SYNOPSIS
hfst-strings2fst [OPTIONS...] [INFILE]DESCRIPTION
Compile string pairs and pair-strings 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 strings from INFILE
- -o, --output=OUTFILE
- Write output transducer to OUTFILE
String and format options:
- -f, --format=FMT
- Write result in FMT format
- -j, --disjunct-strings
- Disjunct all strings instead of transforming each string into a separate transducer
- --norm
- Divide each weight by sum of all weights (with option -j)
- --log
- Take negative natural logarithm of each weight
- --log10
- Take negative 10-based logarithm of each weight
- -p, --pairstrings
- Input is in pairstring format
- -S, --has-spaces
- Input has spaces between symbols/symbol pairs
- -e, --epsilon=EPS
- Interpret string EPS as epsilon.
- -m, --multichar-symbols=FILE
- Strings that must be tokenized as one symbol.
If OUTFILE or INFILE is missing or -, standard streams will be used. FMT can be { foma, openfst-tropical, openfst-log, sfst, optimized-lookup-weighted, optimized-lookup-unweighted }. If EPS is not defined, the default representation of @0@ is used. Option --norm precedes option --log. The FILE of option -m lists all multichar-symbols, each symbol on its own line. Backslash '\' may be used to escape ':', tab and itself. For any other symbol x '\x' means x literally, i.e. is the same as 'x'. The weight of a string can be given after the string separated by a tabulator. The weight cannot be zero.
EXAMPLES
- echo "cat:dog" | hfst-strings2fst
- create cat:dog fst
- echo "c:da:ot:g" | hfst-strings2fst -p
- same as pairstring
- echo "c:d a:o t:g" | hfst-strings2fst -p -S
- same as pairstring with spaces
- echo "c a t:d o g" | hfst-strings2fst -S
- same with spaces
