Usage

In this example, we packages the language-specs in our Build.PKGDATADIR/gtksourceview-4/language-specs.

    Gtk.SourceLanguageManager thief_languages;
    public Gtk.SourceLanguageManager get_language_manager () {
        if (thief_languages == null) {
            thief_languages = new Gtk.SourceLanguageManager ();
            string custom_languages = Path.build_path (
                Path.DIR_SEPARATOR_S,
                Build.PKGDATADIR,
                "gtksourceview-4",
                "language-specs");
            string[] language_paths = {
                custom_languages
            };
            thief_languages.set_search_path (language_paths);

            var markdown = thief_languages.get_language ("markdown");
            if (markdown == null) {
                warning ("Could not load custom languages");
                thief_languages = Gtk.SourceLanguageManager.get_default ();
            }
        }

        return thief_languages;
    }

Inside of our editor, we can do:

var languages = get_language_manager ();
var markdown_syntax = languages.get_language ("markdown");
Gtk.SourceBuffer buffer = new Gtk.SourceBuffer.with_language (markdown);
Gtk.SourceView view = new Gtk.SourceView.with_buffer (buffer);
