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


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.

-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)}.


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 -S
create transducers

"cat" and "dog" and "3"
