WWHRD? (What Would Henry Rollins Do?)

Have Henry Rollins check vendored licenses in your Go project.

Please note that wwhrd only checks packages stored under vendor/.

Installation

$ go get -u github.com/frapposelli/wwhrd

Using Brew on macOS:

$ brew install frapposelli/tap/wwhrd

Configuration file

Configuration for wwhrd is stored in .wwhrd.yml at the root of the repo you want to check.

The format is borrowed from Anderson and it's 1:1 compatible (just run wwhrd check -f .anderson.yml).

---
blacklist:
  - GPL-2.0

whitelist:
  - Apache-2.0
  - MIT

exceptions:
  - github.com/jessevdk/go-flags
  - github.com/pmezard/go-difflib/difflib

Having a license in the blacklist section will fail the check, unless the package is listed under exceptions.

exceptions can also be listed as wildcards:

exceptions:
  - github.com/davecgh/go-spew/spew/...

Will make a blanket exception for all the packages under github.com/davecgh/go-spew/spew.

Use it in your CI!
