Weird Grid Errors

Lookit! Perdy colors...

Now if only I can figure out why the labels are so far to the right...

Attempting to Draw using Terminal::Print

Here's code that should draw a progress bar and a label. It's not working. What am I doing wrong?

#!/usr/bin/env raku

#| A command-line program to display a customizable, colorful progress bar
#| Usage: raku progress-bar.raku <percentage>
#| Example: raku progress-bar.raku 75

Raku - An annoying thing about <Z>

An annoying thing about Z, zip, and roundrobin is that they don't allow you to use lists of differing sizes. I whipped up this custom infix to solve the problem:

multi sub infix:<ZZ> ($a is copy, $b is copy) {
  my ($larger, $smaller) = ($a, $b);

  if $a.elems != $b.elems {
    ($larger, $smaller) = ($a, $b) if $a.elems > $b.elems;

Browser Detection in Raku

Here's a snippet of untested code that one should be able to use to detect what type of browser you have based on the User Agent string:

use v6.d;

# Written by the Repl.It AI with prompts created by Clifton Wood
# Further exits for Racquet authored by Clifton Wood

#| A class to detect browser information from User-Agent strings

Reusable Code as Macros in Raku

I'm trying to write a generic macro that can produce code like the following:

method setAppName ($name) {
  $appName = $name;
  self.Applications::Bizzell::Inventory::Roles::DB::Threshold::setAppName(
    $name
  );
}
method appName { $appName }

Blender and Raku via Python

Would it be possible to access blender using Raku by having Raku emit python?

I'm thinking yes.

That way this:

view_layer = bpy.context.view_layer

# Create new light datablock.
