import ""

Package Files



const Server = ""

Server is the Go project's production maintner log.

func Dir Uses

func Dir() string

Dir returns the directory containing the cached mutation logs.

func Get Uses

func Get(ctx context.Context) (*maintner.Corpus, error)

Get returns the Go project's corpus, containing all Git commits, Github activity, and Gerrit activity and metadata since the beginning of the project.

Use Corpus.Update to keep the corpus up-to-date. If you do this, you must hold the read lock if reading and updating concurrently.

The initial call to Get will download approximately 350-400 MB of data into a directory "golang-maintner" under your operating system's user cache directory. Subsequent calls will only download what's changed since the previous call.

Even with all the data already cached on local disk, a call to Get takes approximately 5 seconds to read the mutation log into memory. For daemons, use Corpus.Update to incrementally update an already-loaded Corpus.

The in-memory representation is about 25% larger than its on-disk size. It's currently under 500 MB.

See for how to walk the data structure. Enjoy.


corpus, err := godata.Get(context.Background())
if err != nil {
num := 0
corpus.GitHub().ForeachRepo(func(gr *maintner.GitHubRepo) error {
    return gr.ForeachIssue(func(gi *maintner.GitHubIssue) error {
        return gi.ForeachComment(func(*maintner.GitHubComment) error {
            return nil
fmt.Printf("%d GitHub comments on Go repos.\n", num)

func XdgCacheDir Uses

func XdgCacheDir() string

XdgCacheDir returns the XDG Base Directory Specification cache directory.
