JSON Lines is such a delight to use. It's particular nice as a CLI interop format.
You can use dumb, fast tools (e.g. grep to quickly filter large outputs) as well as structured tools (e.g. jq).

I periodically see "diffstatic" as a typo of difftastic. I quite like it: makes me think of 'ecstatic' rather than 'fantastic'.
I've eventually configured typos CLI to prevent this spelling on the difftastic repo, but it makes me smile every time.
It's confusing how 'REPL' refers to two different UIs:
A CLI like IPython or Julia, where things like multiline editing and syntax highlighting need careful implementation.
An editor protocol like SLIME or CIDER where multiline editing is a total non-issue.
AI agents (OpenClaw, Hermes Agent etc) seem to be increasingly standardising their design.
You have a UI for the markdown files writable by the agent (sometimes just Obsidian) plus a set of CLI tools for performing actions.
I've seen so many new CLIs recently too.
