Java data structures for primitive and/or Object items
A implementation of a Java-like Set data structure for PHP. A Set allows storage of any value without duplicates which can be iterated in insertion order.
Like HashSet but retaining INSERTION order and without `Hash` requirement on the Element type.
Integer-keyed hash map that preserves insertion order: compact dictionary design, Fibonacci hashing, 64-bit keys and values on every build, and lookups several times faster than PureBasic's built-in Map.
Google Apps Script that turns rows of insertion order data in a Google Sheet into formatted one-page PDFs saved to Drive.
