Test release for DBD::mysql available - ssl by default

Dear Perl and MySQL community,

We're pleased to announce the release of DBD::mysql 4.033_01, the Perl DBI driver for MySQL and MariaDB databases. This is not a 'stable' release but merely for testing and feedback. We'll put out a stable 4.034 release soon; probably before christmas.

Linking against SSL by default?

Apart from that, I'd like to announce that we might want to link to SSL by default. MySQL 5.7 makes SSL connections to databases more common; right now in DBD::mysql you'd need to pass an option to Makefile.PL (--ssl) in order to enable linking to libssl. Of course, many people (and linux distributions!) don't do this by default. On the expense of the added dependency to libssl we'd want to default to compiling against libssl. We'd introduce a --nossl flag for the cases where you'd explicitly NOT want to link to SSL. When DBD::mysql is compiled against libssl you can still make connections to not-sslified servers.

Any feedback (+1's, remarks or objections) would be appreciated!

OpenWRT and Perl, From December SydneyPM

My talk from this months SydneyPM. Wherein I install OpenWRT on to an inexpensive TP-Link pocket router, install perl and attempt to smoke CPAN.
I also introduce OpenWRT in possibly too much detail, and dont really explain what smoking CPAN is.

Kieren's talk was excellent, although he informs me that he wishes to expand and refine it for future use so will not be publishing it at this time.

Exception::Stringy - Modern exceptions for legacy code

Exception::Stringy - Modern exceptions for legacy code

A small recap of Perl exceptions

Basic Usage Of Exceptions

In Perl, exceptions are a well known and widely used mechanism. It is an old feature that has been enhanced over time. At the basic level, exceptions are triggered by the keyword die. Exceptions were initially used as a way to stop the execution of a program in case of a fatal error. The too famous line:

open my $fh, $file or die "failed to open '$file', error: $!";

is a good example.

The original way to catch exceptions in Perl has a somewhat strange syntax, it's based on the eval keyword and the special variable $@:

eval { code_that_may_die(); 1; }
  or say "exception has been caught: $@"

Yet Another 256colors Printer (App::256colors)

I was surprised to see there aren't any 256colors scripts installable from the CPAN. I have one I've been using locally for awhile, so I turned it into a proper module and uploaded it as App::256colors (first!).

Compared to the many other 256colors scripts floating around the internet, this one will print 256 color codes in both integer and hex/rgb format, which can be useful depending on what you're tweaking (e.g. Xdefaults vs PS1). I also think the output format is pretty nice (although I may be biased :) )

Based on the size of your terminal it will wrap the column output accordingly, as well as invoke the less pager with suitable options if the terminal is too small to display all the codes.

It's a pretty simple script, but I've found it invaluable for getting my color schemes "just right."

London Perl Workshop 2015 - a retrospective

The London Perl Workshop 2015 was the first workshop in a long time where I did not present a talk. This left me free to listen to the talks without worrying about my slides or wanting to go through my demo one more time. So, without further ado, here's my retrospective of the talks I saw:

A Date with CPAN, Part 5: Everything's Relative

[This is a post in my latest long-ass series.  You may want to begin at the beginning.  I do not promise that the next post in the series will be next week.  Just that I will eventually finish it, someday.  Unless I get hit by a bus.

IMPORTANT NOTE!  When I provide you links to code on GitHub, I’m giving you links to particular commits.  This allows me to show you the code as it was at the time the blog post was written and insures that the code references will make sense in the context of this post.  Just be aware that the latest version of the code may be very different.]


Last time I actually got down to it and wrote some code: Date::Easy now has a date constructor for turning arbitrary human-readable strings into date objects.  Now it’s time to expand on that and allow even more formats.

But first, we’ll do a bit of math.

Grammar reuse

My latest blog post looks at a grammar reuse, comparing regular expressions, PEG, Perl 6 grammars and general BNF parsers, including Marpa. A good property to have in itself, grammar reusability is crucial if a parser is going to be the basis for language-driven programming.

