798 | =head1 DESCRIPTION | |
799 | ||
800 | The Config module contains all the information that was available to | |
801 | the C<Configure> program at Perl build time (over 900 values). | |
802 | ||
803 | Shell variables from the F<config.sh> file (written by Configure) are | |
804 | stored in the readonly-variable C<%Config>, indexed by their names. | |
805 | ||
806 | Values stored in config.sh as 'undef' are returned as undefined | |
1fef88e7 | 807 | values. The perl C<exists> function can be used to check if a |
3c81428c | 808 | named variable exists. |
809 | ||
3acf89b2 MB |
810 | For a description of the variables, please have a look at the |
811 | Glossary file, as written in the Porting folder, or use the url: | |
812 | http://perl5.git.perl.org/perl.git/blob/HEAD:/Porting/Glossary | |
813 | ||
3c81428c | 814 | =over 4 |
815 | ||
816 | =item myconfig() | |
817 | ||
818 | Returns a textual summary of the major perl configuration values. | |
819 | See also C<-V> in L<perlrun/Switches>. | |
820 | ||
821 | =item config_sh() | |
822 | ||
823 | Returns the entire perl configuration information in the form of the | |
824 | original config.sh shell variable assignment script. | |
825 | ||
a48f8c77 MS |
826 | =item config_re($regex) |
827 | ||
828 | Like config_sh() but returns, as a list, only the config entries who's | |
829 | names match the $regex. | |
830 | ||
3c81428c | 831 | =item config_vars(@names) |
832 | ||
833 | Prints to STDOUT the values of the named configuration variable. Each is | |
834 | printed on a separate line in the form: | |
835 | ||
836 | name='value'; | |
837 | ||
838 | Names which are unknown are output as C<name='UNKNOWN';>. | |
839 | See also C<-V:name> in L<perlrun/Switches>. | |

843 | =head1 EXAMPLE | |
844 | ||
845 | Here's a more sophisticated example of using %Config: | |
846 | ||
847 | use Config; | |
743c51bc W |
848 | use strict; |
849 | ||
850 | my %sig_num; | |
851 | my @sig_name; | |
852 | unless($Config{sig_name} && $Config{sig_num}) { | |
853 | die "No sigs?"; | |
854 | } else { | |
855 | my @names = split ' ', $Config{sig_name}; | |
856 | @sig_num{@names} = split ' ', $Config{sig_num}; | |
857 | foreach (@names) { | |
858 | $sig_name[$sig_num{$_}] ||= $_; | |
859 | } | |
860 | } | |
3c81428c | 861 | |
743c51bc W |
862 | print "signal #17 = $sig_name[17]\n"; |
863 | if ($sig_num{ALRM}) { | |
864 | print "SIGALRM is $sig_num{ALRM}\n"; | |
3c81428c | 865 | } |
866 | ||
867 | =head1 WARNING | |
868 | ||
869 | Because this information is not stored within the perl executable | |
870 | itself it is possible (but unlikely) that the information does not | |
871 | relate to the actual perl binary which is being used to access it. | |
872 | ||
873 | The Config module is installed into the architecture and version | |
874 | specific library directory ($Config{installarchlib}) and it checks the | |
875 | perl version number when loaded. | |
876 | ||
435ec615 HM |
877 | The values stored in config.sh may be either single-quoted or |
878 | double-quoted. Double-quoted strings are handy for those cases where you | |
879 | need to include escape sequences in the strings. To avoid runtime variable | |
880 | interpolation, any C<$> and C<@> characters are replaced by C<\$> and | |
881 | C<\@>, respectively. This isn't foolproof, of course, so don't embed C<\$> | |
882 | or C<\@> in double-quoted strings unless you're willing to deal with the | |
883 | consequences. (The slashes will end up escaped and the C<$> or C<@> will | |
884 | trigger variable interpolation) | |

886 | =head1 GLOSSARY |
887 | ||
888 | Most C<Config> variables are determined by the C<Configure> script | |
889 | on platforms supported by it (which is most UNIX platforms). Some | |
890 | platforms have custom-made C<Config> variables, and may thus not have | |
891 | some of the variables described below, or may have extraneous variables | |
892 | specific to that particular port. See the port specific documentation | |
893 | in such cases. | |
