make-pipe

Makes pipes easier to use in makefiles by quitting and returning a nonzero exit status if any of the constituent commands return nonzero.

Usage

Replace where you'd put a pipe with a string containing only the pipe character.

make-pipe echo 'heya' '|' cat '|' grep -Eo '[ea]'
# outputs:
# e
# a

If you want to pipe data into make-pipe, set the environment variable LISTEN. This can be useful for handing off a pipeline you don't control into your own pipeline which will fail if any of its constituent commands fails.

echo hey | LISTEN=y make-pipe cat '|' cat
# outputs:
# hey

Install

npm install -g make-pipe
