Feature request : Adding words to the dictionary at runtime

[gweltou]

Hi,

I used to work with pyhunspell (which doesn't seem to be maintained anymore), then with cyhunspell (which is currently broken on Python >=3.10).

I'm now trying to switch to Spylls but there is one critical feature that I miss : the ability to add words to the loaded dictionary at runtime.

There doesn't seem to be any function for that in the documentation or the source code. Is there a plan to add this feature in the future ?

Thanks a lot !

@gweltou Truth be told, I didn’t really expect to see spylls much used in production; I built it as educational material about how the classic spellchecker works. This is why it lacks some of the more “pragmatic” features that don’t affect the base principles.

I don’t expect to actively develop it further, for reasons both professional (what is said above) and personal (I am serving in the Ukrainian army currently); but I probably have enough capacity to accept PRs.

This being said, adding word to the dictionary can be achieved by exploiting internal APIs, though I can’t say it is convenient:

from spylls.hunspell import Dictionary

dictionary = Dictionary.from_files('internal/dictionaries/en_US')

from spylls.hunspell.data.dic import Word
from spylls.hunspell.algo.capitalization import Type

print(dictionary.lookup('Hogwarts')) #=> False

word = Word('Hogwarts', flags=set(), data={}, alt_spellings=[], captype=Type.INIT)
dictionary.dic.append(word, lower='hogwarts')

print(dictionary.lookup('Hogwarts')) #=> True

As APIs are internal, they expect a lot of arguments pre-calculated by the corresponding processes, but I assume that reusing those APIs, a reasonable public Dictionary.append('word', like='other_word') (common for various Hunspell wrappers) can be achieved.

Thank you for your answer ! I can definitely work with that !

Just wanted to mention that I came down the route @gweltou mentioned, so I think there is still a need there for those looking for hunspell on modern versions of python.

The greatest respect for your service, of course (I was glad to read you are still around this year).
