Scite Xml Autocompletion

wiki

This script enables Visual Studio-like XML autocompletion: ending tags are automatically added and attributes are automatically quoted. This works for XHTML and any XML files.

Copy the following code in your Lua startup script:

function OnChar(c)
	local nLexer = editor.Lexer
	if nLexer ~= 4 and nLexer ~= 5 then return false end

	-- tag completion
	if c == ">" then
		local pEnd = editor.CurrentPos - 1
		if pEnd < 1 then return false end
		local nStyle = editor.StyleAt[pEnd - 1]
		if nStyle > 8 then return false end
		local nLastChar = editor.CharAt[pEnd - 1]
		if nStyle == 6 and nLastChar ~= 34 then return false end
		if nStyle == 7 and nLastChar ~= 39 then return false end
		if nLastChar == 47 or nLastChar == 37 or nLastChar == 60 or nLastChar == 63 then return false end
		local pStart = pEnd
		repeat
			pStart = pStart - 1
			if (editor.CharAt[pStart] == 32) then
				pEnd = pStart
			end
		until editor.CharAt[pStart] == 60 or pStart == 0
		if editor.CharAt[pStart + 1] == 47 then return false end
		if pStart == 0 and editor.CharAt[pStart] ~= 60 then return false end
		local tag = editor:textrange(pStart + 1, pEnd)
		editor:InsertText(editor.CurrentPos, "</" .. tag .. ">")
	end

	-- attribute quotes
	if c == "=" then
		local nStyle = editor.StyleAt[editor.CurrentPos - 2]
		if nStyle == 3 or nStyle == 4 then
			editor:InsertText(editor.CurrentPos, "\"\"")
			editor:GotoPos(editor.CurrentPos + 1)
		end
	end

	return false
end

Dreamweaver style xml / html autocomplete

(bugfix posted: 3 July 2008)

Similar to the above (can only use one or the other) but auto closes tags in Dreamweaver style. Each time you type '</' in an XML or HTML file it looks for the corresponding opening tag and auto finishes it for you.

e.g. You type

<html><body>test</

and autocomplete finishes the tag as

<html><body>test</body>
