Get the byte length of an ArrayBuffer, even in engines without a `.byteLength` method.
Create mutable 2D arrays that allow you to change subarrays.
Implementation of 2D array
A dimensionable graph that acts kinda like a grid. You can fill in spots with objects and then iterate over the entire grid or just objects. Now, there is a new concept called truthy which will return given a certain condition. Each object in the graph can be given a truthy? method and you can use that to iterate through objects in the graphs more efficiently.
Generate a grid based heatmap from a 2d array using rmagick. Requires ImageMagick. Work in progress.
convert 2D array to markdown table
For a 2D array: A method which, when passed a term or array of terms, returns a hash as {term=>[[row,column]]}.
The arr2hash gem provides a simple way to convert a 2D array into an array of hashes. The first row of the 2D array is used as the keys, and the subsequent rows are converted to values, creating an array of hashes. This is especially useful for converting structured data like CSV.
A gem that procedurally generates a seeded and customizable 2D map with optional roads using perlin noise. Map can be rendered in console using ansi colors or returned as 2D array of hashes describing each tile and binome. Completely customizable, use the --help option for full usage details.
