Ubuntu Development Environment

This blog details the steps to configure and install my usual development environment on Ubuntu 20.04.

1. System Update

sudo apt update
sudo apt upgrade -y

2. Build Essential

sudo apt install build-essential -y
sudo apt install git -y

3. Terminal Tools

3.1. Terminator

sudo apt install terminator -y

3.2. Zsh

sudo apt install zsh -y  

Set zsh as default:

chsh -s /bin/zsh  

3.3. Oh my zsh

• Auto installation:

  wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | sh
  

• Manual installation:

  git clone git://github.com/robbyrussell/oh-my-zsh.git ~/.oh-my-zsh
  cp ~/.oh-my-zsh/templates/zshrc.zsh-template ~/.zshrc
  

• Modify preferences in ~/.zshrc, for example:
  • Change the theme:

    ZSH_THEME="ys"
    

  • Add plugins:

    plugins=(git zsh-syntax-highlighting zsh-autosuggestions)
    

  • Set aliases:

    alias ll='ls -la'
    alias gs='git status'
    

3.4. zsh-syntax-highlighting

• Clone the repository

  git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting
  

• Modify preference in ~/.zshrc

  plugins=(... zsh-syntax-highlighting)
  

• Validate it by reopening a terminator or source ~/.zshrc

3.5. zsh-autosuggestions

• Clone the repository

  git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions

5. git difftool: meld

sudo apt install meld -y
git config --global diff.tool meld
git config --global difftool.prompt false

To use meld as a git difftool, you can run meld in everywhere and git difftool in your repository to compare changes.

You can also use meld to compare specific commits or branches in your repository:

git difftool <commit1> <commit2>
git difftool <branch1> <branch2>
