HAL vector

HTTP Accept-Language vector parser. Based on accept-language-parser library, but based on vector parser instead of regexp due to performance reasons and reduce pointers policy.

Usage

src := "fr-CA,fr;q=0.2,en-US;q=0.6,en;q=0.4,*;q=0.5"
vec := halvector.Acquire()
defer halvector.Release(vec)
_ = vec.ParseStr(src)
vec.Sort().Root().Each(func(idx int, node *vector.Node) {
	print(idx, ":")
	println("code:", node.GetString("code"))
	println("script:", node.GetString("script"))
	println("region:", node.GetString("region"))
	q, _ := node.Get("quality").Float()
	println("quality:", q)
})

Output:

region: CA
quality: +1.000000e+000
