@abcdw I think this is a very good idea, although I would prefer the focus be more on R7RS standard Scheme more than Guile. And it will be very difficult since Scheme is not used often enough in industry.

I have been using Scheme myself to create a medium-scale application, and I have already started writing a series of blog posts about my experience, and what I have learned. I am still in the process of revising them, but I hope to publish them in the first week October, hopefully.

The thing is, I still have relatively little experience with Scheme, only about a year using it for real software engineering. So my blog posts are not really about "best practices," so much as they are about discussing the possible pros and cons of various techniques to solve problems. I have upcoming articles on the pros and cons of:

-

Scheme "environment" objects, and how the "load" procedure works across various Scheme implementations

Scheme "parameter" objects for dependency injection

Scheme monadic programming, including a discussion of SRFI 247: "Syntactic Monads"

I would also love to write articles about unit testing and type checking, but that will take some time.

@shegeley you should probably install the developer build of Guile, something like "guile-3.0-dev" in the Debian (and derivative) Linux repositories.

Then what I do is actually run the whole Guile interpreter in GDB. Here is a script I use, I call it "gdb-guile.sh":

#! /bin/sh
gdb \
  -ex 'handle SIGXCPU nostop' \
  -ex 'handle SIGPWR nostop' \
  -ex 'run' \
  --args \
    guile "${@}";

To run it, I simply type

./gdb-guile.sh my-program.scm --args=to --my=program

If you use Emacs and Geiser, you can try setting the "geiser-guile-binary" variable to the full path of "gdb-guile.sh", I ususally set it in my ".dir-locals.el".

@shegeley new reply to a couple weeks old post, but .....depending on what you want to do you can run more or less full guile programs under GDB's extension system, however there are parts, for example calling DISPLAY that don't work. Multithreading is difficult. Any TUI libraries are non-starters (that I know!) like using guile-ncurses. I've got a guile extension that I've been on and off working on for several years now, and have run up against a number of limitations in the API, but I've still found it to be quite useful. Here's a link to the only other guile extension I know of, indeed the only guile extension published out in the wild, I thankfully forked it before it was taken private again https://github.com/dtpeters/gheap-jemalloc
You might reach out to the author and see what his experiences were, I'd be very curious to hear what he says if you are able to make that connection.
