    Gron! It transforms JSON into greppable lines like path.to.items[3] = value, and if you like you can edit the result and use gron to transform the edited stuff back to JSON. This brings JSON structures into the line-oriented sed/grep/awk universe – I’m looking at you, Jupyter notebooks. I’ve only had gron for a few months, and it’s already my 13th-most-used command.

    Example output (gron can read from stdin, files, and even URLs):

    ▶ gron testdata/two.json 
json = {};
json.contact = {};
json.contact.email = "mail@tomnomnom.com";
json.contact.twitter = "@TomNomNom";
json.github = "https://github.com/tomnomnom/";
json.likes = [];
json.likes[0] = "code";
json.likes[1] = "cheese";
json.likes[2] = "meat";
json.name = "Tom";```

      Thanks for mentioning this! I had no idea this existed, but is definitely in line with how my brain works vs jq. Even though I use jq almost daily, I can never remember some of the syntax.

        I created an alias for jq, called jqpath, that leverages fzf to give searchable output similar to gron, but that emits it in jq’s expected format: https://twitter.com/tednaleid/status/1302477635914739713

          Oh wow, I just noticed @mrcruz’s recommendation of xml2, elsewhere on this page, which does something similar for HTML and XML. Although for HTML I had hoped it would include element classes and IDs in the path — .../div/div/... is not useless, but .../div.comment#c_tez5vc/div.details/... would have provided more orientation points. Still, this is going in my toolbox; and I thought you might like it, too.

        tednaleid avatar tednaleid 2 years ago | link | on: What debugging technique did it take you entirely too long to learn?

        in bash scripts, using set -x to emit all of the commands that are being executed (and turning it off with set +x). Lets you quickly figure out what is wrong with the script.

          tednaleid avatar tednaleid 4 years ago | link | on: tj - stdin line timestamps

          Neat! I love single purpose shell utilities composes with other commands (“do one thing well”). I like that this also plays nicely with jq, which is one of my favorite tools.

          For me, small, standalone binaries like this are where golang shines brightest. I created a cmdline tool called ganda (https://github.com/tednaleid/ganda) that can take thousands of piped urls and it’ll download them all in parallel and pipe the results on stdout to something like jq (or save to a file). I think the json output of tj might fit well with this, I’ll give it a shot.
