-
twol.fs.compose(f, g)[source]
Return the composition of two FSTs
-
twol.fs.concat(f, g)[source]
Return the concatenation of two FSTs
-
twol.fs.crossprod(f, g)[source]
Return the cross-product of two FSAs
-
twol.fs.expr(e)[source]
Return an FST corresponding to a XFST regular expression
-
twol.fs.intersect(f, g)[source]
Return the intersection of two FSTs
Both arguments are assumed to be length preserving mappings.
-
twol.fs.lower(f)[source]
Return the output projection of an FST
-
twol.fs.plus(f)[source]
Return the Kleene plus iteration of an FST
-
twol.fs.star(f)[source]
Return the Kleene star iteration of an FST
-
twol.fs.string_to_fsa(grapheme_string)[source]
Return a FSA which accepts the sequence of graphemes in the string
-
twol.fs.symbol_pair_to_fst(insym, outsym)[source]
“Return a FST which accepts one the pair string ‘insym:outsym’
-
twol.fs.symbol_to_fsa(sym)[source]
Return a FSA which accepts the one letter string ‘sym’
The symbol ‘sym’ may be e.g. a composed Unicode grapheme, i.e. a
string of two or more Unicode characters.
-
twol.fs.union(f, g)[source]
Return the union of two FSTs
-
twol.fs.upper(f)[source]
Return the input projection of an FST
