The Epeios project

The content about the Epeios project will be progressively transferred to its dedicated web site: http://epeios.q37.info.

The Epeios project: well-proven technologies for versatile, high-quality software.

The first source code was made online on may 1999 and available through public VCS since august 2000.

Some topics covered by this project:

  • XDHTML : a new way of developing user interfaces of all kinds (desktop, web, mobile…):
    • using only one language (C++; yes, even for web applications),
    • with bindings available, currently, for Java, Node.js, PHP… (http://atlastk.org/),
    • allowing to customize the appearance of the interface without writing a single line of code,
  • a new and very powerful way to handle the configuration of software components, with very easy handling of input arguments, in peculiar command-line ones (easier to use as getopt),
  • a frontend/backend communication protocol, where the backend's API is automatically generated (as C++ header, but can be applied to other languages); more about this in progress,
  • wrappers to ease the use of native code in various runtimes, in order to improve programs written in interpreted languages:
  • XPPq : an XML preprocessor, to handle file inclusion, macros and variables inside XML files, available as command-line program, but also, by using above wrappers, for Java, Node.js and PHP (comes also with an XML parser),
  • under development, also available as command-line program, and for Java, Node.js and PHP, RNCq, a rational number calculator, with absolute precision.

If you would like to support this project, there is a donations page.

Almost all Epeios software component works with GNU/Linux (and probably other POSIX compliant operating systems), macOS and Windows, on IA-32, AMD64 and ARM (AArch32 and AArch64, like those on Raspberry Pi, Banana Pi, ODROID… devices) architectures. .

You can me hire as software engineer for the conception and development of your own software components.


Atlas toolkit: writing user interfaces without framework.


  • Tools: software with command-line interface, and also (progressively) available as Java, Node.js, PHP… components.
  • Apps: software with graphical interface.

  • Compilation: instructions on how to compile Epeios software components,
  • Configuration: about the configuration of Epeios software components,
  • Installation: about the installation of Epeios software component; in progress - will supersede the above Compilation page.

  • Reminder: essentially for the developer.
