NAME

prefix.eclass - Eclass to provide Prefix functionality

DESCRIPTION

Gentoo Prefix allows users to install into a self defined offset located somewhere in the filesystem. Prefix ebuilds require additional functions and variables which are defined by this eclass.

FUNCTIONS

eprefixify <list of to be eprefixified files>

replaces @GENTOO_PORTAGE_EPREFIX@ with ${EPREFIX} for the given files, dies if no arguments are given, a file does not exist, or changing a file failed.

hprefixify [ -w <line match> ] [ -e <extended regex> ] [ -q <quotation char> ] <list of files>

Tries a set of heuristics to prefixify the given files. Dies if no arguments are given, a file does not exist, or changing a file failed.

Additional extended regular expression can be passed by -e or environment variable PREFIX_EXTRA_REGEX. The default heuristics can be constrained to lines that match a sed expression passed by -w or environment variable PREFIX_LINE_MATCH. Quotation characters can be specified by -q or environment variable PREFIX_QUOTE_CHAR, unless EPREFIX is empty.

prefixify_ro <file>

prefixify a read-only file. copies the files to ${T}, prefixies it, echos the new file.

ECLASS VARIABLES

EPREFIX: The offset prefix of a Gentoo Prefix installation. When Gentoo Prefix is not used, ${EPREFIX} should be "". Prefix Portage sets EPREFIX, hence this eclass has nothing to do here in that case. Note that setting EPREFIX in the environment with Prefix Portage sets Portage into cross-prefix mode.
