Bitarf RI is a rebuilt database for an iOS scroll-based layout editor app in Traditional Chinese. It preserves the code for document management, canvas editing, text typesetting, vector and image import, gradient filling, preview, and basic Bluetooth interfaces, and provides reconstruction prompts for a coding agent with a complete implementation of 384-dot continuous-feed dot-matrix printer hardware, using a “classic model” as an example.
Project Contents
- Bitarf RI/: SwiftUI, UIKit, documentation, editor, and resource scaffolding for the iOS app.
- Sources/BitarfRICore/: Core components such as the document model, canvas objects, typesetting, color mapping, and dot matrix processing.
- Bitarf RI.xcodeproj/: Xcode project.
This repository does not contain the original Git history, signing certificates, provisioning profiles, Apple Team ID, developer accounts, test data, or build artifacts.
Usage Instructions
This repository is incomplete and cannot be built directly. After pulling the project, use a coding agent (a program that automates code generation) to implement the missing protocols, hardware profiles, BLE adapters, print jobs, and test parameters to complete the reconstruction and create an executable Xcode iOS app project.
First, instruct the coding agent to read README.md. Have the coding agent locate the prompt files corresponding to the missing features. Each folder with a hardware gap contains only one prompt file, and its content covers only the files directly contained within that folder. The prompt files for rebuilding include:
- Bitarf RI.md
- Sources/BitarfRICore/BitarfRICore.md
- Bitarf RI/Bitarf RI.md
- Bitarf RI/App/App.md
- Bitarf RI/Canvas/Canvas.md
- Bitarf RI/Model/Model.md
- Bitarf RI/Panels/Panels.md
- Bitarf RI/Printing/Printing.md
The “insert here...” comments left in place and the string catalog reconstruction metadata indicate specific locations for filling in content. Prompts are saved as text to document functionality, UI, packet fields for classic device models, constants, measured values, and compatibility behaviors.
Recommended reconstruction order:
- Core hardware profile and wire protocol.
- Dot-matrix work segments and stream throttling.
- CoreBluetooth adapter, response parsing, and device status.
- Document defaults, configuration tables, print UI, and Traditional Chinese text.
- Create separate tests and verify packets, CRC, density, paper feed, and long-document throttling on actual devices.
