HTML, CSS, JavaScript, JSON, React and Vue code formatter for Sublime Text 2 and 3 via node.js

Sublime Text 3

JS-beautify

Node.js download

About

This is a Sublime Text 2 and 3 plugin allowing you to format your HTML, CSS, JavaScript, JSON, React and Vue code. It uses a set of nice beautifier scripts made by Einar Lielmanis. The formatters are written in JavaScript, so you'll need something (node.js) to interpret JavaScript code outside the browser.

This will work with either HTML, CSS, JavaScript, JSON, React and Vue files.

Installation

First of all, be sure you have node.js installed in order to run the beautifier. After you've installed node.js, you will need to setup this plugin.

Each OS has a different Packages folder required by Sublime Text. Open it via Preferences -> Browse Packages, and copy this repository contents to the Sublime-HTMLPrettify folder there.

The shorter way of doing this is:

Through Sublime Package Manager

  • Ctrl+Shift+P or Cmd+Shift+P in Linux/Windows/OS X
  • type install, select Package Control: Install Package
  • type prettify, select HTML-CSS-JS Prettify

Manually

Make sure you use the right Sublime Text folder. For example, on OS X, packages for version 2 are in ~/Library/Application\ Support/Sublime\ Text\ 2, while version 3 is labeled ~/Library/Application\ Support/Sublime\ Text\ 3.

These are for Sublime Text 3:

Mac

git clone https://github.com/victorporof/Sublime-HTMLPrettify.git ~/Library/Application\ Support/Sublime\ Text\ 3/Packages/Sublime-HTMLPrettify

Linux

git clone https://github.com/victorporof/Sublime-HTMLPrettify.git ~/.config/sublime-text-3/Packages/Sublime-HTMLPrettify

Windows

git clone https://github.com/victorporof/Sublime-HTMLPrettify.git %APPDATA%/Sublime\ Text\ 3/Packages/Sublime-HTMLPrettify

Usage

Tools -> Command Palette (Cmd+Shift+P or Ctrl+Shift+P) and type htmlprettify.

-- or --

Ctrl+Shift+H (or Cmd+Shift+H if you're on a Mac).

-- or --

Right click in the current buffer and select HTML/CSS/JS Prettify -> Prettify Code.

-- or --

Open a HTML, CSS, JavaScript, JSON, React or Vue file, pop out the console in Sublime Text from View -> Show Console, and type view.run_command("htmlprettify").

Writing commands in the console is ugly. Set up your own key combo for this, by going to Preferences -> Key Bindings - User, and adding a command in that array: { "keys": ["super+shift+h"], "command": "htmlprettify" }. You can use any other command you want, thought most of them are already taken.

Oh noez, command not found!

If you get an error about Node.js not being found or similar, you don't have node in the right path. Try setting the absolute path to node in HTMLPrettify.sublime-settings.

  • Ctrl+Shift+P or Cmd+Shift+P in Linux/Windows/OS X
  • type htmlprettify, select Set node Path

Simply using node without specifying a path sometimes doesn't work :(

For example, on Linux the path could be in /home/<user>/.nvm/<node version>/bin/node.

On Windows, the absolute path to node.exe must use forward slashes. Must include nodejs.exe, like so: C:/Program Files (x86)/Nodejs/node.exe

Be very careful on Linux!

Depending on your distribution and default package sources, apt-get install node (for example) will not install node.js, contrary to all human common sense and popular belief. You want nodejs instead. Best thing is to make it yourself from http://nodejs.org/#download.

Beautify Vue

To properly beautify Vue files, make sure the file syntax is recongnized by Sublime as either HTML, XML or Vue.

Beautify JSX

To properly beautify JSX files, make sure the file syntax is recongnized by Sublime as JavaScript and that e4x is true in your .jsbeautifyrc.

Beautify on Save

To beautify your code when saving the document, set the format_on_save setting to true in HTMLPrettify.sublime-settings:

  • Ctrl+Shift+P or Cmd+Shift+P in Linux/Windows/OS X
  • type htmlprettify, select Set Plugin Options

Beautify while editing (Experimental / Sublime Text 3 only)

To beautify your code when while editing a document, set the format_while_editing setting to true in HTMLPrettify.sublime-settings.

Auto-beautify when opening, focusing or bluring a file (Sublime Text 3 only)

To beautify your code when on any of these events, set the format_on_open, format_on_focus, format_on_focus_lost settings to true in HTMLPrettify.sublime-settings.

Formatting selected text only

To stop beautifying only the selected text, set the format_selection_only setting to false in HTMLPrettify.sublime-settings.

Saving to a temporary file before prettifying

Before prettifying, a copy of the the current editor's text contents are saved to a temporary file. This avoids piping the text directly to the prettifier, avoiding "filename or extension is too long" errors on Windows or any potential data lowss. To operate on the original document instead, set the save_to_temp_file_before_prettifying setting to false in HTMLPrettify.sublime-settings.

