Sublime Better Javascript

This package is an improved version of Sublime Text's JavaScript package, focused mainly on improving symbol navigation.

The default JavaScript language definition in Sublime Text has quirky symbol identification, and fills your symbols list with noise like anonymous functions, object instantiation, and even calls to console.log().

This project fixes Sublime so only named function definitions and function prototype attributes show up in the symbol list. It also fixes how these symbols are displayed in the symbol list, so that only the function names are shown.

This package has been tested on Sublime Text 2 and 3.

Installing

Install via package control (search for 'Better JavaScript').

Alternatively, cd to you Sublime packages directory, then:

git clone git@github.com:int3h/sublime-better-javascript.git 'Sublime Better JavaScript'

Refreshing the symbols of existing files

In some cases, especially with Sublime Text 3, the symbols list of files that have been previously opened may not refresh with the improved symbols.

The most reliable way I've found to fix this is to close all open JavaScript files and quit Sublime (it's important that all JS files are closed when Sublime exits.) Then delete the Index and Cache subdirectories in your Sublime user data directory (the parent of the Packages directory.) In Mac OS X, I've also had to delete ~/Library/Caches/com.sublimetext.3 (or com.sublimetext.2).

Details

The default JavaScript.tmLanguage makes some... odd decisions on what namespace to put certain tokens in. Specifically, it puts a lot of tokens in the entity.name.* namespaces that probably shouldn't be.

There is a file, Symbol List Banned.tmPreferences, in the JavaScript package which ostensibly is supposed to filter out some specific sub-namespaces from the symbols list, but it doesn't really work. I modified Symbol List Banned.tmPreferences to specifically match object instantiation and console.log calls, and set them to not show up in the symbol list.

I also modified Symbol List Function.tmPreferences to do additional processing of function names with regexes, to strip out extraneous characters (like "function" and "= function()") before showing them in the symbol list. An additional file, Symbol List Prototype.tmPreferences, was added to include function prototype attributes in the symbol list.
