Thank you Saif, yes that what I meant by the last paragraph of this post. Changable Colors (using Graphics::Toolkit::Color ofc) and more complex mobility (action rules). And Pro Tip: if you draw greater PNG, more cells will be computed....

To continue my previous post about Kephra, please let me ramble about just one seemingly little feature. It is interesting in its own right - but also an example for the design principles I employ:

Posted Return of Kephra to lichtkind
Juhuu, released Kephra 0.401 in the spirit release early - release often. It is the start of a complete rewrite. So it's back to zero: now it can only edit one file at a time and has only Perl highlighting and UTF-8 or ASCII encoding. But some of you will still want to use it (beside vi, emacs,…

Posted course change for Kephra to lichtkind
Kephra, an editor for programming (mostly Perl) written in WxPerl is my main project since I stumbled into the Perl community. Most people I know already heard of it - but I want to write about a new development that might be helpful for some, which might consider to use it even if it has a very…

Posted In defence of OOP to lichtkind
During the last years it became fashionable to rag on object oriented programming and a decade ago I would join the choir. Hack, when I started with Perl I despised the bloat and inefficiency of many corporate smelling *coughjava* systems and preached the light weight and foreward thinking way…

Welcome to the fifth post about the Kephra Base Object System, where I explain the need for three kinds of attributes: data, delegating and wrapping and gas a little about their properties. It is especially advised to have read the

Posted KBOS types to lichtkind
After introducing KBOS I should write about the most fundamental concept in this Perl syntax extension. In fact it's so basic, you could use it even without objects.

well, KBOS classes are not ment to be inherited from. If you define a class Bumblebee, there will be later no package Bumblebee, let alone subs in it, so parent would run empty. All information which methods and attributes the...

i see your issue, but luckily I don't have even think about and hut my precious brain, because KBOS has no inheritance (for reasons like you present here and as written in the post). But to fully adress you question,...

Posted Introducing KBOS to lichtkind
Starting even before Moose, we (in the Perl 5 world) have a plethora of Modules extending the syntax of the language with Perl 6 and more in mind. The following article sums up not only my 2 and a half cents on the subject but also an attempt to implement it. It should be of interest to anybody…

TPF launches merch store for Perl 5
It is inspired by but not a derivative work of the perl 5 raptor logo https://github.com/kraih/perl-raptor

TPF launches merch store for Perl 5
The "Raptor logo" is not the _real_ Perl logo; everybody knows that is a camel. The raptor is a Mojo creation. This is just weakening the brand.
Also, it's sowing confusion to have PERL in capital letters given how much we have to correct people for using that rendering.
This 25-year Perl programmer won't be buying one -- and I would love to have some good new Perl attire.

TPF doesnt own a camel logo, it only owns the Onion logo and as of the last few weeks the Camelia logo for Raku.

The raptor is a Mojo creation.
Incorrect. All three logos in fact go back to remarks by Larry, including the velociraptor.
The earliest reference to the velociraptor by Larry that I can find is in Apocalpyse 12, where he only mentions it as a joke. Matt Trout later attributed to him a quote that “perl5 is a velociraptor. What we need now is an acceloraptor” (i.e. Perl 6 (at the time)) – though I am unable to substantiate this…
