#zerkel An adzerk-based query-ish language.

###Language Zerkel exposes basic logic operators. The included operators are:

• AND
• OR
• NOT
• =
• <> (not equal)
• <

• =

• <=
• CONTAINS

Thus, queries may be written like:

count > 43 and (user = "bob" or user = "alice")
keywords contains "awesome"

All operators are available in upper and lowercase forms.

###Usage Queries can executed in coffeescript/javascript using the zerkel module, like so:

zerkel = require 'zerkel'

query = 'count > 43 and (user = "bob" or user = "alice")'
matchFn = zerkel.compile query
matchFn {count: 50, user: 'bob'} # true
matchFn {count: 12, user: 'alice'} # false
matchFn {count: 50, user: 'George Michael'} # terribly, unfortunately, false

You can also access properties on passed in objects, like so:

zerkel = require 'zerkel'

query = 'user.location = "open field west of a white house"'
matchFn = zerkel.compile query
matchFn {user: {name: 'bob', location: 'open field west of a white house'}} # true
matchFn {user: {name: 'alice', location: 'middle earth'}} # false
