I want to extract and process the metadata from PNG images and the first line of .safetensors files for LLM’s and LoRA’s. I could spend ages farting around with sed or awk but formats of files are constantly changing. I’d like a faster way to see a summary of training and a few other details when they are available.

      I have a very handy command in my .vimrc for this -

      command! JSON setlocal filetype=json | %!jq .

      Anytime I’m in a json file that isn’t formatted it’s as simple as typing :JSON to have it all sorted.

      Yeah, I’ve been learning some nushell. If you’re dealing with data, it’s just a great tool. So many sharp edges in the POSIX shell come from it being stringly typed, so having a strongly typed shell is extremely helpful.

    A week ago I would have said jq, but just the other day I discovered nushell and have been loving it, if you deal with structured data often it’s way easier, just bear in mind it’s not POSIX compatible

    What are some goos resources for learning jq? I really struggle when it comes to nested keys/values which obviously limits my ability to use it.

        I have perused it, but its both so dense and so broad that its not that helpful unless i know exactly what I’m looking for. I have also tried info and tldr. I actually like tldr the most,. although the exhaustiveness of the man pages must be admired. I dont find it to be the best teacher.

    Python is very good for working with JSON. Definitely will get you there faster than awk for anything not completely trivial.

      I found a Python project that does enough for my needs. Jq looks super powerful though. Thanks. I managed to get yq working for PNG’s, but I had trouble with both jq and yq with safetensor files. I couldn’t figure out how to parse a string embedded in an inconsistent starting binary, and with massive files. I could get in and grab the first line with head. I tried some stuff with expansions, but that didn’t work and sent me looking for others that have solved the issue better than myself.

    Probably not popular opinion, but pwsh (powershell). It’s got a lot of tooling built in and means I don’t have to learn a different tool just because I’m in a different system.
