1. Euphoria 2.4 Alpha-test Release!
Cool! Thats alot of hard work and changes. I especially like the new
optimizations, and I cant wait to see the benchmarks. Its good to know
Rds is always pushing the envelope. Its good to see the community really
pushing for bug fixes and new features too.I like the web page also.

Hi Rob,
I would like to get the free update of the prof. ver. 2.4 (I paid for
2.3).
Thanks, and have a nice day, Rolf

Good news! Good work!
Maybe you can post to www.RapidEuphoria.com
the documentation source -- these .htx files.
You have such the files on the rds.htm page,
but they are out of date.
Good luck with Beta just tomorrow!

That's true.
It might be convenient sometimes,
but it would not, in general, be implementable with
either the Translator or the binder,
so I'd rather avoid that kind of thing.

7. Re: Euphoria 2.4 Alpha-test Release!
I was very disappointed that "a namespace qualifier is needed to resolve
<varname>" has not been improved. I must have been mistaken, 'cos I thought
you were going change this message such that it would let us know which
files we might have to explicitly include to resolve ambiguities. That is
the missing element that will make namespaces workable.

I think that's a very worthwhile enhancement.
I intend to do it for the Beta release.
I postponed that item and a couple of others,
so I could get the Alpha out sooner.

9. Re: Euphoria 2.4 Alpha-test Release!
The following code takes twice as long to run with 2.4 than 2.3
------------
include machine.e
tick_rate(1000) -- Improves precision of time()
sequence v v = {}
atom e
e =time()
for i = 1 to 10000000 do
-- wait til I get a few elements before dropping them.
if i > 1000 then
-- Drop first element.
v = v[2..length(v)]
end if
-- Append new element
v &= 1
end for
? time()-e
atom m -- Cause a pause
------------
However, as the difference is only 2.5 seconds over 10 million iterations, I
can live with it.
cheers,
Derek

On my system (Pentium II, 400 MHz, 64 MB RAM -- Win 98, DOS 7.1),
the above code takes:
o ex.exe in a DOS box
- Eu 2.3: 3.63 sec.
- Eu 2.4: 3.53 sec.
o exw.exe
- Eu 2.3: 3.44 sec.
- Eu 2.4: 8.85 sec.

Thank you for this nice birthday present! 
Here are my first experiences (DOS and Windows interpreter).
1) Installation:
- I installed Eu 2.4a into a directory with a long name
('c:\programme\euphoria'). The installation procedure then used
long names for the PATH and EUDIR variables in 'autoexec.bat'.
Shouldn't short names be used there?
- I would appreciate it, if the installation procedure made a backup
of 'autoexec.bat', before changing it. But I don't know, whether
Inno Setup can do this.
2) dir() with wildcards and a backslash at the end of the specification:
Thanks for fixing it. But now I detected an inconsistency.
- Using ex.exe, 'dir("c:\\windows\\co*\\")' returned only directories
('COMMAND','COOKIES',...), as I expected.
- Using exw.exe, 'dir("c:\\windows\\co*\\")' returned directories, and
also files!
BTW: When I run the command 'dir c:\windows\co*\' from the DOS prompt
(DOS 7.1), an error is returned, while 'dir c:\windows\co*'
works.
3) DOS LFN support:
Under Windows 98/1st ed., there is less DOS LFN support with Eu 2.4a
than with Eu 2.3:
+ = LFN supported
- = no LFN supported
| Euphoria |
Windows 98/1st ed. | 2.3 | 2.4a |
============================+=====+======+
current_dir() | - | - |
----------------------------+-----+------+
chdir() | - | - |
----------------------------+-----+------+
dir() input w/o wildcards | + | - |
input with wildcards | - | - |
output | - | - |
----------------------------+-----+------+
open() existing file | + | + |
new file | - | - |
----------------------------+-----+------+
4) I've tweaked pretty_print() a little. By just changing one line in
rPrint(), I got the nice additional possibility 4 for the first
option:
----------=----------=----------=----------=----------
procedure rPrint(object a)
-- recursively print a Euphoria object
sequence sbuff
integer multi_line, all_ascii
if atom(a) then
if integer(a) then
sbuff = sprintf(pretty_int_format, a)
-- if pretty_ascii and --* original
if 0 < pretty_ascii and pretty_ascii < 4 and --* new
...
----------=----------=----------=----------=----------
After making this change, please try for instance:
----------=----------=----------=----------=----------
include misc.e
pretty_print(1, {100, "Test", {"AB", "Huhu"}}, {4})
puts(1, "\n")
pretty_print(1, {100, "Test", {65, 66, "Huhu"}}, {4})
puts(1, "\n")
pretty_print(1, {100, "Test", {65, 66, 67}}, {4})
----------=----------=----------=----------=----------
5) Documentation of sort():
Nothing special with version 2.4, I just came across it.
I think it would be valuable to mention, whether or not the sorting
of sort() is stable, along with a short explanation for beginners,
what that means.
Thanks again for keeping up the good work with Euphoria!
Best regards,
Juergen

Thanks. I'm saving everyone's feedback

each point in detail, although I added a comment to
custom_sort() explaining that it's not "stable".
(for sort() this property is not important)

It's a low priority.
It may be convenient sometimes for 1% of the users,
(who have other ways of doing it, if they really want to)
but 99% would have a more complicated
description of define_c_func/proc to work with.
Also, I don't think it works on Linux/FreeBSD, does it?
