使用 rbenv 安装和管理Ruby版本

常用的几个 Ruby 版本管理工具有:rvmrbenv,ry,rbfu。rvm 应该是最早出现、使用最多的,因为过于强大以至于违背了某个 Linux 软件开发原则,所以出现了很多轻便的替代者,其中来自 37signals 的 rbenv 就很受欢迎。ry 和 rbfu 看上去更轻便,不过使用不广泛。之前使用过rvm, 这次尝试下rbenv。

我的环境是 Ubuntu14.04

1. 安装 rbenv

rbenv的源代码托管在github,在终端中,从 github 上将 rbenv 源码 clone 到本地,然后设置 $PATH。

git clone git://github.com/sstephenson/rbenv.git ~/.rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc

True Colour (16 million colours) support in various terminal applications and terminals

Colours in terminal

It's a common confusion about terminal colours... Actually we have this:

  • plain ascii
  • ansi escape codes (16 colour codes with bold/italic and background)
  • 256 colour palette (216 colours + 16 ansi + 24 gray) (colors are 24bit)
  • 24bit true colour ("888" colours (aka 16 milion))
printf "\x1b[${bg};2;${red};${green};${blue}m\n"
