nimsuggest: case insensitivity support

[Akronae]

Summary

Supporting different case types is something that is really bragged on about Nim, but in reality it is impossible to conveniently code using snake_case as nimsuggest/std lib is totally opiniated to camelCase.

How about not having to configure anything at all but just nimSuggest infering your coding style from your input ?

Seems simple enough, I'm pretty new to Nim though maybe there is something I'm overlooking.
I would be interested to contribute.

Description

This would fix the currently very unstable coding experience of people taking advantage of Nim's partial case insensitivity.

Alternatives

No response

Examples

I have a module A with a proc myProc
if I type A. nimsuggest will suggest me A.myProc
if I type A.my_ nimsuggest will suggest A.my_proc

A more advanced flavor would be for nimsuggest to look backward and check wether I used snake_case for other identifiers and suggest straight away A.my_proc while still suggesting A.myProc if I type A.myP

Seems to be a good idea.

Would like to contribute and see if I can draft a PR, is there anything I should do to get onboarded, or can I start straight away?

Yeah, go for it! It's yours!

I'm having a really hard time trying to make my dev environment work.

Just cloned the repo, and compiled from sources with

bash build_all.sh

If I try to interact with nimsuggest using a relative path it works fine

./bin/nimsuggest --stdin --debug --v2 nim.nimble
> sug compiler/suggest.nim 185 1

But if I add ./bin to my path, then by asking sug compiler/suggest.nim 185 1 to nimssugest, I get a segfault, yet I did not change any source.

My guess is that by adding ./bin to my path, one of these tool is called by nimsuggest, and is not really working well

When not adding ./bin to my path, my nimsuggest that has been built is calling tools from my Nim Homebrew installation.

I'm a bit lost, any idea?
