Description

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 and the Icon Theme Specification.

The syntax of key files is described in detail in the Desktop Entry Specification, 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]=Bonjour
Welcome[it]=Ciao

[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. Space before and after the '=' character are ignored. Newline, tab, carriage return and backslash characters are escaped as \n, \t, \r, and \\, respectively. To preserve initial and final spaces, 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 allow only comments before 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 group from [group].

Details

GKeyFile

typedef struct _GKeyFile GKeyFile;

The GKeyFile struct contains only private fields and should not be used directly.


G_KEY_FILE_ERROR

#define G_KEY_FILE_ERROR g_key_file_error_quark()

Error domain for key file parsing. Errors in this domain will be from the GKeyFileError enumeration. See GError for information on error domains.


enum GKeyFileError

typedef enum
{
  G_KEY_FILE_ERROR_UNKNOWN_ENCODING,
  G_KEY_FILE_ERROR_PARSE,
  G_KEY_FILE_ERROR_NOT_FOUND,
  G_KEY_FILE_ERROR_KEY_NOT_FOUND,
  G_KEY_FILE_ERROR_GROUP_NOT_FOUND,
  G_KEY_FILE_ERROR_INVALID_VALUE
} GKeyFileError;

Error codes returned by key file parsing.

G_KEY_FILE_ERROR_UNKNOWN_ENCODINGthe text being parsed was in an unknown encoding
G_KEY_FILE_ERROR_PARSEdocument was ill-formed
G_KEY_FILE_ERROR_NOT_FOUNDthe file was not found
G_KEY_FILE_ERROR_KEY_NOT_FOUNDa requested key was not found
G_KEY_FILE_ERROR_GROUP_NOT_FOUNDa requested group was not found
G_KEY_FILE_ERROR_INVALID_VALUEa value could not be parsed

enum GKeyFileFlags

typedef enum
{
  G_KEY_FILE_NONE              = 0,
  G_KEY_FILE_KEEP_COMMENTS     = 1 << 0,
  G_KEY_FILE_KEEP_TRANSLATIONS = 1 << 1
} GKeyFileFlags;

Flags which influence the parsing.

G_KEY_FILE_NONENo flags, default behaviour
G_KEY_FILE_KEEP_COMMENTSUse this flag if you plan to write the (possibly modified) contents of the key file back to a file; otherwise all comments will be lost when the key file is written back.
G_KEY_FILE_KEEP_TRANSLATIONSUse this flag if you plan to write the (possibly modified) contents of the key file back to a file; otherwise only the translations for the current language will be written back.

g_key_file_new ()

GKeyFile*   g_key_file_new                  (void);

Creates a new empty GKeyFile object. Use g_key_file_load_from_file(), g_key_file_load_from_data() or g_key_file_load_from_data_dirs() to read an existing key file.

Returns : an empty GKeyFile.

Since 2.6


g_key_file_free ()

void        g_key_file_free                 (GKeyFile *key_file);

Frees a GKeyFile.

key_file : a GKeyFile

Since 2.6


g_key_file_set_list_separator ()
