Hypersoft-Systems: U.-S.-A.: JSE (Java-Script-Engine) is a free (as in cost of purchase) and open-source computer software project for executing shell-scripts written in JavaScript as full-fledged-software-programs within a Linux Operating System environment.
JSE is conceptualized and maintained by Hypersoft-Systems: U.-S.-A. (Triston J.Taylor).
Donations in support of this project are welcome and are processed via pay-pal.
In general, JSE IS a full-fledged-application-development-suite. If JSE does not have the functionality you require built-in, you can simply create a plugin written in the C programming language (or compatible) to provide the needed functionality. In fact, JSE itself is built on the use of plugins and scripts to provide all of its core functionalities.
- Let JavaScript do Unix things, in The Unix Way
- JavaScript interpretation as a System Level coding package
- HTML Browsing as a System Level application package
- Zero external runtime environment support requirements (package tools, script-libraries, etc.)
JSE itself, depends upon several technologies to achieve its design goals.
- WebKitGTK+ 4.0 (for JavaScript interpretation and HTML Rendering)
- DynCall 0.8 [built-in]
- GNU ReadLine (for interactive-sessions)
- GCC (C compiler and linker suite)
- GNU Make
- BSD pkgconf (also known as pkg-config)
JSE's build environment adds a few requirements:
- Bash Shell 4.0+
- wget [to download the DynCall library package and documentation]
- Git [if you use software revision control]
- Tar and Zip support [for unpacking the DynCall archive and creating archives]
JSE has a host of licensing options for you to choose from. The project does not wish for legal issues to be the cause of not using JSE, so the license for JSE is very loose. Please review the licensing for all other included technologies, if you are experiencing a legal permissions issue.
JSE provides many features to enhance your ability to write JavaScript based shell-scripts and HTML Applications for the Linux platform. You can use JSE to do any of the following:
- Write Basic JavaScripts (With JSE's Shell support)
- Write Advanced JavaScripts (Using shared-system-libraries and JSE Plugins)
- Create, Design and Debug: HTML Applications (with Advanced or Basic JavaScripting support)
- Interactive Session (basic-example)
You can very easily add JSE support to your OS with the following script, provided you meet the system requirements.
wget -O jse.zip https://github.com/hypersoft/jse/archive/3.1.zip &&
unzip jse.zip &&
mv jse-3.1 jse &&
cd jse &&
make && sudo make install && demo/testbed;You can very easily add JSE support to your OS with the following script, provided you meet the system requirements.

mv jse-master jse &&

This Screenshot demonstrates the Awesomeness of JSE and its Ghtml counter-part. The application shown within Ghtml is a manual JavaScript testing application which is distributed with the source code of JSE, and can be found in the ./test folder.
Powerful applications can easily be written in no-time-at-all using JSE and Ghtml. To execute the application shown in the Screenshot yourself, simply run:
$ demo/testbed
from a terminal session within the project's root directory after compiling and installing the project.
JSE is a formidable coding platform. So formidable that it could INSTANTLY be as dangerous as allowing full command access to a C compiler. To protect host systems, JSE employs a simple-file-system-security-contract:
- Pipes will not be executed with enhanced execution features or plugins
- A user must have execute permission on the file being executed to enable enhanced execution features and plugins
Note: A developer may specify that remote content be loaded, from within an executable file. This is an intentional security leak on behalf of the execution of the developer's implementation. Neither Ghtml nor JSE will attempt to prohibit downloading or execution of remote content, and no sand-boxing-implementation of mixed content is provided by this project at this time.
