There's also `features' from chicken.platform, in case you don't want to depend on the r7rs egg only for that. All the best. Mario -- http://parenteses.org/mario

I would need to decide based on minor versions. But thanks nonetheless, "chicken-5" seems not to be mentioned in the docu. Christian

CHICKEN version dependent expansion
Dear All,
I am trying to define a function depending on the version of CHICKEN. I was
thinking to use "cond-expand" for this purpose, but found no suitable feature
in the documentation (
http://wiki.call-cc.org/man/5/Extensions%20to%20the%20standard#cond-expand )
that could achieve this, only if a CHICKEN is currently expanding. R7RS
suggests such features (in Appendix B: ) and other Schemes such
as Guile (
https://www.gnu.org/software/guile/manual/html_node/SRFI_002d0.html#index-cond_002dexpand
) and Gauche (
https://practical-scheme.net/gauche/man/gauche-refe/Feature-conditional.html#index-cond_002dexpand
) provide such features. Did I miss something in the documentation, or is
there an alternative ("R5RS") way to do this?
Thank You
Christian
