Refactoring, smart navigation and code assistance for CodeMirror
Reflector is a CodeMirror extension that allows language packages to provide refactoring, code navigation and linting features.
It is a promising proof-of-concept but not a stable API you should rely on and the claimed features aren't ready to use
Demo (proof of concept only)
- rename variable
- go to definition
- find usages
- highlight undefined variable
- highlight unused function
- and more....
There are 2 pieces: the Reflector extension (this repository) and some additional nodeProps the Lezer LRParser grammar must be tagged with in order to use some of the refactoring features. These node props provide Reflector with some understanding of the structure of the language---particularly the relationships between scopes, uses and definitions of identifiers.
Reflector uses core CodeMirror features to drive the cursor or selection to other parts of the file when you use navigation or refactoring features.
It plugs into CodeMirror's Lint extension and uses it to display problems and suggestions it has found. It also provides Autocomplete suggestions using the identifiers that are in scope.
Finally, it provides an additional set of editing commands and a Keymap that makes them available in the editor.
This repository contains an example language definition which I'm using to explore and demonstrate the features I'm trying to implement. The other main folder is the source code, which implements the refactoring and navigation features.
