WWHRD? (What Would Henry Rollins Do?) Github Actions codecov

WWHRD?

Have Henry Rollins check vendored licenses in your Go project.

Please note that wwhrd only checks packages stored under vendor/, if you are using Go modules (go mod), you can add go mod vendor before running wwhrd, this will dump a copy of the vendored packages inside the local repo.

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 compatible with Anderson, just run wwhrd check -f .anderson.yml.

---
denylist:
  - GPL-2.0

allowlist:
  - Apache-2.0
  - MIT

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

Having a license in the denylist 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!

Generate a dependency graph

Starting from version v0.3.0, wwhrd graph can be used to generate a graph in DOT language, the graph can then be parsed by Graphviz or other compatible tools.

To generate a PNG of the dependencies of your repository, you can run:

$ wwhrd graph -o - | dot -Tpng > wwhrd-graph.png

The -o - option will print the DOT output to STDOUT.

Usage

$ wwhrd
Usage:
  wwhrd [OPTIONS] <check | graph | list>
