hi people,
I have a function which I am passing a stream which is basically postfix notation
if(isdigit(in.peek()))
{
in >> number;
nums.push(number);
}
else if (strchr("+-*/", in.peek( )) != NULL)
{
in >> symbol;
do_operation(symbol, nums, okay);
}

Hi, does anyone know how to ignore whether a number is negative in a script. E.g. if I have a variable that contains -1200, how do I ignore the minus sign? (1 Reply)
Hi All,
Just faced an interesting thing in HP-UX. I was dividing 2955334616 / 2 by using echo `expr 2955334616 / 2` , and this ofcourse which expects 1477667308 to be returned. But I am getting -669816340 and I am :wall: how exactly this is possible. It is not one of the compliments (Ones or... (4 Replies)

Apache::TestMM(3) User Contributed Perl Documentation Apache::TestMM(3)NAME
Apache::TestMM - Provide MakeMaker Wrapper Methods
SYNOPSIS
require Apache::TestMM;
# import MY::test and MY::clean overrides for MM
Apache::TestMM->import(qw(test clean));
# parse command line args
Apache::TestMM::filter_args();
# autogenerate the script
Apache::TestMM::generate_script('t/TEST');
DESCRIPTION
"Apache::TestMM" provides wrappers for the "ExtUtils::MakeMaker" craft, making it easier to extend the autogenerated Makefile with
"Apache::Test".
FUNCTIONS
"import"
use Apache::TestMM qw(test clean);
or:
Apache::TestMM->import(qw(test clean));
Imports "MY::" overrides for the default "ExtUtils::MakeMaker" test and clean targets, as if you have defined:
sub MY::test {...}
sub MY::clean {...}
in Makefile.PL. "Apache::TestMM" does this for you so that these Makefile targets will run the Apache server and the tests for it, and
clean up after its mess.
"filter_args"
push @ARGV, '-apxs', $apxs_path;
Apache::TestMM::filter_args();
WriteMakefile(...);
When "WriteMakefile()" is called it parses @ARGV, hoping to find special options like "PREFIX=/home/stas/perl". "Apache::Test" accepts a
lot of configuration options of its own. When "Apache::TestMM::filter_args()" is called, it removes any "Apache::Test"-specific options
from @ARGV and stores them internally, so when "WriteMakefile()" is called they aren't in @ARGV and thus won't be processed by
"WriteMakefile()".
The options can be set when Makefile.PL is called:
% perl Makefile.PL -apxs /path/to/apxs
Or you can push them manually to @ARGV from the code:
push @ARGV, '-apxs', $apxs_path;
When:
Apache::TestMM::generate_script('t/TEST');
is called, "Apache::Test"-specific options extracted by "Apache::TestMM::filter_args()" are written to the autogenerated file. In our
example, the autogenerated t/TEST will include:
%Apache::TestConfig::Argv = qw(apxs /path/to/apxs);
which is going to be used by the "Apache::Test" runtime.
The other frequently used options are: "-httpd", telling where to find the httpd (usually when the "-apxs" option is not used),
"-libmodperl" to use a specific mod_perl shared object (if your mod_perl is built as DSO), "-maxclients" to change the default number of
the configured "MaxClients" directive, "-port" to start the server on a specific port, etc. To get the complete list of available
configuration options and their purpose and syntax, run:
% perl -MApache::TestConfig -le 'Apache::TestConfig::usage()'
You may wish to document some of these in your application's README file, especially the "-apxs" and "-httpd" options.
"generate_script"
Apache::TestMM::generate_script('t/TEST');
"generate_script()" accepts the name of the script to generate and will look for a template with the same name and suffix .PL. So in our
example it'll look for t/TEST.PL. The autogenerated script t/TEST will include the contents of t/TEST.PL, and special directives, including
any configuration options passed via "filter_args()" called from Makefile.PL, special fixup code, etc.
