Create a wrapper script which calls the first printer program and pipes
its output to the second filter program (which has its stdout connected
to that of the script interpreter and then specify the script as a
filter instead of the original one.
In the simplest case, if you have
*.c filter=rcs-keywords
[filter "rcs-keywords"]
clean = rcs-remove
smudge = rcs-expand
You could then write a shell script
#!/bin/sh
set -e -u
usage(fd) {
echo 'Usage: myscript {clean|smudge}'
}
if [ $# -ne 1 ];
usage >&2
exit 1
fi
case "$1" in
clean)
myfilter -clean | rcs-remove
;;
smudge)
rcs-expand | myfilter -smudge
;;
help)
usage
exit 0
;;
*)
usage >&2
exit 1
;;
esac
And then change the definition in .gitattributes:
*.c filter=complex
[filter "complex"]
clean = ~/bin/complex-git-filter clean
smudge = ~/bin/complex-git-filter smudge
