RE: set-current-module in .guile ?

["Walck, Scott" <walck@lvc.edu>]

I don't know how to use use-modules in this situation.  I'm not trying to load a module that has been prepared as a file.  I tried

(load "/usr/local/src/guile-scmutils/src/load.scm")
(use-modules generic-environment)

and

(load "/usr/local/src/guile-scmutils/src/load.scm")
(use-modules 'generic-environment)

and

(load "/usr/local/src/guile-scmutils/src/load.scm")
(use-modules (generic-environment))

in my .guile file, but none of them work.

Is there a way to take a module object like generic-environment and write it to a file that could be loaded with use-modules?

Hi Scott,
Can you for some reason not use use-modules?

Jon
