👑 fstdeterminize 👑

okay so bestie, welcome to fstdeterminize(1) — she's a User Commands baddie and honestly? iconic. the way this girl takes an FST and makes it deterministic? obsessed. 💖

✨ NAME ✨

fstdeterminize — determinize an FST 🦋

🌸 SYNOPSIS 🌸

fstdeterminize [OPTIONS] [in.fst [out.fst]]

💅 DESCRIPTION 💅

So basically, she determinizes an FST. that's the whole vibe, that's the main character energy. 💫

ngl if the input FST is already deterministic? she literally leaves it alone, untouched, no notes. but if it's nondeterministic?? she serves you an equivalent deterministic FST instead. slay.

🎀 OPTIONS 🎀

fr fr, boolean options are flexible like that: they accept either true or false as a value, or — if you don't give them a value at all — they just implicitly mean true. she's not needy. 💖

• --delta=VALUE — sets the comparison/quantization delta. default: 0.000976562. tiny number, big job. ✨
• --det-type=TYPE — the type of determinization, and it has to be one of functional, nonfunctional, or disambiguate. default: functional.
• --fst_align[=BOOLEAN] — writes FST data aligned where appropriate. default: false.
• --fst_compat_symbols[=BOOLEAN] — requires symbol tables to match when appropriate. default: true.
• --fst_default_cache_gc[=BOOLEAN] — enables garbage collection of the cache. default: true.
• --fst_default_cache_gc_limit=N — sets 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, FSTs come back with the kError property set to true, and FST weights get set so that Member() returns false. default: true.
• --fst_field_separator=STRING — sets the characters used as a separator between printed fields. default: " " (yes that's the actual string, bestie, don't come for her).
• --fst_read_mode=STRING — sets the default file reading mode for mappable files, either "read" or "map". default: "read".
• --fst_verify_properties[=BOOLEAN] — verifies fst properties queried by TestProperties. default: false.
• --fst_weight_parentheses=STRING — sets the characters enclosing the first weight of a printed composite weight (think pair weight, tuple weight, derived classes) so that 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 — sets the character separator between printed composite weights. default: comma.
• --help[=BOOLEAN] — shows usage information. default: false.
• --helpshort[=BOOLEAN] — shows brief usage information. default: false.
• --increment-subsequential-label[=BOOLEAN] — increments subsequential_label to obtain distinct labels for subsequential arcs at a given state. default: false.
• --nstate=NUMBER — sets the state number threshold. default: -1.
• --save_relabel_ipairs=FILENAME — saves input relabel pairs to a file. default: do not save.
• --save_relabel_opairs=FILENAME — saves output relabel pairs to a file. default: do not save.
• --subsequential_label=LABEL — sets the input label of the arc corresponding to the residual final output when producing a subsequential transducer. default: 0.
• --tmpdir=PATHNAME — sets the temporary directory to use. default: /tmp.
• --v[=N] — sets the verbosity level. default: 0.
• --weight=THRESHOLD — sets the weight threshold. default: "".

okay that's the whole page, bestie!! 🫶 this one comes from OpenFst 1.8.5, dated Mar 2026, and yeah — she's giving <rainbow>fstdeterminize(1)</rainbow> energy, periodt. go determinize something gorgeous. 💜✨🎀
