How to configure oh-my-zsh on Windows

There are 2 major ways to install oh-my-zsh in Windows: With WSL / without WSL.
Installation with WSL

WSL (Windows Subsystem for Linux) is a Windows feature that lets developers run a GNU/Linux environment -- including most command-line tools, utilities, and applications -- directly on Windows, unmodified, without the overhead of a traditional virtual machine or dual-boot setup.

You can use the WSL2 which is faster than v1. After the installation - you can install Ubuntu (a Linux distribution) from the Windows app store. Just follow the official guide.
I tried it for a while. You get the benefit of full Linux distribution inside Windows.
Some things to notice

  • You have 2 file systems. The subsystem files can be accessed differently via local network drive / command line. It's less convenient for me to get those files from the Linux system - instead of one single system. The paths are different.

  • You use your windows apps and install some command line packages in the Linux side. Your code is stored in the Linux environment.
    VSCode and Webstorm that are installed on your Windows can read/write your files from the Linux environment.

  • Every package you want to access with your Linux system's command line - should be installed on the Linux system. So this make you install tools like git, Node.js, Yarn and global packages on the Linux side too. If you want to develop sometimes on windows and sometimes on Linux - you will get some duplications.

    • Why I don't use WSL2 anymore
    I tried to use WSL2 for a while, but then I notice a major problem: my dev server did not notice file changes. Tools like nodemon, hot-module-replacement and fast refresh did not work. It turns out that there is a open issue:

    [WSL2] File changes made by Windows apps on Windows filesystem don't trigger notifications for Linux apps #4739

    WSL2 is really close to being a perfect runtime environment for server apps being developed in Windows. Great job! One missing feature however is breaking a core part of the developer flow.

    For sources stored on the Windows filesystem, any changes made by Windows applications such as Visual Studio do not trigger any file change notifications as far as Linux apps are concerned. This means that all "live rebuild"-type tools don't work (examples: webpack --watch, jekyll --interactive, and Tilt.dev) when running under WSL2. This unfortunately renders many modern dev workflows unviable.

    Notes:

    • I strongly expect this is already a known issue as hinted here. However I was unable to find any open GitHub issue that specifically tracks this. #1956 is about a different scenario, #4064 isn't specifically about change notifications, #4224 is closed, #4293 doesn't fix it.
    • I'm aware the WSL team suggests that with WSL2 it's good to store your application sources inside the Linux filesystem instead of the Windows one. However I don't think that's a viable solution since the whole point of WSL (for me) is to be able to use Windows-based editors such as full VS with a Linux dev environment. If it was sufficient to use Linux-based editors, I'd just use Mac/Linux as my actual OS and would have no need for WSL.
    • This did work great on WSL1
    • Changing fs.inotify.max_user_watches doesn't affect this, since the issue is about changes originating on the Windows side.

    Bug report template

    • Your Windows build number: 10.0.19033.1

    • What you're doing and what's happening:

      This applies to all tools that listen for file change notifications, but as an example take webpack. Repro steps:

      • In your Windows filesystem, create an empty directory (example: c:\repro), and then add these three files to it
      • In a WSL2 Ubuntu 18.04 environment, install Node and NPM: sudo apt-get install nodejs npm
      • Still in WSL2, go into the directory from earlier: cd /mnt/c/repro
      • Restore NPM dependencies: npm i
      • Run Webpack in watch mode: npm run build:watch. Wait a few seconds until it completes the first build. It will now be waiting for further changes to your source files.
      • In a Windows application (e.g., Notepad or Visual Studio), open c:\repro\index.js and save some change to it. For example, change 'Hello, world' to 'Hello, world 2'.

    • What's wrong / what should be happening instead:

      Expected behavior: Webpack should see the change and rebuild. That is, you'll see it log information about another build, and the output in dist/bundle.js will be updated.

      Actual behavior: Webpack doesn't respond at all, because there's no file change notification.

    Finally I understand that the fix for this is likely to be "add file watch capabilities to the Plan9 server", and you may feel this is already being tracked by #4064. However #4064 describes a more obscure symptom of this missing feature and makes it sound like an intermittent issue. What I'm reporting here is not intermittent at all, and is a pretty mainstream scenario (using tools like webpack --watch). Thanks!

    Some of those problems have workaround with polling instead of file watching. I try the polling approach with vite, but the experience was poor compared to vite regular fast refresh. This was BLOCKER issue for me so I removed WSL2.
    Installation without WSL2
    Install Cygwin

    Cygwin is a large collection of GNU and Open Source tools which provide functionality similar to a Linux distribution on Windows.

    This part of the post is based on zinox9's excellent post
  • Download Cygwin from it's website and run the installer.
  • Make Sure to Let the installer install at C:\cygwin64
  • For Download site Select Any URL , Click Add
  • STOP at packages screen, search wget expand All under Web select latest version of it under bin of wget no need to select Source. Then Continue. Cygwin wget Screen

  • Finish Installing and launch the Terminal.
    We are going to use Cygwin to Install Some Packages that will help to use Linux System on Windows. We will install apt-cyg which will work like apt-get and also install many other packages too like vim.

    • Run The following to download apt-cyg with wget. Note you can prompt to install gdb, vim or dos2unix if you want to use them or just remove them, you can install even more packages of your choice if you wish !

      wget rawgit.com/transcode-open/apt-cyg/master/apt-cyg
install apt-cyg /bin
apt-cyg install zsh git gdb dos2unix openssh chere vim
  • If you want your home folder to be your user's folder, you need to edit cygwin64/etc/nsswitch.conf. You can do this in the text editor you just downloaded, or type explorer /etc to open the root directory to edit the file. Add this line to the bottom: db_home: windows
    • Setting Up oh-my-zsh
  • Install oh-my-zsh from it's website or github.
  • Add plugins - I use 3 plugins for my dev environment:
    • So my ~/.zshrc file looks like plugins=(git zsh-yarn-completions zsh-autosuggestions)
    I also add alias for open to the windows explorer
    alias open=explorer.exe
    Integrate with terminals
    Windows terminal
    Edit your settings.json with the following profile:
    "defaultProfile": "{61c54bbd-c2c6-5271-96e7-009a87ff44ba}",
    "profiles": 
    {
        "defaults": {},
        "list": 
        [
            {
                "background": "#282C34",
                "commandline": "C:/cygwin64/bin/bash.exe /bin/xhere /bin/zsh",
                "cursorColor": "#FFFFFF",
                "foreground": "#DCDFE4",
                "guid": "{61c54bbd-c2c6-5271-96e7-009a87ff44ba}",
                "hidden": false,
                "name": "Work",
                "startingDirectory": "C://devl//work"
            },
      ]
  }
    VSCode
    In settings.json add the following settings:
    "terminal.integrated.shell.windows": "C:\\Cygwin64\\bin\\bash.exe",
  "terminal.integrated.shellArgs.windows": ["/bin/xhere", "/bin/zsh"],
    Webstorm
    Add C:/cygwin64/bin/bash.exe /bin/xhere /bin/zsh to Shell path setting
    image
    Conclusion
    I highly recommend using oh-my-zsh in your dev environment for better auto-completions in your terminal. Because of file watching issue with WSL2, I use Cygwin to help with the zsh installation.
    If you know some improvements to this setup - feel free to comment about.
