NAME

       fstcompress - compress and decompress FSTs

SYNOPSIS

       fstcompress   [OPTIONS]   [in.fst  [out.fstz]]  fstcompress  [OPTIONS]  --decode  [in.fstz
       [out.fst]]

DESCRIPTION

       Compresses and decompresses FSTs.

OPTIONS

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

       --arc_type=TYPE
              Set the output arc type.  Default: standard.

       --decode[=BOOLEAN]
              Decompress.  Default: false (compress).

       --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.

       --gzip[=BOOLEAN]
              Apply  gzip  compression  after  LZA  compression, or gzip decompression before LZA
              decompression (recommended).  Default: false.

       --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.
