<euouae>I have this script to run tests on my project

<euouae> <https://termbin.com/wxbx>, why doesn't the "General Case" run?

<euouae>I'm also trying to run this <https://termbin.com/3job> from the command line with either `env GUILE_LOAD_PATH=. guile -e main -s foo.scm` or `-l foo.scm` but neither work

<euouae>I have a bar.scm with a define-module and a `message` variable. Why is this not working? I've also tried compiling it with guild but I get an error about message being potentially undefined

<apteryx>is there something like map that also provides the index of the item in the list?

<apteryx>ACTION reaches to a named let

<euouae>apteryx: there is for vector

<euouae>vector-for-each

<apteryx>ah; nice to know, thanks!

<euouae>apteryx: you're welcome

<dsmith>enzuru, Use ((= i 10)) instead of (= i 10)

<dsmith>sneek, later tell euouae Use ((= i 10)) instead of (= i 10)

<sneek>Got it.

<dsmith>enzuru, was meant for euouae

<ieugen>I am trying to learn guile while doing adventof code and I get an error message that does not help at all

<ieugen>running https://github.com/ieugen/adventofcode/blob/66acd57895d867f90ca16f1e5b68818bbe4bb2b1/an2023/01-trebuchet.scm#L236 gives me

<ieugen>ice-9/boot-9.scm:1676:22: In procedure raise-exception:

<ieugen>Value out of range 0 to< 4: 8

<ieugen>I am also finding emacs very unfriendly to work with ...

<Arsen>emacs' a bit of a steep learning curve, yeah

<Arsen>ieugen: your error happens because one of your start indices are outside the bounds of your string

<Arsen>try, for instance, (string-contains "abcd" "b" 5) in the repl

<ieugen>thank you Arsen: but is guile error reportin so "bad" ? I did a lot of coding in java and you get a wall of text but you can track the line that caused it

<ieugen>any way I can display the stack trace here ?

<Arsen>it does do that

<RhodiumToad>what other lines did you get in the backtrace?

<RhodiumToad>use a paste site

<Arsen>though, for some reason it printed:

<Arsen>In unknown file:

<Arsen> 0 (string-contains "nine" 4 8 #<undefined> #<undefined> #)

<Arsen>:(

<ieugen>ice-9/boot-9.scm:1676:22: In procedure raise-exception:

<ieugen>Value out of range 0 to< 4: 8

<ieugen>[Debugging level: 31]

<Arsen>hopefully (guile)Debugging can shed some light

<ieugen>this is all I get

<Arsen>hmm, which guile version is that

<ieugen>I dno't know how to debug - especially in Emacs - which is something new as well

<ieugen>* I do know how to debug - but not in Emacs

<Arsen>ah, I was running it directly. I don't recall exactly how geiser works

<Arsen>(geiser being the scheme integration for emacs)

<RhodiumToad>you might get more or better info by invoking guile as guile --debug

<ieugen>thanks - I made some progress

<ieugen>I am missing something like this for guile https://clojuredocs.org/clojure.core/when

<Arsen>guile does have when, (let ((x 5)) (when (= x 4) (display "foo\n")))

<ieugen>yes, but clojure when returns nil if condition is not true while guile returns unspecified

<ieugen>it's hard to find that through all the manual

<Arsen>well, the documentation for 'when'/'unless' defers to 'if', which states:

<Arsen> When ALTERNATE is omitted and the TEST evaluates to ‘#f’, the value

<Arsen> of the expression is not specified.

<ieugen>hence why I miss something like clojuredocs.org - it's very usefull - esp if you not familiar with functions

<ieugen>+ you get examples

<Arsen>ACTION shrugs

<Arsen>I can't say I've ever used or seen clojure docs

<ieugen>try the link above

<Arsen>I'm sure improvements to guile docs are welcome
