Migrating from Mojolicious::Plugin::Swagger2 to OpenAPI

Mojolicious::Plugin::OpenAPI is close to being stable so i figured it was time to migrate from our use of Mojolicious::Plugin::Swagger2. Here's the differences i found, with the observation that perhaps some of these were down to having an older version of Swagger2 (0.79, although Changes log suggests that might not be the case):

Teach Makefile.PL to use cpanm

I like to keep my perl modules lean when it comes to dependencies. But then again, CPAN is just so wonderful with all the helpful packages available. So there are always dependencies.

When writing perl modules, more often than not a few dependencies creep in … which makes it a whee bit awkward when developing the module, because I then have to somehow install these dependencies, and I would rather not get them all over the place but neatly in the module directory so that I have at least a semblance of a stable development environment.

So here goes my solution: A little postamble method for my Makefile.PL.

Portable GitHub system "GitPrep 2.3" is released - At last, "Issues system" is added. "Bug tracking" available!

Portable GitHub system "GitPrep 2.3" is released at 2016-08-06.

Finally, "issues" system is added. You can use "Bug tracking" on GitPrep.

And contain bug fixing, added features.

  • support issues system
  • support markdown table
  • support markdown foo_bar_baz

At first, Let's try
GitPrep example. You will find GitPrep is real portable GitHub system.

The features of GitPrep

I introduce the featrues of GitPrep for people who see GitPrep for the first time.

  • Github clone: GitPrep has the same interface as GitHub.
  • Support issue system
  • Portable: You can install GitPrep on your own Unix/Linux server.
  • Only needs Perl 5.10.1+.
  • Smart HTTP support: you can pull and push repository via HTTP.
  • Built-in web server, and reverse proxy support.
  • CGI support.
  • SSL support.
  • Public key authentication support

Installation is very easy. You run only two commands. Difficult settings is unnecessary.

Even if you have troubles by your mistake, for example "git push -f origin master", you can access all of your git repositories directory and fix them.

i have multiple files open, then when i click on one of the
tabs to close 1 file, padre crashes without an error message,
the application just closes.
this also happens when i save the session.
kinda frustrating.
do you discuss padre here or am i in the wrong forum?
thank a bunch in advance

Perl 6 Core Hacking: Where's Da Sauce, Boss?

Read this article on Perl6.Party

Imagine you were playing with Perl 6 and you came across a buglet or you were having some fun with the Perl 6 bug queue—you'd like to debug a particular core subroutine or method, so where's the source for it at?

Asked such a question, you might be told it's in Rakudo compiler's GitHub repository. Depending on how deep down the rabbit hole you wish to go, you may also stop by NQP's repo, which is a subset of Perl 6 that's used in Rakudo, or the MoarVM's repo, which is the leading virtual machine Perl 6 runs on.

The answer is fine, but we can do better. We'd like to know exactly where da sauce is.

Stick to The Basics

The most obvious way is to just use grep command in the source repository. The code is likely in src/ directory, or src/core more specifically.

We'll use a regex that catches sub, method, and multi keywords. For example, here's our search for path sub or method:

Perl's Pegex Module: a great way to parse files by creating grammars

We recently came across Pegex and found it to be an interesting module for parsing text data. Instead of using regular expressions directly, the user can write a grammar for the data to be parsed. The data can be automatically converted to a native Perl object or, if the user desires, it's possible to use actions to handle the grammar while parsing using a Pegex::Receiver class.

Pegex uses the type of grammars called Parsing Expression Grammars (PEG), which is an unambiguous form of writing a grammar. Each parsed string will in effect have a single valid parse tree. Since Pegex converts the rules of the grammar to regular expressions, it is a greedy parser.

In this blog post we demonstrate how to easily use Pegex to parse an /etc/hosts file on Linux and convert the result into Perl objects automatically without having to manually create any object.
