Ask HN: What is your “I don't care if this succeeds” project?
Last February there was, in my opinion, a really uplifting thread with the same title¹. I'd like to see all the cool new things going on, and I'll steal the intro text from as89 to explain:<p><i>One where you don't care if it makes money or gets a lot of attention, but you are working on it regardless. I don't think I mean private hobbies, exactly, but projects that could or will be shared with others - you just don't care about the outcome.</i><p>¹ <a href="https://news.ycombinator.com/item?id=25992782" rel="nofollow">https://news.ycombinator.com/item?id=25992782</a>

Show HN: Jless, a command-line JSON viewer
Hey, Hacker News! Today I'm proud to release jless, a command-line JSON viewer.<p>jless provides a JSON viewing experience similar to what you see in a browser's network tab in the developer console, but from the comfort of your terminal, with a whole suite of vim-inspired key bindings to easily manipulate your view of the data and full-text regex search. I'm sure many of you have some piped together some combination of cat, jq and less before; hopefully jless can replace that usage (hence the name). It supports newline delimited JSON too, so it can handle any output from jq.<p>I built jless to solve a problem I kept facing while building plaintextsports.com [1][2]. For the live data I use a lot of public, but undocumented APIs, and I was constantly digging through giant JSON files to understand how the data was structured. I tried installing multiple Chrome extensions, but was dissatisfied with all of them. I piped files through jq into less a lot, and that was ok, but not great. The Preview pane in the Network tab of Chrome's dev tools was pretty useful, and I modeled a lot of jless's behavior and appearance off of that, but it didn't fit well into my tmux + vim dev environment, and I couldn't easily use it to inspect files on disk. I wanted that experience, but in my terminal (and with search support).<p>Once I had built a rudimentary version of jless a few months ago, I immediately started using it whenever I was debugging something, and my usage has only grown as I've added more basic functionality. I've finally added all the features I feel like it needs to be functional, useful, and reliable.<p>There's definitely more features I want to add: Windows support, some way to filter data with jq filters (a la fx [3]), yanking objects to the clipboard, being able to hide keys entirely, streaming data in, so you can peek at the start of gigantic file, maybe a way to extract a schema from a file (like [4]), plenty of low-hanging fruit for performance. Support for different hierarchical data formats (YAML, TOML, XML) could be cool someday. I'm sure many people will ask for editing support, but sadly that is not something I plan on adding anytime soon.<p>I also used this project as a chance to learn Rust (code style and design comments appreciated!), which I had only dabbled with before. For a command-line utility, this felt like an obvious choice: small binaries (~3mb), instant startup, and great performance without any effort (try searching for comma in a big file!).<p>I hope you find it useful!<p>[1]: <a href="https://plaintextsports.com" rel="nofollow">https://plaintextsports.com</a>, live sports scores in plain text, no ads, no tracking, no loading<p>[2]: <a href="https://news.ycombinator.com/item?id=26310314" rel="nofollow">https://news.ycombinator.com/item?id=26310314</a><p>[3]: <a href="https://news.ycombinator.com/item?id=29861043" rel="nofollow">https://news.ycombinator.com/item?id=29861043</a><p>[4]: <a href="https://quicktype.io/typescript" rel="nofollow">https://quicktype.io/typescript</a>
