Help message is slightly messed up

[ckaran]

Running cargo help release yields the following (abbreviated):

$ cargo help release
cargo-release-release 0.13.4
Cargo flags for selecting crates in a workspace

USAGE:
    cargo-release release [OPTIONS] [--] [level-or-version]

Normally, we use this tool as cargo release, even though cargo-release should be in the path. cargo-release-release is not in my path, so I suspect that there is a bug there.

[sunng87]

This is a minor issue with the cli parser we use. Are you interested in investigation and making a PR for this?

[ckaran]

@sunng87 I wish I had the time to, but I can't. I'm sorry.

The help string is coming from clap-cargo, we could workaround it in clap-cargo like we did in clap-verbosity-flag, see clap-rs/clap-verbosity-flag#21

The underlying structopt bug is TeXitoi/structopt#333

[epage]

New clap-cargo released. Give it a try!

[ckaran]

@epage Just pull the latest (14ecbe336ae1ed7205b4a7f5f4f9783b76b132d5), and this is what I get:

$ cargo run --release -- release --help
    Finished release [optimized] target(s) in 0.06s
     Running `target/release/cargo-release release --help`
cargo-release-release 0.13.5-alpha.0

USAGE:
    cargo-release release [OPTIONS] [--] [level-or-version]

Would I see something different if this were installed rather than run from the command line?

[epage]

With the latest clap-cargo it is left to cargo-release

• cargo-release --help is handled by Command which doesn't have a help string: https://github.com/sunng87/cargo-release/blob/master/src/main.rs#L1029
• cargo-release release --help is handled by ReleaseOpt which also doesn't have a help string: https://github.com/sunng87/cargo-release/blob/master/src/main.rs#L830

but at least it isn't saying "Cargo flags for selecting crates in a workspace"
