commit 5a4c3330261b320a7f96d400ea18bae5d9e343a9
Author: Sébastien Wilmet <swilmet gnome org>

File saving
Add the public class GtkSourceFile.
Add the private class GtkSourceFileSaver, taken from gedit
(GeditDocumentSaver) and adapted to fit the GtkSourceFile API.
GtkSourceFile binds a GtkSourceBuffer with a GFile. There are properties
for common things between the saving and loading. Specific saving
settings are passed as flags in a function parameter.
GtkSourceFile stores the modification time when a file is saved (and it
will also get the modification time when the file is loaded). See the
GTK_SOURCE_FILE_SAVE_IGNORE_MTIME flag, and the
GTK_SOURCE_FILE_ERROR_EXTERNALLY_MODIFIED error. Currently, when saving
the file for the first time, the mtime is not known, so the IGNORE_MTIME
flag is forced.
Differences from gedit:
- gedit uses three signals: save, saving (to report progress) and saved.
gsv uses the GIO conventions for async operations (also to report
progress).
The FileSaver uses a GTask internally.
- for the ensure-trailing-newline setting, gedit uses GSettings, and gsv
has properties.
- for creating backup before saving, gedit has a GSettings, gsv has the
CREATE_BACKUP flag in GtkSourceFileSaveFlags. gedit has also two flags
for backups in the GeditDocumentSaveFlags enum: IGNORE_BACKUP and
PRESERVE_BACKUP. There is a comment for the latter saying that it is
needed for autosaving, but CREATE_BACKUP seems sufficient.
- gedit has the _gedit_document_set_mount_operation_factory() private
function, it is used internally by gedit when creating a
GeditDocument. gsv must make this function public. And it is a pity to
have this function only because it is better to set the parent GtkWindow
to a GtkMountOperation...
