if your searching especially for info about portable Scheme code,
following places might help:
- slib has an
.init file for all supported Schemes with some compatibility
code; less common procedures, but rather meta data; could still
be equally interesting for the implementation-metadata
- the r7rs-benchmarks
repo has some src/xxx-prelude.scm files, this time more like
Scheme-specific procedures for a common layer
- Oleg Kiselyov has some common prelude procedures for various
Schemes here; not
exactly up-to-date (2004), but hey: it's from Oleg
- I also once bookmarked the prelude procedures in this
blog post, but I assume that you could find many of the
procedures there in SRFI-1.
- If you like if-let, when-let, push, ... and some more CLisms,
they are here.
- If you're searching more generally for Scheme best practices,
I don't have any links; I like to read through the SRFI
implementations, because that's often so beautiful code.
