Euphoria

[ErosOlmi]

Recently I came across Euphoria programming language.

Web site at: http://www.rapideuphoria.com/

It is a script engine able to execute script files on the fly but it has also a translator to convert Euphoria scripts to C.
Anyhow, what impressed more to me was SPEED: FAST. The faster script engine I've ever seen. Not just 2/3/10 times faster than any other script engine: hundred of times.

I checked C sources and get some of the reasons why it is so fast but still looking at.
For those loving scripting and like to start in C programming, worth to have a look. Licence encourage derivative projects so perfect for personal or commercial projects.

Yeagh Euphoria is pretty amazing Eros. Not only fast, but if you look at the logic, really really neat and efficient.

Kent,

They have done a great job with a win32api include and GUI designer and IDE. (user contributions)

There is a huge library of code as well. This seems to be a well connected group.

I ran the Sieve benchmark and nothing I compared Euphoria to even came close. (compiled to C binary)

I think this is a great way to develop applications you plan to link with existing C libraries.

It's funny you don't hear much about Euphoria but it's been around for awhile.

I really have no understanding why it hasn't broken into the mainstream. I always thought it would, but it has been out for some time now as you mentioned, so it is a mystery.

[John Spikowski]

This might be a way for thinBasic to go multi-platform.

I wonder how much work it would be to port the core thinBasic engine to Euphoria and compile to C for Windows, Linux and FreeBSD versions of thinBasic.

kent,

The first example I looked at was a bit daunting. Yes; they say to use Win32Lib but that does not make it very portable to Linux. It appears the only gui portability is obtained through wx.... -> WxWidgets I presume?

Hi James,

Nice to see you here as well.

Since thinBasic is an interpreter, the GUI should be a module that user selects with a meta statement. If you running under Windows then it defaults to win32api but a GTK or wxWidget or ... could be used.

I'm just getting up to speed with thinBasic but I like the modular direction. It reminds me of ScriptBasic in a way with it's tightly integrated extension modules.

I'm interested what the thinBasic authors are thinking when it comes running the interpreter on platforms other then Windows.


John

[kryton9]

jcfuller, well winapi coding looks daunting it seems in any language, because of the way it was coded back then it seems :)

There is a page where they explain why it is easier and better than c++, that should shed light on its capabilities.
I just tinkered with euphoria from time to time and never on linux, so I can't respond to your questions about the gui, sorry.

I am researching wxWidgets compared to Qt now. Qt seems to have a buzz about it going on now and I am trying to understand why.

[kryton9]

I posted at the same time John did it seems :)

I think I have given Eros a headache all the times I bothered him with moving to another core for thinBasic to open it up to all the future devices and environments coming.
I am sure he is researching it and evaluating it, but as he mentioned many times, he wants a dependable core language as powerbasic's compiler has proven to be.

I do like how multi-line is handled in Euphoria, maybe Eros can make it so in thinBasic.

Instead of current _ as continuation for multi-line
to use , at the end of the line as in Euphoria.

[John Spikowski]

Kent,

QT is a very nice GUI toolkit and free for non commercial use. (unlike GTK and a few other GUI toolkits that can be used in commercial applications) Check out Gambas as that is what they use as a default but also supports GTK. (not fully implemented)

Can you tell me how many active thinBasic language developers (authors) there are? Will thinBasic become open source at some point?


John

[John Spikowski]

James,

Here is your example converted to C. The file exceeded 200,000 bytes and couldn't be posted here as CODE.

The resulting .exe was 132K.

Please remain on subject for the rest of this thread.

I thought I would take the simple Euphoria window demo one step further. I downloaded the win32 zip which included a bunch of demos. One of the samples was a simple window like what James was showing us but using the win32 library.

Summary:

As Eros commented in creating this thread, Euphoria is a blazing fast interpreter. I'm sure there is a way to reduce the .exe size with including only what you need before converting to C. I'm looking at Euphoria for it's CGI possibilities. If I can generate small/fast CGI programs for Linux then it may be worth learning the ins and outs of Euphoria and take a step further.

James, Eros and Kent,

I would be interested in what you guys think about Euphoria and is it a viable development tool? With all the source codes examples available on their site, somebody must think so.

John

[kryton9]

Thanks for the screenshots.

About the exe, I know in freepascal the exe's are big, but there is a utility called strip, that takes the big exe and makes it nice and small. They you can make it even smaller with upx.

I don't know if euphoria has that in their release, will need to check.

Since I am interested in 3d stuff, I am testing Java this week and will test Euphoria next week to see where it is at.
Hopefully can comment more then.

[John Spikowski]

Kent,

Thanks for the reply. I'll let you know how my CGI Euphoria to C scripts turn out and how large they are when the win32api isn't a factor.


John

[jack]

I used Euphoria many years ago in the DOS days, this thread led me to take another look.
browsed their file Archive and found that someone had compiled Euphoria as a dll, unfortunately it only
gives a very simple example, it would be interesting to use the dll as a script engine.

[John Spikowski]

Jack,

I have seen all kinds a cool examples including COM. Seems to be something for everyone on the Euphoria site.

