This reminds me that I used this when I was messing
with patchfs for midnight commander. For those who
don't know it's REALLY easy to create virtual filesystems
for midnight commander. Ones that exist already are
ftp/tar/rpm/deb/.. and I created this one for browsing
into patch files (in unified format):
####### snip ########
#! /bin/sh
export LC_ALL=C
patchfs_list ()
{
date=`date +"%b %d %H:%M"`
perm="-r--r--r--"
uid=00000000
gid=00000000
size=00000000
nlink=" 1"
echo "$perm $nlink $uid $gid $size $date SUMMARY"
$cat $1 |
sed -n "s/^+++ \([^ ]*\).*/$perm $nlink $uid $gid $size $date \1/gp"
}
patchfs_copyout ()
{
if [ "$2" = SUMMARY ]; then # list of all affected files
if diffstat -V >/dev/null 2>&1; then
$cat $1 | diffstat 2>/dev/null > $3
else
sed -n "s/^+++ \([^ ]*\).*/\1/gp" > $3
fi
exit 0
fi
fn=`echo $2 | sed 's|/|\\\/|g'` # escape '/' in filename
$cat $1 |
sed -e '/^diff /d' |
sed -ne "/^+++ .*$fn/,/^--- /{
/^--- /d
p
}" > $3
}
type=`file $2`
case $type in
*bzip*) cat="bzip2 -dc" ;;
*gzip*) cat="gzip -dc" ;;
*text*) cat="cat" ;;
*) exit 1
esac
umask 077
case "$1" in
list) patchfs_list $2; exit 0;;
copyout) patchfs_copyout $2 $3 $4; exit 0;;
run) exit 0;;
esac
exit 1
####### snip ########
You need to copy this to or overwrite /usr/lib/mc/extfs/patchfs,
and for all users to be able to use this automatically you
will need to edit /usr/lib/mc/mc.ext and before ### Archives ### add:
# Patches
regex/\.(patch|diff)\.*(gz|bz2)*$
Open=%cd %p#patchfs
you will also need to do the same in your ~/.mc/ini file if it exits.
In summary all you need to do when this is set up is to browse to
a directory containing (compressed) patch files (*.diff or *.patch),
and hit return on the file, and you can view bits/stats of the patch
with F3.
It really is worth investing the 15 minutes required to learn mc.
It is so powerful, and nicely integrates with the unix environment
as illustrated above.
Padraig.
