- =head1 NAME
-
- Config - access Perl configuration information
-
- =head1 SYNOPSIS
-
- use Config;
- if ($Config{'cc'} =~ /gcc/) {
- print "built by gcc\n";
- }
-
- use Config qw(myconfig config_sh config_vars);
-
- print myconfig();
-
- print config_sh();
-
- config_vars(qw(osname archname));
-
-
- =head1 DESCRIPTION
-
- The Config module contains all the information that was available to
- the C<Configure> program at Perl build time (over 900 values).
-
- Shell variables from the F<config.sh> file (written by Configure) are
- stored in the readonly-variable C<%Config>, indexed by their names.
-
- Values stored in config.sh as 'undef' are returned as undefined
- values. The perl C<exists> function can be used to check if a
- named variable exists.
-
- =over 4
-
- =item myconfig()
-
- Returns a textual summary of the major perl configuration values.
- See also C<-V> in L<perlrun/Switches>.
-
- =item config_sh()
-
- Returns the entire perl configuration information in the form of the
- original config.sh shell variable assignment script.
-
- =item config_vars(@names)
-
- Prints to STDOUT the values of the named configuration variable. Each is
- printed on a separate line in the form:
-
- name='value';
-
- Names which are unknown are output as C<name='UNKNOWN';>.
- See also C<-V:name> in L<perlrun/Switches>.
-
- =back
-
- =head1 EXAMPLE
-
- Here's a more sophisticated example of using %Config:
-
- use Config;
- use strict;
-
- my %sig_num;
- my @sig_name;
- unless($Config{sig_name} && $Config{sig_num}) {
- die "No sigs?";
- } else {
- my @names = split ' ', $Config{sig_name};
- @sig_num{@names} = split ' ', $Config{sig_num};
- foreach (@names) {
- $sig_name[$sig_num{$_}] ||= $_;
- }
- }
-
- print "signal #17 = $sig_name[17]\n";
- if ($sig_num{ALRM}) {
- print "SIGALRM is $sig_num{ALRM}\n";
- }
-
- =head1 WARNING
-
- Because this information is not stored within the perl executable
- itself it is possible (but unlikely) that the information does not
- relate to the actual perl binary which is being used to access it.
-
- The Config module is installed into the architecture and version
- specific library directory ($Config{installarchlib}) and it checks the
- perl version number when loaded.
-
- =head1 NOTE
-
- This module contains a good example of how to use tie to implement a
- cache and an example of how to make a tied variable readonly to those
- outside of it.
