Lua Editor Support

Editor support may include syntax highlighting, auto-formatting, syntax checking, build and debug integration, etc.

The following editors have some Lua support (at least highlighting or formatting) out of the box:

Editors requiring 3rd party add-ons, and miscellaneous editor tools:

Comments on Specific Editors

UltraEdit

Add code-folding ability by adding these lines to the syntax highlighting file above:

/Open Fold Strings = "{" /Close Fold Strings = "}"

Xemacs

This tickles XEmacs' syntax highlighting a bit. On the first line place "local x = (x)*(x)*(x)*(x)*(x)*(x)*(x)*(x)*(x)*(x)*(x)*(x)*(x)*(x)*(x)". On the second line type "print()". The hourglass cursor flickers for a few couple seconds after typing the ")". Additional terms cause much longer flicker. Some rexex performance issue I suppose. Xemacs 21.4 (patch 13) i586-pc-win32. --DavidManura, 200703

Here's a fill paragraph (M-q) function for wrapping comments. A similar questions was posted in LuaList:2004-04/msg00320.html , but I didn't see this function in the the latest 20061208 version of lua-mode.el on LuaForge. It can probably be improved from this simple form. --DavidManura, 200703

jEdit

Here's a basic jEdit macro that filters the currently selected text through a Lua function. --DavidManura 

Process p = java.lang.Runtime.getRuntime().exec(
    "lua -e\"io.stdout:write((io.stdin:read'*a':gsub('[a-z]','-')))\"");
BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(p.getOutputStream()));
bw.write(textArea.getSelectedText());
bw.close();

BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));
String text = "";
String buffer;
while ((buffer = br.readLine()) != null) { text += buffer + "\n"; }
textArea.setSelectedText(text);
