Add/change hyphenation rules?

[Martin Koistinen]

Greetings,

Firstly, many thanks for putting this PyHyphen together.  Very useful!

I'm writing because I'm seeing some head-scratching behaviour.  In particular, the word 'calculator' never seems to get hyphenated, even though other words around it are, including shorter words.

Initially I figured OfficeLibre’s hyphenation dictionary must just be lacking that word, but once I DL'ed and installed OfficeLibre, I find that OL hyphenates that word just fine.  So... I'm struggling to understand why I cannot get it to hyphenate in my project.

Is there a way to augment the dictionary with my own words such that I can continue to use the existing en-US hyphenation dictionary (and any future updates of the same) but at the same time use project-specific words too?  It isn't clear to me how I might do that.

Any tips greatly appreciated!

Hi,

on my machine, 'calculator' is hyphenated correctly as follows (win32, P2.7.5, PyHyphen 2.0.4):


In [2]: from hyphen import Hyphenator

In [3]: h=Hyphenator()

In [4]: h.pairs(u'calculator')
Out[4]: [[u'cal', u'culator'], [u'calcu', u'lator'], [u'calcula', u'tor']]

If you want to apply multiple hyphenators, e.g. to use your own dictionaries on top of an existing one, you could simply create a list of hyphenators and write a function that applies these successively to a given word until one of the hyphenators in the list returns a positive result.

OK, it turns out that ever case of the word 'calculator' in my document is followed by a full stop. I suspect that the hyphenator doesn't hyphenate words at the end of a sentence, perhaps to prevent widows.

Thanks for the reply!
