Essential Environment Setup
iTerm
Let's start with installing iTerm.
Please visit https://iterm2.com then download and install it.
Install color themes
Visit https://iterm2colorschemes.com and download the zip or tar.gz and extract it.
Follow the installation instruction.
e.g.)
Homebrew
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
zsh (Z shell)
macOS's default shell is z-shell, so you don't need to install it.
To check the default shell
echo $SHELL
You should see something like
/bin/zsh
Oh My Zsh
Install Oh My Zsh.
sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
Font for Coding
brew tap homebrew/cask-fonts
FiraCode
brew install --cask font-fira-code
For nerd font,
brew install --cask font-fira-code-nerd-font
Microsoft Cascadia Code
brew install font-cascadia-code-pl
For nerd font,
brew install --cask font-caskaydia-cove-nerd-font
JetBrains Mono
brew install font-jetbrains-mono
brew install font-jetbrains-mono-nerd-font
Dot Files (WIP)
You can keep all aliases, environment variables and functions in ~/.zshrc but as the file gets bigger, it would be hard to maintain it. So it would be a good idea to put them in to multiple files depending on their relevance.
mkdir -p ~/.my-dot-file
echo 'if [ -f ~/.my-dot-file/.all_my_rc ]; then
. ~/.my-dot-file/.all_my_rc
fi' >> ~/.zshrc
Now you can have multiple .some_rc files in ~/.my-dot-file and load them in the ~/.my-dot-file/.all_my_rc so that ~/.zshrc can load them all.
TBD
Oh My Posh
brew install jandedobbeleer/oh-my-posh/oh-my-posh
To be added...
Other Tools
git
brew install git
exa
exa is a modern replacement for ls written in Rust.
brew install exa
Once installed, you can replace ls with exa by adding aliases like.
if type exa >/dev/null 2>&1; then
alias ls0='command ls -G'
alias ll0='ls0 -l'
alias l0='ls0 -al'
alias ls='exa'
alias ll='ls --color-scale -lh'
alias l='ls --color-scale -lah'
else
alias ls='ls -G'
fi
Now you ls is exa. ls -l can be done by ll and ls -a is just l.
You can still use ls by running ls0 (but why?! 🤔)
curl
brew install curl
wget
brew install wget
fd
brew install fd
grep
brew install grep
htop
brew install htop
HTTPie
HTTPie is a simple and intuitive http client CLI tool similar to curl. httpie now has a desktop app as well.
brew install httpie
It installs http and https.
Try the following command to test,
https httpie.io/hello
bat
bat (🦇) is an alternative to cat (🐈) with syntax highlighting and Git integration.
brew install bat
Let's compare bat with cat.
First cat,
Now, bat,
delta
delta is a syntax-highlighting pager for git.
brew install git-delta
Once installed, add delta to ~/.gitconfig
[core]
pager = delta
For more about delta configuration, please visit the delta user manual.
FYI, this is what I have in my ~/.gitconfig.
[core]
pager = delta
[interactive]
diffFilter = delta --color-only
[delta]
navigate = true
side-by-side = true
features = line-numbers decorations
syntax-theme = Monokai Extended Bright
plus-style = syntax "#003800"
minus-style = syntax "#3f0001"
[delta "decorations"]
commit-decoration-style = bold yellow box ul
file-style = bold yellow ul
file-decoration-style = none
hunk-header-decoration-style = cyan box ul
[delta "line-numbers"]
line-numbers-left-style = cyan
line-numbers-right-style = cyan
line-numbers-minus-style = 124
line-numbers-plus-style = 28
Now the result of git diff may look like this.
procs
procs is a modern alternative to ps.
brew install procs
e.g.)
$ procs
