Re: [Scheme-reports] Checking implementation features and Scheme name?

| These comments are not too important, but I thought
| I'd share anyway.
| Reading the latest draft I realized that there is no
| standard way to obtain a list of all features (those
| used by cond-expand) declared/supported by an
| implementation. Chibi, Guile and Tinyscheme do keep
| a list in the *features* variable, but it doesn't seem
| to be standard. It would make sense in some situations
| to check/log/report features, maybe not knowing a
| complete list of possible features beforehand.
| Also, I think that there is no R7RS-standard way to
| obtain the name of the Scheme implementation if
| I don't already know a list of all implementations
| (suppose I have written benchmark or test of some
| kind; it wouldn't be able to write a log with the
| implementation's name).
SLIB provides functions for reporting just such information.
-- Function: slib:report-version
Displays the versions of SLIB and the underlying Scheme
implementation and the name of the operating system. An
unspecified value is returned.
(slib:report-version) => slib "3b3" on scm "5b1" on unix
-- Function: slib:report
Displays the information of `(slib:report-version)' followed by
almost all the information neccessary for submitting a problem
report. An unspecified value is returned.
| I suppose these issues do not bother most people --
| am I wrong?
SLIB requires each implementation to define
(scheme-implementation-type) to return a symbol naming the
Scheme-reports mailing list
