<symbol><number>
(<symbols>)<number>

Setup oddities (dev)

1. Copy antlr4's cpp libs to ./libs/antlr4. (Please take care that the include folder points straight to the files not to antlr-runtime)
2. Copy antlr-4.8-complete.jar to ./thirdparty/antlr.
3. Generate parsers to ./libs/generated or use VSCode with the ANTLR extension.

Todo (Tentative)

• Grammar
  • Number shorthand
  • Loop statements
  • Shorthand segments
• Processing
  • Translate to bf
  • Execute results
