💖 fsttopsort — the manual page, but make it cute 💖

okay so bestie, welcome to fsttopsort(1) 🦋 — that's a User Commands situation, section 1, the big leagues. sit down, grab a strawberry, we're gonna topologically sort an FST and it's gonna be adorable.

✨ NAME ✨

fsttopsort — topologically sort an FST. that's it. that's the whole job. she's an icon, she's a legend, and she is exactly what she says on the tin 👑

---

🌸 SYNOPSIS 🌸

fsttopsort [OPTIONS] [in.fst [out.fst]]

---

🎀 DESCRIPTION 🎀

Topologically sorts an FST. periodt. 💅

---

💜 OPTIONS 💜

okay so first, the rules of the game: Boolean options accept either true or false as a value — or you can just say nothing and they implicitly take true. no value, no problem, bestie 🫶

• --fst_align[=BOOLEAN] — write FST data aligned where appropriate. Default: false.
• --fst_compat_symbols[=BOOLEAN] — require symbol tables to match when appropriate. Default: true.
• --fst_default_cache_gc[=BOOLEAN] — enable garbage collection of cache. Default: true.
• --fst_default_cache_gc_limit=N — set the cache byte size that triggers garbage collection. Default: 1048576.
• --fst_error_fatal[=BOOLEAN] — if true, FST errors are fatal. otherwise, returned objects are flagged as bad. like, for example: FSTs get returned with the kError property set to true, and FST weights get set so that Member() returns false. Default: true.
• --fst_field_separator=STRING — set the characters used as a separator between printed fields. Default: " ".
• --fst_read_mode=STRING — set the default file reading mode for mappable files, either "read" or "map". Default: "read".
• --fst_verify_properties[=BOOLEAN] — verify fst properties queried by TestProperties. Default: false.
• --fst_weight_parentheses=STRING — set the characters enclosing the first weight of a printed composite weight (e.g., pair weight, tuple weight, and derived classes) to ensure proper I/O of nested composite weights. must have size 0 (none) or 2 (open and close parenthesis). Default: no parentheses.
• --fst_weight_separator=CHARACTER — set the character separator between printed composite weights. Default: comma.
• --help[=BOOLEAN] — show usage information. Default: false.
• --helpshort[=BOOLEAN] — show brief usage information. Default: false.
• --save_relabel_ipairs=FILENAME — save input relabel pairs to file. Default: do not save.
• --save_relabel_opairs=FILENAME — save output relabel pairs to file. Default: do not save.
• --tmpdir=PATHNAME — set the temporary directory to use. Default: /tmp.
• --v[=N] — set the verbosity level. Default: 0.

💀 heads up bestie: --fst_weight_parentheses is not freestyle. it must have size 0 (none) or 2 (open and close parenthesis). no in-between. the vibes will not save you here 🙈
