rcheck is a tool that will allow you to check the status of one or more accounts on one or more RealizationEngines. rcheck is written in Perl, requires LWP::Simple and Digest::MD5 and Tk.

rcheck is intended to be a demonstration for creating clients that can check for and report new messages.

The status for an account can be requested by the following URL:

http://www.your_re.com/cgi-bin/re_status.cgi?status=username

this will return the results in the form:

total_messages:todays_messages:new_messages

Example: 100:10:2

The results are XORed against the MD5 digest (hex) of the users password before being sent so that the results are "lightly" encrypted. The results are trimmed to the length of the output only.

After receiving the encrypted result string from the server, take the MD5 digest (hex) of the users password, trim it to the same length as the status string and XOR the two against each other. This will give the plaintext of the status message.

rcheck only reports new messages since last session, and the other two numbers are tossed in the trash.

rcheck stores a file called .rcheck2 in the local directory with account information (passwords encrypted).

YAPE::Regex::Element contains sub-classes for YAPE::Regex elements.

SYNOPSIS

use YAPE::Regex MyExt::Mod;
# this sets up inheritence in MyExt::Mod
# see YAPE::Regex documentation

YAPE MODULES

The YAPE hierarchy of modules is an attempt at a unified means of parsing and extracting content. It attempts to maintain a generic interface, to promote simplicity and reusability. The API is powerful, yet simple. The modules do tokenization (which can be intercepted) and build trees, so that extraction of specific nodes is doable.

Methods for YAPE::Regex::Element

This class contains fallback methods for the other classes.
my $str = $obj->text;
Returns a string representation of the content of the regex node itself, not any nodes contained in it. This is undef for non-text nodes.
my $str = $obj->string;
Returns a string representation of the regex node itself, not any nodes contained in it.
my $str = $obj->fullstring;
Returns a string representation of the regex node, including any nodes contained in it.
my $quant = $obj->quant;
Returns a string with the quantity, and a ? if the node is non-greedy. The quantity is one of *, +, ?, {M,N}, or an empty string.
my $ng = $obj->ngreed;
Returns a ? if the node is non-greedy, and an empty string otherwise.

Methods for YAPE::Regex::anchor

This class represents anchors. Objects have the following methods:
my $anchor = YAPE::Regex::anchor->new($type,$q,$ng);
Creates a YAPE::Regex::anchor object. Takes three arguments: the anchor (^, A, $, Z, z, B, b, or G), the quantity, and the non-greedy flag. The quantity should be an empty string.
my $anc = YAPE::Regex::anchor->new(A, , ?);
# /A?/
my $type = $anchor->type;
Returns the string anchor.
Methods for YAPE::Regex::macro
This class represents character-class macros. Objects have the following methods:
my $macro = YAPE::Regex::macro->new($type,$q,$ng);
Creates a YAPE::Regex::macro object. Takes three arguments: the macro (w, W, d, D, s, or S), the quantity, and the non-greedy flag.
my $macro = YAPE::Regex::macro->new(s, {3,5});
# /s{3,5}/
my $text = $macro->text;
Returns the macro.
print $macro->text; # s
my $type = $macro->type;
Returns the string macro.

Methods for YAPE::Regex::oct

This class represents octal escapes. Objects have the following methods:
my $oct = YAPE::Regex::oct->new($type,$q,$ng);

my $oct = YAPE::Regex::oct->new(040);
# / 40/
my $text = $oct->text;
Returns the octal escape.
print $oct->text; # 40
my $type = $oct->type;
Returns the string oct.

Methods for YAPE::Regex::hex

This class represents hexadecimal escapes. Objects have the following methods:
my $hex = YAPE::Regex::hex->new($type,$q,$ng);
Creates a YAPE::Regex::hex object. Takes three arguments: the hexadecimal number (as a string), the quantity, and the non-greedy flag.
my $hex = YAPE::Regex::hex->new(20,{2,});
# /x20{2,}/
my $text = $hex->text;
Returns the hexadecimal escape.
print $hex->text; # x20
my $type = $hex->type;
Returns the string hex.

Methods for YAPE::Regex::utf8hex

This class represents UTF hexadecimal escapes. Objects have the following methods:

my $text = $utf8hex->text;
Returns the hexadecimal escape.
print $utf8hex->text; # x{beef}
my $type = $utf8hex->type;
Returns the string utf8hex.

Methods for YAPE::Regex::backref
