## Detailed Description

Class which provides access to SourceLanguages.

SourceLanguageManager is a class which processes language description files and creates and stores SourceLanguage objects, and provides API to access them.

Use get_default() to retrieve the default instance of SourceLanguageManager, and guess_language() to get a SourceLanguage for given file name and content type.

## Member Function Documentation

static Glib::RefPtr<SourceLanguageManager> gtksourceview::SourceLanguageManager::create | ( |  | ) | `[static]`

Creates a new language manager.

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

Returns: A SourceLanguageManager.

static Glib::RefPtr<SourceLanguageManager> gtksourceview::SourceLanguageManager::get_default | ( |  | ) | `[static]`

Returns the default SourceLanguageManager instance.

Returns: A SourceLanguageManager.

Glib::RefPtr<SourceLanguage> gtksourceview::SourceLanguageManager::get_language | ( | const Glib::ustring & | id | ) |

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

Parameters:

  id | A language id.

Returns:
  A SourceLanguage, or empty Glib::RefPtr if there is no language identified by the given id.

Glib::RefPtr<const SourceLanguage> gtksourceview::SourceLanguageManager::get_language | ( | const Glib::ustring & | id | ) | const

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

Parameters:

  id | A language id.

Returns:
  A SourceLanguage, or empty Glib::RefPtr if there is no language identified by the given id.

Glib::StringArrayHandle gtksourceview::SourceLanguageManager::get_language_ids | ( |  | ) | const

Returns the ids of the available languages.

Returns:
  An array of string containing the ids of the available languages.

Glib::StringArrayHandle gtksourceview::SourceLanguageManager::get_search_path | ( |  | ) | const

Gets the list directories where language manager looks for language files.

Returns:
  An array containg a list of language files directories.

Glib::RefPtr<SourceLanguage> gtksourceview::SourceLanguageManager::guess_language | ( | const Glib::ustring & | filename,
|  | const Glib::ustring & | content_type
| ) |  |

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

Either filename or content_type may be an empty string. This function can be used as follows:

     Glib::RefPtr<SourceLanguage> lang;
     lang = lm->guess_language(filename, Glib::ustring());
     buffer->set_language(lang);

or

     Glib::RefPtr<SourceLanguage> lang;
     bool result_uncertain = FALSE;
     Glib::ustring content_type;

     content_type = Gio::content_type_guess(filename, 0, 0, &result_uncertain);
     if (result_uncertain)
     {
       content_type.clear();
     }

     lang = lm->guess_language(filename, content_type);
     buffer->set_language(lang);

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

Parameters:

  filename | A filename, or empty string.
  content_type | A content type (as in GIO API), or empty string.

Returns:
  A SourceLanguage, or empty Glib::RefPtr if there is no suitable language for given filename and/or content_type.

Glib::RefPtr<const SourceLanguage> gtksourceview::SourceLanguageManager::guess_language | ( | const Glib::ustring & | filename,
|  | const Glib::ustring & | content_type
| ) |  | const

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

Either filename or content_type may be an empty string. This function can be used as follows:

     Glib::RefPtr<SourceLanguageManager> lm = SourceLanguageManager::get_default();
     Glib::RefPtr<SourceLanguage> lang;
     Glib::RefPtr<SourceBuffer> buffer = SourceBuffer::create();
     lang = lm->guess_language(filename, Glib::ustring());
     buffer->set_language(lang);
     // or just:
     // Glib::RefPtr<SourceBuffer> buffer = SourceBuffer::create(lang);

or

     Glib::RefPtr<SourceLanguage> lang;
     Glib::RefPtr<SourceLanguageManager> lm = SourceLanguageManager::get_default();
     Glib::RefPtr<SourceBuffer> buffer = SourceBuffer::create();
     bool result_uncertain = FALSE;
     Glib::ustring content_type;

     content_type = Gio::content_type_guess(filename, 0, 0, &result_uncertain);
     if (result_uncertain)
     {
       content_type.clear();
     }

     lang = lm->guess_language(filename, content_type);
     buffer->set_language(lang);
     // or just:
     // Glib::RefPtr<SourceBuffer> buffer = SourceBuffer::create(lang);

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

Parameters:

  filename | A filename, or empty string.
  content_type | A content type (as in GIO API), or empty string.

Returns:
  A SourceLanguage, or empty Glib::RefPtr if there is no suitable language for given filename and/or content_type.

void gtksourceview::SourceLanguageManager::reset_search_path | ( |  | ) |

Resets the list of directories where the language manager looks for language files to default.

Note:
  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 SourceLanguageManager, you have to call this function right after creating it.

void gtksourceview::SourceLanguageManager::set_search_path | ( | const Glib::StringArrayHandle & | dirs | ) |

Sets the list of directories where the language manager looks for language files.

Note:
  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 SourceLanguageManager, you have to call this function right after creating it.

Parameters:

  dirs | An empty string terminated array of strings.

Glib::RefPtr< gtksourceview::SourceLanguageManager > wrap | ( | GtkSourceLanguageManager * | object,
|  | bool | take_copy = `false`
| ) |  | `[related]`

A Glib::wrap() method for this object.

Parameters:
