[solved] AutoCloseBraces.lua for SciTE

10 posts in this topic

#1 ·  Posted (edited)

Moin,

I want to add a ''AutoCloseBraces.lua" to - who'll guess it - autoclose braces/brackets and qoutes.

I've added the filename to the filelist in SciTEStartup.lua and copied it into the SciTE\LUA directory.

But it doesn't work.

Here's the code

function OnChar(charAdded)
 -- trace(charAdded)
     local toClose = { ['('] = ')', ['{'] = '}', ['['] = ']', ['"'] = '"', ["'"] = "'" }
 
     if toClose[charAdded] ~= nil then
         local pos = editor.CurrentPos
         editor:ReplaceSel(toClose[charAdded])
         editor:SetSel(pos, pos)
     end
     return false   -- Let next handler to process event
 -- return true  -- Don't let next handler to process event
 end
 -- http://osdir.com/ml/lib.scintilla.devel/2005-01/msg00046.html

Could anybody give me a tip how to realize this, please ?

OK, I got it working !

if somebody else is interested how to get it working, then add the following line to SciTEStartup.lua

LoadLuaFile("AutoCloseBraces.lua")

Now the SciTEStartup.lua should look like this

--------------------------------------------------------------------------------
  -- SciTE startup script.
  --------------------------------------------------------------------------------
  
  -- A table listing all loaded files.
  LoadLuaFileList = { }
  
  --------------------------------------------------------------------------------
  -- LoadLuaFile(file, directory)
  --
  -- Helper function for easily loading Lua files.
  --
  -- Parameters:
  --    file - The name of a Lua file to load.
  --    directory - If specified, file is looked for in that directory.  By default,
  --         this directory is $(SciTEDefaultHome)\Lua.
  --------------------------------------------------------------------------------
  function LoadLuaFile(file, directory)
      if directory == nil then
          directory = props["SciteDefaultHome"] .. "\\Lua\\"
      end
      table.insert(LoadLuaFileList, directory .. file)
      dofile(directory .. file)
  end   -- LoadLuaFile()
  
  -- Load all the Lua files.
  LoadLuaFile("Class.lua")  -- Always load first.
  LoadLuaFile("Common.lua") -- Always load second.
  LoadLuaFile("AutoItPixmap.lua")
  LoadLuaFile("AutoHScroll.lua")
  LoadLuaFile("AutoItAutoComplete.lua")
  LoadLuaFile("LoadSession.lua")
  LoadLuaFile("AutoItIndentFix.lua")
  LoadLuaFile("EdgeMode.lua")
  LoadLuaFile("SmartAutoCompleteHide.lua")
  LoadLuaFile("Tools.lua")
  LoadLuaFile("AutoItTools.lua")
  LoadLuaFile("AutoItGotoDefinition.lua")
  LoadLuaFile("AutoCloseBraces.lua")    -- Our Lua file
  
  -- Start up the events (Calls onstartup()).
  EventClass:BeginEvents()

At next copy the 'AutoCloseBraces.lua' into SciTE\LUA\

AutoCloseBraces = EventClass:new(Common)
  --------------------------------------------------------------------------------
  -- OnChar(charAdded)
  --
  -- AutoComplete Braces and Qoutes.
  --
  -- Parameters:
  --    charAdded - The character typed.
  --------------------------------------------------------------------------------
  
  function AutoCloseBraces:OnChar(charAdded)
  --    trace(charAdded)
      local toClose = { ['('] = ')', ['{'] = '}', ['['] = ']', ['"'] = '"', ["'"] = "'" }
  
      if toClose[charAdded] ~= nil then
          local pos = editor.CurrentPos
          editor:ReplaceSel(toClose[charAdded])
          editor:SetSel(pos, pos)
      end
      return false  -- Let next handler to process event
  --    return true  -- Don't let next handler to process event
  end

that's all, restart SciTE and now {, [, (, ' and " will be automtically closed and the cursor is set between.

Have Fun with this nice feature ... :)

What Happens when I need this?:

'"'
Just type ' at next " and then Entf/Del ... :)

It's quicker than all other variants, however, for me it is.

You could improve that type of behaviour by testing what type the lexer identified and not add the closing character when you are inside a String or Comment for example. This is an example used in the LUA functions:

ls = editor.StyleAt[editor.CurrentPos]
if ls ~= SCE_AU3_COMMENTBLOCK and ls ~= SCE_AU3_COMMENT and ls ~= SCE_AU3_STRING and ls ~= SCE_AU3_PREPROCESSOR and ls ~= SCE_AU3_SPECIAL then

:)

:party:

I'm new to Lua, more precisely I took today the first time a deeper look into Lua and I don't really understand the syntax.

Maybe if I have more time I can try to learn Lua ... (C++ is in the moment in my brain and sucks it empty :lmao: )

[wish]

Oooor ... :) , maybe if you are bored for a while, you could add this to SciTE's menu as an optional feature ... :)

This will disable the feature in strings ...

--------------------------------------------------------------------------------
-- OnChar(charAdded)
--
-- AutoComplete Braces and Qoutes.
--
-- Parameters:
--  charAdded - The character typed.
--------------------------------------------------------------------------------

function AutoCloseBraces:OnChar(charAdded)
--  trace(charAdded)
    local toClose = { ['('] = ')', ['{'] = '}', ['['] = ']', ['"'] = '"', ["'"] = "'" }
    local ls = editor.StyleAt[editor.CurrentPos]

    if ls ~= SCE_AU3_STRING then
        if toClose[charAdded] ~= nil then
            local pos = editor.CurrentPos
            editor:ReplaceSel(toClose[charAdded])
            editor:SetSel(pos, pos)
        end
    end
    return false    -- Let next handler to process event
--  return true  -- Don't let next handler to process event
end

I really like this feature; however, maybe a suggestion:

While inside of the ", ', (, [, groups, pressing enter would remove you from that. Having to constantly press the 'right' arrow key is quite frustrating.

So, when, for example, we are typing like this:

GuiCtrlCreateButton("this is a test"

If we were to press 'enter' after typing 'test', it should move us right after the ", same applies if it's one of the other groups too, thus allowing quicker code insertion.

Thanks :)

Yours produces an error on startup.
