Cyrus::IMAP::IMSP - Perl module for Cyrus IMSP user options



  use Cyrus::IMAP::IMSP;

  my $client = Cyrus::IMAP::IMSP->new(imsphost[, $port[, $flags]]);
  $rc = $client->set(mailreader.window.size, 200x300);
  %options = $client->get(mailreader.*)
  $rc = $client->unset(mailreader.window.size);


This module is a Perl interface to the Cyrus IMSP functions that relate to user options (preferences). Only three IMSP operations are implemented: set, unset, and get.


new($server[, $port[, $flags]]) Instantiates a <B>Cyrus::IMAP::IMSPB> object. This is in fact a Cyrus::IMAP object with a few additional methods, so all Cyrus::IMAP methods are available if needed. (In particular, you will always want to use the authenticate method.)
error Return the last error that occurred, or undef if the last operation was successful. This is in some cases (such as get) the only way to distinguish between a successful return of an empty list and an error return.

Calling error does not reset the error state, so it is legal to write:

    %options = $client->get($option);
    print STDERR "Error: ", $client->error if $client->error;

set($option, $value) Sets the option named by $option to the value in $value.

There are no restrictions or quoting rules needed to protect special characters in the value argument. (The Cyrus::IMAP layer will take care those details by adding double quotes or a literal introducer.)

If successful, returns 1. Otherwise, returns undef and makes an error message available through the error function.

unset($option) Removes the option named by $option. The option is completely removed from the user’s name space but will revert to a site-wide default if one has been set. Note that this is different from assigning an option the null value with set($option, ’’).

If you try to unset an option that does not exist, an error is returned saying that the option was already unset.

If successful, returns 1. Otherwise, returns undef and makes an error message available through the error function.

get($option_pattern) Get takes either an option name or a pattern of names to fetch. The pattern can contain either * or % wildcards anywhere in the string. The usual IMAP wildcard semantics apply.

The return value is a hash of options with each key being an option name and each value being the option’s value string. If an empty hash is returned, it’s either because there were no matching options or because some error happened. Check the error function to see which was the case.

The IMSP protocol also returns an access flag of [READ-WRITE] or [READ-ONLY] but that information is discarded by this function. A more complicated function that returns both the value and the access flag could be added later if needed.
