Maintainerbot is designed to make it easy to create custom bots for interacting
with Github repositories. The core of Maintainerbot is maintner, a Go program
that creates an in-memory representation of your Github repository. Removing the
Github API (and the need to handle rate limits, and paging) is a great way to
make creating bots easy.
(maintner and gopherbot are written by the Go Authors, and available from
the golang.org/x/build package.)
Here's a bot that can check whether users have signed the CLA, against a list of usernames stored in a spreadsheet.
ctx, cancel := context.WithTimeout(context.Background(), 10*time.Millisecond)
defer cancel()
token := os.Getenv("GITHUB_TOKEN")
ghc := maintainerbot.NewGitHubClient(token, 0)
bot := maintainerbot.New("rails", "rails", token)
spreadsheetURL := "https://docs.google.com/spreadsheets/d/<key>/export?format=csv&sheet=0"
cla := tasks.NewCLAChecker(ghc, "http://example.com/sign-cla", tasks.NewSpreadsheetFetcher(spreadsheetURL))
cla.StartFetch(ctx)
bot.RegisterTask(cla)
bot.Run(ctx)Other task types are available in the tasks package.
go get -u github.com/sourcegraph/maintainerbot
