Use resolved executablePath instead of resourcePath to allow lanching
the lite-xl binary via a symlink, like typically done by Homebrew:
/usr/local/bin/lite-xl -> /Applications/lite-xl.app/Contents/MacOS/lite-xl
The resourcePath returns /usr/local in this case instead of
/Applications/lite-xl.app/Contents/Resources, which makes later
access to the resource files fail. Resolving the symlink to the
executable and then the relative path to the expected directory
Resources is a workaround for starting the application from both
the launcher directly and the command line via the symlink.
In some cases rencache was using a FontDesc pointer that was actually freed by
Lua giving segfaults errors.
In addition, some FontDesc object were not freed in some cases if the
rencache_end_frame was not called when performing the "restart" command.
The invalid access problem can happen because rencache keep some pointers to
FontDesc object but these are Lua userdata that Lua can dispose of. This
situation is prone to hard errors and we should avoid to keep pointers to
objects managed by Lua.
To this purpose we use luaL_ref/unref to bind the FontDesc into the Lua's
registry while rencache need them. We still keeps pointer to FontDesc object but
using luaL_ref we are assured they will not be disposed by Lua.
Since we are using luaL_ref/unref to inform the GC about when the objects are in
use we can now finalize the objects directly when Lua collects them. Previously
the GC metamethods was issuing a FREE command to rencache and the font was
actually freed only from the rencache_end_frame function.
Add a Meson option "portable" to choose between "portable" and unix-like
directories. Add information about this option in the README.
To determine the user's directory use the variable USERPROFILE only on
Windows and use HOME otherwise.
Implement the "portable" option in the package build script.
Create the user's config init file if lite user's config directory does
not exists.
No longer use the awkward package.searchers but instead add user's
config dir at the end of package path.
It basically works by setting the data directory to
$prefix/share/lite-xl
where $prefix is determined so that $prefix/bin corresponds to EXEDIR.
The packages 'user' and 'user.*' are loaded from the directory
'$HOME/.config/lite-xl'.
