CTAGS Installation

To install the exuberant ctags (required for the taglist and the tagbar plugins) in OS X:

download the compressed file (or the latest version): http://sourceforge.net/projects/ctags/files/ctags/5.8/ctags-5.8.tar.gz/download
tar xzvf ctags-5.8.tar.gz
cd ctags-5.8
./configure
make Normally you should execute a "make install", but 2 errors will spawn. Do the followings:
Duplicate the directory ctags-5.8 to ctags
sudo cp ctags /usr/local/bin/ctags
sudo chmod -R 755 /usr/local/bin/ctags
sudo cp /usr/local/bin/ctags/ctags.1 /usr/local/share/man/man1/ctags.1
sudo chmod 644 /usr/local/share/man/man1/ctags.1
make install (should work without errors) Now you have to override the ctags that comes with OS X
put 'export PATH="/usr/local/bin/ctags:$PATH"' in your .bash_profile
restart the terminal
which ctags should return "/usr/local/bin/ctags"

How to keep the ctags up-to-date (from http://tbaggery.com/2011/08/08/effortless-ctags-with-git.html):

Execute:

git config --global init.templatedir '~/.git_template' mkdir -p ~/.git_template/hooks
Create .git_template/hooks/ctags and mark as executable:

#!/bin/sh set -e PATH="/usr/local/bin:$PATH" dir="git rev-parse --git-dir" trap 'rm -f "$dir/$$.tags"' EXIT git ls-files |
ctags --tag-relative -L - -f"$dir/$$.tags" --languages=-javascript,sql mv "$dir/$$.tags" "$dir/tags"
Create .git_template/hooks/post-commit and mark as executable:

#!/bin/sh .git/hooks/ctags >/dev/null 2>&1 &
Create .git_template/hooks/post-merge and mark as executable:

#!/bin/sh .git/hooks/ctags >/dev/null 2>&1 &
Create .git_template/hooks/post-checkout and mark as executable:

#!/bin/sh .git/hooks/ctags >/dev/null 2>&1 &
Create .git_template/hooks/post-rewrite and mark as executable:

#!/bin/sh case "$1" in rebase) exec .git/hooks/post-merge ;; esac
Use git init in existing repositories to copy these hooks in.

The tags file is located at PROJECT_ROOT/.git/tags

Configure the agnoster prompt to display only the user name

    fi 
}
