Cookbook.Project.Quill2.Q2Prelude

Description

Q2Prelude is the entry-level module for Quill2. It defines the data types that define data, databases, and errors throughout the rest of Quill2.

Synopsis

Documentation

The body of a table or list.

Constructors

List [a]
Table [(a, a)]

Instances

Eq a => Eq (Element a) Source #
Methods (==) :: Element a -> Element a -> Bool # (/=) :: Element a -> Element a -> Bool #
Show a => Show (Element a) Source #
Methods showsPrec :: Int -> Element a -> ShowS # show :: Element a -> String # showList :: [Element a] -> ShowS #

Helper type. Binds a name to a body.

Encapsulates errors in the quill database. Currently supports Missing elements and Multiple Instances.

Constructors

Instances

Eq a => Eq (QuillStatus a) Source #
Methods (==) :: QuillStatus a -> QuillStatus a -> Bool # (/=) :: QuillStatus a -> QuillStatus a -> Bool #
Show a => Show (QuillStatus a) Source #
Methods showsPrec :: Int -> QuillStatus a -> ShowS # show :: QuillStatus a -> String # showList :: [QuillStatus a] -> ShowS #

Safe way of adding items to a Quill database. Allows type-checking on Lists and Tables when manipulating Elements.

Constructors

AList (String, String)
ATable (String, String, String)

Instances

Eq QuillAddition Source #
Methods (==) :: QuillAddition -> QuillAddition -> Bool # (/=) :: QuillAddition -> QuillAddition -> Bool #
Show QuillAddition Source #
Methods showsPrec :: Int -> QuillAddition -> ShowS # show :: QuillAddition -> String # showList :: [QuillAddition] -> ShowS #
