module Basedir

: sig

XDG Base Directory support, for locating caches, configuration, etc

type basedirs = {

# data	: Common.filepath list	;
# cache	: Common.filepath list	;
# config	: Common.filepath list	;

}

val get_default_config : Common.system -> basedirs

Get configuration using ZEROINSTALL_PORTABLE_BASE (if set), or the platform default, modified by any XDG_* variables which are set.

val load_first : Common.system -> Common.filepath -> Common.filepath list -> Common.filepath option

load_first system relpath search_path returns the first configuration path (base +/ relpath) that exists from the base paths in search_path.

val save_path : Common.system -> Common.filepath -> Common.filepath list -> Common.filepath

save_path system relpath search_path creates the directory List.hd search_path +/ relpath (and any missing parents) and returns its path.

val get_unix_home : Common.system -> Common.filepath

Get the home directory (normally $HOME). If we're running as root and $HOME isn't owned by root (e.g. under sudo) then return root's real home directory instead.
