Improving Windows Integration

We are working to improve Windows integration for JS++.

The first piece of good news is, beginning from the next release of JS++ (v.0.4.2), a system restart will no longer be necessary to complete the installation of JS++.

Secondly, to improve usability, we are adding context menu support for compiling *.jspp and *.jpp files:

JS++ Windows Context Menu

All of this will become available on the next release (v.0.4.2), which we are estimating to be around late September/early October.

Embed JS++ Code and Snippets into Web Pages

You can now embed JS++ code and snippets into your web pages. We have support for the JavaScript Syntax Highlighter by Alex Gorbatchev and CodeMirror.

The JavaScript SyntaxHighlighter project by Alex Gorbatchev has been around for a while and is used by Apache, Mozilla, Yahoo, WordPress, among others. It’s actually used right here on this website for highlighting JS++ code.


The CodeMirror plugin can be used for embedding JS++ code and snippets on your website. However, CodeMirror is also the text editor plugin for popular editors too. Projects like Adobe Brackets use CodeMirror as its underlying text editor. Thus, the JS++ CodeMirror plugin can be used for creating your own text editor or IDE that supports JS++ in addition to embedding snippets on your web pages.

JS++ Plugin for Geany

Geany integration is now available for JS++. The Geany plugin will be released with the next version of JS++, but you can download from GitHub now.

JS++ Plugin for Geany Editor

The plugin for Geany is somewhat limited. At Onux, we want to provide maximum editor and IDE integration for JS++. Geany markets itself as a “lightweight IDE” rather than just a text editor. To this end, we wanted to provide symbol navigation, a custom lexer, etc. However, in order for us to provide these features in Geany, we would have to build and distribute our own Geany. This was not ideal, and we unfortunately had to compromise.

We had to settle for the C lexer and deal with its limits for JS++; otherwise, we would have to modify Scintilla (the underlying text editor for Geany), write a custom lexer, and re-build Geany.

Nevertheless, in Geany, you currently get syntax highlighting and compiler integration. If we can provide deeper integration without compromising convenience, we absolutely will.

Kate and KWrite Integration for JS++

We just gave you GNOME integration for Linux yesterday via gedit. Today, we’re giving you KDE integration via Kate and KWrite.

Kate Text Editor

The Kate and KWrite plugins will be included in the next release of JS++, but you can download the plugin today from GitHub.

Once installed, the plugin will be valid for both Kate and KWrite. The plugin provides syntax highlighting, code folding, TODO comments, and documentation comment support for Kate and KWrite.

The plugin is theme-independent. Thus, some keywords are simply bolded rather than being colored with a specific style. If your font does not support bolding, it may appear much of the syntax is not being highlighted. For example, Kate and KWrite on Kubuntu will use the “Oxygen Mono” font as the default font for most themes. “Oxygen Mono” does not support bolded text and switching the font to “Ubuntu Mono” will fix this problem.

gedit Integration

We now have gedit integration for JS++. The gedit plugin provides full syntax highlighting support, including support for highlighting invalid keywords. The JS++ plugin for gedit is more accurate than the default JavaScript plugin that ships with gedit for highlighting JavaScript (especially for regular expression syntax highlighting).


The feature for highlighting invalid keywords is useful if you come from a background like Java and expect the exact same syntax and aren’t quite aware of the subtle differences. For instance, class inheritance in JS++ uses a syntax similar to C++ and C#:

class Foo : Bar {}

If you accidentally use extends, you’ll be notified immediately:

gedit error

The gedit plugin will be distributed with the next version of JS++. If you want to download the gedit plugin early, you can download it from GitHub.
