. Passed as an integer number.

charsPerLine:

How many characters wide to make the miniconsole. Passed as an integer number.

numberOfLines:

How many lines high to make the miniconsole. Passed as an integer number.

Xpos:

X position of miniconsole. Measured in pixels, with 0 being the very left. Passed as an integer number.

Ypos:

Y position of miniconsole. Measured in pixels, with 0 being the very top. Passed as an integer number.

Example

-- this will create a console with the name of "myConsoleWindow", font size 8, 80 characters wide, 
-- 20 lines high, at coordinates 300x,400y
createConsole("myConsoleWindow", 8, 80, 20, 200, 400)

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

createGauge

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

Parameters

name:

The name of the gauge. Must be unique, you can not have two or more gauges with the same name. Passed as a string.

width:

The width of the gauge, in pixels. Passed as an integer number.

height:

The height of the gauge, in pixels. Passed as an integer number.

Xpos:

X position of gauge. Measured in pixels, with 0 being the very left. Passed as an integer number.

Ypos:

Y position of gauge. Measured in pixels, with 0 being the very top. Passed as an integer number.

gaugeText:

Text to display on the gauge. Passed as a string, unless you do not wish to have any text, in which case you pass nil

r:

The red component of the gauge color. Passed as an integer number from 0 to 255

g:

The green component of the gauge color. Passed as an integer number from 0 to 255

b:

The blue component of the gauge color. Passed as an integer number from 0 to 255

colorName:

the name of color for the gauge. Passed as a string.

orientation:

the gauge orientation. Can be horizontal, vertical, goofy, or batty.

Example

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


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

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

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

createLabel

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

Parameters

name:

The name of the label. Must be unique, you can not have two or more labels with the same name. Passed as a string.

Xpos:

X position of the label. Measured in pixels, with 0 being the very left. Passed as an integer number.

Ypos:

Y position of the label. Measured in pixels, with 0 being the very top. Passed as an integer number.

width:

The width of the label, in pixels. Passed as an integer number.

height:

The height of the label, in pixels. Passed as an integer number.

fillBackground:

Whether or not to display the background. Passed as either 1 or 0. 1 will display the background color, 0 will not.

Example

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

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

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


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

createMiniConsole

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

Returns true or false.

Parameters

name:

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

x, y, width, height

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

Example

-- first, determine the size of your screen
local windowWidth, windowHeight = getMainWindowSize()

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

echo("sys","Hello world!\n")
cecho("sys", "<:OrangeRed>This is random spam with the same background\n")
cecho("sys", "<blue:OrangeRed>and this is with a blue foreground. ")
cecho("sys", "<bisque:BlueViolet>Lastly, this is with both a foreground and a background.\n")

decho

decho ([name of console,] text): Color changes can be made using the format <FR,FG,FB:BR,BG,BB> 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>. 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").

Parameters

text:

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

name of console

Optional name of the console to echo to. Defaults to main.

Example

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

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

dechoLink

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

Parameters

windowName:

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

text:

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

command:

lua code to do when the link is clicked.

hint:

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

true:

requires argument for the colouring to work.

Example

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

deleteLine

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

Note: you do not need to put anything between () - it just deletes the line it is used on.

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

Example

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

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

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

deselect

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

Parameters

name:

The name of the window to stop having anything selected in. This is an optional argument, if name is not provided the main window will have its selection cleared.

Example

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

echoLink

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

echoUserWindow

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

echoPopup

echoPopup([window], text, {commands}, {hints}, [current or default format]): 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.

