fstreplace(1) replace FST arcs with other FSTs

SYNOPSIS

fstreplace [OPTIONS] root.fst rootlabel [rule.fst label...] [out.fst]]

DESCRIPTION

Performs dynamic replacement of arcs in one FST with another FST, allowing for the definition of FSTs analogous to RTNs.

OPTIONS

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

--call_arc_labeling=STRING
Which labels to make non-epsilon on the call arc, one of "input", "output", "both", and "neither". Default: "input".
--epsilon_on_replace[=BOOLEAN]
For backwards compatibility: call/return arcs are epsilon arcs. Default: false.
--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.
--return_arc_labeling=STRING
Which labels to make non-epsilon on the return arc, one of "input", "output", "both", and "neither". Default: "neither".
--return_label=INTEGER
Label to put on return arc. Default: 0.
--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.
