There’s a decent chance that you, like me, ended up with Visual Studio Code incorrectly configured as Git’s core editor. I’m talking about Windows here.
Take a look at your .gitconfig file and see what you have configured. You will likely find that in c:\users\<username>.
Under the [core] section, look for the editor key. What do you have for a value?
If your Visual Studio Code path ends with code.cmd, then it’s not correct. It should end with code.exe. And it should have a -w flag. The -w flag tells the launching context to block until the process is terminated. That means that if you run a Git command from the command line that launches Code as a text editor, the command line should be blocked until you’re done editing that file and shut down Code.
Let’s say, for instance, that you have committed some files and then realize that you forgot one. You could commit it as a new commit, but it makes more sense to tack the change on to the last commit (assuming you haven’t pushed your commit up to a shared repo yet!).
To do this, you simply run
git commit --amend at the command line. This amends your staged files to the last commit. It also launches your default text editor so you can determine if you want to keep the same commit message you elected previously or overwrite it.
This should open your text editor, wait for you to make and save your changes and then shut down your editor before releasing control of the command line and continuing on.
You can simply edit your .gitconfig file to add this configuration, but it’s easier to run this…
git config --global core.editor "'C:\Program Files (x86)\Microsoft VS Code\code.exe' -w"
…from your command line.
The bells ring, the confetti flies, the fans go wild!
The two things we all wanted from Code was…
- to see it go open source
- to get extensions.
If you were following the user voice page for Code like I was, you’d have seen way more votes for extensions than for any other feature. The size of the vote count made it look like not having extensions was a total deal breaker and for many folks I talked to… it was.
Well, now it’s here!
It’s here in full force. Not only are extensions available, but there are already a whole lotta cool extensions available in the online gallery. There were about 60 a couple days before launch - a metric that jumped over 20 points by the time Sean McBreen was showing off (here and here) the announcement at the Connect() conference. And there are obviously a lot more now just a few weeks later.
Getting extensions is like getting three wishes from a genie in a bottle and for your first wish requesting unlimited wishes. Code is a great tool, but with extensions, you can make it do most anything you want.
Some of the great things about Code extensions are…
they’re easy to write. To run and test an extensions, Code launches an instance of itself. It’s a bit like Inception that way. Then you can just play with your extension as it currently is and be sure it’s behaving as you designed.
they run in a different process. When you start up Code, it’s okay if you have 38,329,420 installed, because they’re not loading synchronously in the same process as your main editor. Granted 38M+ extensions is going to bog something down and I think you’ll have a hard time finding that many unique extensions in the marketplace any time soon, but my point is that you don’t have to worry about the performance impact of installing your favorite few.
publishing them is just about the easiest thing in the whole world. It’s literally one command - nay, one short command…
I haven’t found the time to install every extension (who has that kind of time?!), but here are three of my favorites so far…
Markdown (.md) files are really handy. If you’re not familiar with markdown files, just think of them as a cross between text files and HTML files. Text files are nice because they are very readable. Markdown files are readable still but they give us the ability to easily bring in rich content like hyperlinks, images, and formatting. One of the great additions to markdown is the ability to indicate spans or blocks of code and even in some cases to specify the code language and get great formatting.
So it’s no surprise that markdown files have become the standard for creating documentation and meta text for code repositories. Developers work with markdown a lot and it’s exciting to have a bit of help.
The MDTools extension allows you to do a lot of those little things to a selected block of text. You can convert to upper case, lower case, or title case, you can HTML encode or decode, and you can even convert to ASCII art - an extremely fun use case! To activate these tools, install the extension, restart the editor, select some text, and then use the ALT + T keyboard shortcut.
There’s a lot more the MDTools extension can do to, so check it out.
Quick Snippet is a great idea for an extension by my colleague Sara Itani (@mousetraps). See my interview of Sara on episode 048 of my podcast CodeChat. It allows a developer to highlight a block of text they’ve written and quickly and easily create a snippet out of it. In my experience, it takes a little bit of discipline to create snippets today to save time tomorrow. This extension excites me because it removes some of the friction and makes snippet creation fast. Now I can save time on saving time!
This one’s just cute and fun and shows off the power and versatility of extensions in Code. The Twitter extension let’s you read and even write
Now here’s the real winning tip. You don’t have to just check every week to see if someone has created your new doodad yet. You can just build it yourself!
If you’re wondering if it’s hard, it’s not. If I can make an extension, you can.
