Description

GtkSourceLanguageManager is an object which processes language description files and creates and stores GtkSourceLanguage objects, and provides API to access them. Use gtk_source_language_manager_get_default() to retrieve the default instance of GtkSourceLanguageManager, and gtk_source_language_manager_guess_language() to get a GtkSourceLanguage for given file name and content type.

Functions

gtk_source_language_manager_new ()

GtkSourceLanguageManager *
gtk_source_language_manager_new (void);

Creates a new language manager. If you do not need more than one language manager or a private language manager instance then use gtk_source_language_manager_get_default() instead.

Returns

a new GtkSourceLanguageManager.

gtk_source_language_manager_get_default ()

GtkSourceLanguageManager *
gtk_source_language_manager_get_default
                               (void);

Returns the default GtkSourceLanguageManager instance.

Returns

a GtkSourceLanguageManager. Return value is owned by GtkSourceView library and must not be unref'ed.

gtk_source_language_manager_set_search_path ()

void
gtk_source_language_manager_set_search_path
                               (GtkSourceLanguageManager *lm,
                                gchar **dirs);

Sets the list of directories where the lm looks for language files. If dirs is NULL, the search path is reset to default.

At the moment this function can be called only before the language files are loaded for the first time. In practice to set a custom search path for a GtkSourceLanguageManager, you have to call this function right after creating it.

Parameters

lm	a GtkSourceLanguageManager.
dirs	a `NULL`-terminated array of strings or `NULL`.	[nullable][array zero-terminated=1]

gtk_source_language_manager_get_search_path ()

const gchar * const *
gtk_source_language_manager_get_search_path
                               (GtkSourceLanguageManager *lm);

Gets the list directories where lm looks for language files.

Parameters

a GtkSourceLanguageManager.

Returns

NULL-terminated array containg a list of language files directories. The array is owned by lm and must not be modified.

[array zero-terminated=1][transfer none]

gtk_source_language_manager_get_language_ids ()

const gchar * const *
gtk_source_language_manager_get_language_ids
                               (GtkSourceLanguageManager *lm);

Returns the ids of the available languages.

Parameters

a GtkSourceLanguageManager.

Returns

a NULL-terminated array of strings containing the ids of the available languages or NULL if no language is available. The array is sorted alphabetically according to the language name. The array is owned by lm and must not be modified.

[nullable][array zero-terminated=1][transfer none]

gtk_source_language_manager_get_language ()

GtkSourceLanguage *
gtk_source_language_manager_get_language
                               (GtkSourceLanguageManager *lm,
                                const gchar *id);

Gets the GtkSourceLanguage identified by the given id in the language manager.

Parameters

lm	a GtkSourceLanguageManager.
id	a language id.

Returns

a GtkSourceLanguage, or NULL if there is no language identified by the given id . Return value is owned by lm and should not be freed.

gtk_source_language_manager_guess_language ()

GtkSourceLanguage *
gtk_source_language_manager_guess_language
                               (GtkSourceLanguageManager *lm,
                                const gchar *filename,
                                const gchar *content_type);

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:

1
2
3

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

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 gtk_source_language_get_mime_types() and gtk_source_language_get_globs() if you need full control over file -> language mapping.

Parameters

lm	a GtkSourceLanguageManager.
filename	a filename in Glib filename encoding, or `NULL`.	[nullable]
content_type	a content type (as in GIO API), or `NULL`.	[nullable]

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.
