Hi all,
I was trying to copy a vector slice into another destructively using
vector-move-(left!|right!) and came across a bug. If you try to fill
the whole of the destination vector, you will get an error. This
happens with both vector-move-left! and vector-move-right!, and it
does not matter if
Hey guilers,
If you run (exit) at the repl, it is caught, and any after-thunks from
dynamic-wind will be called when you continue with ,q . However, in a
guile script, it is not an error, and the after-thunks are not
called.
$ cat Desktop/dynamic-wind-test.ss
#!r6rs
(import (rnrs))
Hello, Guilers
When using type specific equality predicates in guile, I've noticed
that they only test the type of an argument, if it has not already
decided that the answer is false. Working my way through all the
predicates given by the meta command ,a =\??$ we find
GNU Guile 2.0.0.147-e309f
Hello Guilers,
Over on Racket Users, Marco Maggi points out that ASSERT should return
the value of the expression if it is true[0][1]. I have attached a
simple patch to fix this behaviour in guile.
Regards,
Ian
