spec(developer): LDML Keyboard Designer 😹

[mcdurdin]

Introduction

This is a holding issue for the Keyman Developer LDML keyboard designer. We'll be filling this in as we complete planning and design.

Objective: build a tool that allows intuitive and visual editing of LDML keyboards for all platforms.

There are many parts to this, including visual editors, transform editors, testing interfaces. The intent is to build this in Typescript in such a way that it can be integrated into Keyman Developer but also in the future run as a standalone web app.

Adding some overall design points here , from 2024-March discussion:

Major Areas:

• Repertoire Builder
  • pulls from SLDR/CLDR where possible for exemplars
  • choose/augment from char map
  • Strings, not codepoints
• Keybag
  • Not 1:1 with repertoire: may be many more in repertoire, especially for touch
• Layout
  • Hardware or touch
  • may start with hardware, then copy to touch
• Transforms
• XML editor
