<AwesomeAdam54321>How can I use ice-9 open-pipe* to run a subprocess and capture it's output? I can't find any examples online

<iyzsong>AwesomeAdam54321: hey, in the source of guix, there are many examples

<AwesomeAdam54321>iyzsong: Thanks

<AwesomeAdam54321>What is allowed as datums in a case statement?

<AwesomeAdam54321>I get an invalid clause error when I try to use strings for datums

<daviid>AwesomeAdam54321: symbols and numbers

<AwesomeAdam54321>daviid: How could I do a case statement with strings? or would I just have to use when statements?

<daviid>use string->symbol

<daviid>(case (string->symbol "hello") ((hello) "world"))

<flatwhatson>AwesomeAdam54321: not when statements, probably a cond

<flatwhatson>(cond ((equal? val "hello") "world"))

<AwesomeAdam54321>daviid: Is there a reason case statements only accept symbols and numbers?

<daviid>AwesomeAdam54321: did you read the case statement in the guile manual?

<daviid>or ny scheme manual

<daviid>any

<AwesomeAdam54321>daviid: I read the guile manual online, but I didn't know what a datum exactly was from looking at it

<daviid>ok, it says First, key is evaluated. The result of this evaluation is compared against all datum values using eqv?.

<daviid>strings can't be compared using eqv?

<AwesomeAdam54321>my mistake

<daviid>no problem, it's kind of a faq, soyou're not alone :)

<lloda>guile doesn't check for gperf at configure time

<daviid>lloda: i thought one of us fixed that, i even thought it was you? :) but i think there is a patch somewhere, not sure

<daviid>hum, maybe i am wrong, i can't find any trace of any gperf/configure recent discussion(s) in user/devel ml ... and our channels logs aren't searchable at the moment

<cwebber>hello hello

<cwebber>a thought:

<cwebber>I've recently discovered just how extremely much (default-optimization-level 1) makes debugging guile code easier

<cwebber>I'm just thinking out loud...

<cwebber>I wonder if it would be a good idea to add a config flag to my ppackage

<cwebber>so i could do ./configure --debugable or something

<cwebber>andm aybe it would compile using the -O 1 flag

<Zambyte>Hi, I'm trying to play around with some portable libraries, but I'm having trouble. For a test I'm trying to run SRFI-78 from chez-srfi, which has a compat.guile.sls file, but won't load for me. This gives a "no code found for module (srfi srfi-78)" error for me, not sure why or what to do differently: `git clone https://github.com/arcfide/chez-srfi srfi && GUILE_LOAD_PATH="$PWD:$GUILE_LOAD_PATH" guile -c "(import (srfi :78))"`. Anyone

<Zambyte>have any suggestions?

<Zambyte>I've also tried with `-x .sls` on guile, no luck

<jab>cwebber: how do you debug guile programs? Debugging elisp programs is awesome in comparison (my opinion)

<flatwhatson>jab: there's a full set of tracing & breakpoint tools available in the guile repl

<flatwhatson>plus the `pk' function is very useful to hack in some "printf" debugging

<flatwhatson>but as with C, the optimizer might inline stuff which makes stepping through your program less useful

<flatwhatson>some better emacs integration would be nice

<dsmith-work>flatwhatson: Have you tried geiser? (Note: haven't used it in a while)

<dsmith-work>sneek: geiser?

<sneek>I could be wrong, but geiser is git clone http://git.hacks-galore.org/jao/geiser.git

<dsmith-work>Awww.

<jao>sneek is very wrong
