Add unstable --dep-coverage option #353

Closed taiki-e closed 3 months ago

taiki-e commented 3 months ago

By default, cargo-llvm-cov only shows coverage of crates in the workspace.

This can be disabled by --disable-default-ignore-filename-regex flag. However, in this case, coverage of crates and all dependencies in the workspace will be shown.

disable-default-ignore-filename-regex

If you specify a dependency with the --dep-coverage option that this PR adds, only the coverage of that dependency will be shown. The following is using --dep-coverage memchr:

dep-coverage

The option is currently marked as unstable due to limitations such as not yet being able to show coverage other than dependencies from crates.io.

Thank you very much! I was going to use a script for this, but I didn't expect to implement this feature so quickly!

there is a typo 

        --dep-coverage <NAME>
            Show coverage of th specified dependency instead of the crates in the current workspace. (unstable)
