rapid: GHCi background threads, hot reloading and reload-surviving values

[ bsd3, development, library ] [ Propose Tags ]

This package provides a safe and convenient wrapper around foreign-store for hot-reloadable background threads during a GHCi session, useful for the development of long-running programs like servers, web applications and interactive user interfaces.

It can also be used in the context of batch-style programs to keep resources that are expensive to create in memory instead of having to recreate them after every module reload.

Introduction

This is a helper library for rapid prototyping in GHCi sessions. It provides hot-reloadable background threads as well as values that can be reused across module reloads (to save initialisation time). Main use cases include the development of long-running applications, especially those with multiple separable units: servers, web applications, interactive user interfaces, etc.

A tutorial-style introduction is contained within the Rapid module.
