plyn is a VS Code and Cursor extension for ***plain, a spec-driven programming language developed and maintained by *codeplain.
It adds first-class language support for ***plain, so you can edit, navigate, and refactor ***plain code with confidence.
Features
The extension implements:
Syntax highlighting that follows the ***plain specification and highlights keywords, types, literals, comments, and operators for clear readability.
Rename concept support that lets you safely rename a concept across the workspace, keeping definitions and references in sync.
Go to definition and go to references so you can jump to where a concept is declared and see where it is used.
Plain file icon theme to make .plain files easy to spot in the explorer.
Usage
Open any .plain file to activate the language features and syntax highlighting.
Use F12 for Go to Definition and Shift+F12 for Go to References.
Use F2 to rename a concept across the project. The extension updates all
matching references for you.
Release Notes
