Over the last two years, my writing has been precisely as confusing as my thoughts, go figure. I kept trying to understand why I wanted to use Common Lisp even though it was a pain in the ass. I kept trying to justify why quitting music and selling my equipment was what I wanted to do. There was a lot of push/pull that just made no sense. https://smashedtoatoms.com/posts/2021/03/sharpsign-plus-reader-macros/ Sat, 13 Mar 2021 14:07:08 -0700 https://smashedtoatoms.com/posts/2021/03/sharpsign-plus-reader-macros/ WTF does #+(or) mean? They’re called reader macros. Reader macros in Common Lisp are a read-time feature that lets you do a pre-compile condition check. The #+ reader macro checks for a feature, and if it succeeds, then the S expression following it is evaluated. If not, the code never even gets passed to the compiler. It is as if it never existed. They’re kinda like the ifdef and ifndef macros in C/C++.
