We have finished Emacs syntax highlighting for JS++ in our Emacs plugin. Please note that only syntax highlighting is available for Emacs at this time. In the future, we will be including other extras such as code folding and indentation logic in the Emacs plugin.
The Emacs plugin will be distributed with the next version of JS++ (v.0.4.2) which is due next month in October.
The Emacs plugin can also be downloaded from the GitHub repository.
