/**

* SECTION:keyfile
|
||
* @title: Key-value file parser
|
||
* @short_description: parses .ini-like config files
|
||
*
|
||
* #GKeyFile lets you parse, edit or create files containing groups of
|
||
* key-value pairs, which we call "key files" for lack of a better name.
|
||
* Several freedesktop.org specifications use key files now, e.g the
|
||
* [Desktop Entry Specification](http://freedesktop.org/Standards/desktop-entry-spec)
|
||
* and the
|
||
* [Icon Theme Specification](http://freedesktop.org/Standards/icon-theme-spec).
|
||
*
|
||
* The syntax of key files is described in detail in the
|
||
* [Desktop Entry Specification](http://freedesktop.org/Standards/desktop-entry-spec),
|
||
* here is a quick summary: Key files
|
||
* consists of groups of key-value pairs, interspersed with comments.
|
||
*
|
||
* |[
|
||
* # this is just an example
|
||
* # there can be comments before the first group
|
||
*
|
||
* [First Group]
|
||
*
|
||
* Name=Key File Example\tthis value shows\nescaping
|
||
*
|
||
* # localized strings are stored in multiple key-value pairs
|
||
* Welcome=Hello
|
||
* Welcome[de]=Hallo
|
||
* Welcome[fr_FR]=Bonjour
|
||
* Welcome[it]=Ciao
|
||
* Welcome[be@latin]=Hello
|
||
*
|
||
* [Another Group]
|
||
*
|
||
* Numbers=2;20;-200;0
|
||
*
|
||
* Booleans=true;false;true;true
|
||
* ]|
|
||
*
|
||
* Lines beginning with a '#' and blank lines are considered comments.
|
||
*
|
||
* Groups are started by a header line containing the group name enclosed
|
||
* in '[' and ']', and ended implicitly by the start of the next group or
|
||
* the end of the file. Each key-value pair must be contained in a group.
|
||
*
|
||
* Key-value pairs generally have the form `key=value`, with the
|
||
* exception of localized strings, which have the form
|
||
* `key[locale]=value`, with a locale identifier of the
|
||
* form `lang_COUNTRY@MODIFIER` where `COUNTRY` and `MODIFIER`
|
||
* are optional.
|
||
* Space before and after the '=' character are ignored. Newline, tab,
|
||
* carriage return and backslash characters in value are escaped as \n,
|
||
* \t, \r, and \\\\, respectively. To preserve leading spaces in values,
|
||
* these can also be escaped as \s.
|
||
*
|
||
* Key files can store strings (possibly with localized variants), integers,
|
||
* booleans and lists of these. Lists are separated by a separator character,
|
||
* typically ';' or ','. To use the list separator character in a value in
|
||
* a list, it has to be escaped by prefixing it with a backslash.
|
||
*
|
||
* This syntax is obviously inspired by the .ini files commonly met
|
||
* on Windows, but there are some important differences:
|
||
*
|
||
* - .ini files use the ';' character to begin comments,
|
||
* key files use the '#' character.
|
||
*
|
||
* - Key files do not allow for ungrouped keys meaning only
|
||
* comments can precede the first group.
|
||
*
|
||
* - Key files are always encoded in UTF-8.
|
||
*
|
||
* - Key and Group names are case-sensitive. For example, a group called
|
||
* [GROUP] is a different from [group].
|
||
*
|
||
* - .ini files don't have a strongly typed boolean entry type,
|
||
* they only have GetProfileInt(). In key files, only
|
||
* true and false (in lower case) are allowed.
|
||
*
|
||
* Note that in contrast to the
|
||
* [Desktop Entry Specification](http://freedesktop.org/Standards/desktop-entry-spec),
|
||
* groups in key files may contain the same
|
||
* key multiple times; the last entry wins. Key files may also contain
|
||
* multiple groups with the same name; they are merged together.
|
||
* Another difference is that keys and group names in key files are not
|
||
* restricted to ASCII characters.
|
||
*
|
||
* Here is an example of loading a key file and reading a value:
|
||
* |[<!-- language="C" -->
|
||
* g_autoptr(GError) error = NULL;
|
||
* g_autoptr(GKeyFile) key_file = g_key_file_new ();
|
||
*
|
||
* if (!g_key_file_load_from_file (key_file, "key-file.ini", flags, &error))
|
||
* {
|
||
* if (!g_error_matches (error, G_FILE_ERROR, G_FILE_ERROR_NOENT))
|
||
* g_warning ("Error loading key file: %s", error->message);
|
||
* return;
|
||
* }
|
||
*
|
||
* g_autofree gchar *val = g_key_file_get_string (key_file, "Group Name", "SomeKey", &error);
|
||
* if (val == NULL &&
|
||
* !g_error_matches (error, G_KEY_FILE_ERROR, G_KEY_FILE_ERROR_KEY_NOT_FOUND))
|
||
* {
|
||
* g_warning ("Error finding key in key file: %s", error->message);
|
||
* return;
|
||
* }
|
||
* else if (val == NULL)
|
||
* {
|
||
* // Fall back to a default value.
|
||
* val = g_strdup ("default-value");
|
||
* }
|
||
* ]|
|
||
*
|
||
* Here is an example of creating and saving a key file:
|
||
* |[<!-- language="C" -->
|
||
* g_autoptr(GKeyFile) key_file = g_key_file_new ();
|
||
* const gchar *val = …;
|
||
* g_autoptr(GError) error = NULL;
|
||
*
|
||
* g_key_file_set_string (key_file, "Group Name", "SomeKey", val);
|
||
*
|
||
* // Save as a file.
|
||
* if (!g_key_file_save_to_file (key_file, "key-file.ini", &error))
|
||
* {
|
||
* g_warning ("Error saving key file: %s", error->message);
|
||
* return;
|
||
* }
|
||
*
|
||
* // Or store to a GBytes for use elsewhere.
|
||
* gsize data_len;
|
||
* g_autofree guint8 *data = (guint8 *) g_key_file_to_data (key_file, &data_len, &error);
|

* if (data == NULL)
|

|
