Use neovim versions of ~/.vim and ~/.vimrc #44

wellle · 2014-02-22T14:15:16Z

Rename the following files and directories:

~/.vim     → ~/.neovim
~/.vimrc   → ~/.neovimrc
~/.gvimrc  → ~/.neogvimrc
~/.viminfo → ~/.neoviminfo

Close #26.

Coornail · 2014-02-22T15:15:12Z

Maybe we want to fall back to the original files in case the neo* files are missing.

What do you think?

jdiez17 · 2014-02-22T15:34:29Z

Agreed, there should be a fallback.

wlhlm · 2014-02-22T15:36:03Z

How about using n* instead of neo* to have more concise names?

felipecrv · 2014-02-22T15:43:15Z

Falling back to original files complicates things way too much. Instead of implementing the fallback we would be better off not even considering ~/.neovim files and just stick to the original names.

Imagine how puzzled the user will be if the ~/.vimrc configuration stops working just because an empty ~/.neovimrc was created.

The user can always symlink ~/.neovim to ~/.vim if it works for him.

sbeckeriv · 2014-02-22T15:44:16Z

Is there a way to push this in to the build or is that a bad idea? Have the default build script default to neovim and a release build that uses vim?

Coornail · 2014-02-22T15:54:03Z

I would prefer having one .vimrc in my dotfiles and both vim and neovim could pick it up (as it does now).

wellle · 2014-02-22T15:55:42Z

Falling back sounds like a good idea, but I agree that it would complicate matters.

If we are going to add settings and constructs to neovim that are not available in Vim, using the same configuration files will result in conflicts. So it might be a good idea to have this separation right from the start.

And if you don't want to have that separation you could still symlink ~/.neovim to ~/.vim.

I would also be fine with ~/.nvim instead of ~/.neovim.

On a more general note, are we planning to rename the executable at some point to avoid confusion with Vim?

ekosz · 2014-02-22T15:56:16Z

If the goal of neovim is to be a replacement for vim, it should be able to work off of the same vimrc. I don't think it should work off of a separate configuration file.

wellle · 2014-02-22T16:00:00Z

But isn't it also a goal to refactor it so it becomes easier to implement new features that are hard to add to Vim? Job control and the new plugin architecture are likely to introduce knobs that won't work in Vim.

sethwoodworth · 2014-02-22T16:07:14Z

There are decent conventions to conditionally configure plugins based on if they have loaded or not. Typically:

if (exists(":TagbarToggle"))
    let g:airline#extensions#tabline#enabled = 1 
en

I prefer (for now) a convention for people adding neovim specific config files of if (exists(":neovim")) blocks. I think this will ease development.

0X1A · 2014-02-22T17:14:59Z

I guess the question is whether neovim is really a replacement or a new implementation?

benbarbour · 2014-02-22T19:05:41Z

👍 @wellle. There's always -u and changing the runtimepath if you want to run both vim and neovim at the same time with different settings (which I imagine will be very desirable during testing neovim!), but keeping them separate just seems cleaner. Especially considering the strong possibility of neovim specific settings. Even if they're separate, it would be trivial to symlink them, or I would think .nvimrc could even source .vimrc, if desired.

It's not like changing the defaults paths will be very hard at any point in the project though.

ShaneDelmore · 2014-02-22T19:58:01Z

I agree with sethwoodworth, an environment variable allowing a conditional neovim block to run is an easier way to handle this.

sbeckeriv · 2014-02-23T01:20:29Z

@Peregrinati testing and development was my main thoughts when I requested this change #26 (comment)

@0X1A I understand it will be a replacement. I think a build for release would use vim vs noevim.

Will new features in this code base need exists(":neovim") code? Plugins/shared code will need it for sure.

jmkogut · 2014-02-23T08:55:07Z

@sethwoodworth I agree with you completely, let's use the original configuration files and set a global "is_neovim" or whatever.

afh · 2014-02-23T12:06:00Z

👍 on @sethwoodworth proposal for if (exists(":neovim"))

Olivia5k · 2014-02-23T12:37:43Z

exists(":neovim") implies that there is a command called neovim (invoked as :neovim). Instead, neovim should define a feature and use has(). See :he has() and :he feature-list.

tarruda · 2014-02-24T17:15:50Z

Merged, thanks

Added 'neovim' to the feature list, following discussion on #44