Parameters

window:

Optional - the window to echo to - use either main or omit for the main window, or the miniconsoles name otherwise.

name:

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

{lua code}:

a table of lua code strings to do. ie, {[[send("hello")]], [[echo("hi!"]]}

{hints}:

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

current or default format:

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

Example

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

fg

fg([window, ]colorName): If used on a selection, sets the foreground color to colorName - otherwise, it will set the color of the next text-inserting calls (echo(), insertText, echoLink(), and others); See Also: bg(), setBgColor()

Parameters

window:

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

colorName:

The name of the color to set the foreground to - list of possible names:

Example

--This would change the color of the text on the current line to green
selectCurrentLine()
fg("green")
resetFormat()

--This will echo red, green, blue in their respective colors
fg("red")
echo("red ")
fg("green")
echo("green ")
fg("blue")
echo("blue ")
resetFormat()

-- example of working on a miniconsole
fg("my console", "red")
echo("my console", "red text")

getBgColor

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

getColorWildcard

getColorWildcard(ansi color number): This function, given an ANSI color number (list), will return all strings on the current line that match it.

Parameters

ansi color number:

A color number (list) to match.

Example

-- we can run this script on a line that has the players name coloured differently to easily capture it from 
-- anywhere on the line
local match = getColorWildcard(14)

if match then
  echo("\nFound "..match.."!")
else
  echo("\nDidn't find anyone.")
end

getColumnNumber

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

Parameters

window:

The minoconsole to operate on - optional. If you'd like it to work on the main window, don't specify anything.

Note: the window argument is available in Mudlet 3.0.

Example

HelloWorld = Geyser.MiniConsole:new({
  name="HelloWorld",
  x="70%", y="50%",
  width="30%", height="50%",
})

HelloWorld:echo("hello!\n")
HelloWorld:echo("hello!\n")
HelloWorld:echo("hello!\n")

moveCursor("HelloWorld", 3, getLastLineNumber("HelloWorld"))
-- should say 3, because we moved the cursor in the HellWorld window to the 3rd position in the line
print("getColumnNumber: "..tostring(getColumnNumber("HelloWorld")))

moveCursor("HelloWorld", 1, getLastLineNumber("HelloWorld"))
-- should say 3, because we moved the cursor in the HellWorld window to the 1st position in the line
print("getColumnNumber: "..tostring(getColumnNumber("HelloWorld")))

getCurrentLine

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

Example

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

getFgColor

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

Parameters

windowName:

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

Example

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

getLastLineNumber

getLastLineNumber(window): Returns the latest line's number in the main window or the miniconsole. This could be different from getLineNumber() if the cursor was moved around.

Parameters

window:

The window to use - either use main for the main window, or the miniconsoles name.

Example

-- get the latest line's # in the buffer
local latestline = getLastLineNumber("main")

getLineCount

getLineCount(): Gets the absolute amount of lines in the current console buffer

Parameters: None

Example

Need example

getLines

getLines(from_line_number, to_line_number): Returns a section of the content of the screen text buffer. Returns a Lua table with the content of the lines on a per line basis. The form value is result = {relative_linenumber = line}.

Absolute line numbers are used.

Parameters

from_line_number:

First line number

to_line_number:

End line number

Example

-- retrieve & echo the last line: 
echo(getLines(getLineNumber()-1, getLineNumber())[1])

-- find out which server and port you are connected to (as per Mudlet settings dialog):
local t = getLines(0, getLineNumber())

local server, port

for i = 1, #t do
  local s, p = t[i]:match("looking up the IP address of server:(.-):(%d+)")
  if s then server, port = s, p break end
end

display(server)
display(port)

getLineNumber

getLineNumber([window]): Returns the absolute line number of the current user cursor (the y position). The cursor by default is on the current line the triggers are processing - which you can move around with moveCursor() and moveCursorEnd(). This function can come in handy in combination when using with moveCursor() and getLines().

Parameters

window:

The miniconsole to operate on - optional. If you'd like it to work on the main window, don't specify anything.

Note: the window argument is available in Mudlet 3.0.

