hey guys. could someone please write a macro for me pretty please. I just want something that's analogous to this emacs lisp. http://ix.io/1LhA ie.e it should run some code but first pass the code through another function
<libertyprime>
run is apply, pretty much. and try is an emacs builtin that runs the code without throwing an exception if it errors
<libertyprime>
essentially i just need something which i can wrap around some syntax form and run a side effect using the raw code, then pass the raw code through transparently

<greghendershott>
Is `run` a function or another macro? What's its definition?
<greghendershott>
Often macros with a "body" are simply sugar for a function that takes a thunk.
<greghendershott>
In that case it's usually a good idea to write the plain old function first. In this case, let's say (define (call-with-effect proc thunk) __do stuff and call thunk_)`.
<greghendershott>
Having written the `call-with-effect` plain old function, then a `with-effect` macro is pretty much a one-liner.
<greghendershott>
BTW `try` isn't a function defined in Emacs 25.2. What you describe sounds a lot like `ignore-errors`.
