Hi Alex, I took a short look and Guile config seems to do much more than only parsing command line arguments. It seems to be a more general thing for configuring any kind of program and different kinds of configurations? I think examples in the readme file for a few things one can do with it would be cool. Could you provide some basic example for command line arguments with Guile Config? (I am often guilty of not writing any readme for my own projects ^^', but I pledge improvement!) The ASCII art diagram is nice for getting an overview and I am sure it all makes sense when one looks a bit closer and maybe looks into some of the code as well. I could not understand, why this tool would itself write configuration files after reading configuration files one provides for it, nor what a codex really is, except that it is some kind of struct. Maybe this all has to do with Guix? Do I need Guix for Guile Config or is it intended to be used together with that? I've only once tried to install the Guix OS thingy (Guix SD?). It did not boot from USB. I could not install it on my machine and I could not find a working tutorial on how to install it. Since then I've not tried again, so I have no experience with Guix or the OS at all. I am still learning about the "Guile ways" of doing basic things (cooking recipe learning style, I guess :D). The two examples I've created with getopt-long and SRFI 37 are in my examples repository (https://gitlab.com/zelphir-kaltstahl-projects/guile-scheme-tutorials-and-examples/tree/dev/command-line-arguments). With the SRFI 37 example I am not sure if the global options hash table is a good idea, as I usually try to keep as little global state as possible. I am trying to figure out all the basic things, so that if some programming problem comes up, I could say "Oh, lets do that in Guile Scheme.", just as easily, as I could do it with for example Python. When I think of something I do in Python and then think: "But how would I do it in Guile Scheme?", I feel an urge to be able to. Knowing the basics will let me get to the meat of the problem, instead of on-the-fly having to improvise many things to get there. If anyone wants to, they can use it as tutorials or templates or whatever, although I am too lazy currently to make proper tutorials out of things. I try to keep the examples easy to understand for my own good too though. Thanks for the hint Alex, great to see the Guile ecosystem growing! I often see new release announcements on this mailing list and every piece of new tooling or libraries makes it a bit better. Previously having practiced some with Racket, I am used to suddenly discovering some library that unexpectedly already does what I want in an elegant way. I think it would be cool if Guile gets to the same level + more discoverable. Especially with stuff like fibers (which is still on my learning list) under its belt, it is very powerful. Guile Hall also seems to be going in the direction of creating something that can be used with package managers or a Guile packages specific manager (?). Regards, Zelphir
