Fractal Christmas Tree

[wbraswell]

Which Perl module do you want to write about: MathPerl::Fractal::ChristmasTree

Please give a short description of the article you want to write. Two to three sentences is fine: I'll develop a unique fractal algorithm for generating Christmas Tree graphics, hopefully with panning and zooming abilities as well. This should be interesting to those inclined toward mathematics, graphics programming, or the general Perl Christmas spirit! Note: this module does not exist yet, but its sister modules Julia and Mandelbrot do.

This sounds interesting. Might I suggest various discrete/space-filling things like Hilbert, Dragon or Siepersinki?

[briandfoy]

There's now a script to start your article for you and show off the pod enhancements you can use:

perl script/new_article

Good luck!

@wbraswell Gentle reminder 😄

[oalders]

Thank you so much for committing to provide an article to the Perl Advent calendar. It's a tradition that so many of us look forward to and we're happy you've volunteered your time to help us make 2022's calendar a success. Now, the initial submission deadline for an initial draft was Nov 1, 2022, but it's not too late to participate. We want help you to get your article merged. In order to avoid having the Advent Calendar team work furiously through the Holiday season in a rush to complete the calendar, we're asking you to submit your post by Dec 1, which is one week from today.

If we haven't heard from you by Dec 1st we will sadly need to close this issue and continue on without your article. We hope very much to make it to the magical number of 25 articles, but in order to accomplish this we need everyone who has offered to write an article to provide it. Please help us to make 2022 a year with a full calendar of fun, interesting and quirky Advent articles.

Hi Olaf, sorry I didn't realize the deadline is November 1st, yes I'm already working on my article now during the Thanksgiving holiday!

[oalders]

Excellent. Happy Thanksgiving, @wbraswell!

[wbraswell]

@oalders Just a quick update, I'm almost done with the code, will commence with writing the article today: https://github.com/wbraswell/mathperl/blob/master/script/sierpinski_triangle.pl

[wbraswell]

Animated Christmas tree code now completed, including graceful exit which is not exactly straightforward in SDL... https://github.com/wbraswell/mathperl/commit/4ccb4b4f0dc77852d2bee9d400f87c9a03a4b47a

The code is all self-documenting and contained in 1 file, so I will just need to write a short article with example output. Almost there! :-)

[wbraswell]

@briandfoy Is there an easy example of how to enable Perl syntax highlighting (presumably via Pod::Elemental::Transformer::SynHi) for my POD article?

[oalders]

You could follow this example: https://raw.githubusercontent.com/perladvent/Perl-Advent/main/2022/articles/2022-12-01.pod or https://raw.githubusercontent.com/perladvent/Perl-Advent/main/2022/articles/2022-12-02.pod

Either should be fine.

[wbraswell]

@oalders How do I see the output of Pod::Elemental::Transformer::SynHi on my POD file?

[wbraswell]

In other words, how do I see this: https://perladvent.org/2022/2022-12-01.html instead of just this: https://raw.githubusercontent.com/perladvent/Perl-Advent/main/2022/articles/2022-12-01.pod

[oalders]

You can run this script from the top level of this repo:

https://github.com/perladvent/Perl-Advent/blob/main/script/build-site.sh

Then:

cd out
plackup -MPlack::App::Directory -e 'Plack::App::Directory->new(root=>".");' -p 8080

Having said that, in order to see your article, you'll need to move a copy of the pod to the 2022/articles directory before building the site. Just give it a name where the date is from anywhere in the range from 1-25 and it should build for you. (Just like the other articles in that dir).

[wbraswell]

@oalders I'm getting an error from advcal, can you please assist?

[oalders]

You can either delete the --https from build-site.sh or you can install the fork of WWW::AdventCalendar which is in this branch. https://github.com/perladvent/WWW-AdventCalendar/tree/perladvent

First option would be easier as SSL shouldn't be an issue locally. We've had to work around a couple of issues in the CPAN version of that module.

[wbraswell]

Okay removing the --https from build-site.sh worked! However, now advcal only wants to build the first 7 days of 2022 for some weird reason??? (I disabled the previous years for brevity, they all appeared to build correctly.)

[openstrike]

It's the 7th of December and that's not a coincidence. :)

If you are intending to preview one of the other articles just move/rename it to an available date and re-generate.

[wbraswell]

@openstrike Okay great, thanks!
