Here's a quickly thrown-together version of "Fun with logical expressions", written in Haskell:
Part II of a series on Apache's mod_rewrite.
MarpaX::Languages::M4 package is a Marpa::R2/Moops powered implementation of it, 99% with the GNU M4 version () and have switches to alter its behaviour as wanted, so that one can have e.g. POSIX M4 as well.
MarpaX::Languages::M4 is distributed with an
m4pp command-line, with all the GNU M4 implementation options, plus some other handy items, for example:
- conversion to UNIX native end-of-line
- comment start and end delimiters
- string start and end delimiters
and some "advanced" options to alter the behaviour or extend M4 as you wish:
Addendum 2: This set of rules is incomplete. See Fun with logical expressions 2 for an improved version.
Addendum: I've written a more or less equivalent Haskell version of this program.
Some programmers, when confronted with a boolean expression, think "I know, I'll use regular expressions". Now they have
This post was inspired by the TAUT exercise on SPOJ.
You're given a boolean expression consisting of variables (each being either
false), a unary operator (
not), and several binary operators (
equals). Your task is to determine whether the expression is a tautology, i.e. whether it evaluates to
true for all possible variable values.
To make parsing easier, we're going to use a very simplified syntax:

The last three months have been some of the most professionally productive months I've had in years. In true Perl fashion, it all boils down to a Perl-related "hack" with StickK.com.
I am looking to contact Jochen Wiedmann who is the BZ::Client author (amongst other modules) whom I am guessing resides in Finland. I have emailed the associated cpan.org email address and I created an RT ticket 1 year ago. Hopefully ownership of this module can be shared and development continued.
In the interim, users of BZ::Client (i.e. Bugzilla XMLRPC Client) might be interested in my GitHub Repo which includes a number of patches.
Update: Contact has been made! Persons with patches for BZ::Client are encouraged to submit them via GitHub for inclusion in a soon to be released new version.
