In 2011, a bug in how HFST handles words containing spaces was documented and resolved (apparently in r1518?), but it introduced a new bug. This page documents the new behaviour.

text.lexc

Make sure to include the space in '% ' under Multichar_Symbols.

Multichar_Symbols

% 

LEXICON Root

erke:erke # ;
erke% me:erke% me # ;
medvedev:medvedev # ;

Compiling

  1. $ hfst-lexc test.lexc -o test.hfst
  2. $ hfst-invert test.hfst | hfst-fst2fst -w -o test.hfst.ol

Testing

Some correctly analysed forms

  • $ echo "erke" | hfst-proc test.hfst.ol
^erke/erke$
  • $ echo "erke me" | hfst-proc test.hfst.ol
^erke me/erke me$
  • $ echo "medvedev" | hfst-proc test.hfst.ol
^medvedev/medvedev$

The incorrectly analysed form

  • $ echo "erke medvedev" | hfst-proc test.hfst.ol
^erke medvedev/*erke medvedev$

Expected output

This form is analysed correctly by a transducer identical to the one above except with the "erke me" form removed:

  • $ echo "erke medvedev" | hfst-proc test2.hfst.ol
^erke/erke$ ^medvedev/medvedev$
