72 * @title: Key-value file parser
73 * @short_description: parses .ini-like config files
75 * #GKeyFile lets you parse, edit or create files containing groups of
76 * key-value pairs, which we call <firstterm>key files</firstterm> for
77 * lack of a better name. Several freedesktop.org specifications use
78 * key files now, e.g the
79 * <ulink url="http://freedesktop.org/Standards/desktop-entry-spec">Desktop
80 * Entry Specification</ulink> and the
81 * <ulink url="http://freedesktop.org/Standards/icon-theme-spec">Icon
82 * Theme Specification</ulink>.
84 * The syntax of key files is described in detail in the
85 * <ulink url="http://freedesktop.org/Standards/desktop-entry-spec">Desktop
86 * Entry Specification</ulink>, 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> where
121 * <literal>COUNTRY</literal> and <literal>MODIFIER</literal> are optional.
122 * Space before and after the '=' character are ignored. Newline, tab,
123 * carriage return and backslash characters in value are escaped as \n,
124 * \t, \r, and \\, respectively. To preserve leading spaces in values,
125 * these can also be escaped as \s.
127 * Key files can store strings (possibly with localized variants), integers,
128 * booleans and lists of these. Lists are separated by a separator character,
129 * typically ';' or ','. To use the list separator character in a value in
130 * a list, it has to be escaped by prefixing it with a backslash.
132 * This syntax is obviously inspired by the .ini files commonly met
133 * on Windows, but there are some important differences:
135 * <listitem>.ini files use the ';' character to begin comments,
136 * key files use the '#' character.</listitem>
137 * <listitem>Key files do not allow for ungrouped keys meaning only
138 * comments can precede the first group.</listitem>
139 * <listitem>Key files are always encoded in UTF-8.</listitem>
140 * <listitem>Key and Group names are case-sensitive. For example, a
141 * group called <literal>[GROUP]</literal> is a different from
142 * <literal>[group]</literal>.</listitem>
143 * <listitem>.ini files don't have a strongly typed boolean entry type,
144 * they only have GetProfileInt(). In key files, only
145 * <literal>true</literal> and <literal>false</literal> (in lower case)
146 * are allowed.</listitem>
149 * Note that in contrast to the
150 * <ulink url="http://freedesktop.org/Standards/desktop-entry-spec">Desktop
151 * Entry Specification</ulink>, groups in key files may contain the same
152 * key multiple times; the last entry wins. Key files may also contain
153 * multiple groups with the same name; they are merged together.
154 * Another difference is that keys and group names in key files are not
155 * restricted to ASCII characters.
161 * Error domain for key file parsing. Errors in this domain will
162 * be from the #GKeyFileError enumeration.
164 * See #GError for information on error domains.
169 * @G_KEY_FILE_ERROR_UNKNOWN_ENCODING: the text being parsed was in
170 * an unknown encoding
171 * @G_KEY_FILE_ERROR_PARSE: document was ill-formed
172 * @G_KEY_FILE_ERROR_NOT_FOUND: the file was not found
173 * @G_KEY_FILE_ERROR_KEY_NOT_FOUND: a requested key was not found
174 * @G_KEY_FILE_ERROR_GROUP_NOT_FOUND: a requested group was not found
175 * @G_KEY_FILE_ERROR_INVALID_VALUE: a value could not be parsed
177 * Error codes returned by key file parsing.
182 * @G_KEY_FILE_NONE: No flags, default behaviour
183 * @G_KEY_FILE_KEEP_COMMENTS: Use this flag if you plan to write the
184 * (possibly modified) contents of the key file back to a file;
185 * otherwise all comments will be lost when the key file is
187 * @G_KEY_FILE_KEEP_TRANSLATIONS: Use this flag if you plan to write the
188 * (possibly modified) contents of the key file back to a file;
189 * otherwise only the translations for the current language will be
192 * Flags which influence the parsing.
