Crusty:
Which version did you download version 3.11 or version 4 ?
ver 3.11 is older stable version ver 4.0 is a new alpha version.
If you download the Linux binary it does not contain those
files. ex.exe ( is DOS interpreter ) exw.exe ( is WINDOWS interpreter )

Here are the descriptions

Filename Description

eu40a3.zip Euphoria for DOS only

euphoria_40a3.exe Euphoria for Windows (includes DOS support)

euphoria-4.0a3.tar.gz Euphoria for Linux

euphoria-osx-4.0a3.tar.gz Euphoria for OS X

euphoria-src-4.0a3.tar.gz Source packaged as .tar.gz

euphoria-src-4.0a3.zip Source packaged as .zip

The "src" versions will be more work to get started.

Downloading version 3 is still a good choice for "just getting started", get it from the RapidEuphoria website (see tab at the top of the page.)

You can even help me out! Download "Think Euphoria" from the RapidEuphoria website. Its only a first draft, but anything you do not understand I will be able to fix.

This is the downside to the SF.net file listings. There is no place to state what is what, other than platform and file extension. You have downloaded the source only release which contains no executables, it is for those with an existing Euphoria who want to build 4.0 from source. You should download either the 3.1 from RapidEuphoria or download euphoria_40a3.exe. Now, I am assuming you are on the Windows platform.

Win32Lib is a library of functions and procedures which allow the Euphoria programmer to MUCH more easily write WINDOWS programs, similar to what you have indicated you might like to do.

I think the GUI file you're refereing to is the IDE, which is a visual elaboration or derivation of the Win32Lib library, which allows you to click on various aspects of Windows program features, "controls", and place them directly into a program with very little coding required. In fact, there is in the IDE a CALENDAR control that you can just "put" into a program that will pretty much do what you want right out of the box. That is, controls like that have a built-in functionality without having to write any code to implement that functionality. Put the calandar control into a window in the IDE, run the resulting program created for you by the IDE, and you will see a calendar, with month/year selections, etc, without writing a single line of code!

Pretty spiffy, right?

Hi

What you should have done (and I believe this should apply to all newcomers of the language) is download

http://downloads.sourceforge.net/rapideuphoria/Eu3.1-Win32Setup.exe?use_mirror=

This is on th RDS website, but is more difficult to see than e31setup.exe (or whatever its called). It installs the same euphoria, and win32, and sets then environment variables without the need for a reboot.

Perhaps a request for equal billing to the original setup?

Thanks everyone. I think I shall have to delete everything and start again. I did download win32lib but guessed wrongly where the files should be installed. So I did another download and guessed right. (BIN/INCLUDE) would have been quite nice if someone had said where the files should reside. Tried to find the IDE file. Found a couple of places (including Judith Evan's IDE) but the links are broken.

Surely, it should be just a bit easier for the 'newbie'?

I will start again from scratch. Regards and thanks alec

Sorry about this. MAybe it should be a new thread. Done everything suggested and I'm now 'running'. Well, staggering might be a better description of progress.

PROBLEM. Most of the demo ???.ex files I try to run don't! All I get is a quicl flash of the dos panel on the screen. Frustrated.

I tried this.

position(10,10)

puts(1,"More hello world") puts(1, "\n\n") puts(1, "\nPress Enter. (q to quit) ") while TRUE do k = get_key() if k = 'q' then abort(0) elsif k != -1 then exit end if end while

Some examples don't do that but I can't see where the difference lies.

Thanks alec

I tried this. 
-------------------- 
-- HELLO1.ex 
 
position(10,10) 
 
puts(1,"More hello world") 
puts(1, "\n\n") 
    puts(1, "\nPress Enter. (q to quit) ") 
    while TRUE do 
	k = get_key() 
	if k = 'q' then 
	    abort(0) 
	elsif k != -1 then 
	    exit 
	end if 
    end while

Hi Alec:
What is flashing on your screen is a error message.
Because you are running a DOS program in Windows the interpreter
is flashing an error message up on the screen an closing the window.
If you look in the directory where you are running your
program.You will see a text file called ex.err which contains
the error information.
If you are trouble shooting a DOS program in Windows and
you want to see whats flashing on the screen.
You can place:

if getc(0) then 
-- pause 
end if 

at the end of your program
which will keep the DOS window open until you hit a key.

