NAME

       hfst-lookup - =perform transducer lookup (apply)

SYNOPSIS

       hfst-lookup [OPTIONS...] [INFILE]

DESCRIPTION

       perform transducer lookup (apply)

   Common options:
       -h, --help
              Print help message

       -V, --version
              Print version info

       -v, --verbose
              Print verbosely while processing

       -q, --quiet
              Only print fatal erros and requested output

       -s, --silent
              Alias of --quiet

   Input/Output options:
       -i, --input=INFILE
              Read input transducer from INFILE

       -o, --output=OUTFILE
              Write output to OUTFILE

       -p, --pipe-mode[=STREAM] Control input and output streams

   Lookup options:
       -I, --input-strings=SFILE
              Read lookup strings from SFILE

       -O, --output-format=OFORMAT
              Use OFORMAT printing results sets

       -e, --epsilon-format=EPS
              Print epsilon as EPS

       -F, --input-format=IFORMAT
              Use IFORMAT parsing input

       -x, --statistics
              Print statistics

       -X, --xfst=VARIABLE
              Toggle xfst VARIABLE

       -c, --cycles=INT
              How many times to follow input epsilon cycles

       -b, --beam=B
              Output only analyses whose weight is within B from the best analysis

       -t, --time-cutoff=S
              Limit search after having used S seconds per input (currently only works in optimized-lookup mode

       -P, --progress
              Show neat progress bar if possible

       If  OUTFILE or INFILE is missing or -, standard streams will be used.  Format of result depends on format
       of  INFILE  OFORMAT  is  one  of  {xerox,cg,apertium},  xerox   being   default   IFORMAT   is   one   of
       {text,spaced,apertium},  default  being text, unless OFORMAT is apertium VARIABLEs relevant to lookup are
       {print-pairs,print-space, quote-special,show-flags,obey-flags}  Input  epsilon  cycles  are  followed  by
       default  INT=5 times.  Epsilon is printed by default as an empty string.  B must be a non-negative float.
       S must be a non-negative float. The default, 0.0, indicates no cutoff.  If  the  input  contains  several
       transducers, a set containing results from all transducers is printed for each input string.

       STREAM  can be { input, output, both }. If not given, defaults to {both}.  If input file is not specified
       with -I, input is read interactively line by line from the user. If you redirect input from a  file,  use
       --pipe-mode=input.  --pipe-mode=output is ignored on non-windows platforms.

   Todo:
              For  optimized  lookup  format,  only strings that pass flag diacritic checks are printed and flag
              diacritic symbols are not printed.  Support VARIABLE 'print-space' for optimized lookup format

   Known bugs:
              'quote-special' quotes spaces that come from 'print-space'
