The open source embeddable code editor ACE is now available as version 1.0, along with a new website.

ACE, the browser-based code editor that was announced in January 2011 as the successor to Mozilla's Skywriter project, has now been released in version 1.0.

The editor, which is part of the Cloud9 IDE, is written in JavaScript and can be embedded in web pages or JavaScript applications. It has syntax highlighting for 45 languages, and can handle documents with up to four million lines of code.

The list of features supported by ACE includes Vi and Emacs keybindings; multiple cursors; code folding; vertical tab-line indicators; code markers, and search and replace with regular expressions.

The main feature of the new release is the new website, Ace.ajax.org which has a no-nonsense embedding guide, how-to reference for common operations and an API reference.

The Cloud9 blog post about the release cites the shift in ACE’s open-source philosophy by switching from the Mozilla Tri-License to the New BSD License, which they say should make it easier for developers to consider using or contributing to ACE. Matt Pardee also acknowledges that as it stands today, ACE is not fully compatible with mobile platforms like Android and iOS, adding:

“And that’s where you can help. We have created a list of remaining issues on GitHub that outlines what is lacking for full mobile support.”
