HTML, CSS, JavaScript and JSON 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 and JSON 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 and JSON 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 or JavaScript 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 sh: node: command not 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 Debian!

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 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

Preserving selection after formatting

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

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 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. Here's an example of how it can look like.

These are the default options used by this plugin:

{
  // Details: https://github.com/victorporof/Sublime-HTMLPrettify#using-your-own-jsbeautifyrc-options
  // Documentation: https://github.com/einars/js-beautify/
  "html": {
    "allowed_file_extensions": ["htm", "html", "xhtml", "shtml", "xml", "svg"],
    "brace_style": "collapse", // [collapse|expand|end-expand|none] Put braces on the same line as control statements (default), or put braces on own line (Allman / ANSI style), or just put end braces on own line, or attempt to keep them where they are
    "end_with_newline": false, // End output with newline
    "indent_char": " ", // Indentation character
    "indent_handlebars": false, // e.g. {{#foo}}, {{/foo}}
    "indent_inner_html": false, // Indent <head> and <body> sections
    "indent_scripts": "keep", // [keep|separate|normal]
    "indent_size": 4, // Indentation size
    "max_preserve_newlines": 0, // Maximum number of line breaks to be preserved in one chunk (0 disables)
    "preserve_newlines": true, // Whether existing line breaks before elements should be preserved (only works before elements, not inside tags or for text)
    "unformatted": ["a", "span", "img", "code", "pre", "sub", "sup", "em", "strong", "b", "i", "u", "strike", "big", "small", "pre", "h1", "h2", "h3", "h4", "h5", "h6"], // List of tags that should not be reformatted
    "wrap_line_length": 0 // Lines should wrap at next opportunity after this number of characters (0 disables)
  },
  "css": {
    "allowed_file_extensions": ["css", "scss", "sass", "less"],
    "end_with_newline": false, // End output with newline
    "indent_char": " ", // Indentation character
    "indent_size": 4, // Indentation size
    "newline_between_rules": true, // Add a new line after every css rule
    "selector_separator": " ",
    "selector_separator_newline": true // Separate selectors with newline or not (e.g. "a,\nbr" or "a, br")
  },
  "js": {
    "allowed_file_extensions": ["js", "json", "jshintrc", "jsbeautifyrc"],
    "brace_style": "collapse", // [collapse|expand|end-expand|none] Put braces on the same line as control statements (default), or put braces on own line (Allman / ANSI style), or just put end braces on own line, or attempt to keep them where they are
    "break_chained_methods": false, // Break chained method calls across subsequent lines
    "e4x": false, // Pass E4X xml literals through untouched
    "end_with_newline": false, // End output with newline
    "indent_char": " ", // Indentation character
    "indent_level": 0, // Initial indentation level
    "indent_size": 4, // Indentation size
    "indent_with_tabs": false, // Indent with tabs, overrides `indent_size` and `indent_char`
    "jslint_happy": false, // If true, then jslint-stricter mode is enforced
    "keep_array_indentation": false, // Preserve array indentation
    "keep_function_indentation": false, // Preserve function indentation
    "max_preserve_newlines": 0, // Maximum number of line breaks to be preserved in one chunk (0 disables)
    "preserve_newlines": true, // Whether existing line breaks should be preserved
    "space_after_anon_function": false, // Should the space before an anonymous function's parens be added, "function()" vs "function ()"
    "space_before_conditional": true, // Should the space before conditional statement be added, "if(true)" vs "if (true)"
    "space_in_empty_paren": false, // Add padding spaces within empty paren, "f()" vs "f( )"
    "space_in_paren": false, // Add padding spaces within paren, ie. f( a, b )
    "unescape_strings": false, // Should printable characters in strings encoded in \xNN notation be unescaped, "example" vs "\x65\x78\x61\x6d\x70\x6c\x65"
    "wrap_line_length": 0 // Lines should wrap at next opportunity after this number of characters (0 disables)
  }
}

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

Specifying your own file extensions

To add different file extensions use allowed_file_extensions in the .jsbeautifyrc file:

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

Thank you!
