897 | # | |
898 | # =head1 SYNOPSIS | |
899 | # | |
900 | # use Config; | |
901 | # if ($Config{usethreads}) { | |
902 | # print "has thread support\n" | |
903 | # } | |
904 | # | |
905 | # use Config qw(myconfig config_sh config_vars config_re); | |
906 | # | |
907 | # print myconfig(); | |
908 | # | |
909 | # print config_sh(); | |

911 | # print config_re(); | |
912 | # | |
913 | # config_vars(qw(osname archname)); | |
914 | # | |
915 | # | |
916 | # =head1 DESCRIPTION | |
917 | # | |
918 | # The Config module contains all the information that was available to | |
919 | # the F<Configure> program at Perl build time (over 900 values). | |
920 | # | |
921 | # Shell variables from the F<config.sh> file (written by Configure) are | |
922 | # stored in the readonly-variable C<%Config>, indexed by their names. | |
923 | # | |
924 | # Values stored in config.sh as 'undef' are returned as undefined | |
925 | # values. The perl C<exists> function can be used to check if a | |
926 | # named variable exists. | |
927 | # | |
928 | # For a description of the variables, please have a look at the | |
929 | # Glossary file, as written in the Porting folder, or use the url: | |
930 | # https://github.com/Perl/perl5/blob/blead/Porting/Glossary | |
931 | # | |
932 | # =over 4 | |
933 | # | |
934 | # =item myconfig() | |
935 | # | |
936 | # Returns a textual summary of the major perl configuration values. | |
937 | # See also C<-V> in L<perlrun/Command Switches>. | |
938 | # | |
939 | # =item config_sh() | |
940 | # | |
941 | # Returns the entire perl configuration information in the form of the | |
942 | # original config.sh shell variable assignment script. | |
943 | # | |
944 | # =item config_re($regex) | |
945 | # | |
946 | # Like config_sh() but returns, as a list, only the config entries who's | |
947 | # names match the $regex. | |
948 | # | |
949 | # =item config_vars(@names) | |
950 | # | |
951 | # Prints to STDOUT the values of the named configuration variable. Each is | |
952 | # printed on a separate line in the form: | |
953 | # | |
954 | # name='value'; | |
955 | # | |
956 | # Names which are unknown are output as C<name='UNKNOWN';>. | |
957 | # See also C<-V:name> in L<perlrun/Command Switches>. | |
958 | # | |
959 | # =item bincompat_options() | |
960 | # | |
961 | # Returns a list of C pre-processor options used when compiling this F<perl> | |
962 | # binary, which affect its binary compatibility with extensions. | |
963 | # C<bincompat_options()> and C<non_bincompat_options()> are shown together in | |
964 | # the output of C<perl -V> as I<Compile-time options>. | |
965 | # | |
966 | # =item non_bincompat_options() | |
967 | # | |
968 | # Returns a list of C pre-processor options used when compiling this F<perl> | |
969 | # binary, which do not affect binary compatibility with extensions. | |
970 | # | |
971 | # =item compile_date() | |
972 | # | |
973 | # Returns the compile date (as a string), equivalent to what is shown by | |
974 | # C<perl -V> | |
975 | # | |
976 | # =item local_patches() | |
977 | # | |
978 | # Returns a list of the names of locally applied patches, equivalent to what | |
979 | # is shown by C<perl -V>. | |
980 | # | |
981 | # =item header_files() | |
982 | # | |
983 | # Returns a list of the header files that should be used as dependencies for | |
984 | # XS code, for this version of Perl on this platform. | |
985 | # | |
986 | # =back | |
987 | # | |
988 | # =head1 EXAMPLE | |
989 | # | |
990 | # Here's a more sophisticated example of using %Config: | |
991 | # | |
992 | # use Config; | |
993 | # use strict; | |
994 | # | |
995 | # my %sig_num; | |
996 | # my @sig_name; | |
997 | # unless($Config{sig_name} && $Config{sig_num}) { | |
998 | # die "No sigs?"; | |
999 | # } else { | |
1000 | # my @names = split ' ', $Config{sig_name}; | |
1001 | # @sig_num{@names} = split ' ', $Config{sig_num}; | |
1002 | # foreach (@names) { | |
1003 | # $sig_name[$sig_num{$_}] ||= $_; | |
1004 | # } | |
1005 | # } | |
1006 | # | |
1007 | # print "signal #17 = $sig_name[17]\n"; | |
1008 | # if ($sig_num{ALRM}) { | |
1009 | # print "SIGALRM is $sig_num{ALRM}\n"; | |
1010 | # } | |
1011 | # | |
1012 | # =head1 WARNING | |
1013 | # | |
1014 | # Because this information is not stored within the perl executable | |
1015 | # itself it is possible (but unlikely) that the information does not | |
1016 | # relate to the actual perl binary which is being used to access it. | |
1017 | # | |
1018 | # The Config module is installed into the architecture and version | |
1019 | # specific library directory ($Config{installarchlib}) and it checks the | |
1020 | # perl version number when loaded. | |
1021 | # | |
1022 | # The values stored in config.sh may be either single-quoted or | |
1023 | # double-quoted. Double-quoted strings are handy for those cases where you | |
1024 | # need to include escape sequences in the strings. To avoid runtime variable | |
1025 | # interpolation, any C<$> and C<@> characters are replaced by C<\$> and | |
1026 | # C<\@>, respectively. This isn't foolproof, of course, so don't embed C<\$> | |
1027 | # or C<\@> in double-quoted strings unless you're willing to deal with the | |
1028 | # consequences. (The slashes will end up escaped and the C<$> or C<@> will | |
1029 | # trigger variable interpolation) | |
1030 | # | |
1031 | # =head1 GLOSSARY | |
1032 | # | |
1033 | # Most C<Config> variables are determined by the C<Configure> script | |
1034 | # on platforms supported by it (which is most UNIX platforms). Some | |
1035 | # platforms have custom-made C<Config> variables, and may thus not have | |
1036 | # some of the variables described below, or may have extraneous variables | |
1037 | # specific to that particular port. See the port specific documentation | |
1038 | # in such cases. | |
