A brain library for generating turtle graphics commands that could potentially be interpreted to draw awesome turtle based graphics!

NOTE: This is not a working example of anything yet. This library is being developed so that future versions of the language will be able to use it. This gives us an idea of what a full library in brain would look like.

use package turtle;

for _ in 0..3 {
  turtle::forward(100);
  turtle::turn(120);
}

These are enhancements that could happen very soon, but we are just not sure how yet.

• Getting values for turtle properties (pen::is_down(), etc.)
  • This is a hard problem because we don't keep any state so we would have to query with an output command and then read/parse input. Parsing is hard because we don't have a very sophisticated IO model. Maybe with a good, buffered IO library we could support parsing. This means that we would have to wait for the allocator to get implemented.
• Unit tests
  • This will require a unit testing framework to be built.

• Floating point arguments
