WowLua

WowLua is an in-game Lua scripting environment that includes an interactive Lua interpreter as well as a multi-page script editor. Other features include:

* Syntax coloring, courtesy of krka's spectacular For All Indents and Purposes library
* Sleek buttons, courtesy of Mikk
* When WowLua is running code, it defines a global function print() which directs output to the WowLua window, for convenience. This global is removed when not running from WowLua
* Can open WowLua using /wowlua or /lua. Both of these slash commands will take a lua expression and run it, if provided:

/lua print(14) will open WowLua and print the number 14 to the output window.

Please feel free to post any comments or questions here, you'll find I'm relatively responsible. This addon has been written primarily as a companion tool for World of Warcraft Programming: A Guide and Reference for Creating WoW Addons.

I'll look into the first, but the naming isn't something I really plan to change right now. It helps prevent any duplicates without having to do any checking.

Heya, I think that the option would be handy to have.

Anyhow, it's awesome, great job mate.

Cladhaire Salad! Forum posts: 1473 File comments: 3156 Uploads: 15	I've added an undo/redo system to WowLua as well as a set of keybindings to Run/Save the current page. Please play with the undo/redo system before relying on it as there may still be some edge cases where it may not behave as expected. The "undo" points are whenever you run or save the code.

You'd need to give us at the very least a stack traceback.. or the code that is calling into the UI template, etc. The easiest way to get a stack traceback is to download and install Swatter, a bug-tracking addon:

It means someone or something is calling the function that's on or near line 32, and being passed incorrect arguments. Most specifically you probably need to pass the frame as the first argument to that function. However, without more information, it's almost impossible to tell.

Excellent addon, and a very good replacement for myDebug which is now broken. I have two suggestions:

1) Add the following code to the toc:

## LoadManagers: AddonLoader
## X-LoadOn-Slash: /wowlua, /lua

This allows it to load automatically when the slash command is executed, if AddonLoader is installed. Otherwise it is just ignored. This saves the load time for those 99/100 sessions where you're not using it.

2) Use something else than print, as that symbol is now already in the global namespace for use by addons (it was introduced in 3.0.2 i believe).

The .TOC changes have been made. I had meant to put AddonLoader support in a while ago, so the code should support it just fine. As for changing the name of the print function, I have no plans to do that at this time. This addon is meant to be able to act as a Lua interpreter, and that means taking code that works in stock Lua and having it work here.

It should not redefine the global print function, which you can still access via getfenv(0).print, if desired.

Code:

local function dropDownFunc(page)
	WowLua:GoToPage(page)
end

needs to be changed to

Code:

local function dropDownFunc(btn, page)
	WowLua:GoToPage(page)
end

Oh and could you please either remove the Undo button or implement a Redo? ATM this "Undo" just loads the previously saved version of the script. All this button ever did for me was destroy work, because I accidentally clicked it when I wanted to click Save.
An Undo without Redo is no real Undo IMHO. What I would love to see is an undo queue. Every time the script is executed, the current version is saved to the queue (unless it wasn't changed of course). Undo loads the previous script from the queue, Redo the next. The queue is flushed when another page is loaded. It's not hard to implement, you just have to maintain the current position in the queue, and remove stuff after this position when a new item enters the queue.

Code:

local queue, queuePos = {}, 0
local function queueFlush(all)
	if all then
		table.wipe(queue)
		queuePos = 0
	end
end
local function queueAction(text)
	if text ~= queue[queuePos] then
		queuePos = queuePos+1
		queue[queuePos] = text
		for i=queuePos+1,#queue do
			queue[i]=nil
		end
	end
end
local function queueUndo()
	local item = queue[queuePos-1]
	if item then 
		queuePos = queuePos-1
		return item
	end
	return queue[queuePos]
end
local function queueRedo()
	local item = queue[queuePos+1]
	if item then
		queuePos = queuePos+1
		return item
	end
	return queue[queuePos]
end

function WowLua:Button_Undo()
	local page, entry = self:GetCurrentPage()
	WowLuaFrameEditBox:SetText(queueUndo() or entry.content)
end
function WowLua:Button_Redo()
	local page, entry = self:GetCurrentPage()
	WowLuaFrameEditBox:SetText(queueRedo())
end
function WowLua:Button_Run()
	local text = WowLuaFrameEditBox:GetText()
	
	-- Run the script, if there is an error then highlight it
	if text then
		local succ,err = WowLua:RunScript(text)
		if not succ then
			local chunkName,lineNum = err:match("(%b[]):(%d+):")
			lineNum = tonumber(lineNum)
			WowLua:UpdateLineNums(lineNum)

			-- Highlight the text in the editor by finding the char of the line number we're on
			text = WowLua.indent.coloredGetText(WowLuaFrameEditBox)

			local curLine,start = 1,1
			while curLine < lineNum do
				local s,e = text:find("\n", start)
				start = e + 1
				curLine = curLine + 1
			end

			local nextLine = select(2, text:find("\n", start))
			
			WowLuaFrameEditBox:SetFocus()
			WowLuaFrameEditBox:SetCursorPosition(start - 1)
		else
			queueAction(text)
		end
	end
end
