A source file watcher for Bazel projects

Ever wanted to save a file and have your tests automatically run? How about restart your webserver when one of the source files change? Look no further.

Compile the //ibazel target inside this repo and copy the source file onto your $PATH.

Then:

# ibazel build //path/to/my:target

Hack hack hack. Save and your target will be rebuilt.

Right now this repo supports build, test, and run.

Additional notes

What about the --watchfs flag?

Bazel has a flag called --watchfs which, according to the bazel command-line help does:

If true, Bazel tries to use the operating system's file watch service for local changes instead of scanning every file for a change

Unfortunately, this option does not rebuild the project on save like the Bazel watcher does, but instead queries the file system for a list of files that have been invalidated since last build and will require reinspection by the Bazel server.
