Today in the Dist-Pen I am going to have a quick Post-ette.
In yesterday’s post I was a little disappointed with Dist::Zilla::Plugin::Test::Legal not working, so for today’s post I was going to have a look at it and see why.
Well to start off I did do a force install yesterday which is never a good way to do things but I was a little short of time. Looking at the code in Dist::Zilla::Plugin::Test::Legal the part I we are interested in is only a few lines long;Scott Wiersdorf's presentation on Kubernetes and how to use it to deploy your Perl applications.
Perlmodules.net, the site that notifies you about new releases of your favorite modules, just got better for groups, with Multi-User feeds.
If you're part of a project team, and wish to have your team members be able to view and/or modify your feed(s), as of today you can.
The owner of the feed grants read or write access rights to any users they want. If one of these guest users modify the owner's feed (i.e. adds or removes some modules which are tracked by this feed), the owner will get notified by email about all modifications at the end of the day (only if such modifications have occurred).
I've never written games before, but I previously posted a Hangman that I thought was fun. I love the examples of forest fire and Game of Life and wanted to create something like those. I originally wanted to create Pong but decided to try a simple ball that bounces off the walls of a container.
I showed this to my daughter, and she asked if there could be more than one ball, so I added that. They don't, however, bounce off each other, and this gets at the same problem I was mulling with regard to adding obstacles in the field that should deflect the balls. I have a feeling that two-dimensional arrays would help me add this feature. Support for that is coming. Anyway, on to the script!
Well seven more sisters to have a look at in today Dist-Pen
# FIXME – Replace this with a fractal algorithm
Hey everyone,
Following is the p5p (Perl 5 Porters) mailing list summary for the past week.
Enjoy!
I started gathering requirements for the next version of Asciio which will probably be written in Perl6 (Go is a strong contender albeit not as much fun)
Help by adding your requirements as an issue at https://github.com/nkh/Asciio-2.0
Integration with Ditaa is on the list since someone made most of the work, without even contacting me once. http://wiki.cornempire.net/_media/asciiart/diagram2.png
SVG output will be via a2s, https://github.com/dhobsd/asciitosvg, as the author is already an asciio user and some of his users are too.
The project welcomes help.
Karen Pauley Steps Down as TPF President
Come gather around people
Wherever you roam
And admit that the waters
Around you have grown
(The Times They Are A-Changin' lyrics © Bob Dylan Music Co.)
As of the 7th November 2016 Karen Pauley has officially stepped down as President of the Perl Foundation. Replacing Karen at this present time will be long standing Perl Foundation member Jim Brandt
So that is how it is officially announced and let’s quickly move away from such formal tones for the rest of this article.
It is with a great sense of melancholy, and probably an even profounder sense of respect and gratitude that I am writing this piece so please bear with me if the style seems somewhat stilted or unusual. I know that some people will feel regret at the loss of Karen, I want to stop you all now, don’t think about what we may be losing, think of the changes that have been made.
Its plow though some more test plug-ins day again here in the Dist-Pen.
So in my last post had found one plug-in that was useful, today I hope to find another from this list of Dist::Zilla::Test plug-inA new trial of Log::Any (1.044) has been released. This release has a couple changes that make Log::Any a bit more predictable:
use Log::Any '$log') can now be named anything (like $LOG or $foo).Since CPAN Testers is still catching up from its little bit of downtime a few weeks ago, I won't be releasing this as stable until I get some success reports in. So, you've got some time to test this against your own codebase if you need to. Please report any issues to the Log-Any Github repository.
The shader is a modification of a shader by Inigo Quilez, hacked up by Weyland.
After the initial rush of success, I spent this week working more on the UI side of the app, putting off adding support for geometry generation for later. Prima proves to be a solid UI toolkit and to me it feels closer to using Delphi or Visual Basic, API wise.
There's no question that DBIx::Class is the dominant ORM in Perl. That's because it's fast, it's flexible, and sane. Well, mostly sane, until you need some introspection (if anyone knows a better way to do this, I'm all ears!):
sub _get_json_columns ( $self, $schema_class ) {
state $json_columns_for = {};
unless ( exists $json_columns_for->{$schema_class} ) {
my $columns = $self->schema->resultset($schema_class)
->result_source->columns_info;
$json_columns_for->{$schema_class}
= [ grep { 'json' eq $columns->{$_}{data_type} } keys %$columns ];
}
return $json_columns_for->{$schema_class};
}
But what's terribly frustrating to many devs is getting DBIx::Class to show the queries it's executing, along with the bind parameters (one without the other is often useless).
