A fantastic crate is cargo watch, which allows, for example, for you to execute:
cargo watch -x run
to automatically rebuild/run on src change. This is amazing for development but one issue I have is that it seems to not support the --manifest-path argument that can be used with cargo run to explicitly specify the path to the .toml file of the project such that it can be run from a different pwd than the Cargo.toml file itself:
cargo run --manifest-path /home/user/project/Cargo.toml
The crate documentation doesn't mention anything about this, so I was wondering if anyone who uses this crate has found a way around this. When attempting to use the --manifest-path argument I receive:
error: Found argument '--manifest-path' which wasn't expected, or isn't valid in this context
USAGE:
cargo watch [FLAGS] [OPTIONS]
Which makes some sense as I know not all commands support the --manifest-path arg, but since the crate uses cargo run to run the project itself I'm guessing there is some way around this without using e.g. sh -c 'cd [path to .toml file] && cargo watch -x run'
Yes you can just use the invocation which lets you run arbitrary commands:
cargo watch -- cargo run --manifest-path=path/to/Cargo.toml
