Show HN: A Common Lisp implementation in development
2 days ago (savannah.nongnu.org)
I've been working on this for a couple years.
Implementation of the standard is still not complete, but in my opinion breakpoints and stepping work quite well! Support for loading systems with ASDF is near.
Let me know if you like it! Support on Patreon or Liberapay is much appreciated
The implementation looks easier to handle than e.g. ECL or CLISP, cool.
Do you have an estimate how complete your implementation is?
How does the performance compare with e.g. ECL or CLISP?
Did you run conformity tests, e.g. with https://gitlab.common-lisp.net/ansi-test/ansi-test?
Based on the number of symbols implemented, I'd say that more than three quarters of the standard are done, almost enough to load a system with ASDF.
Performance seems on par with clisp, but important optimizations are yet to be done, for example my program is still single-threaded
That's amazing, thanks.
Can you please share more background information about the project, in particular why you wanted to take on this huge challenge, and why you didn't just start from an existing implementation, and why you chose C as the implementation language? Do you assume that you can still use the same GC with the addition of multi-threading?

You can support my implementation on Patreon (https://www.patreon.com/andreamonaco), even subscribing to the free tier is helpful. Thanks everyone!
What are the pros and cons of this vs other Common Lisp implementations such as clisp and others?
My implementation builds very easily, like 20 seconds on my laptop. More importantly, debugging and stepping work very well

About the same time on my old EliteBook 2530p.
