I began learning Common Lisp (CL) from the Common Lisp HyperSpec (CLHS): https://www.lispworks.com/documentation/HyperSpec/Front/Contents.htm When I began learning CL about two decades ago, I did not know of any other source, so CLHS was my only source back then and I think it has served me well. A popular recommendation these days is Practical Common Lisp (by Peter Seibel): https://gigamonkeys.com/book/. - Source: Hacker News / 4 months ago

> So it's really pick your poison; either the child controls the call, at the risk of doing it wrong or not at all, or it doesn't but then certain things become impossible. CL lets you do both in various ways: the typical way to define a constructor is an :AFTER method that just sets the slots (fields in other languages) of the object and having a lot of behavior in constructors is unusual. You can also define an... - Source: Hacker News / about 1 year ago

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 / about 1 year ago

Paul Graham's https://paulgraham.com/onlisp.html is a whole book about it that really helped it click for me. The challenge with the syntax is that there is no syntax. Work that we're used to offloading to syntax is instead carried by your brain. - Source: Hacker News / 9 months ago

BTW, if you're interested in learning more about Lisp macros, Paul Graham's book about advanced Lisp programming, On Lisp, covers the topic pretty extensively and it's freely downloadable from his website: Book description: https://paulgraham.com/onlisp.html Download page: https://paulgraham.com/onlisptext.html. - Source: Hacker News / 10 months ago
