If a non-existing file is specified with the command "core:open-file"
a new document is opened with the given filename provided the directory
already exists.
The flag new_file is set to true in the Doc instance.
The file will be actually created only when the "save" command is used.
The document will be marked with the "*" event when no changes are done
to mean that it is a new file and is not yet saved.
The function common.normalize_path now process the .. and . in the
filename. Before was not needed because system.absolute_path already
get rid of them but now we need to have the absolute path of files
that not yet exists so we cannot use system.absolute_path.
Added in a validation function which fires before submitting a command enter; found it incredibly irritating to try to open something, hit enter, only to be told I'd selected a directory, and then have to go through the whole process again. (#175)
It make sense to not put the initial '/' in the filename as the name
is relative to the top directory it belongs to.
By removing the the initial '/' in the filename we can re-introduce the
variable
core.project_files
to stay compatible with standard Lite. The project_files variable will
always point to the files table of the first entry of
core.project_directories.
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'.
