more comprehensive ctags definitions for the julia language based on the one in the official julia repository (inclusive vim tagbar)

.vimrc

let g:tagbar_type_julia = {
    \ 'ctagstype' : 'julia',
    \ 'kinds'     : [
        \ 't:struct', 'f:function', 'm:macro', 'c:const']
    \ }

Note that these rules are specifically for use with the tagbar plugin.

They are not suitable for running ctags manually, as e.g. function arguments are included in the tag name. This works well for tagbar, but it doesn't allow you to jump to tags with ctrl+]
