crForth

UNFINISHED: Yet Another Forth implimentation, In C

This is not a Forth for your embeded system. This is a Forth intergrated into Raylib. It will only work on systems where Raylib can be found.

Core Libraries Used:

• Raylib 5.5, linked via pkg-config.
• minunit, source added to project.
• klib, source added to project.

Project Goals:

• Pass Forth Standard Tests: https://github.com/gerryjackson/forth2012-test-suite/tree/master
• Run all Raylib Examples.
• Be compatable with packages found on: http://theforth.net/packages

Linking Raylib

This project uses pkg-config to link to Raylib. If you encounter issues where Raylib functions (e.g., EndDrawing, DrawText) aren't found during linking, it may be due to pkg-config not correctly detecting your Raylib installation—especially if you built Raylib from source.

You can check if pkg-config knows about Raylib by running:

pkg-config --cflags raylib

crForth Features

• Runs on a stream.

C Helper Functions

These functions work with data pointer defined in the word metadata.

• DoForthString - Runs DoForth with the ForthWord->data as the input stream and the current Kernel State.
• Variable - Returns the memmory address for WorldMetadata->data
• Nothing - Does nothing.

To Fix:

• BASE
• LOOPS!
  • ✅ DO LOOP
  • BEGIN WHILE REPEAT
• CoreForth is loading the CoreWords from a path relative to the path used to run crForth. It should be either included into the binary, or relative to the binary location, not the calling location.
• need TYPE
• Finish ' tick
  • when run inside a compiled definition, it should return the XT of the word after the definition. (Test tick_compile_mode checks for this.)
• need EXECUTE
• need? REFILL
• need? SOURCE
