Go Outline

Simple utility for extracting a JSON representation of the declarations in a Go source file.

Installing

go get -u github.com/ramya-rao-a/go-outline

Using

> go-outline -f file.go
[{"label":"proc","type":"package",<...>}]

To parse and return only imports

> go-outline -f file.go -imports-only

To parse unsaved file contents, use the -modified flag along with the -f flag and write an archive to stdin.
File in the archive will be preferred over the one on disk.

The archive entry consists of:

• the file name, followed by a newline
• the (decimal) file size, followed by a newline
• the contents of the file