I assume your looking for a embeddable scripting solution for a compiled application you have, correct?

You might want to have a look at ScriptBasic (http://www.scriptBasic.org) as it's embeddable and is written in ANSI C so it compiles on a wide verity of platforms. I know of a router company that uses ScriptBasic embedded in their products.

John

[kryton9]

John, thinBasic can be run from servers to be the scripting language on a server. Eros can fill you in more.
There is a test site to show it in action... will try to find it for you.

Here is the thread about it, the server seems to be not working at the moment.
http://community.thinbasic.com/index.php?topic=225.0

[John Spikowski]

Kent,

My dedicated server at a data center is running CentOS (Linux Red Hat).

ScriptBasic multi-threaded HTTPD server with in memory session support works great as a CGI application server.

I'm looking at Euphoria as a way to do C programming in a Basic like setting. Linking in other C libraries is where this is going to shine.

John

[Petr Schreiber]

Kent,

the server is http://cgi.thinbasic.com/ now.
But if John needs to run it on Linux server, I think it would not work for him ( maybe using Wine, but that is a bit unusual ).


Petr

[John Spikowski]

Hi Petr,

I'm starting to use thinBasic as a Windows utility Basic. It's like a handy power tool with a drawer full of attachments. ;)

I would never use Windows for something as critical as hosting web sites. It's fine for desktops that don't put a lot of stress on it's multi-tasking capabilities.

Open source is another requirement I have migrated to over the years and is my first choice before looking at proprietary solutions.

Here is a ScriptBasic CGI Demo (http://www.scriptbasic.org/forum/index.php/topic,2.0.html).

Back to the Euphoria topic ...

I'm Euphoria user. My comments:

Is factible to write your BASIC interpreter on Euphoria to make it more portable. The current euphoria installation includes an Euphoria interpreter 100% writed on Euphoria. This runs with acceptable speed running from source and is better after compiled. On the Euphoria archive there are some interpreters and assemblers writed on euphoria. There is a database aplication on the archive that use the "Eu on Eu" interpreter as script machine to interprete user commands. So you can write your interpreter on Euphoria using generic code non platform-dependent and compile it to get an stand-alone binary, no libraries or run time required to distribute your file.

The Euphoria as DLL is by now just a toy more than a production tool. May be in the future... You can call the functions but sometimes you must to pass to the functions pointer to your data with Euphoria internal formats.

Euphoria was for so many years a commercial shareware app, developed since 1993 by Robert Craig and Junko Miura (his wife), is a great concept but he alone arrived a point where the language was not profitable and he was not able to support the exigences of the growing community. Now is free and open source, with more people working on it, the working for Euphoria 4.0 is very active and I we must to have a beta version in next few months. So many things may change. The current pre-alpha runs on Mac OSX so will be more platforms: DOS32, WIN32, LINUX, FREEBSD and OSX.

About GUI there is not an standar, the Euphoria interpreter simply calls the OS, you can use some libraries to simplify the work. Win32lib is not portable, you can write platform specific code, or check WxEuphoria and IUP. Both are cross platform and have been used on Euphoria.

About my experience with the language, is great, one of the best thing he has is the users community have grow around. The Archive has about 1800 example programs, the more of them with source code and the main GUI libraries and the IDE have been developed by users.

Recently I came across Euphoria programming language.

Web site at: http://www.rapideuphoria.com/

It is a script engine able to execute script files on the fly but it has also a translator to convert Euphoria scripts to C.
Anyhow, what impressed more to me was SPEED: FAST. The faster script engine I've ever seen. Not just 2/3/10 times faster than any other script engine: hundred of times.

I checked C sources and get some of the reasons why it is so fast but still looking at.
For those loving scripting and like to start in C programming, worth to have a look. Licence encourage derivative projects so perfect for personal or commercial projects.

Hi Achury,

thanks for your info and opinions!
Euphoria really looks interesting, it is not first time I hear about it.

Which applications do you write using it?


Thanks,
Petr

Hi achury, welcome here.

If you are referring to thinBasic, I do not think it is a possible task.
Just thinBasic Core engine is now a more than 170000 source code project. Considering all developed modules I suppose we can go at more than 250000 lines of source code. Considering also the unique features the compiler we are using (PowerBasic) give us, it would be a no go road.

But I follow always with great interest Euphoria project. I red some of the core engine source code to get inspirations for some problems I faced in the past looking at how others have solved them.

- Mainly CGI, including, also note that all the site www.openeuphoria.org, with wiki and forum runs on euphoria CGI scripts.

- Some DOS programs to generate graphics and fractals. I'm to lazy to port them to windows, but some months ago appear a library that wrap all DOS graphic functions to windows API so I plan to port them soon.

- A lot of small scripting for automate daily work, process text files and math operations.

- A small Norton Commander clone, wich was originally for DOS but I'm fixing to become cross-platform.

Hi achury...
I dont know that is Euphoria such a powerful language ???
So where i can find this archive with source?

In the first post of this thread there is the link to the official Euphoria web site.
