Git

Git is one of the most popular version control systems. It comes pre-installed on macOS. However, Apple's bundled version of Git is not as well-maintained as the official Git repo.

Installation

  1. Make sure you have installed Homebrew on your system - if not, read the Homebrew guide;

    which brew

  2. Open terminal and run the following command:

    brew install git

  3. Verify git has been installed.

    git --version

Configuration

  1. Set Git editor;
git config --global core.editor "nano"
  1. Set Git default push behaviour;
git config --global push.default simple
  1. Set Git user;
git config --global user.name "Your Name"
git config --global user.email you@example.com

Git completion in bash

Ignore this section if you are NOT a bash user.

  1. Create configuration files;

    touch ~/.bash_profile
touch ~/.git-completion.bash
touch ~/.git-prompt.sh

  2. Populate .git-completion.bash with https://github.com/git/git/blob/master/contrib/completion/git-completion.bash;

  3. Populate .git-prompt.sh with https://github.com/git/git/blob/master/contrib/completion/git-prompt.sh;

  4. Update permissions of .git-completion.bash and .git-prompt.sh;

    chmod 755 ~/.git-completion.bash
chmod 755 ~/.git-prompt.sh

  5. Populate .bash_profile, as follows:

    #!/bin/bash

export PATH="/usr/local/bin:$PATH"

source ~/.git-completion.bash
source ~/.git-prompt.sh

MAGENTA="\[\033[0;35m\]"
YELLOW="\[\033[0;33m\]"
BLUE="\[\033[34m\]"
LIGHT_GRAY="\[\033[0;37m\]"
CYAN="\[\033[0;36m\]"
GREEN="\[\033[0;32m\]"
GIT_PS1_SHOWDIRTYSTATE=true
export LS_OPTIONS='--color=auto'
export CLICOLOR='Yes'
export LSCOLORS=gxfxbEaEBxxEhEhBaDaCaD

export PS1=$LIGHT_GRAY"\u@\h"'$(
    if [[ $(__git_ps1) =~ \*\)$ ]]
    # a file has been modified but not added
    then echo "'$YELLOW'"$(__git_ps1 " (%s)")
    elif [[ $(__git_ps1) =~ \+\)$ ]]
    # a file has been added, but not commited
    then echo "'$MAGENTA'"$(__git_ps1 " (%s)")
    # the state is clean, changes are commited
    else echo "'$CYAN'"$(__git_ps1 " (%s)")
    fi)'$BLUE" \w"$GREEN": "

alias ll='ls -lah'
alias gg='git status -s'

Please note: You need to restart your terminal for the settings to take effect.
