LanguageManager.guessLanguage

gtksource.language.Language guessLanguage(string filename = null, string contentType = null)

Picks a classLanguage for given file name and content type, according to the information in lang files.

Either filename or content_type may be null. This function can be used as follows:

GtkSourceLanguage *lang;
GtkSourceLanguageManager *manager;
lm = gtk_source_language_manager_get_default ();
lang = gtk_source_language_manager_guess_language (manager, filename, NULL);
gtk_source_buffer_set_language (buffer, lang);

GtkSourceLanguage *lang = NULL;
GtkSourceLanguageManager *manager;
gboolean result_uncertain;
gchar *content_type;

content_type = g_content_type_guess (filename, NULL, 0, &result_uncertain);
if (result_uncertain)
 {
   g_free (content_type);
   content_type = NULL;
 }

manager = gtk_source_language_manager_get_default ();
lang = gtk_source_language_manager_guess_language (manager, filename, content_type);
gtk_source_buffer_set_language (buffer, lang);

g_free (content_type);

etc. Use [gtksource.language.Language.getMimeTypes] and [gtksource.language.Language.getGlobs] if you need full control over file -> language mapping.

Parameters

`filename`	a filename in Glib filename encoding, or null.
`contentType`	a content type (as in GIO API), or null.

Returns

a #GtkSourceLanguage, or null if there

is no suitable language for given filename and/or content_type. Return value is owned by lm and should not be freed.
