Hello, I am looking for a workflow advice. I am using Emacs with Geiser.
I am trying to write couple of procedures that are very imperative and I am not
sure how to do that nicely in REPL. For example, let us assume I have a
procedure of following character:
(define (foo)
(let* ((x (bar-x))
(y (bar-y x)))
(step1 x)
(step2 y)
(step3 x y)
...))
Now, each step can be a procedure call, of just few expressions. Now I would
like to write the additional steps while utilizing REPL somehow, but I am not
sure what is an efficient way.
Can I somehow run just to the `...' and get a REPL there so that I could C-x C-e
the steps within the let* (for x and y)? Should I just (temporarily)
(define x (bar-x))
(define y (bar-y x))
in the REPL so that I can use C-x C-e on the steps? I expect that to get messy
once the lets start nesting for example.
How do you do it? Are there any resources (blog posts, toots, videos, ...)
regarding guile developer's workflow? I did read few, and I (think I) know the
fundamentals of Geiser and the REPL, but I am straggling a bit in this case not
to fall back to the "normal" way of "write a function, run it whole against a
test". Since this is Scheme, and I *can* evaluate single expressions in the
procedure body, I would like to use that to my advantage. Somehow.
I realize this is a very open-ended question/email.
Have a nice day,
Tomas Volf
