This is a 3.0-compatible version of Tosh, the text-based Scratch project editor.
This version is open-source, with a readable, modern codebase.
Dependencies
- Project player thanks to Nathan's Phosphorus
Forkphorus, as before - Uses Nearley for parsing. (Originally Tosh used a home-grown Earley parser for performance reasons; I've now rolled lots of perf improvements into Nearley :-))
- Uses my optimised lexer Moo
- Uses nearley-reverse for transforming Scratch AST into Tosh code (on load); this is the opposite of parsing, which happens on save/run
- Uses Nathan's v2 for views, model, undo, menus, etc
Current status
-
Load/save seems to work
-
Importing / compiling scripts is there, but needs extensive testing & improvement
-
Measuring scripts is fully implemented & tested (so we can "clean up" when saving to sb2)
-
Playing projects seems to work
-
No sprite management
-
No costume management (nor am I particularly interested in adding this!)
-
Highlighting almost works
-
Completion is in-progress but goodness it's a difficult problem
Future plans:
- A desktop version for Win/Mac based on my unreleased lightweight Electron clone
Running
git clone --recursive https://github.com/tjvr/tosh2

echo ';window.P = P' >> phosphorus/phosphorus.js
yarn
yarn grammar && yarn test
yarn startIf someone wants to set up browserify/babelify for bundling, that would be excellent
