Re: library vs define-module issue

[Zelphir Kaltstahl]

Thanks John! This solved the problem. I now have it like this:

~~~~START~~~~
(library (geometry (0 0 1))
  (export point
          make-point
          get-point-label
          get-point-coords
          vector->point)
  (import
    (rnrs base)
    (only (guile) lambda*)
    ;; structs
    (srfi srfi-9)
    (srfi srfi-9 gnu)
    ;; fold and list operations
    (srfi srfi-1)))

... (other code) ...
~~~~~END~~~~~

and I can import that just fine.

Are all forms, which are usually available when using (define-module
...) exported in the import set (guile)?

If not, where would I look for them?

Using (help identifier) inside geiser helps. It shows me for example:

~~~~START~~~~
scheme@(guile-user)> (help define)
No documentation found for:
(rnrs base): define
~~~~~END~~~~~

Which tells me what I would need to import when using (library ...).

Best regards,
Zelphir
