okay bestie, welcome to the farisomorhic(1)</p> page, aka the vibe check for your finite-state archives ✨

🌸 NAME 🌸

farisomorphic — test if the FSTs in two finite-state archives are isomorphic 🦋

✨ SYNOPSIS ✨

farisomorphic [OPTIONS] in1.far in2.far

💅 DESCRIPTION 💅

So like, it tests if two finite-state archives contain isomorphic (key,fst) pairs. That's it. That's the whole thing. Two archives walk in, and this lil guy goes "are you the same bestie in different fonts?" 👑

🎀 OPTIONS 🎀

Lowkey important housekeeping first: boolean options accept either true or false as a value, or the implicit value true if neither value is specified. no cap. 🙈

• --begin_key=STRING — First key to extract. Default: first key in the archive.
• --delta=VALUE — Set the comparison/quantization delta. Default: 0.000976562.
• --end_key=STRING — Last key to extract. Default: last key in the archive.
• --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.

🫶 just a heads up bestie, a bunch of these default values and accepted values are doing a LOT of quiet work in the background — read them before you go changing stuff, fr fr.
