WowLua

Version: v40300-1.0.2

by: Cladhaire [More]

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 run WowLua pages from the commandline using /wowluarun or /luarun. Each slash command takes the name of a page, and prints any issues or activity to the chat frame. These can thus be used from macros.
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.

AnrDaemon hit the nail on the head. I understand not wanting to take the addon outside of the scope of its intended purpose. I'll look into your suggestions here, these seem appropriate.

As a follow the addon Hack is exactly what I was looking for. Thanks again for your input.

Cladhaire Salad! Forum posts: 1927 File comments: 4403 Uploads: 18	I'm not sure I want to get that complicated at the moment, since the primary purpose of the addon is editing/interpreter. There are other addons, like Hack, that already do most of what I think you're talking about. __________________ "There's only one thing that I know how to do well and I've often been told that you only can do what you know how to do well, and that's be you-- be what you're like-- be like yourself.

I think, it's already possible.
Just execute a page, that declare a function and hook it to something.
My guess is that he wanted to do that automatically on client startup, but I don't think that would be the right thing to do for WowLua. (edited)
For such things, I have a separate addon, basically a .toc, a loader and a bunch of small files-prototypes/hooks for various things.
You can see the technique in my addons - I think, I moved them all to the same loader structure.

It allows me to manipulate code segments without constantly saving and reloading a file. I applaud your contribution to the community by developing such a tool. One feature I would love to see implemented is, the ability to set saved code spinets to automatically run on selected event triggers. This would make it's usefulness even more fantastic in my opinion.

Cladhaire Salad! Forum posts: 1927 File comments: 4403 Uploads: 18	Just a heads up guys, I move country in under two weeks, have a conference next week, and have committed the next 6-7 weeks of my life to completing my thesis and submitting it. As a result I just do not have the time to get online and test all of the different functions of my addons. If you have access to the MoP beta and are willing to test them out for me and give me good controlled bug reports, I will do my best to make sure I can fix anything before the UI patch hits live. Thanks for all your support!

(Bumped TOC version locally - I always leave "Load out of date addons" disabled so I can differentiate between the addons I've installed that work out of the box with the new patches vs. the ones that need more atention)

and maybe - well this might be some overkill but would be cool for me in some cases (no need to make own event handling code in some scripts) - running scripts based on ingame events :-D

Then write your own addon. It's not like it's unbeatable task.
In reality, it's rather easy. Loader.xml

xml Code:

<Ui xmlns="http://www.blizzard.com/wow/ui/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.blizzard.com/wow/ui/
..\FrameXML\UI.xsd">
    <Script file="Libs\LibStub\LibStub.lua" />
    <Include file="Libs\CallbackHandler-1.0\CallbackHandler-1.0.xml" />
    <Script file="Libs\LibDataBroker-1.1\LibDataBroker-1.1.lua" />
<!-- Put your scripts here -->
    <Script file="MyPrivateStuff.lua" />
</Ui>

Event handling (in this instance - fixing minimap mess):

lua Code:

local frame = CreateFrame("Frame", "MyPrivateStuff_Frame1");
local events = {};
 
-- Call event handler from table
frame:SetScript("OnEvent", function(self, event, ...)
  events[event](self, ...);
end);
 
-- You need a PLAYER_ENTERING_WORLD event handler to wait for all skills to load first.
-- THEN you could try and check for real amount of tracking skills.
 
function events:PLAYER_ENTERING_WORLD(...)
-- Kill useless buttons FFS
  MiniMapWorldMapButton:Hide()
  TimeManagerClockButton:Hide()
  MinimapZoomIn:Hide()
  MinimapZoomOut:Hide()
 
-- Enable scroll-zooming
  Minimap:SetScript("OnMouseWheel", function(self, arg1)
    if arg1 < 0 then Minimap_ZoomIn() else Minimap_ZoomOut() end
  end)
 
  Minimap:EnableMouseWheel(true)
 
-- Move the rest of the buttons to their proper positions
 
  local frame = GameTimeFrame;
  local point, relativeTo, relativePoint, xOffset, yOffset = frame:GetPoint(1);
  frame:ClearAllPoints();
  frame:SetPoint(point, relativeTo, relativePoint, 19, 1);
  frame:SetSize(45, 45);
 
  local frame = MiniMapMailFrame;
  local point, relativeTo, relativePoint, xOffset, yOffset = frame:GetPoint(1);
  frame:ClearAllPoints();
  frame:SetPoint(point, relativeTo, relativePoint, 21, -35);
 
  local frame = MiniMapTracking;
  local point, relativeTo, relativePoint, xOffset, yOffset = frame:GetPoint(1)
  frame:ClearAllPoints();
  frame:SetPoint(point, relativeTo, relativePoint, 16, -29);
 
  self:UnregisterAllEvents();
 
end;
 
-- Register all events, for which handlers have been defined
for k, v in pairs(events) do
  frame:RegisterEvent(k);
end;