Watch this. I’m going to build the hello world extension from start to finish in just over a minute. Granted I sped it up a little and skimmed over the long running npm install bits, but still. You can see that it’s an easy process. Note: this assumes you have Node.js and Visual Studio Code installed already.
If that went just a little bit too fast for you, you can get the complete tutorial by going to code.visualstudio.com/docs/extensions/example-hello-world, and for a bunch more information about getting started creating Code extensions, go to code.visualstudio.com/docs/extensions/overview.
My team has put together a bunch of different videos and blog posts to sum up the announcements from Connect(). You can see the rest of them by visiting Jerry Nixon‘s post Inside the Code: What’s New with Visual Studio.
Visual Studio Code is now open source.
Me: What do you think of Visual Studio Code?
Some Dude: It’s awesome. I just wish it were open source.
Me: You need to fork it? Tweak it?
Some Dude: No.
I get it. I like open source stuff too.
Realistically, there are few products I have time to fork and fewer still that I have need to fork.
But even when I have no need to fork a project and no intention to submit a pull request any time soon, still I want it to be open source. Why? Because… freedom.
I like closed source products too, actually. Closed source products can be sold. Selling products earns a company money. Companies with money can create big research and development departments that can tinker with stuff and make new, cool stuff. And ultimately, I like new cool stuff.
The best scenario for me, a consumer, though, is when a big company with a big research and development department can afford to make something cool and free and open, because they make money on other products.
Some products (think Adobe Photoshop) are obviously a massive mess of proprietary code that feel right to belong to their parent company. They need the first-party control.
Others, like Code feel more like they belong to the community. That’s how I feel anyway.
And now I can. Visual Studio Code is officially OSS!
In case you missed it, Microsoft announced at Connect() 2015 that Code was graduating from preview to beta status and that it would be open sourced.
To see Code’s code comfortably settled into its new home, just head over to github.com/microsoft/vscode. From there, you can clone it, fork it, submit an issue, submit a PR… or look at what the team is working on and who else is involved. You know… you can do all of the GitHub stuff with it.
So there it is. It’s not only free as in “free beer” now, but also as in “free speech”.
The actual announcement is buried in the keynote, so the best way to get the skinny on this announcement, the details, and the implications is to watch the Visual Studio Code session hosted on Connect() Day 2 by @chrisrisner. The panel shows off Code in serious depth. It’s a must-see session if you’re into this stuff.
One of the more exciting things they showed off is actually the second gigantic announcement regarding Code… the addition of extensions to the product, but that’s a big topic for another day and another blog post.
What exactly does the open sourcing of Code mean for you? As I mentioned, you may or may not be interested in ever even viewing the source code for Code. The real gold in this announcement is the fact that Code now belongs to the community. It’s ours. It’s something that we’re all working on together. That’s no trivial matter. Microsoft may have kicked it off and may be a huge contributor to it here forward, but so are you and I.
So whether you’re going to modify the code base, study the code base, or just take advantage of the warm feeling that open source software gives us, you know now that the best light-weight code editor for Windows, Linux, and Mac, is ready for you.
Let’s have a quick look at the code for Code using Code. The official repo is at http://github.com/Microsoft/vscode. So start by cloning that into your local projects folder. My local projects folder is
c:\code, so I do this…
Then, you launch that project in Code using…
You’ve got it now. So I just added “codefoster” to a readme.md file to simulate a change and then hit CTRL + SHIFT + G to switch to the Git source control section of VS Code, and here’s what I see…
Notice that the changed file is listed on the left and when highlighted the lines that were changed are compared in split panes on the right. Checking this change in would simply involve typing the commit message (above the file list) and then hitting the checkmark.
This interface abstracts away some of the git concepts that tend to intimidate newcomers - things like pushing, pulling, and fetching - with a simpler concept of synchronizing which is accomplished via the circle arrow icon.
It’s important to note that I wouldn’t be able to check this change in here because I don’t have direct access to the VS Code repo. Neither do you most likely. The git workflow for submitting changes to a repo that you don’t have direct access to is called a pull request. I’ll leave the expansion of this topic to other articles online, but in short it’s done by forking the repo, cloning your fork, changing your files, committing and pushing to your fork, and then using github.com to submit a pull request. This is you saying to the original repo owner, “Hey, I made some changes that I think benefit this project. They are in my online repository which I forked from yours. I hereby request you _pull _these changes into the main repository.
