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 and optimization options:
- -H, --do-not-harmonize
-
Do not expand '?' symbols.
- -F, --harmonize-flags
-
Harmonize flag diacritics.
- -E, --encode-weights
-
Encode weights when minimizing (default is false).
- -M, --do-not-minimize
-
Determinize result instead of minimizing it.
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 -S
-
create transducers
-
"cat" and "dog" and "3"
