GemfileでOSの判別をする

More than 5 years have passed since last update.

「Macで開発してる時はgrowlのGem欲しいけど、本番環境はLinuxだしgrowlいらねぇ!」とかそういう時に役立つTips。

gem 'growl' if `uname` =~ /Darwin/

これで良し。

Macな人限定は試しにシェルで

uname

ってやってみると、Darwinって出るよ。

LinuxだとLinuxって出るよ。

追記

コメント欄より、

unameだとWindowsで使えないし、RUBY_PLATFORM を使おうとのこと。

gem 'growl' if RUBY_PLATFORM.match(/darwin/)

こんな感じ?
