NAME
       hfst-regexp2fst - =Compile (weighted) regular expressions into
       transducer(s)

SYNOPSIS
       hfst-regexp2fst [OPTIONS...] [INFILE]

DESCRIPTION
       Compile (weighted) regular expressions 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 transducer from INFILE

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

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

       -j, --disjunct
              Disjunct all regexps instead of transforming each regexp into a
              separate transducer

       -l, --line
              Input is line separated (default)

       -S, --semicolon
              Input is semicolon separated

       -e, --epsilon=EPS
              Map EPS as zero, i.e. epsilon.

       -x, --xerox-composition=VALUE Whether flag diacritics are treated as
       ordinary
              symbols in composition (default is false).

       -X, --xfst=VARIABLE
              Toggle xfst compatibility option VARIABLE.

   Harmonization:
       -H, --do-not-harmonize
              Do not expand '?' symbols.

       -F, --harmonize-flags
              Harmonize flag diacritics.

       -E, --encode-weights
              Encode weights when minimizing (default is false).

       If OUTFILE or INFILE is missing or -, standard streams will be used.
       FMT must be one of the following: {foma, sfst, openfst-tropical,
       openfst-log}.  If EPS is not defined, the default representation of 0
       is used VALUEs recognized are {true,ON,yes} and {false,OFF,no}.  Xfst
       variables are {flag-is-epsilon (default OFF)}.

EXAMPLES
       echo " {cat}:{dog} " | hfst-regexp2fst
              create transducer {cat}:{dog}

       echo " {cat}:{dog}::3 " | hfst-regexp2fst
              same but with weight 3

       echo " c:d a:o::3 t:g " | hfst-regexp2fst
              same but with weight 3 in the middle

       echo " {cat}:{dog} ; 3 " | hfst-regexp2fst
              legacy way of defining weights

       echo " cat ; dog ; 3 " | hfst-regexp2fst -S
              create transducers "cat" and "dog" and "3"