Example

-- use getLines() in conjuction with getLineNumber() to check if the previous line has a certain word
if getLines(getLineNumber()-1, getLineNumber())[1]:find("attacks") then echo("previous line had the word 'attacks' in it!\n") end

-- check how many lines you've got in your miniconsole after echoing some text.
-- Note the use of moveCursorEnd() to update getLineNumber()'s output
HelloWorld = Geyser.MiniConsole:new({
  name="HelloWorld",
  x="70%", y="50%",
  width="30%", height="50%",
})

print(getLineNumber("HelloWorld"))

HelloWorld:echo("hello!\n")
HelloWorld:echo("hello!\n")
HelloWorld:echo("hello!\n")

-- update the cursors position, as it seems to be necessary to do
moveCursorEnd("HelloWorld")
print(getLineNumber("HelloWorld"))

getMainConsoleWidth

getMainConsoleWidth(): Returns a single number; the width of the main console (MUD output) in pixels.

Parameters: None

Example

-- Save width of the main console to a variable for future use.
consoleWidth = getMainConsoleWidth()

getMousePosition

getMousePosition(): Returns the x and y coordinates of the mouse's position, relative to the Mudlet window itself.

Parameters: None

Note: Available in Mudlet 3.1+

Example

-- Retrieve x and y position of the mouse to determine where to create a new label, then use that position to create a new label
local x, y = getMousePosition()
createLabel("clickGeneratedLabel", x, y, 100, 100, 1)
-- if the label already exists, just move it
moveWindow("clickGeneratedLabel", x, y)
-- and make it easier to notice
setBackgroundColor("clickGeneratedLabel", 255, 204, 0, 200)

getMainWindowSize

getMainWindowSize(): Returns two numbers, the width and height in pixels.

Parameters: None

Example

--this will get the size of your main mudlet window and save them 
--into the variables mainHeight and mainWidth
mainWidth, mainHeight = getMainWindowSize()

getStopWatchTime

getStopWatchTime(watchID): Returns the time (milliseconds based) in form of 0.058 (= clock ran for 58 milliseconds before it was stopped). Please note that after the stopwatch is stopped, retrieving the time will not work - it's only valid while it is running.; See also: createStopWatch()

Returns a number

Parameters

watchID

The ID number of the watch.

Example

-- an example of showing the time left on the stopwatch
teststopwatch = teststopwatch or createStopWatch()
startStopWatch(teststopwatch)
echo("Time on stopwatch: "..getStopWatchTime(teststopwatch))
tempTimer(1, [[echo("Time on stopwatch: "..getStopWatchTime(teststopwatch))]])
tempTimer(2, [[echo("Time on stopwatch: "..getStopWatchTime(teststopwatch))]])
stopStopWatch(teststopwatch)

handleWindowResizeEvent

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

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

Parameters: None

Example

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

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

hasFocus

hasFocus(): Returns true or false depending if Mudlet's main window is currently in focus (ie, the user isn't focused on another window, like a browser).

Parameters: None

Example

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

hecho

hecho(window, text): Echoes text that can be easily formatted with colour tags in the hexadecimal format.; See Also: decho(), cecho()

Parameters

window:

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

text:

The text to display, with color changes made within the string using the format |cFRFGFB,BRBGBB where FR is the foreground red value, FG is the foreground green value, FB is the foreground blue value, BR is the background red value, etc., BRBGBB is optional. |r can be used within the string to reset the colors to default.

Example

hecho("|ca00040black!")

hechoLink

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

hideToolBar

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

Parameters

name:

name of the button group to display

Example

hideToolBar("my offensive buttons")

hideWindow

hideWindow(name): This function hides a mini console label. To show it again, use showWindow().

Parameters: None

Example

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

  print("created red window top-right")

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

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

miniconsoleTest()

insertLink

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

Parameters

text:

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

command:

lua code to do when the link is clicked.

hint:

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

window:

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

Example

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

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

insertPopup

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

Parameters

window:

Optional - the window to echo to - use either main or omit for the main window, or the miniconsoles name otherwise.

name:

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

{lua code}:

a table of lua code strings to do. ie, {[[send("hello")]], [[echo("hi!"]]}.

