cargo-watch

Cargo Watch is a tool to watch your Cargo-based project and run commands when files change. It focuses on the Rust development experience and aims to be flexible enough to suit most without becoming complicated to use. Install or upgrade it today with cargo binstall cargo-watch, or cargo install cargo-watch if you don't have Binstall yet.

In this release:

• Ignore rustc-ice-* logs by default (#277)

Cargo Watch is a tool to watch your Cargo-based project and run commands when files change. It focuses on the Rust development experience and aims to be flexible enough to suit most without becoming complicated to use. Install or upgrade it today with cargo binstall cargo-watch, or cargo install cargo-watch if you don't have Binstall yet.

In this release:

• Fix a critical bug where signals sent to commands (including the ones cargo watch would send!) would not be handled due to Rust 1.66 changing its behaviour. (#249, #247)

Other changes:

• Allow --use-shell=none when using a trailing command (not with -x or -s). Note that this requires the trailing command not be quoted in full.
• Add --no-process-group to disable using a process group for the command.
• Fix malformed output on Windows. (#244)

Future changes:

• Intent to remove: checksums and signatures (#238)
• Intent to remove: RPM and DEB packages (#238)

Comment on the issue above if this would affect you!

• Add --env-file option to read environment variables from file, like a .env. Note that .env files are not automatically loaded, you do need to provide the option. (#235, #236)
• Add -L, -E, --env-var to manpage and completions file. (#236)

• Fix Linux GNU builds for older debians (#234)

• Fix the top-level workspace directory not getting watched when it's a virtual workspace. (#226)

No code changes this release.

• 📦 You can now install from binary using cargo-binstall on Linux and macOS. Windows support will depend on binstall#37.
• 📜 For servers, the documentation now recommends systemfd over and above catflap.
• 🧑‍🤝‍🧑 The project now officially uses Caretaker Maintainership and a blurb about maintenance attitude had also been previously added last year. This may have implications for you, as a user, especially wrt supply chain issues. The commit message has more details.

• Log format (debugs and warnings) changed as part of the upgrade to watchexec 1.14
• WATCHEXEC_* environment variables are not set for subprocesses anymore. I didn't actually intend to have them in the first place, but chime in if you rely on them!
• #152 New --features option to pass the --features flag to a selection of cargo commands that support them. E.g. cargo watch --features feat -x check -x test can now be used instead of cargo watch -x 'check --features feat' -x 'test --features feat'.
• Also fixes a bug where a polling message was shown even when --quiet was given.

• #149: if watched directory didn't contain a .git folder, thread would block (infinite loop)
• Also, #BlackLivesMatter. Closer to home, #ArmsDownNZ (police here wants to arm up, fuck that). Over the pond, #AboriginalLivesMatter. #JunkTerrorBill a bit further away, and spare a thought for Hong Kong, which has been fighting since March last year! I'm not comfortable stating that on Watchexec (which I also maintain and is released concurrently) given it's not, originally, my project, but here I can.

• #147 (pulling in watchexec 1.13): now gitignores in subdirs are also honoured
• #137: MSRV is documented now, as well as the versioning policy when bumping MSRV

• Watchexec 1.12.0
• More documentation on ignore files (e4e13bee30016d5ee2babfe3d7f739fcaee07cc6)
• Bring in --no-ignore support from upstream (#133)
• Bring in --watch-when-idle support from upstream (329aa33f4ddcff5dbb1c291f69c1f7a8d7709025)
• FYI: https://github.com/watchexec/watchexec/pull/142 from upstream has improved --ignore handling!

From upstream watchexec: .ignore files are now supported.

• Fixed a crash on error due to an upstream bug.
• Allowed direct invocation without the watch argument, such that all these now do the same: (#114)

$ cargo watch
$ cargo-watch watch
$ cargo-watch # <== NEW!

• Fixed a bug on Windows where the wrong command separator was being used (#113)
• Added exit code to the finish message in windows, similar to unixes.

• No more quotes or escapes for the start/finish messages, fixing #112.
• The start message was brought into Rust code rather than shell, so quoting doesn't affect it anymore! This may help a few other issues (e.g. #107).
• The finish message is printed regardless of whether the command is successful or not.
• On unixes only for now, the exit status is now reported as part of the finish message.
• LTO and codegen optimisations are now enabled for release builds.

• #93 and #110 fixed through the Watchexec 1.10.0 release