Yeah another test play-date here in the Dist-Pen.
Playing with testing and Dist::Zilla over the last few posts has not only introduced me to a the newer 'Perlish' way to ogranize your test cases but I have seen a good number of plug-ins that might be interesting for me to add into my '.ini' file. Now besides the two I really wanted and have added in '[Test::Kwalitee]' and '[Test::Perl::Critic]' I know very little about the others so I am just going to plow though them alphabetically.
So my first batch of test plug-ins for today are
And suddenly I remembered that I promised myself, at YAPC::EU, that I would write a tmux plugin to implement a yakuake like pane handling.
With some time and energy on my hands I created a directory, initialize a repo and was on my way to write some perl. I took one hour to draw a few ideas and that's when GranPa Bash knocked at the door.
I know, you know, everyone knows that Perl build a lot on bash, at least its syntax, and in this very case it seemed to me that writing this in Bash would be better. It's mainly command calling, there is no complicated process to map, it should be quite easy in bash.
And I was in the mood!
Every second year I beat myself up because I always refuse to learn more sed or awk. It's not that I don't use them, it's just that every time I do, I get so frustrated that I end up writing some Perl.
This post was originally going to be an exhortation to potential speakers, to take the plunge and submit a proposal to the London Perl Workshop. I thought I could list some generic types of talks.
Then I realised I'm not entirely sure what kind of talks everyone is going to want to attend. So instead, I'm asking you, particularly if you're going to be at the LPW:
What talks would you be interested in attending?
Lessons learned developing modules? Comparisons of similar modules? How to use specific modules (which ones?)? Do's and Don'ts when developing with Perl (frameworks)? Experiences transitioning from Perl 5 to Perl 6, or vice versa?
Please add comments with the kind of talks you're interested in, as that might encourage people to submit talk proposals.
I have been granted co-maintainership of DateTime-Calendar-Christian, and version 0.04_01 went out October 30. Because this module is new to me, and because this is the first release in 13 years, I would like to encourage anyone with an interest in it to try out the new release and let me know of any problems.
The current release migrates the module to the DateTime locale interface, replacing the long-deprecated and recently removed language interface, and adds a today() instantiator. I hope to see enough CPAN testers results by the weekend to give me the confidence that I can do a production release
The plan is for subsequent releases to clean up the code, upgrade the metadata, and implement the DateTime interface more fully.
“The covers of this book are too far apart.” ― Ambrose Biercehmm criticism, of a fashion, but not much good to us in the Perl world, I much prefer;
“Criticism may not be agreeable, but it is necessary. It fulfills the same function as pain in the human body; it calls attention to the development of an unhealthy state of things. If it is heeded in time, danger may be averted; if it is suppressed, a fatal distemper may develop."― Winston S. Churchill
For a long time, I've wanted to actually make use of the modern hardware I have at home. The graphics card is capable of OpenGL and OpenGL now has a fancy little language to actually bring images to life. For example [https://www.shadertoy.com] has great so-called "shaders" that show off what can be done with them.
Because I also want to toy around with programming some shaders, I want to get a live environment running. So during the weekend, I took the Glew library, wrote a small Perl script to convert the header files to XS, and then fought with OpenGL until I had a driver that could run shaders from Shadertoy.com:
Hey everyone,
Following is the p5p (Perl 5 Porters) mailing list summary for the past two weeks.
Enjoy!
In bioinformatics, we get data from the sequencing centers usually in BAM or FASTQ format. One of the first steps is to QC the data to remove any reads that have very low quality or which are too short to use. Some sequencing technologies read from both the beginning and the end of the sequence in opposite directions, and so you need to put the reads together. Quite often one of the directional reads (forward or "R1", backward or "R2") are lost to QC, and so those are considered "singletons" that can't be paired with their read mate.
The boss wanted me to write a read pairer in Perl 6 for our class. Challenge accepted! Below is a decent working version, but it's dog slow ("dog" being Mississippi for "very"). Comments welcome!
