Javascript formatting for Sublime Text 2 & 3

branch: master
README.md

Summary

JsFormat is a javascript formatting plugin for Sublime Text 2. It uses the command-line/python-module javascript formatter from http://jsbeautifier.org/ to format whole js or json files, or the selected portion(s).

Features

  • javascript/json formatting (obviously)
  • all settings are customizable (whitespace, formatting style, etc..)
  • .jsbeautifyrc settings files support for even more control on a per-project basis
  • puts the cursor back in the same location it was before formatting (accounts for whitespace/newline changes)
  • Sublime Text 3 support

Settings

JsFormat uses whatever tab/indent settings are configured with the standard translate_tabs_to_spaces and tab_size sublime settings.

The following JsBeautifier settings are available in JsFormat/JsFormat.sublime-settings (defaults shown below). Check out the official jsbeautifier documentation for more details on the options:

  • indent_with_tabs: false
  • max_preserve_newlines: 4
  • preserve_newlines: true
  • space_in_paren: false
  • jslint_happy: false
  • brace_style: "collapse"
  • keep_array_indentation: false
  • keep_function_indentation: false
  • eval_code: false,
  • unescape_strings: false,
  • break_chained_methods: false*
  • e4x: false
  • wrap_line_length: 0

The following JsFormat specific settings are also exposed:

  • format_on_save: false (format files on buffer save)
  • jsbeautifyrc_files: false (see the .jsbeautifyrc files section)

I had temporary lapse of judgment a while back and merged a pull request that modified jsbeautifier. As a result, the functionality that was added from that pull request has been lost; "ensure_space_before_linestarters" is no longer supported.

The JsFormat specific ensure_newline_at_eof_on_save setting has also been removed. This functionality exists in sublime core.

jsbeautifyrc files

JsFormat now supports .jsbeautifyrc JSON files (disabled by default), which themselves support any of the exposed JsBeautifier options. The option augmentation order is: default options -> user settings -> .jsbeautifyrc option files.

A hierarchy of .jsbeautifyrc files is supported, where rc files at the deeper levels override the settings from rc files at higher levels. For example, given the file structure listed below, formatting /home/you/myProject/app.js would inherit settings from: default -> user settings -> /home/you/myProject/.jsbeautifyrc, while formatting /home/you/myProject/tests/test.js would inherit settings from: default -> user settings -> /home/you/myProject/.jsbeautifyrc -> /home/you/myProject/tests/.jsbeautifyrc

  • /home/you/myProject/.jsbeautifyrc
  • /home/you/myProject/app.js
  • /home/you/myProject/tests/.jsbeautifyrc
  • /home/you/myProject/tests/test.js

Install

Package Control (Recommended)

JsFormat is now included in the default repository channel for Package Control. It should show up in your install list with no changes.

If it does not show up, or you are on an older version of Package Control, add https://github.com/jdc0589/JsFormat as a Package Control repository. JsFormat will show up in the package install list.

Git Clone

Clone this repository in to the Sublime Text 2 "Packages" directory, which is located where ever the "Preferences" -> "Browse Packages" option in sublime takes you.

Key Binding

The default key binding is "ctrl+alt+f"

Key Binding Conflicts

Unfortunately there are other plugins that use "ctrl + alt + f", this is a hard problem to solve. If JsFormat works OK via the command palette but does nothing when you use the "ctrl + alt + f" shortcut, you have two options:

  1. Add { "keys": ["ctrl+alt+f"], "command": "js_format"} to your user keybindings file. This will override anything specified by a plugin.
  2. Find the offending plugin, and change the shortcut in its sublime-keymap file (will revert on updates)

Command Palette

Open the command palette via "ctrl + shift + p", Jsformat appears as "Format: Javascript"
