SCRIPT-8

A small pixel-art character walks horizontally across a blank map in this SCRIPT-8 cassette. The example shows sprite animation and keyboard-driven movement using the SCRIPT-8 API, including `sprite()`, `map()`, `clear()`, and the `update`/`draw` loop. Left and right arrow inputs adjust the character’s x-coordinate and flip its facing direction, while its y-coordinate stays fixed. The visible sprite definitions come from `sprites.json`, which stores the character and a second tile, though only the first is rendered in the draw function.

SCRIPT-8

A tiny SCRIPT-8 cassette draws the text "Hello world!" at coordinates (42, 60) using the built-in `print` function. The code is minimal, consisting solely of a `draw` callback that executes once per frame, rendering the message in the default font on the canvas. No data, sprites, maps, or songs are loaded, making it a pure text-output demonstration of the SCRIPT-8 API.

This example shows how to test authorization and role-protected attribute updates in a Rails controller using RSpec. It verifies that a user cannot edit another user’s profile, can change their own given name, and cannot modify their role field, with assertions on flash messages, response codes, and assigned attributes. The code uses Devise::TestHelpers to sign in a factory-built user, and RSpec’s `describe`, `context`, and `it` blocks to structure the test cases.

This example demonstrates a simple Ruby class called `Element` that stores attributes in an instance variable and iterates over them with a `do_something` method, printing each attribute using `p`. The visualization shows a basic object-oriented data-handling pattern rather than graphical output. It relies on core Ruby language features—class definition, initialization, and attribute iteration—without external libraries or rendering APIs. The code serves as a minimal illustration of how structured data can be encapsulated and processed in Ruby.

This example shows a page where the body text is rendered using the Cufón font replacement library, which swaps standard HTML text for canvas-based vector fonts. The code calls `Cufon.replace('body')` to apply a custom typeface to all body content, improving typographic control without requiring the user to have the font installed. The visualization is purely typographic, with no data or chart elements; it demonstrates how Cufón intercepts text rendering and draws it via its own canvas API. The approach relies on the library’s internal parsing and redrawing of DOM text nodes.
