guess_language

Picks a SourceLanguage 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;
  lang = gtk_source_language_manager_guess_language (filename, NULL);
  gtk_source_buffer_set_language (buffer, lang);

or

  GtkSourceLanguage *lang = NULL;
  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;
    }

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

  g_free (content_type);

etc. Use get_mime_types and get_globs if you need full control over file -> language mapping.

Parameters:

this	a SourceLanguageManager.
filename	a filename in Glib filename encoding, or null.
content_type	a content type (as in GIO API), or null.

Returns:

a SourceLanguage, or null if there is no suitable language for given filename and/or content_type. Return value is owned by this and should not be freed.
