Chasing Rakudo bugs with Sparrow

Since I announced a RICH - Rakudo Issues Confirmation Helper, I've been playing a lot with an automation of test cases for known Rakudo bugs.One thing I've found really interesting in this journey is how Sparrow could be a good fit to express issues through automation scenarios. While I am not pretending on substituting existing …

Sparky on k8s cluster

Sparky is a lightweight CI server written on Raku. It uses Bailador for UI and Sparrow/Sparrowdo as an automation engine. Initially the server was written to be run on a single machine and did not scale well. So it only could handle a small/medium load, mostly working in localhost mode. Now, with the help of …

Rakudo Issues Player

Rakudo releases could be tough. Because the language is still in very development stage. New issues arrive daily. Let's me introduce my attempt to help release managers and Rakudo developers to keep track of addressing existing issues with daily Rakudo commits.

Lightweight Markdown-to-PDF converter: pfft

I Fight for the Users

I just released the first version of my new Markdown-to-PDF converter, pfft.  It runs on Linux, at least as far back as Ubuntu 18.04.

Why yet another converter when pandoc and many others already do the job?  Size.  Pandoc uses TeX to generate PDFs.  All the other converters I found use a Web browser in one way or another to make the PDF.  Pandoc is 50 MB by itself, not counting TeX!  In less than 1.2 MB (a 5.25″ floppy 😉 ) and a single file, pfft will do the job.

Of course, there is a catch: pfft uses Pango and Cairo to make the PDFs.  Those have their own dependencies, but are installed on many Ubuntu systems by default!  So pfft itself does not add to the dependency load those systems already carry.

(By the way, I use and appreciate both TeX and Pandoc.  They are great tools! …

Raku-Utils Proposal

Sparrow is a Raku based automation tool comes with the idea of Sparrow plugins - small reusable pieces of code, runs as a command line or Raku function. Raku: my %state = task-run "say name", "name", %( bird => "Sparrow" ); say %state<name>; Cli: $ s6 --plg-run name@bird=Sparrow One can even create wrappers for existing …
