Installing Neovim
25 Nov 2014Update: This isn't necessarily up to date any more. Check the Neovim wiki for the most up-to-date instructions.
Neovim has been moving along quite steadily over the last six months, and it's finally starting to hit a level of stability where I feel comfortable using it full-time. I did have to jump through a few minor hoops to get it working, however:
Homebrew
I use Homebrew to handle my dependencies, as you'd expect, so this was the first thing I tried:
brew tap neovim/neovim
brew install neovim --HEAD
Unfortunately it failed with an unknown error and ate my error logs before I could view them. On to the next method!
Installing by hand
The instructions claim that this command will install the required Luarocks modules:
make CMAKE_EXTRA_FLAGS="-DCMAKE_INSTALL_PREFIX:PATH=$HOME/neovim" install
But I ended up having to install them by hand:
brew install luarocks
luarocks install lpeg
luarocks install lua-messagepack
luarocks install luabitop
# for tests
luarocks install busted
Once that was done I could correctly run the above command:
make CMAKE_EXTRA_FLAGS="-DCMAKE_INSTALL_PREFIX:PATH=$HOME/neovim" install
Making plugins work
I use quite a few plugins to make some boring tasks easier, and Vundle to manage them. Luckily moving them over was a very simple matter:
cp ~/.vimrc ~/.nvimrc
pip install neovim
Tmux navigation
This is what my old .tmux.conf file looked like:
bind -n C-h run "(tmux display-message -p '#{pane_current_command}' | grep -iqE '(^|\/)vim(diff)?$' && tmux send-keys C-h) || tmux select-pane -L"
bind -n C-j run "(tmux display-message -p '#{pane_current_command}' | grep -iqE '(^|\/)vim(diff)?$' && tmux send-keys C-j) || tmux select-pane -D"
bind -n C-k run "(tmux display-message -p '#{pane_current_command}' | grep -iqE '(^|\/)vim(diff)?$' && tmux send-keys C-k) || tmux select-pane -U"
bind -n C-l run "(tmux display-message -p '#{pane_current_command}' | grep -iqE '(^|\/)vim(diff)?$' && tmux send-keys C-l) || tmux select-pane -R"
This is what my new .tmux.conf file looks like:
bind -n C-h run "(tmux display-message -p '#{pane_current_command}' | grep -iqE '(^|\/)(n)?vim(diff)?$' && tmux send-keys C-h) || tmux select-pane -L"
bind -n C-j run "(tmux display-message -p '#{pane_current_command}' | grep -iqE '(^|\/)(n)?vim(diff)?$' && tmux send-keys C-j) || tmux select-pane -D"
bind -n C-k run "(tmux display-message -p '#{pane_current_command}' | grep -iqE '(^|\/)(n)?vim(diff)?$' && tmux send-keys C-k) || tmux select-pane -U"
bind -n C-l run "(tmux display-message -p '#{pane_current_command}' | grep -iqE '(^|\/)(n)?vim(diff)?$' && tmux send-keys C-l) || tmux select-pane -R"
All I've done is add the (n)? prefix to the grep pattern (and reloaded the
conf file via tmux source-file ~/.tmux.conf).
Conclusion
Everything works, and it seems snappier. I'm excited, and I'll post some more details when / if I encounter any more problems.
