✨ fstdisambiguate — disambiguate an FST ✨

okay bestie, welcome to the fstdisambiguate(1) page, a User Command and honestly? lowkey iconic 💅

---

🌸 NAME 🌸

fstdisambiguate — disambiguate an FST. that's it. that's the whole vibe.

---

🦋 SYNOPSIS 🦋

fstdisambiguate [OPTIONS] [in.fst [out.fst]]

like… you give it an FST (or don't, it's chill), you get an FST back. main character energy fr fr ✨

---

🎀 DESCRIPTION 🎀

Disambiguates an FST. no cap, that is literally the entire description. it takes an FST and it makes it disambiguated. the way that it just does that 🫶

---

💖 OPTIONS 💖

quick housekeeping before we get into it, bestie: boolean options are super flexible — you can pass either true or false as a value, OR you can just say nothing at all and it'll assume the implicit value true. so --fst_align and --fst_align=true are giving the same thing 💅

• --delta=VALUE — sets the comparison/quantization delta. default: 0.000976562. tiny little number, big responsibilities 🍓
• --fst_align[=BOOLEAN] — write FST data aligned where appropriate. default: false.
• --fst_compat_symbols[=BOOLEAN] — require symbol tables to match when appropriate. default: true. it WILL check, don't try it 🙈
• --fst_default_cache_gc[=BOOLEAN] — enable garbage collection of cache. default: true. the cache cleans up after itself, so organized ✨
• --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 the returned objects get flagged as bad instead. like, for example: FSTs come back with the kError property set to true, and FST weights get set so that Member() returns false. default: true. so by default? it's giving fatal 💀
• --fst_field_separator=STRING — set the characters used as a separator between printed fields. default: " " (yes, that's spaces, not empty quotes, read it carefully bestie 👀).
• --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 (think pair weight, tuple weight, and derived classes) so nested composite weights do proper I/O. 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. your bestie when you're lost 🫶
• --helpshort[=BOOLEAN] — show brief usage information. default: false. the tl;dr version.
• --nstate=NUMBER — set the state number threshold. default: -1.
• --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.
• --subsequential_label=LABEL — set the input label of the arc corresponding to residual final output when producing a subsequential transducer. default: 0.
• --tmpdir=PATHNAME — set the temporary directory to use. default: /tmp.
• --v[=N] — set the verbosity level. default: 0. turn it up for ✨lore✨, turn it down for peace.
• --weight=THRESHOLD — set the weight threshold. default: "".