Specifying which files are allowed to be prettified

To add different file extensions use allowed_file_extensions or allowed_file_syntaxes in HTMLPrettify.sublime-settings, under the global_file_rules setting.

If the use_editor_syntax setting is false, then the following apply:

{
  "html": {
    "allowed_file_extensions": ["htm", "html", "xhtml", "shtml", "xml", "svg"],
  },
  "css": {
    "allowed_file_extensions": ["css", "scss", "sass", "less"]
  },
  "js": {
    "allowed_file_extensions": ["js"]
  },
  "json": {
    "allowed_file_extensions": ["json", "jshintrc", "jsbeautifyrc"],
  }
}

If the use_editor_syntax setting is true, then the following apply:

{
  "html": {
    "allowed_file_syntaxes": ["html", "xml"],
  },
  "css": {
    "allowed_file_syntaxes": ["css", "sass", "less"],
  },
  "js": {
    "allowed_file_syntaxes": ["javascript", "ecma"],
  },
  "json": {
    "allowed_file_syntaxes": ["json"],
  }
}

Ignoring certain files

To add ignore rules use disallowed_file_patterns in HTMLPrettify.sublime-settings, under the global_file_rules setting. If the file (including path) matches any of the regexp patterns defined in disallowed_file_patterns it will not be beautified.

The following apply regardless of the use_editor_syntax setting's value:

{
  "html": {
    "disallowed_file_patterns": ["myFileToSkip\\.html", "myFolderToSkip"]
  },
  "css": {
    "disallowed_file_patterns": ["myFileToSkip\\.css", "myFolderToSkip"]
  },
  "js": {
    "disallowed_file_patterns": ["myFileToSkip\\.js", "myFolderToSkip"]
  },
  "json": {
    "disallowed_file_patterns": ["myFileToSkip\\.json", "myFolderToSkip"]
  }
}

Ignoring certain blocks of code

Parts of code that shouldn't be formatted can be ignored with beautify preserve and beautify ignore directive comments. This allows you to tell the beautifier to preserve the formtatting of or completely ignore part of a file. The example inputs below will remain changed after beautification.

Use preserve when the content is javascript, but you don't want it reformatted.

/* beautify preserve:start */
{
    browserName: 'internet explorer',
    platform:    'Windows 7',
    version:     '8'
}
/* beautify preserve:end */

Use ignore when the content is not parsable as javascript.

var a = 1;
/* beautify ignore:start */
 {This is some strange{template language{using open-braces?
/* beautify ignore:end */

Using editor indentation settings to determine formatting style

To stop using the formatting style defined in the .jsbeautifyrc config file regarding indentation size and whether or not to use tabs or spaces, in order to use sublime's settings instead, then set the use_editor_indentation setting to true in HTMLPrettify.sublime-settings.

Using editor syntax for determining file type

To stop using editor syntax and instead use file extensions for determining file type, set the use_editor_syntax setting to false in HTMLPrettify.sublime-settings.

Respecting .editorconfig files

These configuration files can be placed wherever a .jsbeautifyrc could. To stop respecting .editorconfig files, which override the prettifier's rules, set the use_editorconfig setting to false in HTMLPrettify.sublime-settings. Note that use_editor_syntax and use_editor_indentation have precedence and will always override any other settings from any configuration file like .jsbeautifyrc and .editorconfig.

Using your own .jsbeautifyrc options

The plugin looks for a .jsbeautifyrc file in the following directories:

  1. The same directory as the source file you're prettifying.
  2. The source file's parent directories.
  3. Your home folder.
  4. Your personal Sublime settings folder.

When one is found, it stops searching, and it uses those options along with the default ones.

{
    // The plugin looks for a .jsbeautifyrc file in the same directory as the
    // source file you're prettifying (or any directory above if it doesn't exist,
    // or in your home folder if everything else fails) and uses those options
    // along the default ones.

        "package?(-lock).json":
        {
            "indent_size": 2,
            "brace_style": "collapse"
        },

        "*.sublime-@(settings|keymap|commands|menu)":
        {
            "indent_size": 4,
            "brace_style": "expand"
        }
    }
}

And here's how a .jsbeautifyrc file in your home folder could look like:

{
  "html": {
    "indent_char": "\t",
    "indent_size": 1
  },
  "js": {
    "indent_char": " ",
    "indent_size": 2
  }
}

See documentation for JS, or CSS and HTML.

A few persistent options are always applied from a .jsbeautifyrc file located in the same directory as the plugin, if not overwritten by your own .jsbeautifyrc file. Those are defined here. You can safely add stuff to that json file if you want:

  • Ctrl+Shift+P or Cmd+Shift+P in Linux/Windows/OS X
  • type htmlprettify, select Set Prettify Preferences

Thank you!