Release of Validator::Custom 1.01. more simple and more flexible interface is added

I released Validator::Custom 1.01. More simple and more flexible interface is added.
Document is rewrited completely. Backword compatible is kept completely.


Validator::Custom

  • Checking functions and filtering functions is added. You can use these in your source code.
  • A validation object which save the result of validation is added.

Usage

 You can use checking function and filtering functions. The validation result is saved to the validation object. You don't need to learn complex things.

Perl 5 Porters Mailing List Summary: November 30th - December 7th

Hey everyone,

Following is the p5p (Perl 5 Porters) mailing list summary for the past week, including the first Monday of this week. Enjoy!

Happy Hanukkah!

Although I am not Jewish, I wanted to post o/t and wish Happy Hanukkah to all my Jewish friends in the Perl community.

Also, thanks for a great excuse to eat jam donuts and charge it to the company.

pcorelist - a corelist wrapper with shell completion (App::Spec)

Maybe you've read my recent post about App::Spec.

As an example, I've written a wrapper around the corelist tool, which adds shell completion.

Since the options of the original tool weren't ideal for completion, I added subcommands.

Perl Versions, features and modules are completable.

The script is in part a wrapper around corelist, and partly I stole code from it.

I attached a little gif animation which shows the script in action:

Suspending efforts on my #riba2016 crowdfunding campaign, looking forward to my own Xmas

( If you want the text below narrated instead - watch the video, there is also an alternative comment thread on reddit )

On the 1st of October I launched a daring crowdfunding campaign. I asked over thirty companies directly relying on my open source work to split a rather modest bill, allowing me to exclusively focus for at least a year on several key parts of the Perl5 library repository (CPAN). Two months later, after a really promising start, the campaign is effectively dead.

The Veure MMORPG Saga Continues

I'm doing heater runs in Taungoo Station when someone tells me about a problem in Nouveau Limoges, another station in the Sol System. I mosey on down to the port, hop in Serenity, my corvette class spaceship (with some "quiet" modifications), and launch. Serenity's an older ship and she higher maintenance than I would like, but she keeps flying and that's good enough for me.

A little over 7 segments later (a long, boring flight), I arrive at Nouveau Limoges. And that's when the trouble kicks in. You see, I'm a Consortium citizen, but Nouveau Limoges is a Gaul station and I forgot to renew my visa. Immigration computers notice my status and I get auto-deported back to the station I came from: except I am still on Serenity and she doesn't have enough anti-matter reserves to make the flight back. An HTTP redirect loop ensues and ...

I found that bug hilarious and it will be fun to resolve. Sadly, it probably won't be me who fixes it, even though I want to dig in.

What will you get? You will get an official Dancer book written by the core team. You will get the latest features covered - Dancer2! You will get examples that cover practical usage - websites and web APIs. You will get our appreciation and thanks. And above all, you will get to know you helped sponsor a new Modern Perl book, by people who write modern software out of community interest and wrote the book for the benefit of the community and the language.

Sparrow article on habrahabr.ru

Hi! This is sparrow / swat related article http://habrahabr.ru/post/272245/ written on Russian language.

Fixed 5.22 problems during my compiler port

I uncovered and fixed many 5.22 problems with cperl already, but in the last months I was busy to port the 3 compilers B::C, B::CC and B::Bytecode to 5.22.

As I said in my interview it's my belief that if all current p5p core committers would stop committing their bad code it would be actually be the best for the perl5 project. They weren't able to implemented any of the already properly designed features from perl6 in the last 12 years, and every feature they did implement is just so horrifibly bad, making our already bad code base, which led to reimplementation efforts of perl6/parrot with a better core, even worse. With cperl I can only undo a little, but when they start breaking the API and planned features in an incompatible way they should just stop.

Nevertheless, 5.22 added a significant improvement from outside, syber's monomorphic inline caching for method calls besides the internal improvement of multideref by Dave Mitchell.