{hints}:

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

current or default format:

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

Example

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

insertText

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

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

ioprint

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

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

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

Parameters

text:

The information you want to display.
Example

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

isAnsiBgColor

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

Parameters

ansiBgColorCode:

A color code to test for, possible codes are:

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

Example

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

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

isAnsiFgColor

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

Parameters

ansiFgColorCode:

A color code to test for, possible codes are:

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

Example

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

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

lowerWindow

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

Parameters

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

Note: This command is present in the development code branch at GitHub repository and is to be included sometime after the release of 3.0.0.

Example

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

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

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

moveCursor

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

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

Parameters

windowName:

The window you are going to move the cursor in.

x:

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

y:

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

Example

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

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

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

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

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

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

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

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

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

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

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

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

moveCursorEnd

moveCursorEnd( windowName ): Moves the cursor to the end of the buffer. "main" is the name of the main window, otherwise use the name of your user window.; See Also: moveCursor()

Returns true or false

Parameters

windowName:

The name of your user window.

Example

Need example

moveGauge

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

Parameters

gaugeName:

The name of your gauge

newX:

The horizontal pixel location

newY:

The vertical pixel location

Example

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

moveWindow

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

Parameters

name:

The name of your winow

newX:

The horizontal pixel location

newY:

The vertical pixel location

openUserWindow

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

Parameters

name: name of your window, it must be unique across ALL profiles if more than one is open (for multi-playing).
dontrestore: optional argument, if false is provided then the window won't be restored to its last known position.

Note: Since Mudlet 3.2 Mudlet will automatically remember the windows last position and the dontrestore argument is available as well.

Examples

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

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

paste

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

Parameters

windowName:

The name of your window

prefix

prefix(text): Prefixes text at the beginning of the current line when used in a trigger.

Parameters

text:

The information you want to prefix
Example

-- Prefix the hours, minutes and seconds onto our prompt even though Mudlet has a button for that
prefix(os.date("%H:%M:%S "))

print

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

Parameters

text:

The information you want to display.
Example

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

print

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

Parameters

text:

The information you want to display.
Example

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

raiseWindow

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

Parameters

labelName: the name of the label/console you wish to bring to the top of the rest.

Note: This command is present in the development code branch at GitHub repository and is to be included sometime after the release of 3.0.0.

Example

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

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

raiseWindow("blueLabel")                          --raises blueLabel back at the top, above redLabel

replace

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

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

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

Parameters

windowName: optional name of window (a miniconsole)
with: the new text to display.
keepcolor: available in 3.0, setting this to true will keep the existing colors.

Example

-- replace word "troll" with "cute trolly"
selectString("troll",1)
replace("cute trolly")

-- replace the whole line
selectCurrentLine()
replace("Out with the old, in with the new!")

replaceAll

replaceAll( what, with ): Replaces all occurrences of what in the current line with with.

Parameters

what: the text to replace
with: the new text to have in place

Examples

-- replace all occurrences of the word "south" in the line with "north"
replaceAll("south", "north")

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

resizeWindow

resizeWindow(name,width,height): Resizes a mini console or label; See also: createMiniConsole(), createLabel(), handleWindowResizeEvent(), resizeWindow(), setBorderTop()

selectCaptureGroup

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

Example: Perl Reqular expression e.g. "you have (\d+) Euro".

--If you want to color the amount of money you have green you do: 

selectCaptureGroup(1)
setFgColor(0,255,0)

selectSection

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

Example

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

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

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

selectString

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

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

Parameters

windowName:

Optional parameter to set the window in which to select text.

text:

The text to select. It is matched as a substring match (so the text anywhere within the line will get selected).

number_of_match:

The occurrence of text on the line that you'd like to select. For example, if the line was "Bob and Bob", 1 would select the first Bob, and 2 would select the second Bob.

