hfst-regexp2fst(1)

Usage

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

Overview

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"
