Useful Mudlet scripts and macro

This pages' purpose is to share useful scripts, triggers, and macros for the MUD client Mudlet

SendSequence(...)

A LUA function to repeat a series of memorized commands. Useful to go back to lobby from your home point or to macro together one of your daily routine

Code

Must be saved in your mudlet "Scripts" Profile

 function SendSequence(interval, ...)
   local offset = 0
   for i = 1, select('#', ...) do
     if type(select(i, ...)) == "number" then
       offset = offset + select(i, ...) - interval
     elseif type(select(i, ...)) == "table" then
       local tab = select(i, ...)
       offset = SendSequence(interval, offset + interval, unpack(tab))
     else
       tempTimer(offset, [[send("]] .. select(i, ...) .. [[", true)]])
       echo("delayed (" .. offset .. "): send(\"" .. select(i, ...) .. "\")\n")
       offset = offset + interval
     end
   end
   return offset
 end

Arguments

• interval: the default time to wait between each command, be careful as some commands make the server die more that others
• ...: a nested list of commands string to send to the server. numbers are interpreted as additional wait time

Exemple

Recall to Zephyr studies (where you turn in the behavior bounty) as a Quetzalcoatl dedicant:

 SendSequence(0.1, "recall", 3, "o", "b") -- recall takes a long time to process, so we wait 3s to let the server process it before moving on the map

Use some predefined Sequences:

 -- in your Scripts profile
 Sequences = {}
 Sequences.ZephyrStudies = {"recall", 3, "o", "b"}

 -- anywhere else:
 SendSequence(0.1, Sequences.ZephyrStudies)

Combine Sequences to reach the RSX crafting room from somewhere very far:

 -- in your Scripts profile
 Sequences = {}
 Sequences.ZephyrStudies = {"recall", 3, "o", "b"}
 Sequences.Zephyr = {Sequences.ZephyrStudies, "e", "u"}
 Sequences.RSX = {Sequences.Zephyr, "depart", "e", "e", "e", "e", "e", "e", "e", "e", "n", "n", "n", "n", "n", "e", "enter"}
 Sequences.RSXCraftingRoom = {Sequences.RSX, "d", "e"}

 -- anywhere else
 SendSequence(0.1, Sequences.RSXCraftingRoom)

Link preview trigger

A trigger turning image URLs into clickable links that will open a popup on the side of your screen when clicked with a preview

Trigger parameters

• line 1: (?i)(?:http(?:s?):\/\/)([\/.\w\s\-~]*)\.(jpg|gif|png|webp) with type "perl regex"
• leave everything else as default

Trigger script

 local link = matches[1]
 local explodedPath = Split( matches[2] .. "." .. matches[3], "/")
 local file = explodedPath[#explodedPath]
 
 downloadFile(getMudletHomeDir() .. "/Preview Images/" .. file, link)
 selectString(link,1)
 setUnderline(true) 
 setLink([[showImagePreview("]] .. file .. [[")]],"Show Image Preview")
 resetFormat()

Additional profile folder

navigate to the folder pointed to after typing "lua getMudletHomeDir()". Create a folder named "Preview Images" there

Code

Must be saved in your mudlet "Scripts" Profile

 function Split(str, delim, maxNb)
    -- Eliminate bad cases...
    if string.find(str, delim) == nil then
       return { str }
    end
    if maxNb == nil or maxNb < 1 then
       maxNb = 0    -- No limit
    end
    local result = {}
    local pat = "(.-)" .. delim .. "()"
    local nb = 0
    local lastPos
    for part, pos in string.gfind(str, pat) do
       nb = nb + 1
       result[nb] = part
       lastPos = pos
       if nb == maxNb then
          break
       end
    end
    -- Handle the last field
    if nb ~= maxNb then
       result[nb + 1] = string.sub(str, lastPos)
    end
    return result
 end

 function showImagePreview(file)
   local path = getMudletHomeDir() .. "/Preview Images/" .. file
   
   if GlobalCurrentPreview == path then
     createMiniConsole("imagePreview", 1200, 0, 0, 0)
     GlobalCurrentPreview = nil
   else
     local w, h = getImageSize(path)
     local actualWidth, availableHeight = getMainWindowSize()
     local availableWidth = actualWidth - 1100;
     
     if w > availableWidth then
       h = availableWidth / w * h
       w = availableWidth
     end
     
     if h > availableHeight then
       w = availableHeight / h * w
       h = availableHeight
     end
     
     createMiniConsole("imagePreview", actualWidth - w, 0, w, h)
     setBackgroundImage("imagePreview",path)
     GlobalCurrentPreview = path
   end
 end

Exemple

Now image links will be underlined, clicking them will bring up a view such as this:

e621 post preview trigger

Making the preview work on non-direct links is a bit harder, but e621 API is so easy to use that I might as well make one for it. **NOTE: this trigger is based upon, and relies on Link preview trigger to function**

Trigger parameters

• line 1: (?i)(?:http(?:s?):\/\/(?:e621|e926)\.net\/posts\/)(\d+) with type "perl regex"
• leave everything else as default

Trigger script

 local textToSelect = matches[1]
 local post = "https://e621.net/posts/" .. matches[2] .. ".json"
 
 local handlerId
 handlerId = registerAnonymousEventHandler("sysGetHttpDone", function(_, url, body)
   if url == post then
     killAnonymousEventHandler(handlerId)
     
     local json = yajl.to_value(body)
     local link = json.post.file.url
     
     local explodedPath = Split(link, "/")
     local file = explodedPath[#explodedPath]
     
     downloadFile(getMudletHomeDir() .. "/Preview Images/" .. file, link)
     selectString(textToSelect,1)
     setUnderline(true) 
     setLink(showImagePreview(" .. file .. "),"Show Image Preview")
     resetFormat()
   end
 end)
 
 getHTTP(post)
 tempTimer(5, killAnonymousEventHandler( .. handlerId .. ))
