- Euphoria version 1.5
- March 21, 1997
- ---------------------------
-
-
- Welcome to Euphoria! ... End User Programming with Hierarchical Objects
- for Robust Interpreted Applications
-
- Euphoria is a very-high-level programming language with the following
- features:
-
- * The language is flexible, powerful, and easier to learn than BASIC.
-
- * There is no waiting for compiles and links - just edit and run.
- However, if desired, 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.
-
- * Variable types can be as rigid or as flexible as you like. You can
- specify the precise set of legal values that may be assigned to
- any variable. You can easily write generic code that works on any
- type of data.
-
- * Euphoria is NOT an object-oriented language. It's much simpler, yet
- in many ways more powerful. Problems that require dozens of obscure
- statements in C++, can often be solved in Euphoria with just a few
- simple statements.
-
- * 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 will get a full error
- message, with a traceback and a dump of variable values - no
- mysterious machine "lockups" or crashes.
-
- * Program execution speed is 10 to 20 times faster than Microsoft
- QBasic, and 8 times faster than Sun Microsystems' Java interpreter.
- This is remarkable, given that Euphoria provides much greater
- flexibility, and run-time safety than either of those languages.
-
- * Euphoria programs are not constrained by any 640K or 64K memory
- restrictions for which MS-DOS is infamous. You can use all of the
- multiple megabytes of extended memory on your system seamlessly,
- and if that isn't enough, Euphoria will use a swap file on disk to
- page chunks of memory in and out based on a least-recently-used
- algorithm.
-
- * An integrated, easy-to-use, full-screen source-level debugger/tracer
- is included.
-
- * Both a statement-count profiler, and a time profiler are included.
-
- * A full-screen, multi-file editor with color syntax highlighting and
- auto-completion of Euphoria statements is provided, complete
- with Euphoria source code that you are free to modify.
-
- * A large collection of interesting demo programs written in Euphoria
- is provided.
-
- * There is a rapidly growing collection of 3rd party programs and
- libraries. See WEB.DOC
-
- * The implementation of Euphoria on MS-DOS is full and complete.
- If necessary, you can access DOS software interrupts. You can call
- machine-code routines. You can even set up your own hardware
- interrupt handlers. Several high-speed action games, complete with
- Sound Blaster sound effects have been developed 100% in Euphoria,
- without the need for any C/C++ or machine code. Some of these games
- are now entering commercial distribution.
-
- Who would benefit from using Euphoria?
-
- * novices / students
- - Euphoria is one of the simplest and easiest of all
- languages to learn.
- - Euphoria shields you from machine-level issues such as
- memory addresses, number of bits in a byte etc.
- - Euphoria does more error checking than any other popular
- language.
- - Euphoria never leaves you with a crashed machine -
- you'll always get a clear explanation of what went wrong
-
- * hobbyists
- - take a look at some of the interesting games and
- high-speed graphics demos we've written, then visit
- the Web and download some even better games and demos
- written by Euphoria users.
- - do you really want to invest the time and money
- needed to learn C++?
- - do you really enjoy spending your weekends tracking
- down subtle pointer corruption bugs?
-
- * professionals/businesses
- - You can develop a reliable, maintainable, fully-debugged
- program in *much* less time in Euphoria than in C/C++.
- - The level of experience and machine knowledge required
- to use Euphoria is much lower than for C/C++. You won't
- have to hire high-priced programmers. You can do the job
- yourself, or hire lower-priced people.
- - take a look at include\sort.e. Can you write a
- generic routine this easily in C++?
- - See demo\mydata.ex. Can you set up a simple database this
- easily in any other language?
- - Euphoria can be used as a sophisticated batch file
- language.
- - Euphoria is great for quick, easy development of file
- filters and other utilities.
- - You can distribute your program royalty-free as a .exe file.
-
- Euphoria comes in two different editions: a Public Domain Edition and a
- Complete Edition. Both editions will run any Euphoria program of any size at
- full speed, and will report all "compile-time" errors such as syntax errors,
- undeclared variables etc. The only restriction in the Public Domain Edition
- is that full diagnostic information for run-time errors is not provided
- for large programs.
