<apteryx>can I redefine a variable in a if branch?

<apteryx>via 'define' ?

<dsmith>apteryx, You can use let

<apteryx>yes; I wanted to avoid nested a level deeper. I've found I could put some check in the default argument of my procedure to the same effect

<graywolf>Is it possible to use (format) to print an alist in key = val format?

<dsmith>graywolf, I *think* so.

<graywolf>The best I figured out is ~:{~a = ~a~%~} but it needs (map (lambda (x) (list (car x) (cdr x))) a-lst) as an argument

<graywolf>I failed to figure that out

<dthompson>why not just for-each and print out each pair?

<dsmith>Yeah, I was going to say, something with ~{ might do it

<dthompson>that format string looks pretty gnarly imo

<graywolf>Before I did (list (cdr x) (car x)) it actually was ~:{~*~a = ~@*~a~%~} ... this minilanguage is suprisingly powerful

<graywolf>It is part of fairly long (format #f ...), so I wanted to do it inside the call

<graywolf>But I could split it out into two with for-each in the middle

<graywolf>It just feels like I am *this* close... :/

<dthompson>if your formats are getting that complicated you might want to grab one of those lispy dsls for formatting

<dthompson>ACTION does not like 'format'

<dsmith>Pretty sure it's inherited from Common Lisp

<dsmith>That reminds me. There was something not quite right in the tranlations to Scheme. The way #f and '() are differnet.
