## Description

Functions for writing config info to a file for libgimpconfig.

## Functions

### gimp_config_writer_new_file ()

    GimpConfigWriter *
    gimp_config_writer_new_file (const gchar *filename,
                                 gboolean atomic,
                                 const gchar *header,
                                 GError **error);

Creates a new GimpConfigWriter and sets it up to write to `filename` . If `atomic` is `TRUE`, a temporary file is used to avoid possible race conditions. The temporary file is then moved to `filename` when the writer is closed.

#### Parameters

filename | a filename |
atomic | if `TRUE` the file is written atomically |
header | text to include as comment at the top of the file |
error | return location for errors |

#### Returns

a new GimpConfigWriter or `NULL` in case of an error

Since: 2.4

### gimp_config_writer_open ()

    void
    gimp_config_writer_open (GimpConfigWriter *writer,
                             const gchar *name);

This function writes the opening parenthesis followed by `name` . It also increases the indentation level and sets a mark that can be used by `gimp_config_writer_revert()`.

#### Parameters

writer | a GimpConfigWriter |
name | name of the element to open |

Since: 2.4

### gimp_config_writer_comment_mode ()

    void
    gimp_config_writer_comment_mode (GimpConfigWriter *writer,
                                     gboolean enable);

This function toggles whether the `writer` should create commented or uncommented output. This feature is used to generate the system-wide installed gimprc that documents the default settings.

Since comments have to start at the beginning of a line, this function will insert a newline if necessary.

#### Parameters

writer | a GimpConfigWriter |
enable | `TRUE` to enable comment mode, `FALSE` to disable it |

Since: 2.4

### gimp_config_writer_print ()

    void
    gimp_config_writer_print (GimpConfigWriter *writer,
                              const gchar *string,
                              gint len);

Appends a space followed by `string` to the `writer` . Note that string must not contain any special characters that might need to be escaped.

#### Parameters

writer | a GimpConfigWriter |
string | a string to write |
len | number of bytes from `string` or -1 if `string` is NUL-terminated. |

Since: 2.4

### gimp_config_writer_printf ()

    void
    gimp_config_writer_printf (GimpConfigWriter *writer,
                               const gchar *format,
                               ...);

A printf-like function for GimpConfigWriter.

#### Parameters

writer | a GimpConfigWriter |
format | a format string as described for `g_strdup_printf()`. |
... | list of arguments according to `format` |

Reverts all changes to `writer` that were done since the last call to `gimp_config_writer_open()`. This can only work if you didn't call `gimp_config_writer_close()` yet.

#### Parameters

writer | a GimpConfigWriter |

Since: 2.4

### gimp_config_writer_close ()

    void
    gimp_config_writer_close (GimpConfigWriter *writer);

                               GError **error);

This function finishes the work of `writer` and frees it afterwards. It closes all open elements, appends an optional comment and releases all resources allocated by `writer` . You must not access the `writer` afterwards.

#### Parameters

writer | a GimpConfigWriter |
footer | text to include as comment at the bottom of the file |
error | return location for possible errors |

#### Returns

`TRUE` if everything could be successfully written, `FALSE` otherwise
