GtkSource.SnippetManager.list_matching

### Method

# GtkSource SnippetManagerlist_matching

#### Declaration [src]

    GListModel*
    gtk_source_snippet_manager_list_matching (
      GtkSourceSnippetManager* self,
      const gchar* group,
      const gchar* language_id,
      const gchar* trigger_prefix
    )

#### Description [src]

Queries the known snippets for those matching `group`, `language_id`, and/or `trigger_prefix`.

If any of these are `NULL`, they will be ignored when filtering the available snippets.

The `GListModel` only contains information about the available snippets until `g_list_model_get_item()` is called for a specific snippet. This helps reduce the number of `GObject`‘s that are created at runtime to those needed by the calling application.

#### Parameters

`group` | `const gchar*`
| A group name or `NULL`.
| The argument can be `NULL`.
| The data is owned by the caller of the function.
| The value is a NUL terminated UTF-8 string.
`language_id` | `const gchar*`
| A `GtkSourceLanguage:id` or `NULL`.
| The argument can be `NULL`.
| The data is owned by the caller of the function.
| The value is a NUL terminated UTF-8 string.
`trigger_prefix` | `const gchar*`
| A prefix for a trigger to activate.
| The argument can be `NULL`.
| The data is owned by the caller of the function.
| The value is a NUL terminated UTF-8 string.

#### Return value

Returns: | A list model of `GObject`
| A `GListModel` of `GtkSourceSnippet`.
| The caller of the method takes ownership of the data, and is responsible for freeing it.
