cpanfile-dump — Dump prerequisites from a cpanfile


# Install typical required and recommended modules
cpan `cpanfile-dump`
# Skip configures phase
cpan `cpanfile-dump --no-configure`
# Also include develop phase and suggests type 
cpan `cpanfile-dump --develop --suggests`
# Include a feature
cpan `cpanfile-dump --with-feature=sqlite`


This script reads prereqs from a cpanfile and dumps a raw list of them to standard output. This is useful for piping these as input to another program that doesn't support reading cpanfile directly, i.e. "cpan" or "cpanp".

By default, it prints configure, build, test and runtime requirements and recommendations. Command line options can be used to modify the default choices.

This script is distributed with Module::CPANfile since version 1.0002.


--configure, --build, --test, --runtime, --develop
Specify the phase to include/exclude. Defaults to include all but "--develop" but you can exclude some phases by specifying the options with "--no-" prefix, like "--no-configure".
--requires, --recommends, --suggests, --conflicts
Specify the type to include/exclude. Defaults to include only "--requires" and "--recommends" but you can exclude some types by specifying the options with "--no-" prefix, like "--no-recommends".

Specifying "--conflicts" will turn off all other types (even if specified on the command line).
--with-feature, --with-all-features, --without-feature
cpanfile-dump --with-feature=sqlite
cpanfile-dump --with-all-features --without-feature=yaml

Specify features to include in the dump. "--with-feature" and "--without-feature" may be used more than once.


Because "cpanm" supports reading cpanfile directly, instead of piping the output of this program, you're recommended to use "cpanm --installdeps ." to install modules from cpanfile.
