:GoDoc seems to be in vi compatibility mode

[inlined]

What did you do? (required. The issue will be closed when not provided.)

Even when I add set nocompatible to my .vimrc, I'm having trouble with GoDoc. Whenever I hit an arrow key, it closes the :GoDoc window and adds a newline with the character associated with that arrow key.

What did you expect to happen?

For arrow keys to move the cursor work

What happened instead?

The GoDoc split closes, a new line in my original file is added, and it has the character associated with that arrow key.

vim-go maps <Esc> to close the godoc buffer. What I suspect is going on is that Vim doesn't recognize the escape codes for your arrow keys, so it sees <Esc>[B (or whatever your terminal sends).

This doesn't really sound like a vim-go problem, but more of a general issue with your Vim/terminal/system?

The same for me, :h vim-go, for example, works perfectly, while :GoDoc closes on every arrow key, pageup/pagedown, etc press.

I am also finding this after updating vim-go. Unfortunately the last time I updated was in June 2014, so there's a regression somewhere in that time period, but it's hard to narrow down (about 1900 commits).

This doesn't happen with Neovim. I've checked the code again go/autoload/doc.vim and there is nothing special we do. I think this has something to do with Vim & Term interaction (because NeoVim doesn't close the window when you use you arrow keys)

[dsymonds]

I did a git bisect, and f478b53 is the commit at which this starts failing for me. If I git reset --hard f478b53^ then I'm back to a vim-go with a working :GoDoc.

Thanks David, this is helpful. I'll look into it. I wonder what triggers this behavior.

[dsymonds]

Thanks for the fix. Arrow keys work now, but PageUp/PageDown are now broken. :-(
