🌸 NAME 🌸

fstconvert — convert an FST to another type 💅 bestie, that's literally the whole job.

✨ SYNOPSIS ✨

fstconvert [OPTIONS] [in.fst [out.fst]]

💖 DESCRIPTION 💖

Converts an FST to another type. That's it, that's the vibe 🦋 you hand it one flavor of FST, it hands you back another one, no cap.

🎀 OPTIONS 🎀

okay so real quick before the list: boolean options are the chill ones. You can pass either true or false as the value, OR you can just... say nothing and they'll quietly assume true. Implicit true energy ✨

  • --fst_align[=BOOLEAN] — writes FST data aligned wherever it makes sense to. Default: false.
  • --fst_compat_symbols[=BOOLEAN] — requires symbol tables to match, when appropriate. Default: true.
  • --fst_default_cache_gc[=BOOLEAN] — turns on garbage collection for the cache. Default: true.
  • --fst_default_cache_gc_limit=N — sets the cache byte size that makes garbage collection kick in. 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, five whole spaces, she's committed).
  • --fst_read_mode=STRING — sets the default file reading mode for mappable files, and your choices are "read" or "map". Default: "read".
  • --fst_type=TYPE — sets the output FST type. Default: vector.
  • --fst_verify_properties[=BOOLEAN] — verifies the fst properties queried by TestProperties. Default: false.
  • --fst_weight_parentheses=STRING — sets the characters that enclose the first weight of a printed composite weight (think pair weight, tuple weight, and derived classes) so that nested composite weights get proper I/O 🫶. It must have size 0 (meaning none) or size 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.
  • --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.
  • --tmpdir=PATHNAME — sets the temporary directory to use. Default: /tmp.
  • --v[=N] — sets the verbosity level. Default: 0.
