This video tutorial of Joseph IT shows the way to install emmet plugin or extension in Visual studio code or vscode simply!If you are a visual studio code us. Read on to learn about the Emmet 2.0 changes in Visual Studio Code. New modular approach to Emmet. Previously, the Emmet library was a single monolithic codebase that was used for every Emmet action. The author of Emmet, Sergey Chikuyonok, envisioned a new world for Emmet 2.0 with smaller, re-usable modules. The 'Emmet & HTML' Lesson is part of the full, Visual Studio Code course featured in this preview video. Here's what you'd learn in this lesson: Mike introduces Emmet, a text editor plugin for an abbreviation syntax that generates snippet auto-completions optimizing workflows for HTML, CSS, and JSX. Mike reviews Emmet's HTML abbreviations syntax.
Visual Studio Code supports most of the Emmet Actions including expanding Emmet abbreviations and snippets.
In the July 2017 (v1.15) release of VS Code, we introduced Emmet 2.0, which enabled features like Emmet in the suggestions/auto-completion list, and multi-cursor support. Read more on the why's and how's of this major overhaul in the Emmet 2.0 blog post.
Emmet abbreviation and snippet expansions are enabled by default in html
, haml
, jade
, slim
, jsx
, xml
, xsl
, css
, scss
, sass
, less
and stylus
files. As well as any language that inherits from any of the above like handlebars
and php
.
When you start typing an Emmet abbreviation, you will see the abbreviation displayed in the suggestion list. If you have the suggestion documentation fly-out open, you will see a preview of the expansion as you type. If you are in a stylesheet file, the expanded abbreviation shows up in the suggestion list sorted among the other CSS suggestions.
If you have disabled the editor.quickSuggestions
setting, you won't see suggestions as you type. You can still trigger suggestions manually by pressing kb(editor.action.triggerSuggest)
and see the preview.
If you don't want to see Emmet abbreviations in suggestions at all, then set emmet.showExpandedAbbreviation
to never
and use the command Emmet: Expand Abbreviation to expand your abbreviations. You can also bind any keyboard shortcut to the command id editor.emmet.action.expandAbbreviation
as well.
If you want to use the kbstyle(Tab)
key for expanding the Emmet abbreviations, add the setting emmet.triggerExpansionOnTab
and set it to true
. This setting allows using the kbstyle(Tab)
key for indentation when text is not an Emmet abbreviation.
Emmet suggestions may not always show up at the top of the suggestion list. This can be either because you have set editor.snippetSuggestions
to top
or if you are on a stylesheet file, it is sorted among other CSS suggestions. To ensure Emmet suggestions are always on top, you can set emmet.showSuggestionsAsSnippets
to true
and editor.snippetSuggestions
to top
.
To enable the Emmet abbreviation expansion in file types where it is not available by default, use the emmet.includeLanguages
setting. Make sure to use language ids for both sides of the mapping.
For example:
Emmet has no knowledge of these new languages, and so you might feel Emmet suggestions showing up in non html/css context. To avoid this you can set emmet.showExpandedAbbreviation
to inMarkupAndStylesheetFilesOnly
.
Note: If you used emmet.syntaxProfiles
previously to map new file types, from VS Code 1.15 onwards you should use the setting emmet.includeLanguages
instead. emmet.syntaxProfiles
is meant for customizing the final output only.
Custom Emmet snippets need to be defined in a json file named snippets.json
. The emmet.extensionsPath
setting should have the path to the directory containing this file.
Below is an example for the contents of this snippets.json
file.
Authoring of Custom Snippets in Emmet 2.0 via the snippets.json
file differs from the old way of doing the same in a few ways:
Topic | Old Emmet | Emmet 2.0 |
---|---|---|
Snippets vs Abbreviations | Supports both in 2 separate properties called snippets and abbreviations | The 2 have been combined into a single property called snippets. See default html snippets and css snippets |
CSS snippet names | Can contain : | Do not use : when defining snippet names. It is used to separate property name and value when Emmet tries to fuzzy match the given abbreviation to one of the snippets. |
CSS snippet values | Can end with ; | Do not add ; at end of snippet value. Emmet will add the trailing ; based on the file type (css/less/scss vs sass/stylus) or the emmet preference set for css.propertyEnd , sass.propertyEnd , stylus.propertyEnd |
Cursor location | ${cursor} or | can be used | Use only textmate syntax like ${1} for tab stops and cursor locations |
HTML custom snippets are applicable to all other markup flavors like haml
or jade
. When snippet value is an abbreviation and not actual HTML, the appropriate transformations can be applied to get the right output as per the language type.
