txtpbfmt parses, edits and formats text proto files in a way that preserves comments.

This saves development (read/edit/review) time and enables automated edits.

Install:

$ go install github.com/protocolbuffers/txtpbfmt/cmd/txtpbfmt@latest

Format files in-place:

$ ${GOPATH}/bin/txtpbfmt [FILES]

Write formatted input to stdout:

$ ${GOPATH}/bin/txtpbfmt < [FILE]

Main features:

Yes, see ast.go.

You can disable formatting for a whole file by adding a comment with "# txtpbfmt: disable" to the top of the file (before the first non-empty non-comment line), eg:

# File overview ...

# txtpbfmt: disable

content: { ... }

The .textproto extension is the most used extension inside Google (the second most popular choice is .textpb).

Currently there is no open source integration with any editor.
