Goals

• Based on Vintage/Classic Basic
• Creative programming primitives: Drawing & Sound
• Inspiration: Vintage Basic, Atari Microsoft Basic, and Quite Basic
• Line-based interpreter: i.e. every line is a syntactally complete statement

Architecture

• Line (string) => Lexer => [] Tokens => Parser => AST
• Expressions are precompiled to JavaScript expressions
• Runtime library basic.js handles execution, debugging, and context
• AST nodes run themsleves

TODO

• Strinct expression parsing (e.g. 3 XX should not be acceptable)
• Nonsense errors: SQRT, a[0]
• pass rgb array to plot
• implement mouse getpos
• test/fix repl
• should round plot calls
• don't queue keys while paused
