This is an informal request for comments to the world for a new file format called Nest, a simple, line-oriented data serialisation format.

It’s reminiscent of YAML, but stubbornly simple like Gemini. It’s designed to be dead easy to implement and handle in terms of the Unix Philosophy.
It only stores strings within maps and sequences. There’s no “null”. Strings can be inline or multiline. As of the current revision of Nest, certain strings are invalid, namely when a multiline string doesn’t have a trailing newline character. This is something I’d like to reconcile.
I have had various spurs of thought for revisions or new syntaxes. You can see a few on the Fediverse.
This file format was primarily inspired by the NestedText project. I had made my own implementation of NestedText in Go, but a new version of the spec was release, which in my opinion deviated too greatly into needless complexity.
Please send in your thoughts and contributions in the comments.
