I use gvim with julia-vim for editing julia code. I am using julia 0.5 on a mac and installed julia-vim with vundle.
My problem is that files with the .jl
I found that the instructions here worked a treat. Namely
git clone git://github.com/JuliaEditorSupport/julia-vim.git
mkdir -p ~/.vim
cp -R julia-vim/* ~/.vim
Note: I realise that the OP claims to have already installed Julia-Vim using Vundle, but I came to this question because Vim was automatically using LISP syntax highlighting for me, and the above was enough for me. So I am sharing in case anyone comes from the same boat as me (i.e. the problem is not Vundle related) :)
