[Caml-list] [ANN] dune_watch, a small tool to relaunch jbuilder build at file system updates

[Jun Furuse]

Hi,

I wrote a small tool, dune_watch, which automatically executes
jbuilder build command each time when files under the executed
directory are updated.  This is something similar to the polling mode
of omake's -P option, which I miss most in jbuilder.

dune_watch uses fswatch command to monitor the file system.  Since
dune_watch knows nothing of the build dependencies, it may launch
jbuilder even when it is not really required. It is, however, very
useful for me, until jbuilder itself will support the file system
polling.

dune_watch will be opam-available soon.

Regards,
Jun

I've been using a small script for the same purpose for a while now (as
a Makefile target):

watch:
	while find src/ -print0 | xargs -0 inotifywait -e delete_self -e modify ; do \
        jbuilder build @install; \
	done

I found watchman (https://facebook.github.io/watchman/) to be useful
in this kind of situation.