For example, for an unordered list with a list item, if your snippet value is ul>li
, you can use the same snippet in html
, haml
, jade
or slim
, but if your snippet value is <ul><li></li></ul>
, then it will work only in html
files.
If you want a snippet for plain text, then surround the text with the {}
.
Values for CSS Emmet snippets should be a complete property name and value pair.
CSS custom snippets are applicable to all other stylesheet flavors like scss
, less
or sass
. Therefore, don't include a trailing ;
at the end of the snippet value. Emmet will add it as needed based on the whether the language requires it.
Do not use :
in the snippet name. :
is used to separate property name and value when Emmet tries to fuzzy match the abbreviation to one of the snippets.
Note: After making changes to the snippets.json
file, remember to reload VS Code for it to take effect.
The syntax for tab stops in custom Emmet snippets follows the Textmate snippets syntax.
${1}
, ${2}
for tab stops and ${1:placeholder}
for tab stops with placeholders.|
or ${cursor}
was used to denote the cursor location in the custom Emmet snippet. This is no longer supported. Use ${1}
instead.Below are Emmet settings that you can use to customize your Emmet experience in VS Code.
emmet.includeLanguages
Use this setting to add mapping between the language of your choice and one of the Emmet supported languages to enable Emmet in the former using the syntax of the latter.Make sure to use language ids for both sides of the mapping.
For example:json'emmet.includeLanguages': { 'javascript': 'javascriptreact', 'vue-html': 'html', 'plaintext': 'jade'}
emmet.excludeLanguages
If there is a language where you do not want to see Emmet expansions, add it in this setting which takes an array of language id strings.
emmet.syntaxProfiles
See Emmet Customization of output profile to learn how you can customize the output of your HTML abbreviations.
For example:json'emmet.syntaxProfiles': { 'html': { 'attr_quotes': 'single' }, 'jsx': { 'self_closing_tag': true }}
emmet.variables
Customize variables used by Emmet snippets.
For example:json'emmet.variables': { 'lang': 'de', 'charset': 'UTF-16'}
emmet.showExpandedAbbreviation
Controls the Emmet suggestions that show up in the suggestion/completion list.
Setting Value | Description |
---|---|
never | Never show Emmet abbreviations in the suggestion list for any language. |
inMarkupAndStylesheetFilesOnly | Show Emmet suggestions only for languages that are purely markup and stylesheet based ('html', 'pug', 'slim', 'haml', 'xml', 'xsl', 'css', 'scss', 'sass', 'less', 'stylus'). |
always | Show Emmet suggestions in all Emmet supported modes as well as the languages that have a mapping in the emmet.includeLanguages setting. |
Note: In the always
mode, the new Emmet implementation is not context aware. For example, if you are editing a JavaScript React file, you will get Emmet suggestions not only when writing markup but also while writing JavaScript.
emmet.showAbbreviationSuggestions
Shows possible emmet abbreviations as suggestions. Its true
by default.
For example, when you type li
, you get suggestions for all emmet snippets starting with li
like link
, link:css
, link:favicon
etc.This is helpful in learning Emmet snippets that you never knew existed unless you knew the Emmet cheatsheet by heart.
