Programming and Scripting :: murgaLua tests



Wow

Thanks for the tests ... I am currently traveling, but I hope to release a new version soon and will incorporate your feedback (and if it's OK), some of your tests.

I have some fixes and additions to the FLTK stuff and changes to the sqLite stuff that should reduce the size of the runtime.

Cheers

sweet! =o)

Just please don't include the full ucitool (parts are fine, if anything is of use to you), since it is incomplete and represents the DSL project to an extent.
ucitool update

Shows mounted and available uci packages, and includes a very basic uci builder.  What this builder does is simply create a cloop from a chosen directory and place it in the current directory. I had considered adding more features to the builder, but i came to the conclusion that it would make the script much too complex for what little benefit it would give.

The directory containing available uci packages is /cdrom/mydsl/optional by default, but can be changed by setting the UCITOOL_DIR environment variable or by browsing from within the application.

EDIT: cleared up some misplaced/vague comments
EDIT2: fixed the multiple slash issue
EDIT3: sorted uci list and joined the mount & umount functions
A couple of changes...removed the "about" tab and fixed a build problem with md5sum not finding the package if you're not in $HOME.
I have to work on the default uci location...probably use /opt/.mydsl_dir to be consistent with other DSL tools.

Here's a murgaLua frontend for the xdesktopwaves application.
It should work with the xdesktopwaves mydsl extension, but you may need to change the "program" variable to point to the proper executable. I think it's /opt/xdesktopwaves/xdesktopwaves, but I can't recall exactly.
As always, feedback is appreciated.

Latest update: Feb 07, 2007

-- A MurgaLua frontend for xdesktopwaves.
-- This does not cover all options, but should provide a decent
-- amount of control for most features.
-- Note: The 'z' variables are placeholders..dunno if there's a better way

-- Changelog
-- 2007-02-07: Custom colors persist for fl_color_chooser
--             Colors are set accurately with set_color instead of fl_color_cube
--             Tooltips added in case of too-dark color
--             More code cleanup
-- 2007-02-05: Fixed fl_color_chooser not ignoring change when cancelled
--             Code cleanup
-- 2007-02-04: Dumped Lua-FLTK
--             Added custom color controls
-- 2006-10-28: Can use either Lua-FLTK or MurgaLua
--             Removed unnecessary stuff (decoration, about, version, rc file)
-- 2005-01-28: First version (Lua-FLTK)
