delta: A library for detecting file changes
Delta is a library for detecting file changes in any given directory. The package is written using the sodium FRP library but it also provides a callback based API.
File changes on OS X are based on the
FSEvents API that is also
used by TimeMachine. On other operating systems the library
currently uses recursive descents in directories. I will include
inotify for Linux. If someone would like to have a non-polling
based API for windows or BSD, I would really like it if anyone
The project also contains an executable, delta-run, which allows you to run arbitrary shell commands when a file in a directory (recursively) changes.
$> delta-run --help Usage: delta-run [-i|--interval INTERVAL] [-v|--verbose] FILE CMD Available options: -h,--help Show this help text -i,--interval INTERVAL Run at most every n seconds -v,--verbose Print extra output FILE The directory that is watched CMD The command to run
For example you could use
delta-run to rebuild your project
everytime the source changes like this:
delta-run ./src "cabal build"
Build in FSEvents support (OS X)
Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info

Note: This package has metadata revisions in the cabal description newer than included in the tarball. To unpack the package including the revisions, use 'cabal get'.
