gimpenv

gimpenv — Functions to access the GIMP environment.

Description

A set of functions to find the locations of GIMP's data directories and configuration files.

Functions

gimp_env_init ()

void
gimp_env_init (gboolean plug_in);

You don't need to care about this function. It is being called for you automatically (by means of the MAIN() macro that every plug-in runs). Calling it again will cause a fatal error.

Parameters

plug_in

must be TRUE if this function is called from a plug-in

 

Since: 2.4


gimp_directory ()

const gchar *
gimp_directory (void);

Returns the user-specific GIMP settings directory. If the environment variable GIMP2_DIRECTORY exists, it is used. If it is an absolute path, it is used as is. If it is a relative path, it is taken to be a subdirectory of the home directory. If it is a relative path, and no home directory can be determined, it is taken to be a subdirectory of gimp_data_directory().

The usual case is that no GIMP2_DIRECTORY environment variable exists, and then we use the GIMPDIR subdirectory of the local configuration directory:

  • UNIX: $XDG_CONFIG_HOME (defaults to $HOME/.config/)

  • Windows: CSIDL_APPDATA

  • OSX (UNIX exception): the Application Support Directory.

If neither the configuration nor home directory exist, g_get_user_config_dir() will return {tmp}/{user_name}/.config/ where the temporary directory {tmp} and the {user_name} are determined according to platform rules.

In any case, we always return some non-empty string, whether it corresponds to an existing directory or not.

In config files such as gimprc, the string ${gimp_dir} expands to this directory.

The returned string is owned by GIMP and must not be modified or freed. The returned string is in the encoding used for filenames by GLib, which isn't necessarily UTF-8 (on Windows it is always UTF-8.)

Returns

The user-specific GIMP settings directory.


gimp_installation_directory ()

const gchar *
gimp_installation_directory (void);

Returns the top installation directory of GIMP. On Unix the compile-time defined installation prefix is used. On Windows, the installation directory as deduced from the executable's full filename is used. On OSX we ask [NSBundle mainBundle] for the resource path to check if GIMP is part of a relocatable bundle.

In config files such as gimprc, the string ${gimp_installation_dir} expands to this directory.

The returned string is owned by GIMP and must not be modified or freed. The returned string is in the encoding used for filenames by GLib, which isn't necessarily UTF-8. (On Windows it always is UTF-8.)

Returns

The toplevel installation directory of GIMP.

Since: 2.8


gimp_data_directory ()

const gchar *
gimp_data_directory (void);

Returns the default top directory for GIMP data. If the environment variable GIMP2_DATADIR exists, that is used. It should be an absolute pathname. Otherwise, on Unix the compile-time defined directory is used. On Windows, the installation directory as deduced from the executable's full filename is used.

Note that the actual directories used for GIMP data files can be overridden by the user in the preferences dialog.

In config files such as gimprc, the string ${gimp_data_dir} expands to this directory.

The returned string is owned by GIMP and must not be modified or freed. The returned string is in the encoding used for filenames by GLib, which isn't necessarily UTF-8. (On Windows it always is UTF-8.)

Returns

The top directory for GIMP data.


gimp_locale_directory ()

const gchar *
gimp_locale_directory (void);

Returns the top directory for GIMP locale files. If the environment variable GIMP2_LOCALEDIR exists, that is used. It should be an absolute pathname. Otherwise, on Unix the compile-time defined directory is used. On Windows, the installation directory as deduced from the executable's full filename is used.

The returned string is owned by GIMP and must not be modified or freed. The returned string is in the encoding used for filenames by the C library, which isn't necessarily UTF-8. (On Windows, unlike the other similar functions here, the return value from this function is in the system codepage, never in UTF-8. It can thus be passed directly to the bindtextdomain() function from libintl which does not handle UTF-8.)

Returns

The top directory for GIMP locale files.


gimp_plug_in_directory ()

const gchar *
gimp_plug_in_directory (void);

Returns the default top directory for GIMP plug-ins and modules. If the environment variable GIMP2_PLUGINDIR exists, that is used. It should be an absolute pathname. Otherwise, on Unix the compile-time defined directory is used. On Windows, the installation directory as deduced from the executable's full filename is used.

Note that the actual directories used for GIMP plug-ins and modules can be overridden by the user in the preferences dialog.

In config files such as gimprc, the string ${gimp_plug_in_dir} expands to this directory.

The returned string is owned by GIMP and must not be modified or freed. The returned string is in the encoding used for filenames by GLib, which isn't necessarily UTF-8. (On Windows it always is UTF-8.)

Returns

The top directory for GIMP plug_ins and modules.


gimp_sysconf_directory ()

const gchar *
gimp_sysconf_directory (void);

Returns the top directory for GIMP config files. If the environment variable GIMP2_SYSCONFDIR exists, that is used. It should be an absolute pathname. Otherwise, on Unix the compile-time defined directory is used. On Windows, the installation directory as deduced from the executable's full filename is used.

In config files such as gimprc, the string ${gimp_sysconf_dir} expands to this directory.

The returned string is owned by GIMP and must not be modified or freed. The returned string is in the encoding used for filenames by GLib, which isn't necessarily UTF-8. (On Windows it always is UTF-8.).

Returns

The top directory for GIMP config files.


gimp_cache_directory ()

const gchar *
gimp_cache_directory (void);

Returns the default top directory for GIMP cached files. If the environment variable GIMP2_CACHEDIR exists, that is used. It should be an absolute pathname. Otherwise, a subdirectory of the directory returned by g_get_user_cache_dir() is used.

Note that the actual directories used for GIMP caches files can be overridden by the user in the preferences dialog.

In config files such as gimprc, the string ${gimp_cache_dir} expands to this directory.

The returned string is owned by GIMP and must not be modified or freed. The returned string is in the encoding used for filenames by GLib, which isn't necessarily UTF-8. (On Windows it always is UTF-8.).

Returns

The default top directory for GIMP cached files.

Since: 2.10.10


gimp_temp_directory ()

const gchar *
gimp_temp_directory (void);

Returns the default top directory for GIMP temporary files. If the environment variable GIMP2_TEMPDIR exists, that is used. It should be an absolute pathname. Otherwise, a subdirectory of the directory returned by g_get_tmp_dir() is used.

In config files such as gimprc, the string ${gimp_temp_dir} expands to this directory.

Note that the actual directories used for GIMP temporary files can be overridden by the user in the preferences dialog.

The returned string is owned by GIMP and must not be modified or freed. The returned string is in the encoding used for filenames by GLib, which isn't necessarily UTF-8. (On Windows it always is UTF-8.).

Returns

The default top directory for GIMP temporary files.
