run compiled (*.go) file from command line?

Is it possible to run a compiled file from the command line with "guile"? I'm assuming that it was compiled with something like: guild compile --output=whatever.go whatever.scm Or is it possible to just make an executable file out of "whatever.scm"? Thx

getting to know the FFI ...

I figured that I would try and do something simple-ish to see how well I understood the FFI. I found this GTK tutorial, written in Chez Scheme: https://github.com/jhidding/lyonesse/blob/master/gtk-tutorial/window.scm I just tried to replace the Chez FFI calls with Guile FFI calls. I'm not sure how

Guile dynamic FFI, C function expecting pointer

broken link on "Learn" page

There is a broken link to the "Internet Scheme Repository" on the "Learn" page of the GNU Guile website: https://www.gnu.org/software/guile/learn/ I didn't see a contact email on the website, but I figured that someone here might know someone that ran the website ... if not, my apologies.

is there a way to serialize hash tables?

I have a big-ish blob of key-value pairs that I would like to not have to store as text and then convert to a hashtable when I am filtering my data. Right now I am saving it as an alist and then converting back to a hashtable using "alist->hashtable" from SRFI 69. I was just hoping that there was

Somehow I have got this "thunk" thing wrong.

I wanted to store a thunk in a hashtable so that I could look up its key and then run it later. Something like this: #! /usr/bin/guile !# (use-modules (ice-9 hash-table)) (define stuff (alist->hash-table '((a . (lambda () (display "event a\n"))) (b . (lambda () (display "event b\n")))

Python's pdb module

Is there something in Guile that is similar to Python's "pdb" module? For instance, sometimes I find it helpful to pause right before something bad happens with: #!/usr/bin/env python3 import pdb; pdb.set_trace() some_function_that_is_going_to_fail_miserably()

So ... building the git version of Guile seems different, I looked around for an INSTALLING file, and it isn't there (and neither is 'configure') ... any hints?
