WHAT IS LIBPHUTIL?
libphutil is a collection of utility classes and functions for PHP. Some features of the library include:
libphutil Library System
A system for organizing, loading and introspecting PHP classes and functions. Uses static analysis to generate, validate and update library contents and includes. Based on Facebook's similar 'flib' system.
Futures (also known as "promises") are objects which act as placeholders for some future result of computation. They let you express parallel and asynchronous execution with a natural syntax. There are two provided concrete Future implementations: ExecFuture for executing system commands, and HTTPFuture for making HTTP requests.
The builtin PHP filesystem functions return error codes and emit warnings. It is tedious to check these consistently. The Filesystem class provides a simple API for common filesystem operations that throws exceptions on failure.
An abstract, abstract syntax tree which can make it easier to perform simple static analysis, and a concrete AST for PHP.
A Markdown-like lightweight markup language. Remarkup's syntax is defined by parser plugins and fairly easy to extend and configure.
Enables running PHP scripts as stable, long-lived daemons.
A handful of solid utility functions.
libphutil is used by Phabricator, Arcanist and Diviner.
