GtkSource.SearchContext.replace

### Method

# GtkSource SearchContextreplace

#### Declaration [src]

    gboolean
    gtk_source_search_context_replace (
      GtkSourceSearchContext* search,
      GtkTextIter* match_start,
      GtkTextIter* match_end,
      const gchar* replace,
      gint replace_length,
      GError** error
    )

#### Description [src]

Replaces a search match by another text. If `match_start` and `match_end` doesn’t correspond to a search match, `FALSE` is returned.

`match_start` and `match_end` iters are revalidated to point to the replacement text boundaries.

For a regular expression replacement, you can check if `replace` is valid by calling `g_regex_check_replacement()`. The `replace` text can contain backreferences.

#### Parameters

`match_start` | `GtkTextIter`
| The start of the match to replace.
| The data is owned by the caller of the function.
`match_end` | `GtkTextIter`
| The end of the match to replace.
| The data is owned by the caller of the function.
`replace` | `const gchar*`
| The replacement text.
| The data is owned by the caller of the function.
| The value is a NUL terminated UTF-8 string.
`replace_length` | `gint`
| The length of `replace` in bytes, or -1.
`error` | `GError **`
| The return location for a `GError*`, or `NULL`.

#### Return value

Returns: | `gboolean`
| Whether the match has been replaced.
