Snackwrap

After changing a file, run a command.

Let's say I want to run a build script every time I save a file in src/. I also want to scream every time you edit a forbidden file.

I'll make snackwrap.txt:

src/*           ./build.sh
forbidden.txt   echo "AUUUGHH!!"

Now, I run Snackwrap.

$ snackwrap

Now, every time I change a file in src/, I'll run build.sh. And every time I edit forbidden.txt, I'll scream.

You can run Snackwrap in a few ways:

$ python snackwrap.py
$ ./snackwrap.py
$ # put snackwrap.py somewhere in your PATH and type snackwrap

For more help:

$ snackwrap -h
