Euphoria Programming Language
Euphoria has come a long way since v1.0 was released in July 1993. There are
now thousands of users around the world.
There's an automated
discussion forum, managed and moderated by a Euphoria
program, and supporting over 500 subscribers.
The Euphoria Web site contains
over 1600 contributed .zip files packed with Euphoria source programs
and library routines. Dozens of people have set up their own independent Web
pages with Euphoria-related content.
Euphoria has been used in a variety of
The Windows version has been used
to create numerous GUI, utility and
The DOS version has been used to create
many exciting high-speed action games,
complete with Sound Blaster sound effects.
FreeBSD versions have been used to
write X Windows GUI programs, Web-based (CGI) programs, and lots of
useful tools and utilities.
Yet Another Programming Language?
Euphoria is a very-high-level programming language with several features that
set it apart from the crowd:
Euphoria programs run on
Euphoria is free and
The complete source code for the Euphoria interpreter, translator
and binder is included in the download package.
The language is flexible, powerful, and easy to learn.
There is no waiting for compiles and links - just edit and run.
You can create and distribute a royalty-free,
stand-alone .exe file.
Dynamic storage allocation is
fundamental to Euphoria. Variables grow or shrink in size without the
programmer having to worry about allocating and freeing chunks of memory.
Elements of an array (Euphoria sequence) can be a dynamic mixture of
different types and sizes of data.
Euphoria provides extensive run-time error
checking for: out-of-bounds subscripts, uninitialized
variables, bad parameter values for library routines, illegal value assigned
to a variable, and many more. If something goes wrong you'll get a full error
message, with a call traceback and a listing of variable values.
With other languages you'll typically get protection faults
with useless dumps of machine registers and addresses.
The Euphoria interpreter is more than
30 times faster than either Perl or Python, and it's
considerably faster than all other interpreted languages, according to the
"Great Computer Language Shootout" benchmark (see demo\bench\bench.doc).
If that isn't enough, there's a Euphoria To C Translator that can
translate any Euphoria program to C, and boost your speed even more.
Why waste time debugging hand-coded C/C++? You can easily develop a Euphoria
program, and then generate the C code.
Euphoria programs are not constrained by any 640K memory restrictions
for which MS-DOS is infamous. All versions of Euphoria let you use
all the memory on your system, and if that isn't
enough, a swap file on disk will provide additional virtual memory.
An integrated, easy-to-use, full-screen
source-level debugger/tracer is included.
Both an execution-count profiler, and a
time profiler are available.
There is a large and rapidly growing collection of excellent 3rd party
programs and libraries, most with full source code.
RDS has developed an extremely flexible database
system (EDS) that is portable across all Euphoria platforms.
The WIN32 implementation of Euphoria
can access any WIN32 API routine, as well as C or
Euphoria routines in .DLL files.
A team of people has developed
a Windows GUI library (Win32Lib), complete
with a powerful Interactive Development Environment.
You can design a user interface graphically, specify the
Euphoria statements to be executed when someone clicks,
and the IDE will create a complete Euphoria program for you.
There are Windows Euphoria libraries for Internet access,
3-D games, and many other application areas.
The DOS32 implementation of Euphoria
on MS-DOS contains a built-in graphics library. If necessary, you can
access DOS software interrupts. You can call machine-code routines.
You can even
set up your own hardware interrupt handlers. Many high-speed action
games, complete with Sound Blaster sound effects, have been developed 100%
in Euphoria, without the need for any machine code.
The Linux and
FreeBSD implementations of Euphoria
let you access C routines and variables in shared libraries,
for tasks ranging from graphics, to X windows GUI programming, to
Internet CGI programming. The good news is, you'll be
programming in Euphoria, not C.
Platforms and Products
Euphoria runs on four different platforms,
This Euphoria Interpreter, Translator and Binder
package is free for anyone to use.
Using the Euphoria Binder you can
(encrypt) and bind any Euphoria program
with a copy of the interpreter back-end, to create a
single, stand-alone, tamper-resistant
.exe file for easy distribution. See bind.doc)
The Euphoria To C Translator converts any Euphoria program
into a stand-alone
.exe file, but it has the added advantage of boosting the program's speed
as well. To use it, you must have one of 7 free C compilers installed on
your machine, but no knowledge of C is required.
The documentation contained in this package comes in both plain text and
HTML form. The plain text (.doc) files can be viewed with any text
editor, such as Windows NotePad or WordPad. The HTML (.htm) files
can be viewed with your Web browser. A tool that we developed in Euphoria
allows us to automatically generate both plain text and HTML files, from a
common source. Thus the content of each file in the
doc subdirectory should be identical
to the content of the corresponding file in the
html subdirectory, aside from the
lack of links, fonts, colors, etc. See
(or html\overview.htm) for a summary
of the documentation files.
You can freely distribute the Euphoria interpreter, and any other files
contained in this package, in whole or in part, so anyone can run a Euphoria
program that you have developed. You are completely free to distribute
any Euphoria programs that you write.
To run the WIN32 version
of Euphoria, you need Windows 95 or any later version of Windows.
It runs fine on XP.
The DOS32 version will run on
any version of Windows, and will also run on plain DOS
on any 386 or higher processor. Contrary to popular opinion, DOS is
not dead. You can run DOS Euphoria programs on Windows XP in a
command prompt window.
To run the Linux version of Euphoria
you need any reasonably up-to-date Linux distribution, that has libc6 or
later. For example, Red Hat 5.2 or later will work fine.
To run the FreeBSD version of Euphoria
you need any reasonably up-to-date FreeBSD distribution.
||The Euphoria interpreter is an engine for running
Euphoria programs. It does not have a fancy GUI interface.
When you are ready to do Windows GUI
programming, you should download Judith Evans' IDE (written in open source
Euphoria code). It will provide you with a very nice graphical
environment for Windows programming. For most other programming,
all you really need is an editor, such as NotePad.
