4.3 broke synonym parsing on dictunformat -> ifo conversion

[doozan]

This may have actually been a bug, but it was a useful bug: prior to 4.3.0 a | separated list of words in a dictunformat would be split into synonyms when converting to .ifo. Is there a supported method of listing synonyms in dictunformat?

I started writing this issue as a feature request to add support for synonyms when converting from dictunformat to slob, but when I upgraded from 4.2 to the latest version to make a testcase, I found that it broke the synonym handling for stardict format. Previously I was converting dictunformat -> stardict -> slob as a way to get dictunformat+synonyms into slob format.

cat <<EOF>test.dictunformat
_____
foo|foo1|foo2|foo3
This is a test
_____
bar|bar1|bar2|bar3
Another test
EOF

pyglossary-4.2.1 test.dictunformat test-4.2-1.ifo
pyglossary-4.3 test.dictunformat test-4.3.ifo

cat test-4.2.1.ifo

dictunformat tool uses "semi-colon and 3 spaces" by default to separate headword and alternates (You can change it with --headword-separator).

_____

foo;   foo1;   foo2;   foo3
This is a test
_____

bar;   bar1;   bar2;   bar3
Another test

I pushed a commit and made it the default behavior of PyGlossary to split with this separator.
I suggest you fix your files.
But if you still want to use |, use a command like this:

pyglossary test.dictunformat test.ifo --read-options 'headword_separator=|'
