Re: Should Guix support writing CLI Common Lisp scripts? (Think Roswell)

[Charles <charles.b.jackson@protonmail.com>]

Hello. I have done scripts exactly as John describe before. I think this way is fine for making common lisp scripts on guix; that command line you shared can be put in a file and run as a shell script, or even put into a package. 

I think what Jgart is asking for is a program that may or may not be a part of gnu guix, but certainly depends on it. This program will be able to run roswell scripts with 100% compatibility using guix instead of roswell for loading systems. I'm not too sure how roswell knows which system to load or which common lisp implementation to use for a given script.

The purpose of this program would be to use guix's common lisp implementations and systems for roswell scripts. As I understand it, running roswell on a guix system will result in roswell downloading and installing it's own common lisp implementation and loading systems from quicklisp.

Do you mean using a particular hashbang as well? I haven't done that but my simplistic usage is quick and easy for me. For example, I like to have some CL scripts I use for file processing that lives as a single .lisp file. To run it I just do: guix shell sbcl sbcl-cl-csv unoconv -- sbcl --load myscript.lisp ~/Downloads/*.xlsx where I can include the compiler/interpreters sbcl, needed library, and an external tool that is called by the script for pre-processing. Works great, and of course instantly after the first caching. This could be combined with a manifest, version/channel pinning, making my script a package in a channel, guix.scm file, and so on, to make it more reproducible. But for me this is already super handy and easy, just one line. John
