Show what Dune watches via inotify

Success, waiting for filesystem changes...

The pattern below excludes absolute files as Dune currently watches
|
||
|
|
everything in the PATH, which is not very reproducible.
|
||
|
|
|
||
|
|
$ sed -nE 's/inotify_add_watch\([0-9]*, "([^/].*)", .*\) (=.*)/watch \1 \2/p' ../log | sort -u
|
||
|
|
watch . = 2
|
||
|
|
watch _build/.sync = 1
|
||
|
|
watch src = 3
|
||
|
|
|
||
|
|
Since the pattern above is not reproducible, uncomment the next lines
|
||
|
|
to see what it is really doing
|
||
|
|
# $ sed -nE 's/inotify_add_watch\([0-9]*, "(.*)", .*\) (=.*)/watch \1 \2/p' ../log | sort -u -k4n -k2 | sed "s,$OPAM_SWITCH_PREFIX,OPAM_SWITCH_PREFIX," | sed "s,$DUNE_SOURCEROOT,DUNE_SOURCEROOT,"
|
||
|
|
# watch _build/.sync = 1
|
||
|
|
# watch . = 2
|
||
|
|
# watch src = 3
|
||
|
|
# watch DUNE_SOURCEROOT/_build/default/test/blackbox-tests/test-cases/.bin = 4
|
||
|
|
# watch DUNE_SOURCEROOT/_build/install/default/bin = 5
|

# watch OPAM_SWITCH_PREFIX/bin = 6
