73 * @title: Key-value file parser
74 * @short_description: parses .ini-like config files
76 * #GKeyFile lets you parse, edit or create files containing groups of
77 * key-value pairs, which we call <firstterm>key files</firstterm> for
78 * lack of a better name. Several freedesktop.org specifications use
79 * key files now, e.g the
80 * [Desktop Entry Specification](http://freedesktop.org/Standards/desktop-entry-spec)
82 * [Icon Theme Specification](http://freedesktop.org/Standards/icon-theme-spec).
84 * The syntax of key files is described in detail in the
85 * [Desktop Entry Specification](http://freedesktop.org/Standards/desktop-entry-spec),
86 * here is a quick summary: Key files
87 * consists of groups of key-value pairs, interspersed with comments.
90 * # this is just an example
91 * # there can be comments before the first group
95 * Name=Key File Example\tthis value shows\nescaping
97 * # localized strings are stored in multiple key-value pairs
100 * Welcome[fr_FR]=Bonjour
102 * Welcome[be@latin]=Hello
106 * Numbers=2;20;-200;0
108 * Booleans=true;false;true;true
111 * Lines beginning with a '#' and blank lines are considered comments.
113 * Groups are started by a header line containing the group name enclosed
114 * in '[' and ']', and ended implicitly by the start of the next group or
115 * the end of the file. Each key-value pair must be contained in a group.
117 * Key-value pairs generally have the form <literal>key=value</literal>,
118 * with the exception of localized strings, which have the form
119 * <literal>key[locale]=value</literal>, with a locale identifier of the
120 * form <literal>lang_COUNTRY\@MODIFIER</literal>
121 * where <literal>COUNTRY</literal> and <literal>MODIFIER</literal>
123 * Space before and after the '=' character are ignored. Newline, tab,
124 * carriage return and backslash characters in value are escaped as \n,
125 * \t, \r, and \\, respectively. To preserve leading spaces in values,
126 * these can also be escaped as \s.
128 * Key files can store strings (possibly with localized variants), integers,
129 * booleans and lists of these. Lists are separated by a separator character,
130 * typically ';' or ','. To use the list separator character in a value in
131 * a list, it has to be escaped by prefixing it with a backslash.
133 * This syntax is obviously inspired by the .ini files commonly met
134 * on Windows, but there are some important differences:
136 * - .ini files use the ';' character to begin comments,
137 * key files use the '#' character.
139 * - Key files do not allow for ungrouped keys meaning only
140 * comments can precede the first group.
142 * - Key files are always encoded in UTF-8.
144 * - Key and Group names are case-sensitive. For example, a group called
145 * [GROUP] is a different from [group].
147 * - .ini files don't have a strongly typed boolean entry type,
148 * they only have GetProfileInt(). In key files, only
149 * true and false (in lower case) are allowed.
151 * Note that in contrast to the
152 * [Desktop Entry Specification](http://freedesktop.org/Standards/desktop-entry-spec),
153 * groups in key files may contain the same
154 * key multiple times; the last entry wins. Key files may also contain
155 * multiple groups with the same name; they are merged together.
156 * Another difference is that keys and group names in key files are not
157 * restricted to ASCII characters.
163 * Error domain for key file parsing. Errors in this domain will
164 * be from the #GKeyFileError enumeration.
166 * See #GError for information on error domains.
171 * @G_KEY_FILE_ERROR_UNKNOWN_ENCODING: the text being parsed was in
172 * an unknown encoding
173 * @G_KEY_FILE_ERROR_PARSE: document was ill-formed
174 * @G_KEY_FILE_ERROR_NOT_FOUND: the file was not found
175 * @G_KEY_FILE_ERROR_KEY_NOT_FOUND: a requested key was not found
176 * @G_KEY_FILE_ERROR_GROUP_NOT_FOUND: a requested group was not found
177 * @G_KEY_FILE_ERROR_INVALID_VALUE: a value could not be parsed
179 * Error codes returned by key file parsing.
184 * @G_KEY_FILE_NONE: No flags, default behaviour
185 * @G_KEY_FILE_KEEP_COMMENTS: Use this flag if you plan to write the
186 * (possibly modified) contents of the key file back to a file;
187 * otherwise all comments will be lost when the key file is
189 * @G_KEY_FILE_KEEP_TRANSLATIONS: Use this flag if you plan to write the
190 * (possibly modified) contents of the key file back to a file;
191 * otherwise only the translations for the current language will be
194 * Flags which influence the parsing.
198 * G_KEY_FILE_DESKTOP_GROUP:
