Validate typos in the dictionary against a dictionary of valid words

[peternewman]

We'll need to find a list of valid words from somewhere, but this keeps happening to varying degrees of detectability, e.g. #1014 (comment)

[peternewman]

In my scripts, before to insert a couple "a->b" in my list, I check them against the usual historycal dictionaries you can find on Unix (like /usr/share/dict/american-english). But of course, there are a lot of specific (and not so specific...) words not included.

If you have aspell installed, you can dump the aspell wordbook.
aspell -d en dump master | aspell -l en expand > words.en.txt

I checked (the probably outdated version of debian stable) with codespell. It results in

[peternewman]

Thanks for this @sebweb3r . As you may have seen we got some core stuff in via #1142 . I'm not quite sure what my "other examples need checking" comment meant with regards not closing this issue then.

I'm a bit unclear which way your checks have been done. Is this Codespell run against aspell and hunspell's dictionaries?

Also

-seledted->sekected
+seledted->selected

Sorry for not being precise. I've dumped the aspell and hunspell dictionaries. Then, I've checked the dumbs with codespell.

So all of these lines are words, that are "wrong" in codespell, but exist in aspell or hunspell.

But I'm not sure, if one wants to delete all of the corrections.

[sebweb3r]

I haven't seen #1142 yet, but I will have a closer look.

[lurch]

Going the other way around, and running aspell against codespell's correct-words (generated with cat dictionary.txt | cut -d'>' -f2 | sort | uniq > codespell_corrections.txt) also suggests:

• acrued->accured should be acrued->accrued
• acknodledgment->acknowledgment should be acknodledgment->acknowledgement
• acknoledgment->acknowledgment should be acknoledgment->acknowledgement
• aquries->acquries should be aquries->acquires
• adjacentcy->adjacence should probably be adjacentcy->adjacency, adjacence, ?
• affinitied->affinitized should probably be affinitied->affinities, affinitized, ?
• asymetri->assymetry should be asymetri->asymmetry (and could be asymetri->asymmetric, asymmetry,)

(And possibly many more? I got bored of checking... 😉 (as there are many entries in codespell that aspell doesn't recognise, but a Google search suggests are still spelled correctly) )

If codespell is going to suggest corrections, those corrections ought to be spelled correctly 😀

[sebweb3r]

@lurch that's why I never let spellcheckers automatically fix the errors.
I basically checked the correct spellings in #1624 already (against aspell-enUS dict) ;-)
I added some of your suggestions.

acknowledgment depends on enUS or enGB #1623 (One of the physics journals insists on using the variant without e. But they have both spellings on their introductions webpage :-) )

[lurch]

acknowledgment depends on enUS or enGB

Ooops, I didn't realise that it had multiple spellings (like color / colour), sorry!

I added some of your suggestions.

Cool 👍

[peternewman]

So I added some checking, but we need #1485 to have a larger dictionary and fewer false positives, or we need to split the main dictionary and rare into corrections that are in the dictionary and those that aren't, so we can prioritise more carefully checking the non-dictionary words. Currently it doesn't check the corrections as lots of valid technical terms aren't in the aspell word list.

[DimitriPapadopoulos]

@peternewman Words not in aspell dictionary can be added after #2933. Such words need to be whitelisted because some specialised words will be missing from the aspell or other dictionaries, no matter how large the dictionary is. Can we close this issue?
