=item Programming Examples
This enables the programmer to do operations that combine
perl -MCPAN -e 'CPAN::Shell->install(CPAN::Shell->r)'
# install my favorite programs if necessary:
- for $mod (qw(Net::FTP MD5 Data::Dumper)){
+ for $mod (qw(Net::FTP Digest::MD5 Data::Dumper)){
my $obj = CPAN::Shell->expand('Module',$mod);
$obj->install;
}
print "No VERSION in ", $mod->id, "\n";
}
+ # find out which distribution on CPAN contains a module:
+ print CPAN::Shell->expand("Module","Apache::Constants")->cpan_file
+
+Or if you want to write a cronjob to watch The CPAN, you could list
+all modules that need updating. First a quick and dirty way:
+
+ perl -e 'use CPAN; CPAN::Shell->r;'
+
+If you don't want to get any output in the case that all modules are
+up to date, you can parse the output of above command for the regular
+expression //modules are up to date// and decide to mail the output
+only if it doesn't match. Ick?
+
+If you prefer to do it more in a programmer style in one single
+process, maybe something like this suits you better:
+
+ # list all modules on my disk that have newer versions on CPAN
+ for $mod (CPAN::Shell->expand("Module","/./")){
+ next unless $mod->inst_file;
+ next if $mod->uptodate;
+ printf "Module %s is installed as %s, could be updated to %s from CPAN\n",
+ $mod->id, $mod->inst_version, $mod->cpan_version;
+ }
+
+If that gives you too much output every day, you maybe only want to
+watch for three modules. You can write
+
+ for $mod (CPAN::Shell->expand("Module","/Apache|LWP|CGI/")){
+
+as the first line instead. Or you can combine some of the above
+tricks:
+
+ # watch only for a new mod_perl module
+ $mod = CPAN::Shell->expand("Module","mod_perl");
+ exit if $mod->uptodate;
+ # new mod_perl arrived, let me know all update recommendations
+ CPAN::Shell->r;

defined:

+documentation that comes with the ncftp program. If you are unable to
+go through the firewall with a simple Perl setup, it is very likely
+that you can configure ncftp so that it works for your firewall.

+
+or
+
+ perl -MCPAN -e '$ENV{FTP_PASSIVE} = 1; shell'