-------------------- 
-- HELLO1.ex 
-- You need a constant because TRUE is not a keyword. 
 
constant TRUE = 1 
-- You need a variable to hold key.  
integer k 
 
position(10,10) 
 
puts(1,"More hello world") 
puts(1, "\n\n") 
    puts(1, "\nPress Enter. (q to quit) ") 
    while TRUE do 
k = get_key() 
if k = 'q' then 
    abort(0) 
elsif k != -1 then 
    exit 
end if 
    end while 
--------------------

Crusty, this thread is fine.

When you try to run the demos, are you clicking on them? If so, do you have the relevant interpreters associated with the file types to run them? What I mean is, *.ex demos need to be run by ex.exe, and windows *.exw demos need to be run by exw.exe. Both interpreters are found in the bin folder. I'm presuming you know how to associate a program with file types, if not, ask here.

I have a question re win32lib vs wxEuphoria.
If I write a pgm using wxEuphoria, it will be crossPlatform.
Whereas if I write a pgm using win32lib it will not be crossPlatform.
Thanks in advance

This wasn't a question, but is basically true. There are some issues that you have to look out for, like path separators (Windows uses \, Linux uses /). Some controls may behave slightly differently on different platforms. This is mainly because wxWidgets uses native controls. So they usually behave the way you'd expect, if you know what to expect on the respective platform.

Matt, I have run from the command line. and double click on the file name and clicking on ex.exe and entering the file name when asked to do so and from a dos envirinment. and using the 'run' tab in my editor!

In an effort to be brief I haven't explained myself very well.

When I run a file, say csort.ex, (however I do it!) the dos box flashes on the screen and then closes.

Inspecting the file (say csort.ex) it is clear why this should be. Once the file has executed the dos box closes. There's nothing to prevent it. Some files such as queen.ex do run correctly because they wait for the user to press a key. csort.ex doesn't.

As examples to help the beginner, files such as hello.ex and csort.ex are quite useless.

I can make them halt execution and leave a visible 'box' by adding include get.e at the head of the file and

k= wait_key() at the end of the file.

BUT, it's absurd to find example files (for newbies?) that run but don't leave a dos box visible to the user. SO, I assumed that I must be missing something and hence my cry for help.

sanity.ex DOES work and tells me that PASSED is 100%!

I have downloaded David Gay's tutorial and Refman. Frankly, comparing them with my old 'C' programming manual and a more up to date PHP manual, they aren't very good are they? If Euphoria is to become more popular, then the documentation needs considerable improvement don't you think?

Even the consolidated download of Euphoria, win32lib doesn't put the files in the correct folders! I had to duplicate several of the *.e files because the EX.ERR file tole me they couldn't be found in the expected folders. It could put a begginer off don't you think. Actually, I intend to delete the lot and start again.

If anyone is interested in my opinion, particularly the writer of REFMAN, I'd be happy to put in my two penny's worth.

Thanks everyone. Miserable old Crusty

Tom,

Yes I have downloaded Think Euphoria. And I've ploughed through some of it but not all.

I do have comments to make. Lots of them Not sure about protocol but the only way I can make my comments is by having direct contact with you. Is that permissible?

When in my 40's and 50's, I did write a few technical 'manuals'. Not I hasten to add on programming but my thoughts may be of some use to you. I've done 'basic', 'C', 'PHP' and even did some machine code. Euphoria is 'easy' isn't it? It sure isn't using the existing tutorials I've got hold of. It's just totally frustrating.

Tom, I have no axe to grind. You are welcome to my thoughts. Regards alec
