I prepared that config.vala [1].
In general it looks like, that:
public string home = Environment.get_home_dir ();
public string publican_home {get {_pathhome = home +
(string)Path.DIR_SEPARATOR + "/publisher-projects"; return _pathhome;}}
can't used because of it itn't instancable. But how can i work with such
pathes instead?
Also i added a metod which imports the settings from the gsettings
schema and connects this to its properties from the interface. Is the
implementation usable in that case? It would be great, that the
gsettings and the defined pathes are useable inside each other class.
Greetings

After that changes the make process goes to the end now. Thanks for helping.

I tried it out:
private string _filename;
private string _path;
private string entity_file_suffix = ".ent";
private string entity_file_local = {get {_filename =
publication_title + entity_file_suffix; return _filename;}}
private string project_dir = {get {_path = target_dir +
Path.DIR_SEPARATOR + publication_title + Path.DIR_SEPARATOR +
create_language; return _path;}}
But got the same compiler error:

expected `}'
private string entity_file_local = {get {_filename =
publication_title + entity_file_suffix; return _filename;}}
^

private string project_dir = {get {_path = target_dir +

create_language; return _path;}}

Good point. Thank you, i'll changed it.

I tried it out in that way:
// Constants used by create_publication_core
private string _filename;
private string _path;
private const string REV_HIST = "Revision_History.xml";
private const string AUTHOR_GROUP = "Author_Group.xml";
private const string ENTITY_FILE_SUFFIX = ".ent";
private const string DIRECTORY_SEPARATOR_CHAR = "/";
private const string ENTITY_FILE_LOCAL = {get {_filename =
publication_title + ENTITY_FILE_SUFFIX; return _filename;}}
private const string PROJECT_DIR = {get {_path = target_dir +
DIRECTORY_SEPARATOR_CHAR + publication_title + DIRECTORY_SEPARATOR_CHAR
+ create_language; return _path;}}
The compiler says:
core/create_publication_core.vala:51.48-51.48: error: syntax error,
expected `}'
private const string ENTITY_FILE_LOCAL = {get {_filename =
publication_title + ENTITY_FILE_SUFFIX; return _filename;}}
^
core/create_publication_core.vala:52.42-52.42: error: syntax error,
expected `}'
private const string PROJECT_DIR = {get {_path = target_dir +
DIRECTORY_SEPARATOR_CHAR + publication_title + DIRECTORY_SEPARATOR_CHAR
+ create_language; return _path;}}
Maybe i miss anything?

[Vala] Gtk.FileChooserButton
Hello list,
i tried out to get a special folder from a Gtk.FileChooserButton.
In Mono/Gtk-Sharp i used:
public string RevUpdFolder { get; set; }
[Builder.Object] private FileChooserButton FileChooserRevUpd;
protected void OnFileChooserRevUpdFileSet(object sender, EventArgs e)
{
RevUpdFolder = FileChooserRevUpd.CurrentFolder;
}
In Vala i tried to port it:
public string revupdfolder { get; set; }
[Gtk.Child] private Gtk.FileChooserButton fileChooserRevUpd;
private void on_fileChooserRevUpd_file_set () {
revupdfolder = fileChooserRevUpd.current_folder;
}
But it looks like there is no way to get the current folder like
Gtk-Sharp it does, or?

i created a class what contains:

// on_cboDocType_changed gets the chosen document type
[GtkCallback]

But as far as i know the combobox text is a string. So it should work.
What can i do?