+=head2 Configuring lynx or ncftp for going through a firewall
+
+If you can go through your firewall with e.g. lynx, presumably with a
+command such as
+
+ /usr/local/bin/lynx -pscott:tiger
+
+then you would configure CPAN.pm with the command
+
+ o conf lynx "/usr/local/bin/lynx -pscott:tiger"
+
+That's all. Similarly for ncftp or ftp, you would configure something
+like
+
+ o conf ncftp "/usr/bin/ncftp -f /home/scott/ncftplogin.cfg"
+
+Your mileage may vary...
+
+=head1 Cryptographically signed modules
+
+Since release 1.77 CPAN.pm has been able to verify cryptographically
+signed module distributions using Module::Signature. The CPAN modules
+can be signed by their authors, thus giving more security. The simple
+unsigned MD5 checksums that were used before by CPAN protect mainly
+against accidental file corruption.
+
+You will need to have Module::Signature installed, which in turn
+requires that you have at least one of Crypt::OpenPGP module or the
+command-line F<gpg> tool installed.
+
+You will also need to be able to connect over the Internet to the public
+keyservers, like pgp.mit.edu, and their port 11731 (the HKP protocol).
+
+=head1 FAQ
+
+=over 4
+
+=item 1)
+
+I installed a new version of module X but CPAN keeps saying,
+I have the old version installed
+
+Most probably you B<do> have the old version installed. This can
+happen if a module installs itself into a different directory in the
+@INC path than it was previously installed. This is not really a
+CPAN.pm problem, you would have the same problem when installing the
+module manually. The easiest way to prevent this behaviour is to add
+the argument C<UNINST=1> to the C<make install> call, and that is why
+many people add this argument permanently by configuring
+
+ o conf make_install_arg UNINST=1
+
+=item 2)
+
+So why is UNINST=1 not the default?
+
+Because there are people who have their precise expectations about who
+may install where in the @INC path and who uses which @INC array. In
+fine tuned environments C<UNINST=1> can cause damage.
+
+=item 3)
+
+I want to clean up my mess, and install a new perl along with
+all modules I have. How do I go about it?
+
+Run the autobundle command for your old perl and optionally rename the
+resulting bundle file (e.g. Bundle/mybundle.pm), install the new perl
+with the Configure option prefix, e.g.
+
+ ./Configure -Dprefix=/usr/local/perl-5.6.78.9
+
+Install the bundle file you produced in the first step with something like
+
+ cpan> install Bundle::mybundle
+
+and you're done.
+
+=item 4)
+
+When I install bundles or multiple modules with one command
+there is too much output to keep track of.
+
+You may want to configure something like
+
+ o conf make_arg "| tee -ai /root/.cpan/logs/make.out"
+ o conf make_install_arg "| tee -ai /root/.cpan/logs/make_install.out"
+
+so that STDOUT is captured in a file for later inspection.
+
+
+=item 5)
+
+I am not root, how can I install a module in a personal directory?
+
+First of all, you will want to use your own configuration, not the one
+that your root user installed. The following command sequence is a
+possible approach:
+
+ % mkdir -p $HOME/.cpan/CPAN
+ % echo '$CPAN::Config={ };' > $HOME/.cpan/CPAN/MyConfig.pm
+ % cpan
+ [...answer all questions...]
+
+You will most probably like something like this:
+
+ o conf makepl_arg "LIB=~/myperl/lib \
+ INSTALLMAN1DIR=~/myperl/man/man1 \
+ INSTALLMAN3DIR=~/myperl/man/man3"
+
+You can make this setting permanent like all C<o conf> settings with
+C<o conf commit>.
+
+You will have to add ~/myperl/man to the MANPATH environment variable
+and also tell your perl programs to look into ~/myperl/lib, e.g. by
+including
+
+ use lib "$ENV{HOME}/myperl/lib";
+
+or setting the PERL5LIB environment variable.
+
+Another thing you should bear in mind is that the UNINST parameter
+should never be set if you are not root.
+
+=item 6)
+
+How to get a package, unwrap it, and make a change before building it?
+
+ look Sybase::Sybperl
+
+=item 7)
+
+I installed a Bundle and had a couple of fails. When I
+retried, everything resolved nicely. Can this be fixed to work
+on first try?
+
+The reason for this is that CPAN does not know the dependencies of all
+modules when it starts out. To decide about the additional items to
+install, it just uses data found in the generated Makefile. An
+undetected missing piece breaks the process. But it may well be that
+your Bundle installs some prerequisite later than some depending item
+and thus your second try is able to resolve everything. Please note,
+CPAN.pm does not know the dependency tree in advance and cannot sort
+the queue of things to install in a topologically correct order. It
+resolves perfectly well IFF all modules declare the prerequisites
+correctly with the PREREQ_PM attribute to MakeMaker. For bundles which
+fail and you need to install often, it is recommended to sort the Bundle
+definition file manually. It is planned to improve the metadata
+situation for dependencies on CPAN in general, but this will still
+take some time.
+
+=item 8)
+
+In our intranet we have many modules for internal use. How
+can I integrate these modules with CPAN.pm but without uploading
+the modules to CPAN?
+
+Have a look at the CPAN::Site module.
+
+=item 9)
+
+When I run CPAN's shell, I get error msg about line 1 to 4,
+setting meta input/output via the /etc/inputrc file.
+
+Some versions of readline are picky about capitalization in the
+/etc/inputrc file and specifically RedHat 6.2 comes with a
+/etc/inputrc that contains the word C<on> in lowercase. Change the
+occurrences of C<on> to C<On> and the bug should disappear.
+
+=item 10)
+
+Some authors have strange characters in their names.
+
+Internally CPAN.pm uses the UTF-8 charset. If your terminal is
+expecting ISO-8859-1 charset, a converter can be activated by setting
+term_is_latin to a true value in your config file. One way of doing so
+would be
+
+ cpan> ! $CPAN::Config->{term_is_latin}=1
+
+Extended support for converters will be made available as soon as perl
+becomes stable with regard to charset issues.
+
+=item 11)
+
+When an install fails for some reason and then I correct the error
+condition and retry, CPAN.pm refuses to install the module, saying
+C<Already tried without success>.
+
+Use the force pragma like so
+
+ force install Foo::Bar
+
+This does a bit more than really needed because it untars the
+distribution again and runs make and test and only then install.
+
+Or you can use
+
+ look Foo::Bar
+
+and then 'make install' directly in the subshell.
+
+Or you leave the CPAN shell and start it again.
+
+For the really curious, by accessing internals directly, you I<could>
+
+ ! delete CPAN::Shell->expand("Distribution", \
+ CPAN::Shell->expand("Module","Foo::Bar") \
+ ->{RO}{CPAN_FILE})->{install}
+
+but this is neither guaranteed to work in the future nor is it a
+decent command.
