1. Some problems with EuServer
when i try running the run.bat it opens everything up but then i get this
error:
G:\euphoria\MyGames\Internet\win32lib.ew:68
attempt to redefine reverse - defined already in G:\EUPHORIA\include\misc.e
function reverse( sequence s1 )
Press Enter...{which closes the program}
i've already did everything that the READTHIS file said to do... [check with
Win32lib.ew and make sure its useing the one with the zip]
please if you can help, do... thanks a bunch ahead of time! =)

This happens a lot, actually, just chose one include file or the other, and
comment out
that function in it. Add a line at the top as a note to yourself that you
commented it out
and why. Make sure both functions do the same thing, or comment out the one that
does not do what your program needs.

Hi Alex & Kat,
I'm working on this very problem at the moment. There are a few routines
in win32lib that use "common" names and thus are a potential conflict with
other libraries. Until RDS resolves the silly namespace issue, we have to
be careful how we name our global entities.
I suggest that the authors of libraries that have global
functions/procedures, prefix or suffix the global procedure's name with a
short tag that identifies the library file. For example, in win32lib the
"reverse" function could have been named "w32Reverse" or "reverseW32" or
something. This does not absolutely solve the namespace issue but it
lessens the potential name conflict.
It would be nice (hint, hint, Robert) if we could say things like...
s = win32lib.reverse(s)
r = misc.reverse(r)
or even
alias reverse in win32lib.e as w32reverse
alias reverse in misc.e as miscReverse
s = w32reverse(s)
r = miscReverse(r)
or even
use win32lib.e
s = reverse(s)
use misc.e
r = reverse(r)
(Robert, have a look how namespaces are used in C#)
cheers,
Derek Parnell

As a short term solution, would it be worthwhile writing some sort of
preprocessor
that could do a search and modify on offending globals using the prefix /
suffix
idea? Run all your includes through it to search for conflicts and have it
rename
any offending globals using a prefix of the users choice?

To add to the age swap thread, I turned 36 last June, and am an AS/400
programmer at an electronics company. I've programmed in what one would
call CRT display languages for 10 years, like C, BASIC. I only recently
broken into the Windows environment programming so it is like learning all
over again. I have a great deal in programming in WinBatch.

Okay, i'll try that... thanks!

Hi Mark,
modifying a 'stamped' include file might just 'unstamp' it.

Concerning namespace syntax...
I seem to remember someone suggesting at one time a
solution that made sense to me. It's sort of a
combination of the first two solutions mentioned by
Derek. An example would be:
include win32lib.ew as w32 -- includes can be aliased
include misc.e -- but don't have to be.
s = w32.reverse (s) -- use win32lib's reverse ()
r = reverse (r) -- use misc.e's reverse ()
r = misc.reverse (r) -- also legal
All the globals in aliased includes must be prefixed with
with the alias. Globals in non-aliased includes can be
called/used normally or with a prefix of the include file
name (without extension).
