I think it is a good idea, and it may even deserve to eventually become
the default behavior as it is on OpenBSD.
OpenBSD uses a variable EXTRACT_CASES to hold a shell fragment. You can
prepend cases to it in order to add to the default handlers or to
override them.
Some relevant snippet's from OpenBSD's bsd.port.mk are:
.if !empty(EXTRACT_ONLY:M*.zip)
_USE_ZIP?= Yes
.endif
.if !empty(EXTRACT_ONLY:M*.tar.bz2) || (defined(PATCHFILES) && !empty(_PATCHFILE
S:M*.bz2))
_USE_BZIP2?= Yes
.endif
_USE_ZIP?= No
_USE_BZIP2?= No
EXTRACT_CASES?=
.if ${_USE_ZIP:L} != "no"
BUILD_DEPENDS+= :unzip-*:archivers/unzip
EXTRACT_CASES+= *.zip) ${UNZIP} -q ${FULLDISTDIR}/$$archive -d ${WRKDIR};;
.endif
.if ${_USE_BZIP2:L} != "no"
BUILD_DEPENDS+= :bzip2-*:archivers/bzip2
EXTRACT_CASES+= *.tar.bz2) ${BZIP2} -dc ${FULLDISTDIR}/$$archive | ${TAR} xf -;;
.endif
EXTRACT_CASES+= *.tar) ${TAR} xf ${FULLDISTDIR}/$$archive;;
EXTRACT_CASES+= *.shar.gz|*.shar.Z|*.sh.gz|*.sh.Z) ${GZIP_CMD} -dc ${FULLDISTDIR}/$$archive | ${_PERL_FIX_SHAR} | /bin/sh;;
EXTRACT_CASES+= *.shar | *.sh) ${_PERL_FIX_SHAR} ${FULLDISTDIR}/$$archive | /bin/sh;;
EXTRACT_CASES+= *.tar.gz) ${GZIP_CMD} -dc ${FULLDISTDIR}/$$archive | ${TAR} xf - ;;
EXTRACT_CASES+= *.gz) ${GZIP_CMD} -dc ${FULLDISTDIR}/$$archive >`basename $$archive .gz`;;
EXTRACT_CASES+= *) ${GZIP_CMD} -dc ${FULLDISTDIR}/$$archive | ${TAR} xf -;;
...
[and for the action]
# What EXTRACT normally does:
@PATH=${PORTPATH}; set -e; cd ${WRKDIR}; \
for archive in ${EXTRACT_ONLY}; do \
case $$archive in \
${EXTRACT_CASES} \
esac; \
done
...
In a port Makefile you just use something like this:
...
MASTER_SITES= http://www.rdrop.com/users/billmc/
DISTFILES= adcomplain.pl.uu
EXTRACT_CASES= *.uu) uudecode ${FULLDISTDIR}/$$archive;;
...
There is also a similar PATCH_CASES.
