(length all-python-packages)

(length all-python-packages)

[jgart]

Hi,

How can I list how many Python packages we currently have in master?

What Guix APIs do you suggest that I hook into to determine this?

How about this:

  (use-modules (gnu packages)
               (guix build-system pyproject)
               (guix build-system python)
               (guix packages))

  (fold-packages (lambda (pkg count)
                   (+ 1 count))
                 0
                 #:select?
                 (lambda (pkg)
                   (and (not (hidden-package? pkg))
                        (member (package-build-system pkg)
                                (list pyproject-build-system
                                      python-build-system)))))

For me, this returns "2749".

more crudely, I tried this on the command line:
   ./pre-inst-env guix package -A ^python | wc
which returns 2165, or
   ./pre-inst-env guix package -A ^python- | wc
which excludes python2-packages and returns 2140, or
   ./pre-inst-env guix package -A ^python- | awk '{print $1}' | uniq | wc
which excludes duplicate package versions and returns 2091.

It looks like we have a lot of python packages that do not admit it
in their name :)

Andreas and paren,

Thanks for the replies and examples. Much appreciated!

I imagine this does not include python packages like jrnl, khal, clikan, t-todo-manager, gajim etc?

Yep.

If you need more reliable numbers, use ('s code snippet: there 
will be a handful of false negatives (e.g., packages written in 
Python that prefer to use Makefiles, or that mix phases from 
different build systems) but that number will be insignificant.

Kind regards,
