816 | |
817 | Shell variables from the F<config.sh> file (written by Configure) are |
818 | stored in the readonly-variable C<%Config>, indexed by their names. |
819 | |
820 | Values stored in config.sh as 'undef' are returned as undefined |
1fef88e7 |
821 | values. The perl C<exists> function can be used to check if a |
3c81428c |
822 | named variable exists. |
823 | |
3acf89b2 |
824 | For a description of the variables, please have a look at the |
825 | Glossary file, as written in the Porting folder, or use the url: |
826 | http://perl5.git.perl.org/perl.git/blob/HEAD:/Porting/Glossary |

830 | =item myconfig() |
831 | |
832 | Returns a textual summary of the major perl configuration values. |
833 | See also C<-V> in L<perlrun/Switches>. |
834 | |
835 | =item config_sh() |
836 | |
837 | Returns the entire perl configuration information in the form of the |
838 | original config.sh shell variable assignment script. |
839 | |
a48f8c77 |
840 | =item config_re($regex) |
841 | |
842 | Like config_sh() but returns, as a list, only the config entries who's |
843 | names match the $regex. |
844 | |
3c81428c |
845 | =item config_vars(@names) |
846 | |
847 | Prints to STDOUT the values of the named configuration variable. Each is |
848 | printed on a separate line in the form: |
849 | |
850 | name='value'; |
851 | |
852 | Names which are unknown are output as C<name='UNKNOWN';>. |

857 | =head1 EXAMPLE |
858 | |
859 | Here's a more sophisticated example of using %Config: |
860 | |
861 | use Config; |
743c51bc |
862 | use strict; |
863 | |
864 | my %sig_num; |
865 | my @sig_name; |
866 | unless($Config{sig_name} && $Config{sig_num}) { |
867 | die "No sigs?"; |
868 | } else { |
869 | my @names = split ' ', $Config{sig_name}; |
870 | @sig_num{@names} = split ' ', $Config{sig_num}; |
871 | foreach (@names) { |
872 | $sig_name[$sig_num{$_}] ||= $_; |
873 | } |
874 | } |
3c81428c |
875 | |
743c51bc |
876 | print "signal #17 = $sig_name[17]\n"; |
877 | if ($sig_num{ALRM}) { |
878 | print "SIGALRM is $sig_num{ALRM}\n"; |
3c81428c |
879 | } |
880 | |
881 | =head1 WARNING |
882 | |
883 | Because this information is not stored within the perl executable |
884 | itself it is possible (but unlikely) that the information does not |
885 | relate to the actual perl binary which is being used to access it. |
886 | |
887 | The Config module is installed into the architecture and version |
888 | specific library directory ($Config{installarchlib}) and it checks the |
889 | perl version number when loaded. |
890 | |
435ec615 |
891 | The values stored in config.sh may be either single-quoted or |
892 | double-quoted. Double-quoted strings are handy for those cases where you |
893 | need to include escape sequences in the strings. To avoid runtime variable |
894 | interpolation, any C<$> and C<@> characters are replaced by C<\$> and |
895 | C<\@>, respectively. This isn't foolproof, of course, so don't embed C<\$> |
896 | or C<\@> in double-quoted strings unless you're willing to deal with the |
897 | consequences. (The slashes will end up escaped and the C<$> or C<@> will |
898 | trigger variable interpolation) |

900 | =head1 GLOSSARY |
901 | |
902 | Most C<Config> variables are determined by the C<Configure> script |
903 | on platforms supported by it (which is most UNIX platforms). Some |
904 | platforms have custom-made C<Config> variables, and may thus not have |
905 | some of the variables described below, or may have extraneous variables |
906 | specific to that particular port. See the port specific documentation |
907 | in such cases. |