Returns position in line or -1 on error (text not found in line)

Note: To prevent working on random text if your selection didn't actually select anything, check the -1 return code before doing changes:

if selectString( "big monster", 1 ) > -1 then fg("red") end

setBgColor

setBgColor([windowName], r,g,b ): Sets the current text background color in the main window unless windowName parameter given. If you have selected text prior to this call, the selection will be highlighted otherwise the current text background color will be changed. If you set a foreground or background color, the color will be used until you call resetFormat() on all further print commands.

setBold

setBold(windowName, boolean): Sets the current text font to bold (true) or non-bold (false) mode. If the windowName parameters omitted, the main screen will be used. If you've got text currently selected in the Mudlet buffer, then the selection will be bolded. Any text you add after with echo() or insertText() will be bolded until you use resetFormat().

windowName:

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

boolean:

A true or false that enables or disables bolding of text

Example

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

setFgColor

setFgColor([windowName],r, g, b): Sets the current text foreground color in the main window unless windowName parameter given.

windowName:

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

r:

The red component of the gauge color. Passed as an integer number from 0 to 255

g:

The green component of the gauge color. Passed as an integer number from 0 to 255

b:

The blue component of the gauge color. Passed as an integer number from 0 to 255

Example

--highlights the first occurrence of the string "Tom" in the current line with a red foreground color.
selectString( "Tom", 1 )
setFgColor( 255,0,0 )

setGauge

setGauge(gaugeName, currentValue, maxValue, gaugeText): Use this function when you want to change the gauges look according to your values. Typical usage would be in a prompt with your current health or whatever value, and throw in some variables instead of the numbers.

Example

-- create a gauge
createGauge("healthBar", 300, 20, 30, 300, nil, "green")

--Change the looks of the gauge named healthBar and make it 
--fill to half of its capacity. The height is always remembered.
setGauge("healthBar", 200, 400)

--If you wish to change the text on your gauge, you’d do the following:
setGauge("healthBar", 200, 400, "some text")

setGaugeStyleSheet

setGaugeStyleSheet(gaugeName, css, cssback, csstext): Sets the CSS stylesheets on a gauge - one on the front (the part that resizes accoding to the values on the gauge) and one in the back.

Example

setGaugeStyleSheet("hp_bar", [[background-color: QLinearGradient( x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #f04141, stop: 0.1 #ef2929, stop: 0.49 #cc0000, stop: 0.5 #a40000, stop: 1 #cc0000);
border-top: 1px black solid;
border-left: 1px black solid;
border-bottom: 1px black solid;
border-radius: 7;
padding: 3px;]],
[[background-color: QLinearGradient( x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #bd3333, stop: 0.1 #bd2020, stop: 0.49 #990000, stop: 0.5 #700000, stop: 1 #990000);
border-width: 1px;
border-color: black;
border-style: solid;
border-radius: 7;
padding: 3px;]])

setGaugeText

setGaugeText(gaugename, css, ccstext ): Set the formatting of the text used inside the inserted gaugename.

Example

setGaugeText("healthBar", [[<p style="font-weight:bold;color:#C9C9C9;letter-spacing:1pt;word-spacing:2pt;font-size:12px;text-align:center;font-family:arial black, sans-serif;">]]..MY_NUMERIC_VARIABLE_HERE..[[</p>]])

setHexBgColor

setHexFgColor([windowName], hexColorString): Sets the current text nackground color in the main window unless windowName parameter given. This function allows to specify the color as a 6 character hexadecimal string.

windowName:

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

hexColorString

6 character long hexadecimal string to set the color to. The first two characters 00-FF represent the red part of the color, the next two the green and the last two characters stand for the blue part of the color

setHexFgColor

setHexFgColor([windowName], hexColorString): Sets the current text foreground color in the main window unless windowName parameter given. This function allows to specify the color as a 6 character hexadecimal string.

windowName:

