Detailed Description

Manipulating the include paths in a context.

The include paths are the file-system paths that are searched when an include statement is encountered during keymap compilation.

The default include paths are, in that lookup order:

• The path $XDG_CONFIG_HOME/xkb, with the usual XDG_CONFIG_HOME fallback to $HOME/.config/ if unset.
• The path $HOME/.xkb, where $HOME is the value of the environment variable HOME.
• The XKB_CONFIG_EXTRA_PATH environment variable, if defined, otherwise the system configuration directory, defined at library configuration time (usually /etc/xkb).
• The XKB_CONFIG_ROOT environment variable, if defined, otherwise the system XKB root, defined at library configuration time.

Function Documentation

xkb_context_include_path_append()

XKB_EXPORT int xkb_context_include_path_append	(	struct xkb_context *	context,
		const char *	path
	)

Append a new entry to the context's include path.

Returns

1 on success, or 0 if the include path could not be added or is inaccessible.

xkb_context_include_path_append_default()

XKB_EXPORT int xkb_context_include_path_append_default

(

struct xkb_context *

context

)

Append the default include paths to the context's include path.

Returns

1 on success, or 0 if the primary include path could not be added.

xkb_context_include_path_reset_defaults()

XKB_EXPORT int xkb_context_include_path_reset_defaults

(

struct xkb_context *

context

)

Reset the context's include path to the default.

Removes all entries from the context's include path, and inserts the default paths.

Returns

1 on success, or 0 if the primary include path could not be added.

xkb_context_include_path_get()

XKB_EXPORT const char * xkb_context_include_path_get	(	struct xkb_context *	context,
		unsigned int	index
	)

Get a specific include path from the context's include path.

Returns

The include path at the specified index. If the index is invalid, returns NULL.
