LanguageManager.guessLanguage

Picks a #GtkSourceLanguage 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:

<informalexample><programlisting>

GtkSourceLanguage *lang; lang = gtk_source_language_manager_guess_language (filename, NULL); gtk_source_buffer_set_language (buffer, lang);

</programlisting></informalexample>

or

<informalexample><programlisting>

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);

</programlisting></informalexample>

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