Since Emmet works in so many IDEs and applications, it's worth looking at how we can incorporate it into some of the most popular editors. In this video, learn how to install Emmet into Brackets, Atom, Visual Studio, and Coda editors.
Databases for mac os. 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.
How to expand Emmet abbreviations and snippets
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.
Emmet when quickSuggestions are disabled
If you have disabled the editor.quickSuggestionssetting, you won't see suggestions as you type. You can still trigger suggestions manually by pressing kb(editor.action.triggerSuggest) and see the preview.
Disable Emmet in suggestions
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.
Using Tab for Emmet expansions
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 suggestion ordering
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.
Emmet abbreviations in other file types
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.
Using custom Emmet snippets
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 Emmet snippets
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 {}.
CSS Emmet snippets
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.
Tab stops and cursors in custom snippets
The syntax for tab stops in custom Emmet snippets follows the Textmate snippets syntax.
- Use
${1},${2}for tab stops and${1:placeholder}for tab stops with placeholders. - Previously,
|or${cursor}was used to denote the cursor location in the custom Emmet snippet. This is no longer supported. Use${1}instead.
Emmet configuration
Below are Emmet settings that you can use to customize your Emmet experience in VS Code.
emmet.includeLanguagesUse 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.excludeLanguagesIf 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.syntaxProfilesSee 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.variablesCustomize variables used by Emmet snippets.
For example:
json'emmet.variables': { 'lang': 'de', 'charset': 'UTF-16'}emmet.showExpandedAbbreviationControls the Emmet suggestions that show up in the suggestion/completion list.
Setting Value Description neverNever show Emmet abbreviations in the suggestion list for any language. inMarkupAndStylesheetFilesOnlyShow Emmet suggestions only for languages that are purely markup and stylesheet based ('html', 'pug', 'slim', 'haml', 'xml', 'xsl', 'css', 'scss', 'sass', 'less', 'stylus'). alwaysShow Emmet suggestions in all Emmet supported modes as well as the languages that have a mapping in the emmet.includeLanguagessetting.Note: In the
alwaysmode, 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.showAbbreviationSuggestionsShows possible emmet abbreviations as suggestions. Its
trueby default.For example, when you type
li, you get suggestions for all emmet snippets starting withlilikelink,link:css,link:faviconetc.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.showExpandedAbbreviationis set tonever.emmet.extensionsPath
Provide the location of the directory that houses the snippets.json file which in turn has your custom snippets.
emmet.triggerExpansionOnTabSet 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.showSuggestionsAsSnippetsIf set to
true, then Emmet suggestions will be grouped along with other snippets allowing you to order them as pereditor.snippetSuggestionssetting. Set this totrueandeditor.snippetSuggestionstotop, to ensure that Emmet suggestions always show up on top among other suggestions.emmet.preferencesYou 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.floatUnitIf you want support for any of the other preferences as documented in Emmet Preferences, please log a feature request for the same.
Known issues in Emmet 2.0
Below are some of the upstream issues with Emmet 2.0 that we are working on fixing. Any help in these areas is appreciated.
- Use of
@-to get numbering in descending order in repeaters is not supported. Issue: emmetio/html-transform#2 - HTML snippets ending with
+likeselect+andul+from the Emmet cheatsheet are not supported. Issue: emmetio/html-matcher#1
In Visual Studio Code, we can use Emmet to speed up our development. Let’s look at how to do this.
In VS Code, create a new file called test.html:
Enter doc and note the Emmit Abbreviation appears:
Clicking on the information icon we can see what the snippet will look like:
Press tab to get the HTML inserted into the document:
Also, if we were to type ! instead, we would get the same result:
From here, we can use several Emmet shortcuts. For example, to enter an a href, instead of typing the full text, we can type a and then tab:
On tabbing, we get the a href code ready to use:
