# Emmet for Sublime Text [](http://codersclan.net/support/step1.php?repo_id=4) Official [Emmet](http://emmet.io) plugin (previously called _Zen Coding_) for Sublime Text. * [How to install](#how-to-install) * [Available actions](#available-actions) * [Extensions support](#extensions-support) * [Overriding keyboard shortcuts](#overriding-keyboard-shortcuts) * [Tab key handler](#tab-key-handler) ## How to install *Warning:* this plugin may not work at all in some OSes since it written in JavaScript and uses [PyV8](http://code.google.com/p/pyv8/) and [Google V8](https://developers.google.com/v8/) binaries to run. If you experience problems or editor crashes please [fill an issue](https://github.com/sergeche/emmet-sublime/issues). With [Package Control](http://wbond.net/sublime_packages/package_control): 1. Run “Package Control: Install Package” command, find and install `Emmet` plugin. 2. Restart ST editor (if required) Manually: 1. Clone or [download](https://github.com/sergeche/emmet-sublime/archive/master.zip) git repo into your packages folder (in ST, find Browse Packages... menu item to open this folder) 2. Restart ST editor (if required) -------------- **WARNING**: When plugin is installed, it will automatically download required PyV8 binary so you have to wait a bit (see _Loading PyV8 binary_ message on status bar). If you experience issues with automatic PyV8 loader, try to [install it manually](https://github.com/emmetio/pyv8-binaries). ## Available actions ## * [Expand Abbreviation](http://docs.emmet.io/actions/expand-abbreviation/) – <kbd>Tab</kbd> or <kbd>Ctrl+E</kbd> * Interactive “Expand Abbreviation” — <kbd>Ctrl+Alt+Enter</kbd> * [Match Tag Pair Outward](http://docs.emmet.io/actions/match-pair/) – <kbd>⌃D</kbd> (Mac) / <kbd>Ctrl+,</kbd> (PC) * [Match Tag Pair Inward](http://docs.emmet.io/actions/match-pair/) – <kbd>⌃J</kbd> / <kbd>Shift+Ctrl+0</kbd> * [Go to Matching Pair](http://docs.emmet.io/actions/go-to-pair/) – <kbd>⇧⌃T</kbd> / <kbd>Ctrl+Alt+J</kbd> * [Wrap With Abbreviation](http://docs.emmet.io/actions/wrap-with-abbreviation/) — <kbd>⌃W</kbd> / <kbd>Shift+Ctrl+G</kbd> * [Go to Edit Point](http://docs.emmet.io/actions/go-to-edit-point/) — <kbd>Ctrl+Alt+→</kbd> or <kbd>Ctrl+Alt+←</kbd> * [Select Item](http://docs.emmet.io/actions/select-item/) – <kbd>⇧⌘.</kbd> or <kbd>⇧⌘,</kbd> / <kbd>Shift+Ctrl+.</kbd> or <kbd>Shift+Ctrl+,</kbd> * [Toggle Comment](http://docs.emmet.io/actions/toggle-comment/) — <kbd>⇧⌥/</kbd> / <kbd>Shift+Ctrl+/</kbd> * [Split/Join Tag](http://docs.emmet.io/actions/split-join-tag/) — <kbd>⇧⌘'</kbd> / <kbd>Shift+Ctrl+`</kbd> * [Remove Tag](http://docs.emmet.io/actions/remove-tag/) – <kbd>⌘'</kbd> / <kbd>Shift+Ctrl+;</kbd> * [Update Image Size](http://docs.emmet.io/actions/update-image-size/) — <kbd>⇧⌃I</kbd> / <kbd>Ctrl+U</kbd> * [Evaluate Math Expression](http://docs.emmet.io/actions/evaluate-math/) — <kbd>⇧⌘Y</kbd> / <kbd>Shift+Ctrl+Y</kbd> * [Reflect CSS Value](http://docs.emmet.io/actions/reflect-css-value/) – <kbd>⇧⌘R</kbd> / <kbd>Shift+Ctrl+R</kbd> * [Encode/Decode Image to data:URL](http://docs.emmet.io/actions/base64/) – <kbd>⇧⌃D</kbd> / <kbd>Ctrl+'</kbd> * Rename Tag – <kbd>⇧⌘K</kbd> / <kbd>Shift+Ctrl+'</kbd> [Increment/Decrement Number](http://docs.emmet.io/actions/inc-dec-number/) actions: * Increment by 1: <kbd>Ctrl+↑</kbd> * Decrement by 1: <kbd>Ctrl+↓</kbd> * Increment by 0.1: <kbd>Alt+↑</kbd> * Decrement by 0.1: <kbd>Alt+↓</kbd> * Increment by 10: <kbd>⌥⌘↑</kbd> / <kbd>Shift+Alt+↑</kbd> * Decrement by 10: <kbd>⌥⌘↓</kbd> / <kbd>Shift+Alt+↓</kbd> ## Extensions support ## You can easily [extend](http://docs.emmet.io/customization/) Emmet with new actions and filters or customize existing ones. In `Emmet.sublime-settings`, define `extensions_path` setting and Emmet will load all `.js` and `.json` files in specified folder at startup. The default value of `extensions_path` is `~/emmet`, which points to _emmet_ folder inside your OS user’s home folder. Also, you can create sections named as extension files (e.g. `snippets`, `preferences` and `syntaxProfiles`) inside user’s `Emmet.sublime-settings` file and write your customizations there. See [original settings file](https://github.com/sergeche/emmet-sublime/blob/master/Emmet.sublime-settings#L61) for examples. ## Overriding keyboard shortcuts ## Sublime Text is a great text editor with lots of features and actions. Most of these actions are bound to keyboard shortcuts so it’s nearly impossible to provide convenient plugin shortcuts for third-party plugins. If you’re unhappy with default keymap, you can disable individual keyboard shortcuts with `disabled_keymap_actions` preference of `Emmet.sublime-settings` file. Use a comma-separated list of action names which default keyboard shortcuts should be disabled. For example, if you want to release <kbd>Ctrl+E</kbd> (“Expand Abbreviation”) and <kbd>Ctrl+U</kbd> (“Update Image Size”) shortcuts, your must set the following value: "disabled_keymap_actions": "expand_abbreviation, update_image_size" You should refer `Default (Your-OS-Name).sublime-keymap` file to get action ids (look for `args/action` key). To disable all default shortcuts, set value to `all`: "disabled_keymap_actions": "all" Not that if you disabled any action like so and you’re create your own keyboard shortcut, you **should not** use `emmet_action_enabled.ACTION_NAME` context since this is the key that disables action. ### Tab key handler ### Emmet plugin allows you to expand abbreviations with <kbd>Tab</kbd> key, just like regular snippets. On the other hand, due to dynamic nature and extensive syntax, sometimes you may get unexpected results. This section describes how Tab handler works and how you can fine-tune it. By default, Tab handler works in a limited _syntax scopes_: HTML, XML, HAML, CSS, SASS/SCSS, LESS and _strings in programming languages_ (like JavaScript, Python, Ruby etc.). It means: * You have to switch your document to one of the syntaxes listed above to expand abbreviations by Tab key. * With <kbd>Ctrl-E</kbd> shortcut, you can expand abbreviations everywhere, its scope is not limited. * When you expand abbreviation inside strings of programming languages, the output is generated with special [output profile](http://docs.emmet.io/customization/syntax-profiles/) named `line` that generates output as a single line. To fine-tune Tab key handler, you can use the following settings in user’s `Emmet.sublime-settings` file: * `disable_tab_abbreviations_for_scopes` — a comma-separated list of syntax scopes where Tab key handler should be disabled. For example, if you want disable handler inside strings of programming languages and HAML syntax, your setting will look like this: ```json "disable_tab_abbreviations_for_scopes": "text.haml, string" ``` * `disabled_single_snippet_for_scopes` — a comma-separated list of syntax scopes where Tab handler should be disabled when expanding a single abbreviation. Currently, ST doesn’t provide API for getting list of native snippets. So, for example, if you try to expand a `php` abbreviation, it will be passed to Emmet which outputs `<php></php>` instead of PHP block as defined in native ST snippets. As a workaround, if you’re trying to expand a single abbreviation inside scope defined in `disabled_single_snippet_for_scopes` setting Emmet will look for its name inside its own [snippets catalog](http://docs.emmet.io/cheat-sheet/) first, inside `known_html_tags` setting second and if it’s not found, it allows ST to handle it and expand native abbreviation, if matched. * `known_html_tags` — a space-separated list of all known HTML tags used for lookup as described above. If you’re unhappy with Emmet tab handler behavior, you can disable i
