hfst-strings2fst [OPTIONS...] [INFILE]


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
Divide each weight by sum of all weights (with option -j)
Take negative natural logarithm of each weight
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.


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
