Dotfiles

First Principle

Do not go out of ways how the default environments work.

There are many cases when I must work on foreign environments, and it is always VERY irritating when things do not work as I expected, yet setting up my own environment is troublesome. So I avoid changing behaviors of tools, except for emacs.

Emacs is the editor I usually use for coding. I decided to change the behavior of emacs as I want without thinking about other environments. When I cannot use my emacs.el I’ll use vi or vim instead.

Other tools like bash and vim basically work in the same ways even when using my rc files. The main changes are related to showing informations, typically in the bash prompt.

shrc.common

setup.sh will create file “$HOME/.shrc.common”. This file define some variables that can be used to detect system type. This file is sourced from both setup.sh and shrc.

Sourcing flow

1. $HOME/.profile

Sourced if:

• currnet shell is login shell and
  • (current shell is sh ||
  • (current shell is bash && $HOME/.bash_profile does not exist) ||
  • (current shell is zsh && $HOME/.zprofile does not exist))

This file set ENV to $HOME/.shrc , which is loaded when sh is run interactively. Add lines like test -n "$BASH_VERSION" && . "$HOME/.bashrc" .

2. $HOME/{.bash_profile,.zprofile} Sourced if current shell is login shell and shell is bash or zsh. Srouce $HOME/.profile .

3. $HOME/.shrc

Sourced through ENV when shell is sh, and $HOME/.{ba,z}shrc if bash or zsh respectively. Source $HOME/.dotfiles/shrc .

4. $HOME/.{ba,z}shrc

Sourced when current shell is bash or zsh respectively and current shell is not login shell. When current shell is login shell, these files are sourced explicitly by $HOME/.profile . Source $HOME/.shrc .
