GENNORM2(8)

okay so bestie, we're looking at gennorm2 from the ICU 77.1 Manual, section 8 — the system-administration girlies' section 💅 she builds binary data files full of Unicode normalization data and honestly? iconic.

🎀 NAME 🎀

gennorm2 — builds binary data file with Unicode normalization data. no cap, that's the whole job description 🫶

---

✨ SYNOPSIS ✨

gennorm2 [ -h, -?, --help ] [ -V, --version ] [ -c, --copyright ] [ -v,
--verbose ] [ -u, --unicode unicode-version-number ] [ -s, --sourcedir
source-directory ] [ -o, --output output-filename ] --fast

---

🌸 DESCRIPTION 🌸

so here's the vibe: gennorm2 reads text files that define Unicode normalization, them, and builds a binary data file. (yes bestie, the page literally says "them" right there and I am not the one who's gonna touch it 😭 the facts stay exactly as they are, periodt.)

---

💖 OPTIONS 💖

• -h, -?, --help — print help about usage and exit. your "what do I even do here" button 🧚
• -V, --version — print the version of gennorm2 and exit. who am I? what am I? answered ✨
• -c, --copyright — include a copyright notice. legal girlie behaviour 💜
• -v, --verbose — display extra informative messages during execution. she's telling you everything and honestly we love that 🙈
• -u, --unicode — specify Unicode version number, such as 5.2.0. pick your era, bestie 🦋
• -s, --sourcedir source-directory — specify the input directory. where the files live 🍓
• -s, --sourcedir source-directory — set the name of the output file. (and yes, this is listed exactly like this, twice, with the same flag spelling — I'm not rewriting it, I'm just reporting it, the manpage said what it said 💀)
• --fast — optimize the .nrm file for fast normalization, which might increase its size. (writes fully decomposed regular mappings instead of delta mappings. you should measure the runtime speed to make sure that this is a good trade-off.) so like… faster lookups, bigger file, and you have to do the benchmarking to see if it's worth it. do not skip the measuring step, that's the whole caveat ⭐

heads up: --fast is not a free glow-up. it might increase the size of your .nrm file, and the page is very clear that measuring the runtime speed is on you to confirm the trade-off is worth it 🔥
