JS++ now supports the popular Ace editor library. The Ace editor is an open-source text editor plugin that is used as the underlying editor for Cloud9 IDE and is the successor to the Mozilla Bespin project.
Ace can be used for embedding JS++ snippets into web pages. It can also be used to develop tooling for JS++ such as text editors and IDEs. Ace is fully web-based so it can be used for developing cloud editing tools.
You can download the JS++ Ace integration from our GitHub.
