re: macroexpand

there are two macro-expansions available:

macroexpand-1 or macroexpand-all

a macro is a code-rewriter or template engine

think of it like a super-powerful search-and-replace for code

kind of how the C language has a pre-processor which handles #define statements

Clojure’s macros are evaluated at “compile” time

and they re-write your code (usually to a longer version)

macros can generate code that contains. … other macros

this re-writing (or expansion) is recursive

but eventually you will hit something truly “primitive” like a function

macroexpand-1 only does 1 level of macro rewriting

macroexpand-all will go all the way down the rabbit hole and do all of the recursive expansion till you ground out

cool, spread the word this is the best channel to hang out in for Miami Clojure Meetup.

there are lots of other interesting channels, mainly for asking questions about Clojure (#C03S1KBA2), ClojureScript (#C03S1L9DN) setting up Emacs and Cider #C099W16KZ and #C0617A8PQ respectively for Clojure/ClojureScript development etc.

there’s also #C03RZRRMP and #C05006WDW which may be of interest...

oh and #C053PTJE6 which are a great way to get constructive criticism

yay! :simple_smile:
