Not going to lie to you: this post is not any better than googling “cypher syntax highlighting for vim.” In fact, that might be a better thing for you to do! But since you’re already here–

# Assuming you have Pathogen installed...
cd ~/.vim/bundle
git clone git://github.com/neo4j-contrib/cypher-vim-syntax.git
cd ~/YourCypherProject/
vim hello-world.cypher

Consider your syntax highlighted:

CREATE (hello:World {greeting: "Earthlings!"})
RETURN 'Aloha '+hello.greeting

…in Vim, but not on GitHub :-(

Oh GitHub, why hast thou forsaken me! (Relevant music plays in the background, reminding the world that System of a Down needs to put out a new album already: “Forsaken me. Forsaken me. Forsaken. Me–! Oh, I— cry— when angels deserve to die!”)
