Feature request: text-based auto-completion

[xJonathanLEI]

I'm trying to daily drive with Helix but find myself missing the (current buffer / opened buffers) text-based auto-completion feature from neovim a lot.

The best thing about text-based (vs. LSP) auto-completion is that it's super fast and has no dependency. It can be very helpful when:

• the LSP is not installed (or not supported)
• I just wanna make a quick edit, and don't want to wait for the LSP to initialize (especially ones with slow startups like rust-analyzer?)
• even when the LSP is initialized, sometimes it takes a while to reflect code changes, and it's faster to just get text-based suggestions if I'm familiar with the codebase I'm editing

Lacking this feature, I have to do a lot of find-yank-replace instead of just typing out the first letters and selecting from the suggestions. This is especially bad in dynamic languages since a typo may not be detected until runtime, making the user more cautious and always opt for find-yank-replace.

I'm pretty certain this has been requested (or even already implemented) before, but I can't find anything relevant from the issues. Sorry for spamming if that's the case. Would love a pointer to the relevant issue. Thanks!

Ah "lexical" is the keyword. Thanks!
