Lua Programming IDE

Lua Programming IDE

Hi all,

Just thought I'd let you know that ZeroBrane Studio ( is a great open source app for testing Lua code. It obviously can't use Skyline specific functions, but great for pure Lua!

As an example, I wanted to write some code that extracted specific parts of the MAME xml file (120MB in size and crashed most of my desktop xml editors :(). I initially thought of using Python or C++ and decided that was probably overkill as it could be done so easily in Lua ;)

Here's the code that took me all of 10 minutes to write and works perfectly for what I needed:

Code: Select all
fh, err ="mame.xml")

if err then print("Oops!")

-- Open a file for write
fho, err ="controls.xml","w")

-- line by line
while true do
    line = fh:read()
    if (line == nil) then
    if string.find(line, "<machine") or
      string.find(line, "<description") or
      string.find(line, "<control") or
      string.find(line,"<input") or
      string.find(line, "</input>") or
      string.find(line, "</machine") then

-- Following are good form

Basically, it reads in the xml file line by line, checks for certain tags and saves the lines with those tags to another file.

ZeroBrane runs on Windows, Mac & Linux, can use different versions of Lua (with debugging support for 5.1, 5,2 etc.) and is great for "live" coding.

Here's a quick feature list:

    Small, portable, open-source, and cross-platform (Windows, MacOS, and Linux);
    Auto-completion for functions, keywords, and custom APIs;
    Syntax highlighting and folding for 110+ languages and file formats;
    Project view with auto-refresh and ability to hide files and directories from the list;
    Interactive console to test Lua code snippets with local and remote execution;
    Integrated debugger with support for local and remote debugging, including cross-platform and on-device debugging;
    Live coding with Lua, LÖVE, Gideros, Moai, Corona, GSL-Shell and other Lua engines;
    50+ extension packages in the package repository;
    Fuzzy search for files, symbols, and library functions, function outline, and more.

So, if you're looking to write Lua "on-the-go" and don't need access to Skyline functions, this is a great little IDE that I highly recommend!

Hope this helps someone.


PS: Forgot to mention that as it's written in Lua, it can be extended in Lua as well!!!
