Subject: ANSI(?) characters from perl debug are unwanted
Message-Id: <b7784f4d.0402060900.6d625a70@posting.google.com>
The display from perl -d is showing what i guess are ANSI display
control sequences in an Windows XP Command Prompt window.
E.g. the command line
perl -d -e 42
gives
main::(-e:1): 42
?[4;m DB<1> ?[1mq
?[0m
<I've snipped the banner lines>
This is using perl, v5.8.0 built for MSWin32-x86-multi-thread
(ActiveState build 806)
How can the ANSI output be turned off, or alternatively XP be told to
handle the ANSI correctly?
thanks
Alan

As a result those people who are not experts will *think* that if you
do "this" then the result will be "that".
Only, you really have that if you do "this" then the result will be
"that other".
Only, in the particular situation you're examining, "that" *seems*
"that other".
But when those people who are not experts will be trying to do "that"
by doing "this", they may find out that "this" doesn't do "that" and
won't understand what's going on. (And when they will understand it,
they will blame you!)
I JUST CAN'T EXPLAIN THE CONCEPT IN SIMPLER WORDS. PLEASE TELL ME IF
THERE'S ANYTHING THAT YOU CAN'T UNDERSTAND!
As an example, IIRC you wrote that "\n" causes the print() statement
to immediately print its output whereas not including it at the end of
the list of arguments causes the actual printing to be delayed. But
consider this:
$|++; # Here for some reason...
# ...
# Some code
# ...
print 'foo'; # D'Oh, it prints immediately!

You can hide drives from the My Computer windows via the registry (at least
it sounds like that's what you're trying to accomplish).
HKEY_LOCAL_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
Just add a dword value NoDrives with the appropriate value for the drive you
want to hide ( a=1, b=2, c=4, d=8, etc.). Of course, this setting will only
take effect the next time the person logs on. If you want the drive to be
hidden as soon as your script is executed, well you've got me there...

That does, indeed look wrong, but without seeing the code for
Rational, it's hard to tell. Clearly you must be overloading
stringification and ++, but if you're not overloading = as well, then
I'm confused.

I have a sun box I'd like to build cpan packages on. Uname -a tells me it is
using solaris "5.9"....I have gcc installed on the machine, but `cc` seems
to be just a shell script that does nothing.
For whatever reason, cpan seems to want to try to build c files with cc
instead of gcc. I tried symlinking cc to gcc, but that didn't work. Where
can I tell cpan to use gcc instead of cc?
Thanks,

Just a stab in the dark ....
the issue isn't with what compiler you're using - it's the 'make' you're
using. On the Sun boxes at work, I have to use gmake versus make (for
us, it's under /opt/sfw/bin, but it may be different for you).
I found out that the GNU make will use the GNU compiler - and the 'make'
setting is in 'o conf' in CPAN. A simpile 'which gmake' and 'gmake
--version' will verify this for you.
I'm hoping that does it for you.

I think you're conflating experiences where gcc is the default
compiler available with how make invokes commands.
The OP has discovered that
a) Solaris comes with no compiler
http://www.science.uva.nl/pub/solaris/solaris2.html#q6.1
b) the perl that comes with Solaris was compiled with Forte cc
("perldoc Config").
Some people have reported that building modules with gcc for
the pre-installed perl works fine, but since that perl tends
to be a bit behind the curve, others prefer to install their
own up-to-date perl, with whatever compiler suite they have
locally (so that CPAN and perl agree on the compiler
settings). You also don't run the risk of breaking how
Solaris uses its /usr/perl5 version.

The OP just got done saying he had an issue with the compiler he wanted to
use. So, he *does* have a compiler. He have two flavors on the boxes at
work - Sun's development kit has one and so do the GNU freeware packages.
Looks like he does as well - otherwise, he would not have posted to begin
with :-)

I agree that the OP *should* check to see which compiler was used to
install Perl. I presume he used the GNU compiler and built his own (since
he *does* have a compiler).
In any event - I have installed modules on Sun boxes using the GNU
compiler. And I have not seen any adverse side effects in doing so. And
using GNU's make solved the compiler issue - since the deveolpment kit's
make will want to use the development kit's compiler by default.
What was your point of your post?

No he doesn't, he said cc was a dummy shell script. Solaris
does not come with a compiler.

Unfortunately, that won't work:
perl -MCPAN -e 'install Digest::MD5'
.
.
.
cc: unrecognized option `-KPIC'
cc: language depend not recognized
cc: MD5.c: linker input file unused because linking not done
What's happening is that the config files are structured to build with cc, but
I need to change that to gcc.
I tried hacking cc to gcc in /usr/perl5/5.6.1/lib/sun4-solaris-64int/Config.pm, but that didn't work either.
Any other thoughts? Rebuild perl from source?

$i*7 and $i*8 are offsets. Your code does this if $x is 'PerlOneTwo'
sets byte #0 of y to byte #0 of x 'P'
sets byte #7 of y to byte #8 of x 'w'
sets byte #14 of y to 0 because byte #16 is outside x
extends y to 22 bytes and sets byte #21 to 0 because byte #24 is outside x
extends y to 29 bytes and sets byte #28 to 0 because byte #32 is outside x
...
extends y to 71 bytes and sets byte #70 to 0 because byte #80 is outside x
If you want to slice 7 bits from x into y, then you'd better
work with a BITS of 1 instead of 8.
Or you might find it easier to use unpack to convert the two into
binary strings, do the string manipulations, and pack the result back
together afterwards.

This is such a funny thread (though I certainly didn't intend it as such
when I posted - I really had hoped for and expected a simple sensible
answer). I don't want to say too much and get the natives any more riled
than necessary, other than to point out how amusing it is to see the
adherents of a language whose motto used to be "There's more than one way
to do it", become so catholic - that is, so obsessed with the notion that
there is only one way for things to be done.
But, anyway, the only reason I am taking time to post this is to ask what
you mean by "Lucy science". It sounds so intriguing. Does it have
anything to do with 7th Heaven?

Subject: including files in perl
Message-Id: <9b99b7f2.0402061155.685e7685@posting.google.com>
I have a list of about 100 constants that I want to use in several
files.
I have made this list of constants into a file with extension .hpl as
in .h for perl. anyways, I can use do or require to include this
file, however, the constants are not avaliable to use as if i had
declared them in the calling perl file. To use these constants, I
have to use the eval() function to so i say
KEY_PRESS(KEY_1) normally where KEY_1 is a constant;
when defining KEY_1 in another file and and calling it in function
KEY_PRESS it looks like this:
KEY_PRESS(eval(KEY_1))
I do not want to have to use eval()
why is this happening. This is not the case for variables. This is
only happening for constants. Is there a better way to include other
files into my perl programs. I need to have a comment where the perl
program goes to the file i am calling executes and stores constants
and comes back to the calling file and resumes as normal, require and
do almost do this...
please help

How are you declaring the constants? Are you declaring them with
"use constant" ? If you are, then they are becoming subroutines and
you shouldn't have to eval() them, provided they are in the correct
namespace.
