peat: Pete and Repeat are sitting on a fence. …

Here’s a simple python tool that jumps into action when a file changes: peat.


peat is built to execute a command of your choosing, and requires only a list of files to watch as input. As you can see above, probably its most basic use is just to send a message to the screen to announce a change.

But it seems capable of executing almost anything as its target, so you could set it to clean up files, compile a code snippet and run it, or … something completely different.

The syntax to get peat running can be a small challenge; by default peat wants a list separated by whitespace. Check the flags if you want to feed it a list separated by newlines or blank spaces.

I should also mention that in Arch, peat wouldn’t run without calling specifically for python2. On the other hand, it seemed to run without any oddball dependencies or bizarre python libraries, so it may be that it will run well on a vanilla system with no added weight.

I feel like I should mention the long list of file event watchers that are available, so it may be that using python as the basis for a file watcher is still too cumbersome.

And given that their list of features is as wide and long as the list itself, the choice becomes a little more academic. peat is worth investigating if you are comfortable with python and if its advanced handling doesn’t intimidate you. But remember there are many others in the running.
