V7 Roadmap

[ApolloZhu]

New Features

There are many requests for other styles/code kinds, so probably some architectural redesign that's more modular to allow more customizations.

• style: use color gradient (Gradient dots support #91)
• style: round finder pattern (Diferent shape of Finder Pattern #68)
• type: data matrix (Support data_matrix codes #87)
• type: bar code (barcode support #63)
• type: txqr (TxQR support #56)

Archtecture Redesign (Draft)

The current generator handles a lot of functionality, and its complex behavior is only adjustable by the parameters it decides to expose, and all customizations have to be offered by us. Instead, we should consider composition.

The generator can probably be divided into 2 steps:

• CodePointGenerator, where input is the content and output is some 2D Bool array (or other types)
  • core library provides EFQRCodePointGenerator
• CodePointRenderer, where input is 2D bool array and can output to some sort of canvas (CGContext, SwiftUI canvas, ...)
  • what inspirations we can draw from string interpolation/codable (to support rendering custom types)?

Additionally, to make implementing renderer easier, the core library should provide helpers like

• QRCodePoint utility
  • given a coordinate, what kind of point it is? (e.g. part of timing pattern)
  • what are all the locations of a specific kind of point?

Obsoleted

• Everything inside EFQRCode+Migration-v6.swift will be marked with obsoleted instead of deprecated.
• EFQRCodeMode.none will be officially replaced by EFQRCodeMode?.none (i.e. nil), with a public static let that shows it's been renamed to nil.
