# $NetBSD: bsd.pkg.extract.mk,v 1.21 2006/01/23 14:43:50 rillig Exp $
#
# This Makefile fragment is included to bsd.pkg.mk and defines the
# relevant variables and targets for the "extract" phase.
#
# The following variables may be set by the package Makefile and
# specify how extraction happens:
#
# EXTRACT_ONLY is a list of distfiles relative to ${_DISTDIR} to
# extract and defaults to ${DISTFILES}.
#
# EXTRACT_SUFX is the suffix for the default distfile to be
# extracted. The default suffix is ".tar.gz".
#
# EXTRACT_CMD is a shell command list that extracts the contents of
# an archive named by the variable ${DOWNLOADED_DISTFILE} to the
# current working directory. The default is ${EXTRACT_CMD_DEFAULT}.
#
# EXTRACT_CMD_DEFAULT uses the "extract" script to unpack archives. The
# precise manner in which extraction occurs may be tweaked by setting
# EXTRACT_OPTS, EXTRACT_USING and EXTRACT_ELEMENTS.
#
# EXTRACT_OPTS is a list of options to pass to the "extract" script
# when using EXTRACT_CMD_DEFAULT. See the comments at the head of
# the "extract" script for a definitive list of the available
# options. The default list is empty.
#
# EXTRACT_USING specifies the tool used to extract tar/ustar-format
# archives when using EXTRACT_CMD_DEFAULT. The possible values are
# "gtar", "nbtar", and "pax". By default, we use the "nbtar" tool
# (pkgsrc's pax-as-tar).
#
# EXTRACT_ELEMENTS is a list of files within the distfile to extract
# when using EXTRACT_CMD_DEFAULT. By default, this is empty, which
# causes all files within the archive to be extracted.
#
# The following are read-only variables that may be used within a package
# Makefile:
#
# DOWNLOADED_DISTFILE represents the path to the distfile that is
# currently being extracted, and may be used in custom EXTRACT_CMD
# overrides, e.g.
#
# EXTRACT_CMD= ${TAIL} +25 ${DOWNLOADED_DISTFILE} > foo.pl
#
# The following targets are defined by bsd.pkg.extract.mk:
#
# extract is the target that is invoked by the user to perform
# extraction.
#
# do-extract is the target that causes the actual extraction of
# the distfiles to occur during the "extract" phase. This target
# may be overridden in a package Makefile.
#
# {pre,post}-extract are the targets that are invoked before and after
# do-extract, and may be overridden in a package Makefile.
#
EXTRACT_ONLY?= ${DISTFILES}
EXTRACT_SUFX?= .tar.gz
EXTRACT_USING?= nbtar
EXTRACT_ELEMENTS?= # empty

### Discover which tools we need based on the file extensions of the
### distfiles.
