fstsynchronize(1)

💫 fstsynchronize — the manual page, but make it cute 💫

okay bestie, so this is fstsynchronize(1), a User Command from the OpenFst fam. Let's get into it. ✨

---

🌸 NAME 🌸

fstsynchronize — synchronize an FST 💅

---

🎀 SYNOPSIS 🎀

fstsynchronize [OPTIONS] [in.fst [out.fst]]

---

🦋 DESCRIPTION 🦋

Synchronizes an FST. that's it, that's the whole vibe. she syncs, she slays, she returns. 🫶

---

✨ OPTIONS ✨

okay so this is the part where we go through literally every single flag, no skipping, no cap. 📋

🗒️ heads up: boolean options accept either true or false as a value, or the implicit value true if you don't specify either one. so like, --fst_align and --fst_align=true are the same energy. periodt.

• --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.
• --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.
