Software development often involves running the same commands over and over. Boring! Watchexec is a simple, standalone tool that watches a path and runs a command whenever it detects modifications. Install it today with cargo-binstall watchexec-cli, from the binaries below, find it in your favourite package manager, or build it from source with cargo install watchexec-cli.

In this release:

  • New: start/stop messages are now in colour. Use --colour=never (--color also accepted) to disable, or the conventional always and auto. (#144, #237, #698)
  • New: --timings to print how long the command took. (#278, #698)
  • New: --quiet to disable printing any message (except warning and error logs). (#698)
  • New: --bell to ring the terminal bell on command end. (#238, #698)
  • New: --ignore-nothing to switch on all the --no-*-ignore flags. (#275, #625, #695)
  • New: --only-emit-events disables launching a command, and only prints events to stdout. Requires --emit-events-to to specify the format to print. This lets you obtain a stream of change events to handle directly rather than mediating via a command. (#676, #691)
  • New: --map-signal to map signals received by Watchexec to other signals sent to the command. (#151, #387, #710)
  • Change: --emit-events-to stdin and json-stdin modes are renamed to stdio and json-stdio respectively; the old names are aliased to preserve compatibility.

Other changes:

  • Uses the Watchexec library 3.0. (#601)
  • -w /dev/null disables watching any files. This is the literal string /dev/null, it won't detect the null device via links or fifos. (#601)
  • Running as PID1 (e.g. in Docker) is fully supported. (#140, #601, #624)
  • Performance improvements and bugfixes around reaping processes (via command-group 5). (#601)
  • Performance improvements and bugfixes around watching files (via notify 6). (#601)
  • Clear the screen before printing events, so --print-events and --clear can meaningfully be used together. (#601)
  • Hint that more or less help is available with long --help and short -h flags. (#601)
  • The PDF version of the manual page is gone, due to the tooling I used disappearing, and the general ugliness of its typesetting. (#710)
