Subject: Behavior of (import ...) in R7RS define-library forms
Date: Fri, 5 Feb 2021 09:21:56 -0500 [thread overview]
Message-ID: <CAE8gMz07hWQ7oq7257ULDg35pQ=mpoC7hBCvskytsSMo4uwK2Q@mail.gmail.com> (raw)
I have two r7rs-style libraries, one of which depends on the other,
located in the following filesystem structure:
src/lib/shadchen-helpers.scm
src/lib/shadchen.scm
In principle, shadchen-helpers isn't useful on its own - it provides
some helper material for the shadchen library.
The library definitions look like this:
$ find src/ -iname "*.scm" | grep lib | xargs head -n 2
==> src/lib/shadchen-helpers.scm <==
(define-library
(lib shadchen-helpers)
==> src/lib/shadchen.scm <==
(define-library
(lib shadchen)
So if I start a repl like this:
$ java -jar lib/kawa.jar -Dkawa.import.path="./src/*.scm"
Kawa can find the libraries if I do an import:
#|kawa:1|# (import (lib shadchen-helpers))
The above works fine. However, in a fresh interpreter:
#|kawa:1|# (import (lib shadchen))
/home/toups/work/games/jmonkey3d-lacraw/src/lib/shadchen.scm:9:4:
unknown library (lib shadchen-helpers)
/home/toups/work/games/jmonkey3d-lacraw/src/lib/shadchen.scm:110:6:
warning - no declaration seen for pattern-bindings-equal?
/home/toups/work/games/jmonkey3d-lacraw/src/lib/shadchen.scm:117:6:
warning - no declaration seen for all-identifiers?
The import fails because the library reference to shadchen-helpers
fails to resolve. That reference in `shadchen.scm` looks like this:
(import (except (kawa base) match)
(kawa lib std_syntax)
(srfi 28)
(rnrs sorting (6))
(rnrs hashtables (6))
(lib shadchen-helpers))
I have noticed that importing shadchen-helpers at the repl first and
then importing shadchen works. I would guess because importing the
shadchen-helpers library compiles that library and then the import
form in the r7rs define-library can then find the compiled artifact.
But doesn't it make sense for the import form in shadchen to trigger
the compilation of shadchen-helpers so that it behaves the same as a
top-level import? Is there any way I can get this behavior? It seems
limiting to interactive development to have to have either a build
process or a script to import all libraries despite an explicit
dependency graph existing in the form of the import statements in the
library definitions?
I'm relatively new to Kawa and a little rusty in Java (long time
Schemer, though) so maybe I'm missing something.
