Test cases

1. idefault<Tab><CR><Esc>

   Expected:

   from collections import defaultdict
   
   defaultdict

   Actual:

   from collections import defaultdict
   
   default

2. idefaultdict<Esc>Icollect<Tab><CR>.<Esc>

   Expected:

   import collections
   
   collections.defaultdict

   Actual:

   import collections
   
   collectdefa.ultdict

3. iimport collections<CR><CR>defaultdict<Esc>Icollect<Tab><CR>.<Esc>

   Expected:

   import collections
   
   collections.defaultdict

   Actual:

   import collections
   
   collections.

4. ihello<CR>hello<Esc>*cgnimp<C-n><CR><Esc>.

   Expected:

   import
   import

   Actual:

   import
   imp

I think the first two only happen in new and empty files. The third and fourth ones are the important ones since they happen very often in non-empty files.

thank you this is gonna be next PR

[ms-jpq]

i think most of the issues come from the fact that I I didn't write my code to handle multiple edits on the same line, which happens for 1) and 2).

the . one might not be doable, at least not without hampering fuzzy searching

[ms-jpq]

https://github.com/ms-jpq/coq_nvim/pull/130 fixes 1) and 2), but the . still needs investigating

[dtomvan]

If I complete anything (including snippets), coq spits out complete nonsense. Help?

[ms-jpq]

please post a screenshot, i dont know what do you mean by that

@dtomvan It might be better to create a new issue since it might not be related to these.

Im’ma make a GIF in a new issue.

Edit: in a couple of hours

This is https://github.com/ms-jpq/coq_nvim/issues/34?

Okay, now I have this output. My coq install seems very broken.

Edit: my configs: https://github.com/dtomvan/.config Edit: I changed my configs to temporarily not include any auto pairs plugin. coq just lags out when I try to use it tho.
