[Wxlua-users] patch for wxluaedit cmd line parser

[Francesco M. <f18...@ya...>]

Hi John,
    I've created a little patch for wxLuaEdit to make it possible to 
call it from command line with .lua files to open directly in the editor.

This patch will make life a lot easier for win32 and also unix users IMO.

Can I apply it ?

Francesco

PS: the patch works ok when you specify zero or one file in the command 
line. When you specify two or more, wxLuaEditor opens only the last.
This is not a bug with my patch but seems something scintilla-related: I 
get the same behaviour using the File->Open cmd. I.e. the new files I 
load do not go as additional items in the "Files" splitterwnd but rather 
replace the already-open file.
Is it because of wxCVS ?
I'm going to do a cvs update and recompile...
