cpandeps - show a module on the CPAN's dependency tree.
This program is a simple wrapper around CPAN::FindDependencies.
cpandeps CPAN::FindDependencies cpandeps CPAN::FindDependencies perl 5.8.8 cachedir ../foo/bar cpandeps --showmoduleversions CPAN::FindDependencies
Given a module name, this program will show you the module's dependency tree. It takes exactly the same arguments as the
finddeps function of CPAN::FindDependencies, with the exception that
nowarnings is turned *on* by default.
Warnings about modules where we can't find their META.yml or Makefile.PL, and so can't divine their pre-requisites, will be suppressed;
Failure to get a module's dependencies will be a fatal error instead of merely emitting a warning;
Use this version of perl to figure out what's in core. If not specified, it defaults to 5.005. Three part version numbers (eg 5.8.8) are supported but discouraged.
The location of CPAN.pm's
02packages.details.txt.gzfile as a local filename, with either a relative or an absolute path. If not specified, it is fetched from a CPAN mirror instead. The file is fetched just once.
A directory to use for caching. It defaults to no caching. Even if caching is turned on, this is only for META.yml or Makefile.PL files. 02packages is not cached - if you want to read that from a local disk, see the
Cuts off the dependency tree at the specified depth. Your specified module is at depth 0, your dependencies at depth 1, their dependencies at depth 2, and so on.
If set to true, then for any module that doesn't have a META.yml, try to use its Makefile.PL as well. Note that this involves downloading code from the Internet and running it. This obviously opens you up to all kinds of bad juju, hence why it is disabled by default.
Adds recommended modules to the list of dependencies, if set to a true value.
It also takes the following extra parameter, which must be the first one:
It shows the module name, its distribution, and if any warnings were raised (such as if a module's dependencies couldn't be fetched) this is indicated with an asterisk before the module's name.
This script has not been thoroughly tested.
I welcome feedback about my code, including constructive criticism. Bug reports should be made using http://rt.cpan.org/ or by email.
