cl-forth: Forth 2012 Standard in CL
TL;DR
CL-Forth is a Common Lisp implementation of the Forth 2012 Standard, compatible with several Lisp environments. It currently has limited support in ECL due to unresolved test failures.
✦ Why It Matters
Explore CL-Forth today to leverage Forth's capabilities within your Common Lisp projects.
Key Takeaways
- Install CL-Forth using QuickLisp for easy library management.
- Utilize the experimental optimizer to improve performance in your applications.
- Create standalone Forth applications that run directly from the command line.
- Explore the foreign function interface to integrate external libraries.
Full Summary
CL-Forth implements the Forth 2012 Standard using Common Lisp, ensuring compatibility with Clozure Common Lisp, SBCL, and LispWorks, among others. It runs on macOS, Linux, and Windows, and is available under the MIT License.
The implementation includes an experimental optimizer that can enhance performance by reducing the size of generated object code and speeding up execution, particularly under SBCL. Users can create standalone applications that launch directly into the Forth interpreter.
However, certain optional features of the Forth standard, such as the Block word set and specific keyboard handling words, are not implemented. The system also includes a foreign function interface (FFI) for integrating with external libraries, expanding its usability for developers.
