OPTIONS

Boolean options accept either true or false as a value, or the implicit value true if neither value is specified.

--filename_prefix=STRING

Set the prefix to prepend to filenames. Default: no prefix.

--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.

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".

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.

--key-separator=CHARACTER

Set the character separator between groups of keys. Default: comma.

--range-delimiter=CHARACTER

Set the character separator between the start and end keys of a range. Default: hyphen.

--save_relabel_ipairs=FILENAME

Save input relabel pairs to file. Default: do not save.

--save_relabel_opairs=FILENAME
