“… However, when we talked with web developers, they still struggled with using Windows as their primary devbox.”
The above quote is from Kevin Gallo, the VP of Windows Dev platform, and was delivered around mark 0:38 of his presentation in Microsoft’s Build 2016 keynote. He then continued with the observation that “… many of them have workflows which rely on open source command line tools, scripts and frameworks”, and finished with a slide that his audience was – at first – slightly unsure on how excited to get about: Bash is coming to Windows.
If you let the video play for another 7 seconds, you’ll also catch a glimpse of Gallo’s audience. You can see the emotions depicted on their faces form a picture that explains perfectly the complex (and sometimes tumultuous) relationship of Microsoft with Linux and the Open Source world. Three persons are smiling excitedly and beginning to slow clap (the ones that suddenly realise how much easier managing their OS stack or scripting their Windows environment will become). You then have the classic cautious indifference of the majority of developers that wait to see whether this is “worth getting excited about”. Finally, you can also detect some unguarded annoyance from the fanboy crowd (“Seriously? I have to sit and hear about Bash? What’s wrong with PowerShell?”).
Personally, I belong to the first group. Despite working with open source technologies since the beginning of my professional career back in 2003, I’ve never managed to move away from Windows. To this effect, when I saw Rich Turner and Russ Alexander casually doing a apt-get install git on Windows to install git, I was excited. A lot.
But until the functionality showcased in the video above is mature and stable enough to be rolled out, I’ll continue using my current workflow which has served me faithfully since 2011: And that is bash on Windows (To be precise: A more “cut down” version of Bash. Read on for details).
One might argue that Windows was never meant to be “driven” from the command line.
Microsoft tried to mitigate this back in 2006 by rolling out PowerShell, a shell and scripting language that gives users full access to their whole Windows environment. For Windows devs this was a great extra tool but for all other developers it was still not enough to lure them away from the power and versatility they found on the Linux command line.
Add to this the strongly opinionated naming conventions and approaches that PowerShell inherited from the .NET Framework (did you know that cd is but an alias to the “proper” command which is Get-ChildItem? That’s camelcase _and_ a dash that autocompletes with tab even if you type it in lowercase. Strange stuff) and you can see why it’s really hard for e.g. a PHP developer to consider it for his dev workflow.
When every single blogpost or article or tutorial written about a subject, e.g. “how to rebase branches in git”, includes instructions and screenshots that clearly demonstrate the flow in a Linux shell, it’s only natural for the developer to assume that this is the correct way of doing things.
For my frontend-with-a-bit-of-PHP-but-from-a-Windows-OS workflow I always relied on certain “battle proven” tools. WinSCP was the weapon of choice when files needed to be moved from one place to another (either via FTP, SFTP, SCP or even rSync). Putty allowed me to connect via SSH to all my dev boxes. TortoiseGIt ensured that I could use git directly from my Windows explorer interface.
The first “lightbulb / aha” moment for me occurred when I installed Git for Windows after being prompted to “try it out on the command line” by a colleague.
One of the steps of the install wizard prompts you to choose “How would you like to use Git from the command line?”:
… and it mentioned “Bash”!
Installation completes and suddenly I get a shell in Windows that looks suspiciously similar to what I’m used to in Linux or iOS installations:
Kudos? To the awesome devs that worked to bring Git to windows – https://git-for-windows.github.io/.
In essence the installer sets up a unix-like shell environment (MinGW – “Minimalist GNU for Windows”) which – very roughly speaking – creates the needed Unix layer that shells like Bash can run onto.
A terminal emulator called MinTTY is also installed (shown in screenshot #3 above) which is a Windows program that runs the Bash shell which in turn enables you to use quite a good subset of the Linux commands needed for an open source dev workflow.
… especially if you are an ex-designer-turned-frontend-developer. Going from the black and white severity of cmd.exe (where you could not even resize the window to the dimensions you wanted) to MinTTY definitely boosted my “developer happiness” feeling:
In the above example, I manually mapped the colours from the famous Solarized colour theme to the default 16 ANSI colours. For the font I chose the crystal clear Consolas font set at 12 point, although I’ve recently been experimenting with Adobe’s Source Code Pro as an alternative.
The MinTTY window can be resized to any dimension of your choosing. You can also use the same shortcuts as you use in the browser to resize the text on the fly (CTRL+plus, CTRL+minus or CTRL+mouse wheel). Finally you can launch as many instances of MinTTY as you want, enabling you to lay out a series of windows into your codebase and file structure, exactly as it suits you:
The list below demonstrates just a small subset of the stuff you can do with Bash in Windows that I found particularly useful and / or helpful.
Indeed. But even if I do so, there is still a vast number of devs out there who still need / have to work with Windows. One year ago, Isaac Schlueter (co-founder and CEO of the Node Package Manager – NPM) had this to say:
The soon-to-be-released Windows Subsystem for Linux is a brilliant (and much-needed) step forward in making the Windows environment a first-class citizen for open source development workflows.Nevertheless, there is no need to wait for Microsoft to make WSL available to everyone.
I’ve been using Bash in Windows – in my daily workflow – for the last 5 years and it’s working like a charm.
If you want to do the same, simply install Git for Windows.
