I haven't been able to build a recent version, but if you cansharesome updated instructions, then I could perhaps help out with some occasional testing. I have only managed to build from the old commit fc0d7a9byupdating the current python-on-guile guix package locally.netlib is not included, you can test to add the python modulefileto a (language python module) directoryWhat's been working for me so far is only (load"path/to/file.py")and (load-compiled "path/to/file.go"). (use-modules (a b c)) did not work for me, except to load modules already shipped with python-on-guile repo; (language pythonmodulepython) etc.I have recently added much more of the python stdlib aka 3.7butnotall. Not sure what you mean by .scm file and .py fle when it comestobase64 using that module in scheme gives scheme@(guile-user)> (b64decode (b64encode "abc")) $2 = b'abc' scheme@(guile-user)> (b64decode (b64encode #(1 2 3))) $3 = b'\x01\x02\x03' Which return a bytevector if you want a string back you need to interpret the bytevector back to a stringIm getting weird results when trying to output the base64 representation of a string, take btest.py: #import sys import base64 def mybmethod(x): mybytes = bytes(x, "utf-8") encodedbytes = base64.b64encode(mybytes) myb64string = str(encodedbytes, "utf-8") return myb64string #print(myb64string) #mybmethod(sys.argv[1]) and assume btest.scm using it with: (add-to-load-path (dirname (current-filename))) (use-modules (language python module python)) (load "btest.py") (define-public (mybmethodscm cmdline) (display (mybmethod (cadr cmdline)))) With this it will not work to run the scheme file with guile -e mybmethodscm btest.scm dfasdf The error I got indicated that btest.py uses the bytes procedure from within python-on-guile instead of from the python3 base64 lib: ------------------- In/home/user1/VirtualHome/src/code_guile/python-on-guile-test/btest.scm:18:11 4 (mybmethodscm _) In btest.py: 10:584 3 (_ "dfasdf" . _) In oop/pf-objects.scm: 584:15 2 (create-object _ _) 567:11 1 (the-create-object _ _) In language/python/bytes.scm: 99:6 0 Exception thrown while printing backtrace: Unbound slot in object Error while printing exception. language/python/bytes.scm:99:6: Wrong number of arguments to #<procedure 7f2bab5d4560 at language/python/bytes.scm:92:0 (self) | (self s)> ------------------- For a moment though, I could run: guile -e mybmethodscm btest.scm dfasdf | rev | base64 -d | rev # gives: dfasdf which was also strange.modules are a bit difficult as I use the guile module systemandthepython modules are different.

I am using the guix package python-on-guile 0.1.0-3.00a51a2 -maybethats outdated? The simple things I have managed to do, are like: (add-to-load-path (dirname (current-filename))) (load-compiled python-test.go) where python-test.go is compiled with: guild compile python-test.py --output=python-test.go --from=python and contains simple things, like: f(s): a = s + 1 return a but if I add statements to python-test.py like: import netaddr def myfun(a) <something using netaddr> (netaddr is a module installed via: pip3 install --usernetaddr)I receive an error about not finding the module. I am able to add only the modules which exist in thepython-on-guilerepo, like: import sys import base64 but Im getting errors, for example Im not able to use thingsfromsys, like: sys.path.append(<somepath>) sys.path.insert(0, <somepath>) I was able to use some things from base64 but I only receivedweirdresults when converting between bytevectors and strings betweenthe.scm file and .py file. What works fine using python3 python-test.pydonot usually work when passing either a bytevector or string to thesamego-compiled file from the .scm file using the python-code. Notsurewhether there's a problem using python3 vs python2 here? Essentially, what Im looking for is how to proceed if I want tousemodules installed via the pip package manager from guile, andwhatpaths and imports I need to make, and how I might need to wrap them correctly in the scheme and python files to invoke a pip packageprocedurefrom guile.