-
- For programs up to 300 statements in size you will enjoy the full support of
- Euphoria's excellent debugging facilities. Blank-lines and comments are not
- counted, and the standard include files are free (if not bound or "shrouded").
- You can put many statements on one line, or you can split a statement across
- many lines -- it won't affect your statement count.
-
- For larger programs, a run-time error will cause your program to halt
- with just a brief message. The usual fully-detailed diagnostics with a dump
- of variable values and other debugging information will not be provided.
- However, the source debugger and profiler will remain fully operational,
- and you can insert debug print statements the way you would in C/C++ or other
- languages. In C/C++ very few run-time errors are even detected (until your
- machine locks up, crashes, or you get a "GPF"). Your productivity will remain
- much higher in Euphoria, given the run-time safety, flexibility and expressive
- power of the language, plus the fact that you won't waste time compiling and
- linking.
-
- We want you to enjoy writing some great programs in Euphoria. When you
- decide that you like the language, and want to save time developing
- large programs, we hope you will decide to purchase the latest Complete
- Edition, and the desktop-published printed manual. See doc\register.doc for
- details, or run doc\how2reg.ex.
-
- An ASCII text version of the complete Euphoria Reference Manual is in
- doc\refman.doc and doc\library.doc. To save time, just type: guru
- to search for subjects that you are interested in.
-
- The Public Domain Edition of Euphoria, in its entirety, is being placed
- in the Public Domain. This includes the Public Domain version of the
- compiler/interpreter "ex.exe" and all of the demo programs, including the
- editor. There's 15,000 lines of free Euphoria source code in this package.
- We encourage you to use it, copy it, modify it, distribute it, upload it etc.
-
- You are free to distribute the Public Domain Edition, without royalty, so
- anyone can run a Euphoria program that you have developed. You can even
- bind your Euphoria program with a copy of ex.exe to make a single, stand-alone
- .exe file.
-
- You may *not* distribute the version of the file "ex.exe" that comes with
- the Complete Edition.
-
- To run Euphoria you must have MS-DOS (or PC-DOS etc.) on any 386 or higher
- processor. Euphoria will use extended memory if it is available, but can run
- in 640K of conventional memory if that is all you have. It has been well
- tested under MS-DOS 4, 5, 6, 6.2 and 7.0, Windows 3.1, Windows 3.11,
- Windows NT, Windows 95 and OS/2. If the Public Domain Edition runs on your
- machine, the Complete Edition will also run. Euphoria exploits the full
- 32-bit power of your PC. A Euphoria program will run under DOS, or as a
- DOS application under Windows or OS/2 - just double-click on the file name,
- or open a DOS prompt window. A Windows WIN32 API version of Euphoria is under
- development, and a Linux version is planned.
-
- What's in this Public Domain release:
-
- subdirectory (after installing)
- BIN - Euphoria (ex.exe), search, guru, bind, and more
-
- INCLUDE - standard .e include files
-
- DEMO - games, benchmarks and other Euphoria programs that
- you can run to check out Euphoria
-
- \LANGWAR - real-time action space wars game
- \BENCH - benchmark programs and results
-
- DOC - documentation files, including the complete
- Reference Manual
-
- REGISTER - information on ordering the Complete Edition, and a
- program (HOW2REG) to help you register
-
- You can run some of the programs without installing Euphoria, but you really
- should run install.bat to organize the files into subdirectories and
- set yourself up properly. Some programs will not run until you have
- installed.

- Notice to Shareware Vendors:
- We encourage you to distribute this Public Domain Edition of Euphoria.
- You can charge whatever you like for it. It is not shareware in the
- usual sense. People can use Euphoria for as long as they like without
- obligation. We make money from those who start to seriously develop large
- applications, and want to get the latest release, with printed manual,
- and enhanced debug support for large programs.
