NAME
       hfst-strings2fst - =Compile string pairs and pair-strings into
       transducer(s)

SYNOPSIS
       hfst-strings2fst [OPTIONS...] [INFILE]

DESCRIPTION
       Compile string pairs and pair-strings into transducer(s)

   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 strings from INFILE

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

   String and format options:
       -f, --format=FMT
              Write result in FMT format

       -j, --disjunct-strings
              Disjunct all strings instead of transforming each string into a
              separate transducer

       --norm Divide each weight by sum of all weights (with option -j)

       --log  Take negative natural logarithm of each weight

       --log10
              Take negative 10-based logarithm of each weight

       -p, --pairstrings
              Input is in pairstring format

       -S, --has-spaces
              Input has spaces between symbols/symbol pairs

       -e, --epsilon=EPS
              Interpret string EPS as epsilon.

       -m, --multichar-symbols=FILE
              Strings that must be tokenized as one symbol.

       If OUTFILE or INFILE is missing or -, standard streams will be used.
       FMT can be { foma, openfst-tropical, openfst-log, sfst,
       optimized-lookup-weighted, optimized-lookup-unweighted }.  If EPS is
       not defined, the default representation of @0@ is used.  Option --norm
       precedes option --log.  The FILE of option -m lists all
       multichar-symbols, each symbol on its own line.  Backslash '\' may be
       used to escape ':', tab and itself. For any other symbol x '\x' means x
       literally, i.e. is the same as 'x'.  The weight of a string can be
       given after the string separated by a tabulator. The weight cannot be
       zero.

EXAMPLES
       echo "cat:dog" | hfst-strings2fst
              create cat:dog fst

       echo "c:da:ot:g" | hfst-strings2fst -p
              same as pairstring

       echo "c:d a:o t:g" | hfst-strings2fst -p -S
              same as pairstring with spaces

       echo "c a t:d o g" | hfst-strings2fst -S
              same with spaces
