Package file naming convention

[bcomnes]

package file names (often) line up with with the name of a public export of the package
archive/tar has no tar/tar.go, but tar.NewWriter/tar.Writer comes out of tar/writer.go for example (edited)

i’d just pick at stblib packages if you want examples of the way to do it
https://github.com/golang/go/tree/master/src/bytes has bytes.go
https://github.com/golang/go/tree/master/src/archive/tar has no tar.go
no package has a file that contains all exports with other files that are only internal
