# recache

Package `recache` is a lightweight caching library for [Go's standard regular
expression package](https://godocs.io/regexp) that offers improved performance
by avoiding recompilation of global regular expression variables and by caching
regular expressions.

## Features

- Stable cache interface.
- Simple and easy-to-use API.
- Thread-safe caching of compiled regular expressions.
- Lazy compilation of regular expressions.
- Minimal memory allocations.


### `recache.Cache` implementations

The `recache` package itself only provides a cache interface and some utility
functions for users who wish to implement that interface. You can either use an
implementation created by someone else or write your own.

**Implementations**

- [`lrure`](https://git.sr.ht/~jamesponddotco/recache-go/tree/trunk/item/lrure)
  provides a thread-safe in-memory cache using the [least recently used
  (LRU)](https://en.wikipedia.org/wiki/Cache_replacement_policies#Least_recently_used_(LRU))
  cache replacement policy.

If wrote a `recache.Cache` implementation and wish it to be linked here,
[please send a patch](https://git.sr.ht/~jamesponddotco/recache-go#resources).

## Installation

To install `recache` alone, run:

```sh
go get git.sr.ht/~jamesponddotco/recache-go
