3c81428c | 823 | Config - access Perl configuration information |
824 | ||
825 | =head1 SYNOPSIS | |
826 | ||
827 | use Config; | |
63f18be6 NC |
828 | if ($Config{usethreads}) { |
829 | print "has thread support\n" | |
3c81428c | 830 | } |
831 | ||
a48f8c77 | 832 | use Config qw(myconfig config_sh config_vars config_re); |
3c81428c | 833 | |
834 | print myconfig(); | |
835 | ||
836 | print config_sh(); | |
837 | ||
a48f8c77 MS |
838 | print config_re(); |
839 | ||
3c81428c | 840 | config_vars(qw(osname archname)); |
841 | ||
842 | ||
843 | =head1 DESCRIPTION | |
844 | ||
845 | The Config module contains all the information that was available to | |
846 | the C<Configure> program at Perl build time (over 900 values). | |
847 | ||
848 | Shell variables from the F<config.sh> file (written by Configure) are | |
849 | stored in the readonly-variable C<%Config>, indexed by their names. | |
850 | ||
851 | Values stored in config.sh as 'undef' are returned as undefined | |
1fef88e7 | 852 | values. The perl C<exists> function can be used to check if a |
3c81428c | 853 | named variable exists. |
854 | ||
3acf89b2 MB |
855 | For a description of the variables, please have a look at the |
856 | Glossary file, as written in the Porting folder, or use the url: | |
857 | http://perl5.git.perl.org/perl.git/blob/HEAD:/Porting/Glossary | |
858 | ||
3c81428c | 859 | =over 4 |
860 | ||
861 | =item myconfig() | |
862 | ||
863 | Returns a textual summary of the major perl configuration values. | |
2788353a | 864 | See also C<-V> in L<perlrun/Command Switches>. |
3c81428c | 865 | |
866 | =item config_sh() | |
867 | ||
868 | Returns the entire perl configuration information in the form of the | |
869 | original config.sh shell variable assignment script. | |
870 | ||
a48f8c77 MS |
871 | =item config_re($regex) |
872 | ||
873 | Like config_sh() but returns, as a list, only the config entries who's | |
874 | names match the $regex. | |
875 | ||
3c81428c | 876 | =item config_vars(@names) |
877 | ||
878 | Prints to STDOUT the values of the named configuration variable. Each is | |
879 | printed on a separate line in the form: | |
880 | ||
881 | name='value'; | |
882 | ||
883 | Names which are unknown are output as C<name='UNKNOWN';>. | |
2788353a | 884 | See also C<-V:name> in L<perlrun/Command Switches>. |

886 | =item bincompat_options() |
887 | ||
888 | Returns a list of C pre-processor options used when compiling this F<perl> | |
889 | binary, which affect its binary compatibility with extensions. | |
890 | C<bincompat_options()> and C<non_bincompat_options()> are shown together in | |
891 | the output of C<perl -V> as I<Compile-time options>. | |
892 | ||
893 | =item non_bincompat_options() | |
894 | ||
895 | Returns a list of C pre-processor options used when compiling this F<perl> | |
896 | binary, which do not affect binary compatibility with extensions. | |
897 | ||
898 | =item compile_date() | |
899 | ||
900 | Returns the compile date (as a string), equivalent to what is shown by | |
901 | C<perl -V> | |
902 | ||
903 | =item local_patches() | |
904 | ||
905 | Returns a list of the names of locally applied patches, equivalent to what | |
906 | is shown by C<perl -V>. | |
907 | ||
1f0fc1c9 NC |
908 | =item header_files() |
909 | ||
910 | Returns a list of the header files that should be used as dependencies for | |
911 | XS code, for this version of Perl on this platform. | |

915 | =head1 EXAMPLE | |
916 | ||
917 | Here's a more sophisticated example of using %Config: | |
918 | ||
919 | use Config; | |
743c51bc W |
920 | use strict; |
921 | ||
922 | my %sig_num; | |
923 | my @sig_name; | |
924 | unless($Config{sig_name} && $Config{sig_num}) { | |
925 | die "No sigs?"; | |
926 | } else { | |
927 | my @names = split ' ', $Config{sig_name}; | |
928 | @sig_num{@names} = split ' ', $Config{sig_num}; | |
929 | foreach (@names) { | |
930 | $sig_name[$sig_num{$_}] ||= $_; | |
931 | } | |
932 | } | |
3c81428c | 933 | |
743c51bc W |
934 | print "signal #17 = $sig_name[17]\n"; |
935 | if ($sig_num{ALRM}) { | |
936 | print "SIGALRM is $sig_num{ALRM}\n"; | |
3c81428c | 937 | } |
938 | ||
939 | =head1 WARNING | |
940 | ||
941 | Because this information is not stored within the perl executable | |
942 | itself it is possible (but unlikely) that the information does not | |
943 | relate to the actual perl binary which is being used to access it. | |
944 | ||
945 | The Config module is installed into the architecture and version | |
946 | specific library directory ($Config{installarchlib}) and it checks the | |
947 | perl version number when loaded. | |
948 | ||
435ec615 HM |
949 | The values stored in config.sh may be either single-quoted or |
950 | double-quoted. Double-quoted strings are handy for those cases where you | |
951 | need to include escape sequences in the strings. To avoid runtime variable | |
952 | interpolation, any C<$> and C<@> characters are replaced by C<\$> and | |
953 | C<\@>, respectively. This isn't foolproof, of course, so don't embed C<\$> | |
954 | or C<\@> in double-quoted strings unless you're willing to deal with the | |
955 | consequences. (The slashes will end up escaped and the C<$> or C<@> will | |
956 | trigger variable interpolation) | |
957 | ||
ebc74a4b GS |
958 | =head1 GLOSSARY |
959 | ||
960 | Most C<Config> variables are determined by the C<Configure> script | |
961 | on platforms supported by it (which is most UNIX platforms). Some | |
962 | platforms have custom-made C<Config> variables, and may thus not have | |
963 | some of the variables described below, or may have extraneous variables | |
964 | specific to that particular port. See the port specific documentation | |
965 | in such cases. | |
