💖 fstshortestdistance(1) 💖

okay so bestie, welcome to the manual page for fstshortestdistance — she lives in section 1, User Commands, and she's about to find shortest distances in an FST like it's her whole personality. no cap, she ate. 💅

🌸 NAME 🌸

fstshortestdistance — find shortest distances in an FST ✨

🦋 SYNOPSIS 🦋

fstshortestdistance [OPTIONS] [in.fst [distance.txt]]

💜 DESCRIPTION 💜

Finds shortest distance(s) in an FST. that's it, that's the vibe, that's the whole job. she's giving focused. she's giving main character. 🫶

🎀 OPTIONS 🎀

quick lil heads up before we get into it: Boolean options accept either true or false as a value, or the implicit value true if neither value is specified. so like, if you just say the flag with no value, it's a yes. periodt. 👑

  • --delta=VALUE — Set the comparison/quantization delta. Default: 0.000976562. 🍓
  • --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. For example, FSTs are returned with the kError property set to true, and FST weights set so that Member() returns false. Default: true. 😭 (yes bestie this one is serious, fatal means FATAL)
  • --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.
  • --nstate=NUMBER — Set the state number threshold. Default: -1.
  • --queue_type=TYPE — Set the queue type, one of auto, fifo, lifo, shortest, state, and top. Default: auto. ✨
  • --reverse[=BOOLEAN] — Perform in the reverse direction. Default: false. 🔄 (go backwards, queen)
  • --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.

like, the whole friend group. go say hi. 💕

and that's the whole page, bestie!! this was OpenFst 1.8.5, dated Mar 2026, and honestly? iconic. slay. go find your shortest distances. mwah. 💖✨🎀🦋
