Zulu dictionary hangs browser

[dbolton]

var dictionary = new Typo("zu_ZA", affData, dicData);
var is_spelled_correctly = dictionary.check("hamba")

browser hangs when loading the dictionary (sometimes it gives an alert asking if you want to stop the script)

I used the Zulu dictionary and affix files provided by OpenOffice.org and Mozilla
https://addons.mozilla.org/thunderbird/downloads/latest/46490/addon-46490-latest.xpi?src=addondetail
(if you change the .xpi file extension to .zip you can decompress the files)
(here's the source page: https://addons.mozilla.org/en-US/thunderbird/addon/zulu-spell-checker/ )

Probably related to the 2,200 affix rules; the English dictionary only has ~200.

Can I ask what kind of project that you're working on that is allowing you to discover these bugs?

Actually, it looks like that specific Zulu .dic file also contains the entire .aff file at the end, probably by accident. If you remove that, the dictionary loads without freezing the browser (although it does take a while due to the size of the legitimate dictionary).

I'm creating a spell checker that works with music lyrics. No notation software I'm aware of has a spell checker. JavaScript is the language I'm most comfortable with (and excellent at parsing MusicXML files), so I was excited when I read your blog post.

Initially I was hoping to post the spell checker on the web, but the size of the dictionary files make that less practical (at least in it's current form since it loads the dictionary files every time you open a MusicXML file to check the spelling of the lyrics).
