Go File Cache

This package provides easy to use, file system cache functions.

Full documentation is at: godoc.org/github.com/DannyBen/filecache

Install

$ go get github.com/DannyBen/filecache

Usage

Get the cache handler and set a cache directory and the requested cache life, in minutes:

handler := filecache.Handler{"./cache", 60}

Store data in the cache by providing a string key to the Set method and []byte data. The key's md5 checksum will be used as the filename.

data := []byte("Joey doesn't share food")
handler.Set("testkey", data)

Retrieve data from the cache:

r := handler.Get("testkey")
if r == nil {
	fmt.Println("Cache has expired")
} else  {
	fmt.Println(string(r))
}