Not applicable in stylesheets or when emmet.showExpandedAbbreviation
is set to never
.
emmet.extensionsPath
Provide the location of the directory that houses the snippets.json
file which in turn has your custom snippets.
emmet.triggerExpansionOnTab
Set this to true to enable expanding Emmet abbreviations with kbstyle(Tab)
key. We use this setting to provide the appropriate fallback to provide indentation when there is no abbreviation to expand.
emmet.showSuggestionsAsSnippets
If set to true
, then Emmet suggestions will be grouped along with other snippets allowing you to order them as per editor.snippetSuggestions
setting. Set this to true
and editor.snippetSuggestions
to top
, to ensure that Emmet suggestions always show up on top among other suggestions.
emmet.preferences
You can use this setting to customize Emmet as documented in Emmet Preferences. The below customizations are currently supported:- css.propertyEnd
- css.valueSeparator
- sass.propertyEnd
- sass.valueSeparator
- stylus.propertyEnd
- stylus.valueSeparator
- css.unitAliases
- css.intUnit
- css.floatUnit
If you want support for any of the other preferences as documented in Emmet Preferences, please log a feature request for the same.
Below are some of the upstream issues with Emmet 2.0 that we are working on fixing. Any help in these areas is appreciated.
@-
to get numbering in descending order in repeaters is not supported. Issue: emmetio/html-transform#2+
like select+
and ul+
from the Emmet cheatsheet are not supported. Issue: emmetio/html-matcher#1August 7, 2017 Ramya Rao, @ramyanexus
In the July 2017 release of Visual Studio Code (version 1.15), we're shipping a better Emmet experience which has been in preview for the past 2 releases.
Its features include:
As part of this update, we have re-written all of the Emmet actions using new npm modules from @emmetio.
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.
Note: To continue to expand Emmet abbreviations and snippets using the Tab key, set emmet.triggerExpansionOnTab
to true
.
Read on to learn about the Emmet 2.0 changes in Visual Studio Code.
Previously, the Emmet library was a single monolithic codebase that was used for every Emmet action. The author of Emmet, Sergey Chikuyonok, envisioned a new world for Emmet 2.0 with smaller, re-usable modules.
There are now separate npm modules from @emmetio for the different parts of the pipeline required to expand an Emmet abbreviation. These include steps such as:
There are also separate modules for parsing HTML and CSS documents to aid in implementing the rest of the Emmet features. You can find these modules on npm under emmetio.
This modular approach was taken to allow editor plugins to use the editor specific APIs for better Emmet integration with the editor features. For example, this approach has allowed us to:
There were two issues with using the Tab key as a keyboard shortcut for Emmet expansion:
Sergey Chikuyonok realized that having Emmet in the suggestion list would be a more pleasant experience. That it helped us solve the above two issues, was an added bonus.
With Emmet abbreviations now easily accessible via suggestion list, we were able to remove the default association of Tab key with the Emmet: ExpandAbbreviation command. The Tab key is now free to do what it was meant to do: indent.
If you have the editor.quickSuggestions
setting turned off, you will have to press ⌃Space (Windows, Linux Ctrl+Space) to trigger the suggestion/auto-completion list manually.
If you don't want Emmet showing up in the suggestion/auto-completion list, set emmet.showExpandedAbbreviation
to never
.
You can still bind any keyboard shortcut (other than Tab key) to the editor.emmet.action.expandAbbreviation
command or use Emmet: Expand Abbreviation from the Command Palette.
If you prefer the Tab key for expanding your abbreviations, then add the setting emmet.triggerExpansionOnTab
to your settings and set it to true
. We use this setting to provide the appropriate fallback to provide indentation when there is no abbreviation to expand.
There are a few other changes that we have documented in the new Emmet page:
emmet.includeLanguages
instead of emmet.syntaxProfiles
setting to enable Emmet in other file typesI want to thank Sergey Chikuyonok for his amazing work on modularizing Emmet and helping us bring these improvements to VS Code.
Thanks also goes to everyone who used the new Emmet in VS Code when it was in preview and provided great feedback through GitHub issues. The discussions in GitHub issues were very helpful in getting to the current user experience.
Special thanks to Steve Lombardi, Jens Hausdorf, Vladimir Sizikov, Niichie, Thomas Klepzig and many more who used the VS Code Insiders builds to test my bug fixes and feature additions.
Do you miss any features of the old Emmet? Having trouble using the new Emmet? Feel free to create an GitHub issue and we will do our best to help you out.
It is also easier than ever to contribute to Emmet in VS Code as it is now an extension. The emmet folder in the VS Code GitHub repo has all the source code you need to get started.
Happy Coding!
