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 Cyrus::IMAP::IMSP 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.
