WSL - Set Up Distro¶

Set up basics¶

Update distro¶

update => updates the database of packages (list of versions etc)
upgrade => actually updates the packages
Hence first run update to get a fresh list and then run upgrade to update the packages
Note : You can use apt install -y PACKAGE_NAME to assume a "yes" answer to any prompts

sudo apt update && sudo apt upgrade

Tools¶

Zsh
sudo apt install zsh
Set up Zsh and set it as the default shell
Run zsh and follow instructions
To get back to this menu:
autoload -Uz zsh-newuser-install
zsh-newuser-install -f
Oh-my-zsh
- download it via curl as per instructions on project page
  sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
- follow instructions
Install powerline fonts if needed for Oh My Zsh themes, etc sudo apt install powerline fonts-powerline
Midnight Commander
sudo apt install mc
Git : update git to latest version
- First add Git maintainers' PPA:
  sudo add-apt-repository ppa:git-core/ppa
- Then update repository directory:
  sudo apt update
- Finally, 'install' git to get the updated version (even if it was already installed)
  sudo apt install git
Tree
sudo apt install tree
Fix the directory background on the ls command.
Add the following to .bashrc or .zshrc

# FROM : https://github.com/lloydstubber/my-wsl-setup#fix-the-ls-and-cd-colours
#Change ls colours
LS_COLORS="ow=01;36;40" && export LS_COLORS

Git¶

Use Ubuntu/WSL Git for cloning repos (e.g. some cli apps are installable via Git)
Use the Git from Windows to manage my own repos
Install Git for Windows.org
Install Git Credential Manager
When working with GitHub repos, the Git Credential Manager will *magically* kick in and manage the credentials.

Other Stuff¶

Set a symlink/mount point to a working directory in windows
sh # move to home directory cd # set symlink to working folder ln -s /mnt/c/bin
Set a setup file to save all installed items & to easily set up a new distro

# set up wsl setup file  
touch wsl_setup.sh

# give it execute permission
chmod 755 /mnt/c/wsl_setup.sh

# to edit it with VS Code
code wsl_setup.sh 

# to send commands to the wsl_setup.sh file, example:
echo "sudo apt install mc #install midnight commander" >> wsl_setup.sh

Set up for Python¶

Pyenv¶

Dependencies for pyenv
- Supposedly this is only required if installing from source (downloading Git repo & building)
- However on my Ubuntu 18.04 (LTS) in WSL the Python build failed, so I installed the dependencies as described here :
  sudo apt-get update; sudo apt-get install --no-install-recommends make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev xz-utils tk-dev libxml2-dev libxmlsec1-dev libffi-dev liblzma-dev
Use the installer script from the installer project Pyenv Installer curl -L https://github.com/pyenv/pyenv-installer/raw/master/bin/pyenv-installer | bash
or
curl -L https://github.com/pyenv/pyenv-installer/raw/master/bin/pyenv-installer | zsh
Add pyenv to the load path (add the following lines to .zhrc or .bashrc)

export PATH="/home/ska2/.pyenv/bin:$PATH"
eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"

Restart the shell
exec "$SHELL"

Python Interpreter¶

To check available Python interpreters for installation, run :
pyenv install --list
Install the interpreter required, e.g. for 3.8.2 run :
pyenv install 3.8.2
Set the global Python interpreter if required :
pyenv global 3.8.2

Python Project Environment¶

This is standard Pyenv stuff:

Create a virtualenv : pyenv virtualenv 3.7.7 MYENVNAME
Then activate it pyenv activate MYENVNAME
Or : Go to directory and do pyenv local 3.7.7 and create a virtualenv there
