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"
