Option to hide transitive dependencies

[ssokolow]

Since my main use for cargo-feature-set is to inspect which features I may be able to turn off to speed up my builds, it'd be nice to have an option to show only crates listed directly in my Cargo.toml.

That way, I could get a listing of only the features I can actually turn off without patching dependencies.

That's what -R / --root-deps-only gets you already.

Has that not been released yet? I cargo install'd cargo-feature-set just before opening that feature request and this is what --help looks like:

cargo-feature-set 0.4.0
Extract the features for every compiled crate from `cargo metadata`

USAGE:
    feature-set [OPTIONS]

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
        --features <features>...           Space-separated list of features to activate
        --manifest-path <manifest-path>    Path to Cargo.toml

That could be it. I can do a release in a bit.

0.5.0 is out

[ssokolow]

Thanks. :)

Is it supposed to only list the enabled features with no option to list available features? ...because that's how it appears to be working and the README is unclear on that point.

(If I only have one choice, enabled is more useful, but it'd be nice to have the option of listing all available choices.)

[badboy]

Yes, it's only for features enabled in that invocation of the build (and it might be imprecise, thanks to build.rs, etc.).
If you need a list of all available features then I'm afraid you have to build that yourself.

[ssokolow]

That's OK. I was just wondering. If I need a list of all available features, I can probably hack together a little script using PyTOML.

(5 minutes on the code to extract features from a list of Cargo.toml files, 15 to 50 minutes looking up the proper way to obey the configuration for where a Cargo install is configured to cache downloaded dependency sources.)
