This example demonstrates a Ruby-based interactive editor that opens a temporary file in an external text editor, then executes the file’s contents as Ruby code within the current object’s context. The `InteractiveEditor` class initializes with a chosen editor (defaulting to `vim`, with `mate` mapped to `mate -w`), creates a `Tempfile` on demand, and uses `system` to launch the editor. After editing, the `execute` method reopens the file, reads it, and passes the content to `Object.class_eval` for evaluation. The code relies on Ruby’s standard `tempfile` library and the `system` command, with no external visualization or data dependencies.

This example configures an interactive Ruby IRB session by enabling auto-indentation and loading the Wirble and irb_edit libraries. It initializes Wirble and turns on its colorized output, which formats and highlights code and results in the terminal. The snippet relies on Ruby’s IRB configuration API (`IRB.conf`) and Wirble’s `init` and `colorize` methods, but it does not load or process any external data or perform any visualization.

This example demonstrates how to dynamically add instance methods to a Ruby class at runtime using `class_eval` and `define_method`. The code defines a `fun` method that takes a class, a method name, and a block, then injects the block as a new instance method on that class. Specifically, it adds a `world` method to the `String` class, which returns the string `"#{self} world"`. The final line calls `"Hello".world` and outputs `"Hello world"`, showing how the injected method operates on any string instance. The example relies purely on Ruby's core reflection and metaprogramming APIs, with no external libraries or data sources involved.

This example demonstrates a minimal Ruby script that temporarily redirects standard output to capture a string, then restores it and prints the captured content. It shows how to intercept output using `StringIO` and the global `$stdout` variable. The code assigns `$stdout` to a new `StringIO` object, prints "Hello, World!" into it, then restores the original standard output and outputs the captured string via `new_stdout.string`. The visible rendering is plain text output, with no external data source or graphical library involved.

This example visualizes the error-handling logic in Rails' fixture-loading code by presenting the source of two methods, `parse_yaml_string` and `erb_render`, as a static code excerpt. The visualization shows how a YAML parsing failure is caught and re-raised with a detailed `Fixture::FormatError` message that includes the original error class and message, while also demonstrating the separate ERB rendering step. The display relies on plain text rendering of the Ruby code from `gistfile1.txt`, with no interactive or graphical elements—it simply presents the two method definitions verbatim, highlighting the rescue clause and the embedded string interpolation in the error message.

This example renders a data-driven visualization using R and the brew templating system, processing text and code via `eval` to generate output. It demonstrates programmatic document composition, where the `brew.cat` function writes text segments to the output stream and code is executed within a specified environment, allowing for dynamic content generation. The implementation relies on the brew package’s core functions and base R I/O operations, with `sink` redirecting output to a file or connection when needed. The visualization itself is not a graphical chart but rather a scripted pipeline for producing structured textual or report-style output from data.

This example visualizes the terminal output of a failed Ruby Enterprise Edition installation, showing each command line and its associated error or status message. The data comes from a gist file containing the raw shell session text. It uses d3.js to render the log lines as a structured text layout, with color coding to distinguish normal output from error messages and italicized progress notes. The visualization employs standard DOM manipulation and text-wrapping techniques to display the chronological sequence of commands and their results.

This visualization shows the result of running Ruby code that attempts to load `rake/compiletask` twice, failing both times with a `LoadError` because the file does not exist. It presents a terminal session where the user first checks the MacRuby version, then tries to require the missing library, and finally verifies that `rake` loads successfully but the specific compile task file remains unavailable. The example uses the Ruby `require` method and the `rake` gem’s API to demonstrate a common error-handling scenario, highlighting the difference between loading a gem and accessing a non-existent sub-file. The data source is the literal command-line output and error messages from the user’s shell.

This example visualizes the configuration and plugin mappings from a user’s `.zshrc` and `.vimrc` files, revealing how shell and editor settings are organized. It presents the raw text content of these dotfiles, highlighting sections like PATH exports, theme selection, and Vim key remappings. The rendering uses plain text display with syntax highlighting, likely via a JavaScript library such as highlight.js, to delineate commented lines, variables, and Vim commands. The layout follows the file structure, making the hierarchy of settings and aliases directly readable.