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

hexColorString

6 character long hexadecimal string to set the color to. The first two characters 00-FF represent the red part of the color, the next two the green and the last two characters stand for the blue part of the color

setItalics

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

setMiniConsoleFontSize

setMiniConsoleFontSize(name, fontSize)

Sets the font size of the mini console. see also: createMiniConsole(), createLabel()

setTextFormat

setTextFormat(windowName, r1, g1, b1, r2, g2, b2, bold, underline, italics): Sets current text format of window windowName: foreground color(r1,g1,b1), background color(r2,g2,b2), bold(1/0), underline(1/0), italics(1/0) A more convenient way to control the text format in a mini console is to use setFgColor( windowName, r,g,b ), setBold( windowName, true ), setItalics( windowName, true ), setUnderline( windowName, true ) etc. → createMiniConsole, setBold, setBgColor, setFgColor, setItalics, setUnderline

Example

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

setUnderline

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

setWindowWrap

setWindowWrap(windowName, wrapAt): sets at what position in the line the console or miniconsole will start word wrap

showCaptureGroups

showCaptureGroups(): Lua debug function that highlights in random coolors all capture groups in your trigger regex on the screen. This is very handy if you make complex regex and want to see what really matches in the text. This function is defined in LuaGlobal.lua.

Example: Make a trigger with the regex (\w+) and call this function in a trigger. All words in the text will be highlighted in random colors.

showMultimatches

showMultimatches(): Lua helper function to show you what the table multimatches[n][m] contains. This is very useful when debugging multiline triggers - just doing showMultimatches() in your script will make it give the info.

showWindow

showWindow(name): Makes a hidden window (label or miniconsole) be shown again.

suffix

suffix(text): Suffixes text at the end of the current line. This is similar to echo(), which also suffixes text at the end of the line, but different - echo() makes sure to do it on the last line in the buffer, while suffix does it on the line the cursor is currently on.

replaceWildcard

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

selectString(matches[2], 1)
replace("text")

Parameters

which:

Wildcard to replace.

replacement:

Text to replace the wildcard with.

Example

replaceWildcard(2, "hello") -- on a perl regex trigger of ^You wave (goodbye)\.$, it will make it seem like you waved hello

resetFormat

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

Parameters: None

Example

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

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

-- another example: just highlighting some words
for _, word in ipairs{"he", "she", "her", "their"} do
  if selectString(word, 1) ~= -1 then
    bg("blue")
  end
end
resetFormat()

selectCurrentLine

selectCurrentLine([windowName]): Selects the content of the current line that the cursor at. By default, the cursor is at the start of the current line that the triggers are processing, but you can move it with the moveCursor() function. Note: This selects the whole line, including the linebreak - so it has a subtle difference from the slightly slower selectString(line, 1) selection method.; See Also: selectString(), getCurrentLine()

Parameters

windowName:

Optional parameter to set the window in which to select text.

Example

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

setAppStyleSheet

setAppStyleSheet(stylesheet): Sets a stylesheet for the entire Mudlet application - allowing you to customise content outside of the main window (the profile tabs, the scrollbar, and so on).

Parameters

stylesheet:

The entire stylesheet you'd like to use.

References: See Qt Style Sheets Reference for the list of widgets you can style and CSS properties you can apply on them.; See also QDarkStyleSheet, a rather extensive stylesheet that shows you all the different configuration options you could apply, available as an mpackage here.

Note: Available since Mudlet 3.0.

setBackgroundColor

setBackgroundColor(labelName, red, green, blue, transparency): Sets rgb color values and the transparency for the given window. Colors are from 0 to 255 (0 being black), and transparency is from 0 to 255 (0 being completely transparent).

Note: Transparency only works on labels, not miniConsoles for efficiency reasons.

Parameters

labelName:

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

red:

Amount of red to use, from 0 (none) to 255 (full).

green:

Amount of green to use, from 0 (none) to 255 (full).

blue:

Amount of red to use, from 0 (none) to 255 (full).

transparency:

Amount of transparency to use, from 0 (fully transparent) to 255 (fully opaque).

