I’m building a Unicode reference where each symbol has its own dev-friendly page with all relevant encodings. Example: [https://fontgenerator.design/symbol/almost-equal-to](https://fontgenerator.design/symbol/almost-equal-to) Includes Unicode, HTML, CSS, JS, UTF-8/16 bytes, URL encoding, and usage examples. The same structure is used across thousands of symbols (math, arrows, currency, tech/UI, punctuation). Built because existing references are fragmented. Feedback welcome.

Hey HN, I find myself reaching for tools like it-tools.tech or other random sites every now and then during development or debugging. So, I built a toolkit with a sane and simple CLI interface for most of those tools. For the curious and lazy, at the moment, ut has tools for, - Encoding: base64 (encode, decode), url (encode, decode) - Hashing: md5, sha1, sha224, sha256, sha384, sha512 - Data Generation: uuid (v1, v3, v4, v5), token, lorem, random - Text Processing: case (lower, upper, camel, title, constant, header, sentence, snake), pretty-print, diff - Development Tools: calc, json…

Hey folks! I know CSV parsers (especially in JS) aren't terribly exciting and someone writes a "better" one every week. I'm in the middle of my parental leave, and this was a project that came out of me looking for the fastest/smallest CSV parser. It all started so innocently, and then turned into a benchmark-validation-athon; the library itself took ~2 weeks to write, but the performance comparisons took another ~4 weeks (on and off). The benchmarks were a huge effort, but I think they are the most thorough to date, both in breadth and in depth, so hopefully you find them useful:…

Took a stab at building my own string diffing JS package. I built an interactive demo for TypeIt’s website (https://typeitjs.com/build-your-own) a while back. The approach I took to handle user input necessitated a way to calculate the difference between the versions of a user’s text input. I searched around for a package to help me out and found a couple of good ones (like fast-diff), but I either didn’t really like their API or didn’t want to take on a huge new dependency. Instead, I thought I’d give it a shot myself (famous last words). I dove into it having no real formal…

* https://sparser.io * https://github.com/Unibeautify/sparser This is my attempt at creating a universal language parser. It attempts to solve a couple of problems: * Support multiple languages * Recursively extend support to languages embedded within other languages * Output a uniform format for all supported languages This is a personal project so any feedback would be helpful. Something interesting I found after I built it is that this parser is not as fast to write output as many other JavaScript parsers, but its output is much faster to read from due to the…

Wrote this to learn more about the `chumsky` parser combinator library, rustyline, and the `ariadne` error reporting crate. Such a nice DX combo for writing new languages. Still a work in progress, but I thought I'd share :)

Hi HN! I've spent the last few weeks optimizing the string operations in StringZilla. You'd be surprised how much performance GLibc and the Standard Templates Library of C++ are leaving on the table, especially on Arm and, likely, on RISC-V. I've significantly increased the number of implemented algorithms for different workloads. Searching across English texts on Arm, for example: - is 4.4x faster than STL, - and 16.8x faster in reverse order. The new version of the library now includes a C++ binding largely compatible with the C++ Standard, featuring all 17 overloads of the `replace`…
