Update ctags with brew

The “ctags” coming with Mac OS is really a very old one (1993). We can update it with brew, and I think this Article is very useful.

The point is:

  • Install latest ctags with brew: brew install ctags. This should be OK
  • Replace “ctags” with:
    1. alias ctags=”brew --prefix/bin/ctags”
    2. alias ctags » ~/.bash_profile
    3. Please note that the original post uses ~/.bashrc but it won’t work in Mac OS. So use ~/.bash_profile instead

brew --prefix will display the install path of brew, and append it with /bin/ctags will get the new ctags pathname. Please note that “`” is the character with the key “~” on your keyboard.
