SYNOPSIS

9       fstdifference [OPTIONS] in1.fst in2.fst [out.fst]
10

DESCRIPTION

12       Subtracts an unweighted DFA from an FSA.
13

OPTIONS

15       Boolean options accept either true or false as a value, or the implicit
16       value true if neither value is specified.
17
18       --connect[=BOOLEAN]
19              Trim output.  Default: true.
20
21       --fst_compat_symbols[=BOOLEAN]
22              Require symbol tables to match when appropriate.  Default: true.
23
24       --fst_default_cache_gc[=BOOLEAN]
25              Enable garbage collection of cache.  Default: true.
26
27       --fst_verify_properties[=BOOLEAN]
28              Verify  fst  properties  queried  by  TestProperties.   Default:
29              false.
30
31       --help Show usage information.
32
33       --compose_filter[=TYPE]
34              Set  the  composition  filter, one of alt_sequence, auto, match,
35              and sequence.  Default: auto.
36
37       --fst_field_separator=STRING
38              Set the characters used as a separator between  printed  fields.
39              Default: "     ".
40
41       --fst_weight_parentheses=STRING
42              Set  the characters enclosing the first weight of a printed com‐
43              posite weight (e.g., pair  weight,  tuple  weight,  and  derived
44              classes) to ensure proper I/O of nested composite weights.  Must
45              have size 0 (none) or 2 (open and close parenthesis).   Default:
46              no parentheses.
47
48       --fst_weight_separator=CHARACTER
49              Set  the  character separator between printed composite weights.
50              Default: comma.
51
52       --save_relabel_ipairs=FILENAME
53              Save input relabel pairs to file.  Default: do not save.
54
55       --save_relabel_opairs=FILENAME
56              Save output relabel pairs to file.  Default: do not save.
57
58       --tmpdir=PATHNAME
59              Set the temporary directory to use.  Default: /tmp.
60
61       --v[=N]
62              Set the verbosity level.  Default: 0.
63
64       --fst_default_cache_gc_limit=N
65              Set the  cache  byte  size  that  triggers  garbage  collection.
66              Default: 1048576.
