This example demonstrates recursive directory traversal as a streaming pipeline in Haskell, yielding each file path as a producer. The code uses the `Pipes` library, with `getRecursiveContents` recursively descending into subdirectories via `getDirectoryContents` and filtering out `.` and `..`. Each file path is then piped through `P.map` to prefix `"Found file "` and sent to `P.stdoutLn` for output. The main function takes a starting path from command-line arguments via `getArgs`, illustrating a functional, lazy approach to filesystem enumeration.

subdirectory files

This example demonstrates how to recursively traverse a directory structure using Python’s `os.walk` API to collect all file paths into a set, then prints the count and the set of relative paths. The visualization shows the logical hierarchy of files and folders, with the code relying on `os.path.relpath` to generate clean, relative file locations from the root directory. The rendering approach is text-based output rather than a graphical chart, emphasizing the data collection and enumeration process. The script’s behavior is limited to listing files, with no sorting, filtering, or graphical mapping applied.

Gist 0e59d1c2d63aaea35573

This example demonstrates benchmark-driven optimization of recursion schemes in Haskell, using the Criterion library’s `defaultMain`, `bgroup`, and `bench` functions to measure performance. The code defines catamorphisms (`ffold`), anamorphisms (`funfold`), hylomorphisms, and build functions (`fbuild`, `funbuild`), then applies them to natural numbers, lists, and trees. It highlights how `INLINE` pragmas and `RULES` for fusion (e.g., `ffold/fbuild`) improve execution speed, as shown in benchmarks like `lengthL`, `mapL`, and `depthT` over sample data structures.

Knuth/McIlroy word count task using Haskell

This example demonstrates a word-frequency analysis task using Haskell, showing how to compute and display the most common words from standard input. It chains data transformations through a pipeline: converting text to lowercase, replacing non-letter characters with newlines, splitting into words, and tallying counts with a hash map. The code relies on `Data.HashMap.Strict` for efficient key-value aggregation via `HashMap.fromListWith`, and uses `Data.List` for sorting and taking the top *n* results. The final output lists each word with its count, sorted in descending order of frequency. The example highlights functional composition and lazy evaluation in a concise, read-backwards data-flow style.

Gist 1ba2e157aea3eefadc42

This example shows how a large synthetic file hierarchy is created on a local file system, visualized as a tree-like directory structure. The code uses Python’s `os` module to programmatically create 50 top-level directories, each containing 1,000 subdirectories, and each subdirectory containing 1,000 text files, for a total of 50 million files. The file contents are identical placeholder text, and the visualization likely represents the nested structure using a tree or treemap layout, though the code itself only generates the data, not the graphic. No external visualization libraries are used in the provided script.

This example demonstrates a modular approach to building and testing effectful programs using the free monad pattern in Scala. It defines a `Free` monad to sequence interactions like console prompts and authentication checks, with interpreters separating execution from logic. The code uses type classes `Monad`, natural transformations (`~>`), and coproducts to compose independent algebras (`Interact` and `Auth`). It shows both a production interpreter (`Console`) and a pure test interpreter (`TestConsole`) that returns output lists from a static input map, highlighting how to decouple I/O from program structure.

search and read

This example demonstrates a file-searching utility that locates every `target.txt` file within a directory tree and prints its contents to the console. The code uses the `os.walk` API to traverse directories recursively, collecting paths where the target file exists, then opens and reads each matching file with Python’s built-in `open` function. The rendering approach is purely text-based, with output delivered as sequential lines from each located file. No external visualization libraries are employed; instead, the focus is on demonstrating filesystem traversal and conditional file matching through standard library functions.

navigate to the directory returned by a previous `which XXX`

This example demonstrates a terminal workflow for jumping directly into a source directory after locating an executable with `which`. The visualization, authored by BBischof as a gist, is a static diagram of the command sequence `cd $(dirname $(!!))`. It shows how the shell expands the `!!` history reference into the full `which` command, pipes that output through `dirname` via a command substitution, and feeds the resulting directory path to `cd`. Rendered as a text-based flow chart, it uses no external graphics libraries, relying solely on ASCII characters and shell syntax annotations to depict the process.

Gist of a stolen gist

This example visualizes the structure of a “stolen gist” — a curated piracy resource list — as an interactive hierarchical map. It shows the document’s nested sections and subsections as collapsible, color-coded nodes, revealing the organization of topics like torrenting, Usenet, and streaming. Built with React, it uses a custom recursive rendering of the markdown headings, with d3.forceSimulation to position nodes and CSS transitions for expand/collapse animations, sourced directly from the raw gist file.