Example

-- make a red label that's somewhat transparent
setBackgroundColor("some label",255,0,0,200)

setBackgroundImage

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

Note you can also load images via setLabelStyleSheet().

Parameters

labelName:

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

imageLocation:

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

Example

-- give the top border a nice look
setBackgroundImage("top bar", [[/home/vadi/Games/Mudlet/games/top_bar.png]])

setBorderBottom

setBorderBottom(size): Sets the size of the bottom border of the main window in pixels. A border means that the MUD text won't go on it, so this gives you room to place your graphical elements there.; See Also: setBorderColor()

Parameters

size:

Height of the border in pixels - with 0 indicating no border.

Example

setBorderLeft(100)

setBorderColor

setBorderColor(r,g,b): Sets the color of the main windows border that you can create either with setBorderTop(), setBorderBottom(), setBorderLeft(), setBorderRight(), or via the main window settings.; See Also: setBorderTop(), setBorderBottom(), setBorderLeft(), setBorderRight()

Parameters

r:

Amount of red to use, from 0 to 255.

g:

Amount of green to use, from 0 to 255.

b:

Amount of blue to use, from 0 to 255.

setBorderColor(0, 0, 255)

-- or red, using a name
setBorderColor( unpack(color_table.red) )

setBorderLeft

setBorderLeft(size): Sets the size of the left border of the main window in pixels. A border means that the MUD text won't go on it, so this gives you room to place your graphical elements there.; See Also: setBorderColor()

Parameters

size:

Width of the border in pixels - with 0 indicating no border.

Example

setBorderRight(100)

setBorderTop

setBorderTop(size): Sets the size of the top border of the main window in pixels. A border means that the MUD text won't go on it, so this gives you room to place your graphical elements there.; See Also: setBorderColor()

setLink

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

Parameters

window:

optional: a miniconsole or a userwindow in which to select the text in.

command:

command to do when the text is clicked.

tooltip:

tooltip to show when the mouse is over the text - explaining what would clicking do.

Example

-- you can clickify a lot of things to save yourself some time - for example, you can change
--  the line where you receive a message to be clickable to read it!
-- prel regex trigger:
-- ^You just received message #(\w+) from \w+\.$
-- script:
selectString(matches[2], 1)
setUnderline(true) setLink([[send("msg read ]]..matches[2]..[[")]], "Read #"..matches[2])
resetFormat()

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

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

-- This creates a label with a single image, that can be resized (such as during a
-- sysWindowResizeEvent). To use this example, please supply your own image.
createLabel("test9", 215, 353, 100, 100, 0)
setLabelStyleSheet("test9", [[
  border-image: url(C:/Users/Administrator/.config/mudlet/profiles/Midkemia Online/Vyzor/MkO_logo.png);
  ]])

setMainWindowSize

setMainWindowSize(mainWidth, mainHeight): Adjusts the size of your main Mudlet window

Parameters

mainWidth:

The new width of the main window in pixels.

mainHeight:

The new height of the main window in pixels.

Example

--this will resize your main Mudlet window 
setMainWindowSize(1024, 768)

setPopup

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

Parameters

name:

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

{lua code}:

a table of lua code strings to do. ie, {[[send("hello")]], [[echo("hi!"]]}

{hints}:

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

Example

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

selectString("Hello", 1)
setPopup("main", {[[send("bye")]], [[echo("hi!")]]}, {"left-click or right-click and do first item to send bye", "click to echo hi"})

setStrikeOut

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

windowName:

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

boolean:

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

Example

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

showToolBar

showToolBar(name): Makes a toolbar (a button group) appear on the screen.

Parameters

name:

name of the button group to display

Example

showToolBar("my offensive buttons")

wrapLine

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

selectString(line,1)
replace("")

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