It’s quite an easy process for the repo owner and I don’t think a repo owner on earth is opposed to people doing work for them by submitting PR’s. :)
Again, getting involved simply means interacting and collaborating on GitHub. Here’s how…
- Check out the list of issues (there are already over 200 of them as I type this) on microsoft/vscode repo.
- Chime in on the issues by submitting comments.
- Create your own issue. See how.
- Clone the code base using your favorite git tooling or using
git clone https://github.com/microsoft/vscode.giton your command line. That will allow you to
git pullanytime you need to get the latest. Having the code means you can browse it whenever you’re wondering how something works. See how.
- Fork the code using GitHub if you want to create a copy of the code base in your own GitHub repo. Then you can modify that code base and submit it via a pull request whenever you’re certain you’ve added some value to the project. See how.
And you can chatter about Code as well on Twitter using @Code. As to how they got such an awesome handle on Twitter I have no idea.
Also check out my mini-series I’m calling Tidbits of Code and Node on the Raw Tech blog on Channel 9 where I’ve been talking a lot about Code (and Node) and plan to do even more now that the dial for its awesome factor was turned up a couple of notches.
In fact, I recorded a Tidbits of Code and Node on this topic precisely where I show you how to find the source code on GitHub, how to clone it, how to fork it, and all that goodness. You can watch it below or find it anytime on Channel 9.
Happy coding in Code!
If you haven’t watched the first day’s keynote from Microsoft’s Build 2015 conference, go do that now. It has a few wow moments such as Android and iOS code for building Windows 10 apps, elastic pools for Azure SQL databases, and the amazing HoloLens robot that was a hologram and a real robot in one - amazing!
One of the pieces of the conference that’s going to affect my every day, though is Visual Studio’s new, free, light edition called simply Code. Code is what I’ve been looking for in a code editor - in a text editor even. It will replace a few other apps in my MRU list - Visual Studio Community, Notepad++, and Atom to name a few.
code.exe is in your path after your basic install, so from your shell, you can type
code to run the app from scratch. You can also type
code myfile.txt and launch into the editing of your file or
code mydirectory to open it with the explorer pane’s context already set to your directory. So my new favorite command is going to be
code . for opening the current directory in Code. I was looking for some PowerShell magic to make that possible with VS Community, but now I no longer have the need.
Speed. It takes about 3 seconds to launch code.exe cold, and iut doesn’t appear to take any extra milliseconds to load either a file or a directory.
Essentials. Code is just the essentials. It’s basically a new perspective on authoring code that hopefully complements Visual Studio. If I’m an enterprise developer with a massive code base and a lot of static analysis, workflow automation, and other tooling built in to my development environment, then I can see running the full editions of Visual Studio. There are a lot of support features, it’s plug-in capable, it has excellent GUI Azure tooling. But if I’m working on what I might call more of a scrappy project - a website, a Node.js app, a sample, or whatever - Code is all I need. For some people, I suspect Code will cover 10% of the use cases, but for me, it’s more like 90%. And actually, this is only the beginning. Check out what it says in the official docs: “In future previews, as we continue to evolve and refine this architecture, Visual Studio Code will include a public extensibility model that lets developers build and use plug-ins, and richly customize their edit-build-debug experience.”
CTRL + SHIFT + P to open the Command Palette and do most anything you want.
Autosave. Code can be configured to autosave your file as you change it like Atom does. Keep in mind, of course, that if you’re using file watchers like gulp’s .watch() method, this is going to trigger every time you type a character in your code. Autosave is off by default. To turn it on, hit
CTRL + SHIFT + P and type auto.
Search. You can
CTRL + SHIFT + F search over all files in the open folder and it supports regex. It ignores certain folders like node_modules by default since that’s the right thing to do.
There’s a ton more in Code, but that’s all I’m mentioning for now.
I hope you like your new home for code as much as I do so far.
After upgrading to Windows 10 Technical Preview Build 9926, I found myself unable to run the Windows Phone Emulator either from the Developer Power Tools or by executing a phone app from Visual Studio 2013.
I found a forum post online that showed how to resolve it. Here it is.
Open the Hyper-V Manager
Now click on Virtual Switch Manager on the right under Actions…
And then choose the Windows Phone Emulator Internal Switch from the list of switches and hit Remove. Don’t worry, a new one will be automatically created for you the next time you try to connect to the emulator in Visual Studio.
Now launch Visual Studio as an administrator…
And try again to execute a Windows Phone project. The emulator took quite a while for me to open up, but it eventually did and worked great.
Hope this helps someone.
