Emmet in VS Code

VS Code is a code editor redefined and optimized for building and debugging modern web and cloud applications.

VS Code is one of my favorite code editor. I love the various features like embedded Git Control, Code completion, snippets, code refactoring etc.

I’m a full stack web developer (I used to call myself with that name), I have been using the vs code from its earlier release. I use to follow the release notes of VS Code on every release.

I always used to share the details of VS Code new features with friends, colleagues and all. Some of the features I have excited about was integrated terminal, Side by Side editing, Command palette, Markdown preview and list goes on.

Today, in this post I would like to share one of the interesting feature of VS Code which is involved with Code completion.

It’s Emmet!

So the next big question is,

What is Emmet?

Wiki says,

Emmet is a set of plug-ins for text editors that allow for high-speed coding and editing in HTML, XML, XSL, and other structured code formats via content assist.

Me:

To be short, it helps to code completion, add snippets, etc.

And next big question is, even some text editor also doing this fair job nowadays. Why Emmet?

Yes, nowadays all the editors comes up with code completion or syntax suggestion intellisense.

However, Emmet got some cool features like syntax abbreviation, improves HTML, CSS workflow. Using Emmet we can quickly write a bunch of code, wrap code wit new tags.

Your favorite may be Atom, Sublime, Brackets or something else. Emmet supports most of your favorite editors.

Check this link on how to integrate Emmet with your editor.

It’s a plugin, you can install or integrate with your code editors.

 

Emmet in VS Code

The one good news is that we don’t have to download & install the Emmet in VS Code.

Emmet is built in with VS Code, no extension in required. OK, that’s the base story; now let’s start with how to use the features.

 

How to expand Emmet abbreviations?

Emmet abbreviation and snippets are enabled by default for html, haml, jade, slim, jsx, xml, xsl, css, scss, sass, less and stylus files.

Mostly, Tab key is used to complete the code abbreviation. We have to type the syntax and click tab key to expand the abbreviations.

We expand the single html tag or even expand the hierarchy of html tag at the same time by clicking tab key.

An important change is that the Tab key is no longer the default way to expand Emmet abbreviations. Instead, Emmet abbreviations will now appear in the suggestion list. They can be selected like any other smart completion and on selection, the abbreviation will be expanded.

We can quickly view the Emmet abbreviation by clicking the info icon next to list shown. By typing text next to hash (#) will be taken as id and text next to period(.) will be considered as class name. Emmet basically works related to CSS selectors.

And also we can create multiple list of same syntax with unique id as well.

We can generate lorem ipsum text with default number of words or certain number of text by mentioning the word count.

Steps to set customized external terminal in VS Code

Step 1:
Go to File -> Preferences -> User settings

Step 2:
Add one of the following line based on the environment to settings.json file

// to run on OS X
"terminal.external.osxExec": "Terminal.app"

Restart the VS Code instance to apply the settings.
