homebrew the missing package manager for os x

first thing first

        $ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

usage

from http://brew.sh/
1. homebrew install the stuff you need that appble didn’t
```
 $ brew install wget
```
2. homebrew installs packages to their own directory and symlinks into /usr/local
3. homebrew won’t install files outside its prefix
4. it’s all git and ruby underneath
5. homebrew formula are simple ruby scripts

from tips n’ tricks

quickly remove something from /usr/local
```
 $ brew unlink formula
```

command tab-completion

 # add to ~/.bash_profile
 source $(brew --repository)/Library/Contributions/brew_bash_completion.sh

pre-downloading a file for a formula

 # download the file and drop it in
 # `/Library/Caches/Homebrew`
 # find cache folder
 $ brew --cache

 # homebrew downloads files as
 # `formula-version`

 # eg. erlang
 # `otp_src_R13B03` to `erlang-R13B03`

 $ mv the_tarball `brew --cache formula-name`

 # pre-cache the download
 $ brew fetch formula
 # also displays `sha1` and `sha256`

using homebrew behind a proxy

 # homebrew uses commands for downloading files
 # curl git svn
 # curl supports
 #      http_proxy
 #      HTTPS_PROXY
 #      FTP_PROXY
 #      GOPHER_PROXY
 #      ALL_PROXY
 #      NO_PROXY

 # `http_proxy` is enough
 $ http_proxy=http://<host>:<port> brew install formula

 # proxy authentication
 $ http_proxy=http://<username>:<password>@<host>:<port> brew install formula

 # this technique will also work with `sudo`
 # but `sudo` clears the environment
 # before executing homebrew
 # your proxy setting may get lost
 $ http_proxy=http://<host>:<port> sudo -E brew install formula

install stuff without xcode-clt

 $ brew sh
 $ gem install ronn

 # this imports brew env into your existing shell
 # gem will pick up the env variables
 # and be able to build

install only a formula’s dependencies

 $ brew install --only-dependencies formula

brew irb

 $ brew irb
 ==> Interactive Homebrew Shell
 Example commands available with: brew irb --examples

  ==> Caveats
  A "/etc/my.cnf" from another install may interfere with a Homebrew-built
  server starting up correctly.

  To connect:
      mysql -uroot

  To have launchd start mysql at login:
      ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents
  Then to load mysql now:
      launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
  Or, if you don't want/need launchctl, you can just run:
      mysql.server start
