NAME ^

CPAN::Mini - create a minimal mirror of CPAN

VERSION ^

version 1.111016

SYNOPSIS ^

(If you're not going to do something weird, you probably want to look at the minicpan command, instead.)

  use CPAN::Mini;

  CPAN::Mini->update_mirror(
    remote => "http://cpan.mirrors.comintern.su",
    local  => "/usr/share/mirrors/cpan",
    log_level => 'debug',
  );

DESCRIPTION ^

CPAN::Mini provides a simple mechanism to build and update a minimal mirror of the CPAN on your local disk. It contains only those files needed to install the newest version of every distribution. Those files are:

METHODS ^

update_mirror

  CPAN::Mini->update_mirror(
    remote => "http://cpan.mirrors.comintern.su",
    local  => "/usr/share/mirrors/cpan",
    force  => 0,
    log_level => 'debug',
  );

This is the only method that need be called from outside this module. It will update the local mirror with the files from the remote mirror.

If called as a class method, update_mirror creates an ephemeral CPAN::Mini object on which other methods are called. That object is used to store mirror location and state.

This method returns the number of files updated.

The following options are recognized:

new

  my $minicpan = CPAN::Mini->new;

This method constructs a new CPAN::Mini object. Its parameters are described above, under update_mirror.

mirror_indices

  $minicpan->mirror_indices;

This method updates the index files from the CPAN.

mirror_file

  $minicpan->mirror_file($path, $skip_if_present)

This method will mirror the given file from the remote to the local mirror, overwriting any existing file unless $skip_if_present is true.

file_allowed

  next unless $minicpan->file_allowed($filename);

This method returns true if the given file is allowed to exist in the local mirror, even if it isn't one of the required mirror files.

By default, only dot-files are allowed. If the exact_mirror option is true, all files are allowed.

clean_unmirrored

  $minicpan->clean_unmirrored;

This method looks through the local mirror's files. If it finds a file that neither belongs in the mirror nor is allowed (see the file_allowed method), clean_file is called on the file.

If you set ignore_source_control to a true value, then this doesn't clean up files that belong to source control systems. Currently this ignores:

        .cvs .cvsignore
        .svn .svnignore
        .git .gitignore

Send patches for other source control files that you would like to have added.

clean_file

  $minicpan->clean_file($filename);

This method, called by clean_unmirrored, deletes the named file. It returns true if the file is successfully unlinked. Otherwise, it returns false.

log_warn

log

log_debug

  $minicpan->log($message);

This will log (print) the given message unless the log level is too low.

log, which logs at the info level, may also be called as trace for backward compatibility reasons.

read_config

  my %config = CPAN::Mini->read_config(\%options);

This routine returns a set of arguments that can be passed to CPAN::Mini's new or update_mirror methods. It will look for a file called .minicpanrc in the user's home directory as determined by File::HomeDir.

config_file

  my $config_file = CPAN::Mini->config_file( { options } );

This routine returns the config file name. It first looks at for the config_file setting, then the CPAN_MINI_CONFIG environment variable, then the default ~/.minicpanrc, and finally the CPAN/Mini/minicpan.conf. It uses the first defined value it finds. If the filename it selects does not exist, it returns false.

OPTIONS is an optional hash reference of the CPAN::Mini config hash.

remote_from

  my $remote = CPAN::Mini->remote_from( $remote_from, $orig_remote, $quiet );

This routine take an string argument and turn it into a method call to handle to retrieve the a cpan mirror url from a source. Currently supported methods:

    cpan     - fetch the first mirror from your CPAN.pm config
    cpanplus - fetch the first mirror from your CPANPLUS.pm config

remote_from_cpan

  my $remote = CPAN::Mini->remote_from_cpan;

This routine loads your CPAN.pm config and returns the first mirror in mirror list. You can set this as your default by setting remote_from:cpan in your .minicpanrc file.

remote_from_cpanplus

  my $remote = CPAN::Mini->remote_from_cpanplus;

This routine loads your CPANPLUS.pm config and returns the first mirror in mirror list. You can set this as your default by setting remote_from:cpanplus in your .minicpanrc file.
