Plain

A Kotlin Development environment

Plain and Simple, fast and no headache

A file is the most important abstraction
The project of a file is always where the git root is
Opening a file opens the project of that file
Fast to edit files (sub two mili second file open and ready cold start)
One instance open, interact via IPC possible, for example commands open via IPC the file in the already running process.
File traversal/search/opening should be possible via UI, CLI (IPC)
Max FPS, egui implementation for the UI
One binary (mise and pitch fork bundled into it), config at the root where .git

Environment is reproduceable and depends on the open file -> .kt, config at the git root -> JVM target with version 21 -> install 21 if not installed and use for this project (use mise: https://mise.jdx.dev/)
Doing something with CLI versus UI should not change the behaviour
Use pitch fork for running dependencies (https://pitchfork.en.dev/)

Refactor via right click menu choose file -> function/class etc.
Debug via right click menu or via cli which will let the user choose file -> line -> set break points
Select functions via select or cli via name to extract into play ground, that has the same environment and libraries loaded but has a different main file.
