I am unable to setup things for golang, new to helix

[icoderarely]

I seem to like helix editor but as a newbie have some issues that needs to be fixed and I tried but couldn't
I tried several reddits, helix guide itself, tried to copy helix snippets from languages.toml file none works as I expect them to.

1. auto-pairs dont seem to work
2. how do I enable code actions for golang?
3. how to keep undo/redo history saved like in neovim
4. anything you would recommend to have, please let me know

pasted this from languages.toml of helix itself, and the commented one was the one i was trying

Also one more this when i do hx --health i get some kind of warning like, runtime directory does not exists. Hope that's okay thing or not?

my hx --health | grep "go" results

1. Can you explain what you mean? Does it just not work at all for any pair? Have you also tried just the default config (it's baked into Helix, so no need to copy over the entire languages.toml)
2. You can execute code actions via C-a
3. There is an open PR: Vim-like Persistent Undo #9154

[icoderarely]

1. I mean if I type ( or " the editor should recommend me ) or " respectively, and similarly for other quotes and brackets. I did remove the languages.toml file now.
2. This seems to work, I have never used this feature anywhere so thought this also corrects things like fmtss to fmt, but I tried some other example and it seems to work fine.
3. I am not sure how I can use it :(

One more thing what is this?

the Finished loading packages thing...

[icoderarely]

1. solved, (yes didn't see that coming) had it changed to false in the config
2. solved [but not exaclty]
   
   over here it should have recommended to use brackets for fmt and math but it didn't, although if I tried explicitly looking for any code actions there was to do the same thing. But I expect a red line or auto format these.
3. need some help here still

And what was that loading packages thing

[kirawi]

Since persistent undo is a PR, it means the feature is still under development. It's buggy and not ready for testing either.
