879 | =head1 RECIPES / SPECIFIC MODULES |
|
|
880 | |
|
|
881 | This section contains some common(?) recipes and information about |
|
|
882 | problems with some common modules or perl constructs that require extra |
|
|
883 | files to be included. |
|
|
884 | |
|
|

887 | =over 4 |
|
|
888 | |
|
|
889 | =item utf8 |
|
|
890 | |
|
|
891 | Some functionality in the utf8 module, such as swash handling (used |
|
|
892 | for unicode character ranges in regexes) is implemented in the |
|
|
893 | C<"utf8_heavy.pl"> library: |
|
|
894 | |
|
|
895 | -M'"utf8_heavy.pl"' |
|
|
896 | |
|
|
897 | Many Unicode properties in turn are defined in separate modules, |
|
|
898 | such as C<"unicore/Heavy.pl"> and more specific data tables such as |
|
|
899 | C<"unicore/To/Digit.pl"> or C<"unicore/lib/Perl/Word.pl">. These tables |
|
|
900 | are big (7MB uncompressed, although F<staticperl> contains special |
|
|
901 | handling for those files), so including them on demand by your application |
|
|
902 | only might pay off. |
|
|
903 | |
|
|
904 | To simply include the whole unicode database, use: |
|
|
905 | |
|
|
906 | --incglob '/unicore/*.pl' |
|
|
907 | |
|
|
908 | =item AnyEvent |
|
|
909 | |
|
|
910 | AnyEvent needs a backend implementation that it will load in a delayed |
|
|
911 | fashion. The L<AnyEvent::Impl::Perl> backend is the default choice |
|
|
912 | for AnyEvent if it can't find anything else, and is usually a safe |
|
|
913 | fallback. If you plan to use e.g. L<EV> (L<POE>...), then you need to |
|
|
914 | include the L<AnyEvent::Impl::EV> (L<AnyEvent::Impl::POE>...) backend as |
|
|
915 | well. |
|
|
916 | |
|
|
917 | If you want to handle IRIs or IDNs (L<AnyEvent::Util> punycode and idn |
|
|
918 | functions), you also need to include C<"AnyEvent/Util/idna.pl"> and |
|
|
919 | C<"AnyEvent/Util/uts46data.pl">. |
|
|
920 | |
|
|
921 | =item Carp |
|
|
922 | |
|
|
923 | Carp had (in older versions of perl) a dependency on L<Carp::Heavy>. As of |
|
|
924 | perl 5.12.2 (maybe earlier), this dependency no longer exists. |
|
|
925 | |
|
|
926 | =item Config |
|
|
927 | |
|
|
928 | The F<perl -V> switch (as well as many modules) needs L<Config>, which in |
|
|
929 | turn might need L<"Config_heavy.pl">. Including the latter gives you |
|
|
930 | both. |
|
|
931 | |
|
|
932 | =item Term::ReadLine::Perl |
|
|
933 | |
|
|
934 | Also needs L<Term::ReadLine::readline>. |
|
|
935 | |
|
|
936 | =item URI |
|
|
937 | |
|
|
938 | URI implements schemes as separate modules - the generic URL scheme is |
|
|
939 | implemented in L<URI::_generic>, HTTP is implemented in L<URI::http>. If |
|
|
940 | you need to use any of these schemes, you should include these manually. |

|
|
955 | =item Getting rid of netdb function |
|
|
956 | |
|
|
957 | The perl core has lots of netdb functions (C<getnetbyname>, C<getgrent> |
|
|
958 | and so on) that few applications use. You can avoid compiling them in by |
|
|
959 | putting the following fragment into a C<preconfigure> hook: |
|
|
960 | |
|
|
961 | preconfigure() { |
|
|
962 | for sym in \ |
|
|
963 | d_getgrnam_r d_endgrent d_endgrent_r d_endhent \ |

|
|
971 | d_getpent d_getpbyname d_getpbynumber d_getprotobyname_r \ |
|
|
972 | d_getprotobynumber_r d_getprotoent_r d_getpwent \ |

|

|
|
977 | do |
|
|
978 | PERL_CONFIGURE="$PERL_CONFIGURE -U$sym" |
|
|
979 | done |
|
|
980 | } |
|
|
981 | |
|
|
982 | This mostly gains space when linking staticaly, as the functions will |
|
|
983 | liekly not be linked in. The gain for dynamically-linked binaries is |
|
|
984 | smaller. |
|
|
985 | |
|
|
986 | Also, this leaves C<gethostbyname> in - not only is it actually used |
|
|
987 | often, the L<Socket> module also exposes it, so leaving it out usually |
|
|
988 | gains little. Why Socket exposes a C function that is in the core already |
|
|
989 | is anybody's guess. |
