Practical Common Lisp VS Crystal (programming language)

There are a bunch of things to learn from Lisp: * list processing -> model data as lists and process those * list processing applied to Lisp -> model programs as lists and process those -> EVAL and COMPILE * EVAL, the interpreter as a Lisp program * write programs to process programs -> code generators, macros, ... * write programs in a more declarative way -> a code generator transforms the description into... - Source: Hacker News / 3 days ago

In respect to Common Lisp, you could look into "Common Lisp Recipes" by Weitz[2], and "Practical Common Lisp" by Seibel[1]. These are industrial-strength systems which were used to built large airline reservation systems. Scheme is in a way more minimalist and Schemes are not as large, but this might also be give an erroneous impression because they build on the enormous experience with Common Lisp and have boiled... - Source: Hacker News / 14 days ago

Not exactly what you asked for but, if you have time, I would recommend looking at Practical Common Lisp: https://gigamonkeys.com/book/ And also this blog post (which is a much smaller time commitment): https://mikelevins.github.io/posts/2020-12-18-repl-driven/. - Source: Hacker News / 5 months ago

If someone is considering learning CL effectively, take this piece of advice: use Emacs. You might think that it's an outdated piece of shit, maybe you hate RMS with a passion or whatever. But make yourself a favour and use it at least for the month that will take you to go through a manual like this or Practical Common Lisp or several others. Just install SBCL, QuickLisp, Emacs and SLIME (or Sly, that is a more... - Source: Hacker News / 7 months ago

And Practical Common Lisp, another popular one on HN. The domain name took me by surprised and I struggled to remember why it seemed so familiar; it turns out that PCL can be found in its entirety here, and I had used it years ago to learn CL: https://gigamonkeys.com/book. - Source: Hacker News / 9 months ago

I like the first code example on https://crystal-lang.org

Obviously as an interpreted language, it's never going to be as fast as something like C, Rust, or Go. Traditionally the ruby maintainers have not designed or optimized for pure speed, but that is changing, and the language is definitely faster these days compared to a decade ago. If you like the ruby syntax/language but want the speed of a compiled language, it's also worth checking out Crystal[^1]. It's mostly... - Source: Hacker News / 5 months ago

Crystal is a nice language that's not only simple to read and write but performs very well too. And the documentation is amazing as well. Source: 5 months ago

Ruby is a super fun scripting language. I much prefer it to python when I need something with a little more "ooomph" than bash. It's just...nice...to write in. Ruby performance has come a long way in the last decade as well. There's libraries for pretty much everything. My modern programming toolkit is basically golang + ruby + bash and I am never left wanting. I do find Crystal (https://crystal-lang.org/) really... - Source: Hacker News / 5 months ago
