fstmap(1)

NAME
fstmap - map an operation over an FST

SYNOPSIS
fstmap [OPTIONS] [in.fst [out.fst]]

DESCRIPTION

Applies an operation to each arc of an FST.

OPTIONS

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

--delta=VALUE
    Set the comparison/quantization delta for a quantize operation. 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.

--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.

--map_type=TYPE
    Set the map operation, one of arc_sum, identity, input_epsilon, invert, output_epsilon, plus (--weight), quantize (--delta), rmweight, superfinal, times (--weight), to_log, and to_log64. Default: identity.

--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.

--weight=VALUE
    Set the weight for a plus or times operation. Default: "".
