At the moment it uses \s-1CPAN\s0.pm to do the work, but it is not a one-shot command runner for \s-1CPAN\s0.pm. .SS "Options" .IX Subsection "Options" .IP "\-a" 4 .IX Item "-a" Creates a \s-1CPAN\s0.pm autobundle with CPAN::Shell\->autobundle. .IP "\-A module [ module ... ]" 4 .IX Item "-A module [ module ... ]" Shows the primary maintainers for the specified modules. .IP "\-c module" 4 .IX Item "-c module" Runs a `make clean` in the specified module's directories. .IP "\-C module [ module ... ]" 4 .IX Item "-C module [ module ... ]" Show the \fIChanges\fR files for the specified modules .IP "\-D module [ module ... ]" 4 .IX Item "-D module [ module ... ]" Show the module details. This prints one line for each out-of-date module (meaning, modules locally installed but have newer versions on \s-1CPAN\s0). Each line has three columns: module name, local version, and \s-1CPAN\s0 version. .IP "\-f" 4 .IX Item "-f" Force the specified action, when it normally would have failed. Use this to install a module even if its tests fail. When you use this option, \&\-i is not optional for installing a module when you need to force it: .Sp .Vb 1 \& % cpan \-f \-i Module::Foo .Ve .IP "\-F" 4 .IX Item "-F" Turn off \s-1CPAN\s0.pm's attempts to lock anything. You should be careful with this since you might end up with multiple scripts trying to muck in the same directory. This isn't so much of a concern if you're loading a special config with \f(CW\*(C`\-j\*(C'\fR, and that config sets up its own work directories. .IP "\-g module [ module ... ]" 4 .IX Item "-g module [ module ... ]" Downloads to the current directory the latest distribution of the module. .IP "\-G module [ module ... ]" 4 .IX Item "-G module [ module ... ]" \&\s-1UNIMPLEMENTED\s0 .Sp Download to the current directory the latest distribution of the modules, unpack each distribution, and create a git repository for each distribution. .Sp If you want this feature, check out Yanick Champoux's \f(CW\*(C`Git::CPAN::Patch\*(C'\fR distribution. .IP "\-h" 4 .IX Item "-h" Print a help message and exit. When you specify \f(CW\*(C`\-h\*(C'\fR, it ignores all of the other options and arguments. .IP "\-i" 4 .IX Item "-i" Install the specified modules. .IP "\-j Config.pm" 4 .IX Item "-j Config.pm" Load the file that has the \s-1CPAN\s0 configuration data. This should have the same format as the standard \fICPAN/Config.pm\fR file, which defines \&\f(CW$CPAN::Config\fR as an anonymous hash. .IP "\-J" 4 .IX Item "-J" Dump the configuration in the same format that \s-1CPAN\s0.pm uses. This is useful for checking the configuration as well as using the dump as a starting point for a new, custom configuration. .IP "\-L author [ author ... ]" 4 .IX Item "-L author [ author ... ]" List the modules by the specified authors. .IP "\-m" 4 .IX Item "-m" Make the specified modules. .IP "\-O" 4 .IX Item "-O" Show the out-of-date modules. .IP "\-t" 4 .IX Item "-t" Run a `make test` on the specified modules. .IP "\-r" 4 .IX Item "-r" Recompiles dynamically loaded modules with CPAN::Shell\->recompile. .IP "\-v" 4 .IX Item "-v" Print the script version and \s-1CPAN\s0.pm version then exit. .SS "Examples" .IX Subsection "Examples" .Vb 2 \& # print a help message \& cpan \-h \& \& # print the version numbers \& cpan \-v \& \& # create an autobundle \& cpan \-a \& \& # recompile modules \& cpan \-r \& \& # install modules ( sole \-i is optional ) \& cpan \-i Netscape::Booksmarks Business::ISBN \& \& # force install modules ( must use \-i ) \& cpan \-fi CGI::Minimal URI .Ve .SH "EXIT VALUES" .IX Header "EXIT VALUES" The script exits with zero if it thinks that everything worked, or a positive number if it thinks that something failed. Note, however, that in some cases it has to divine a failure by the output of things it does not control. For now, the exit codes are vague: .PP .Vb 1 \& 1 An unknown error \& \& 2 The was an external problem \& \& 4 There was an internal problem with the script \& \& 8 A module failed to install .Ve .SH "TO DO" .IX Header "TO DO" * one shot configuration values from the command line .SH "BUGS" .IX Header "BUGS" * none noted .SH "SEE ALSO" .IX Header "SEE ALSO" Most behaviour, including environment variables and configuration, comes directly from \s-1CPAN\s0.pm. .SH "SOURCE AVAILABILITY" .IX Header "SOURCE AVAILABILITY" This code is in Github: .PP .Vb 1 \& git://github.com/briandfoy/cpan_script.git .Ve .SH "CREDITS" .IX Header "CREDITS" Japheth Cleaver added the bits to allow a forced install (\-f). .PP Jim Brandt suggest and provided the initial implementation for the up-to-date and Changes features. .PP Adam Kennedy pointed out that \fIexit()\fR causes problems on Windows where this script ends up with a .bat extension .SH "AUTHOR" .IX Header "AUTHOR" brian d foy, \f(CW\*(C`<bdfoy@cpan.org>\*(C'\fR .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright (c) 2001\-2009, brian d foy, All Rights Reserved. .PP You may redistribute this under the same terms as Perl itself.
