keyer

Looking around I didn't see any Crystal library built to handle processing the parameter data for GET and POST requests. The existing system just hands you a string and lets you manually deal with all the joined ampersands & and the nested form parameters.

This library lets you access the parameters with nested Hash-like behavior.

Installation

Add this to your application's shard.yml:

dependencies:
  keyer:
    github: danielpclark/keyer_cr

Usage

require "keyer"

v = Keyer::Parser.new("asdf=1234")
v["asdf"]?
# => "1234"
v["apple"]?
# => nil

v = Keyer::Parser.new("asdf[qwer]=1234")
v["asdf"]["qwer"]
# => "1234"

v = Keyer::Parser.new("a=7&asdf[qwer][poiu]=1234&cat=meow")
v["asdf"]["qwer"]["poiu"]
# => "1234"
v["a"]
# => "7"
v["cat"]
# => "meow"

With nested paramters you still need to take into account if one doesn't exist before going deeper.
