o type [option] [value]

• Sets and queries options. Takes the following arguments:
  • type
  • Type of options to set or query. The possible values are:
    • debug
    • Debugging options. Prints CPAN module options for debugging the package.
    • conf
    • Configuration options. Lists or sets values for CPAN module configuration variables kept in the hash %CPAN::Config. Here are the configuration variables from %CPAN::Config:

      Variable	Content
      build_cache	Size of cache for directories to build modules
      build_dir	Locally accessible directory to build modules
      index_expire	Number of days before refetching index files
      cpan_home	Local directory reserved for this package
      gzip	Location of external program gzip
      inactivity_timeout	Breaks an interactive Makefile.PL after inactivity_timeout seconds of inactivity (set to 0 to never break)
      inhibit_startup_message	If true, does not print startup message
      keep_source	If set, keeps source in local directory
      keep_source_where	Where to keep source
      make	Location of external make program
      make_arg	Arguments to always pass to make
      make_install_arg	Same as make_arg for make install
      makepl_arg	Arguments to always pass to perl Makefile.PL
      pager	Location of external more program (or other pager)
      tar	Location of external tar program
      unzip	Location of external unzip program
      urllist	Arrayref to nearby CPAN sites (or equivalent locations such as tutorial)

  • option
  • The CPAN module configuration option or options; used with conf. Can be one or more scalar or list options from the table above.
  • value
  • Value to be set for a configuration option.

    The possibilities for o conf are:

    • o conf scalaropt
    • Prints current value of scalar option
    • o conf scalaropt value
    • Sets scalar option to value
    • o conf listopt
    • Prints current value of list option in MakeMaker format
    • o conf listopt [shift|pop]
    • Shifts or pops the array in listopt variable
    • o conf listopt [unshift|push|splice] list
    • Works like the corresponding Perl functions to modify the array in listopt based on list
