Help using Ranges

Help using Ranges

[Zachary Kurmas]

Can someone point me to a more complete example of how to use ranges?  When I try to run the example from the documentation


#|kawa:1|# ("ABCDEFG" [1 by: 2 <: 7])

I get the error shown below.  Am I missing an include or something?


/dev/stdin:1:22: warning - no declaration seen for :
/dev/stdin:1:22: unbound location: :
        at gnu.mapping.SharedLocation.get(SharedLocation.java:22)
        at gnu.mapping.DynamicLocation.get(DynamicLocation.java:28)
        at atInteractiveLevel$1.run(stdin:1)
        at gnu.expr.ModuleExp.evalModule2(ModuleExp.java:317)

#|kawa:2|#

Thanks,

Zack

Strange - works for me:

$ kawa --version --
Kawa 3.1.1 (git describe: 3.1.1-62-gebcfcca29-dirty)
Copyright (C) 2020 Per Bothner
#|kawa:1|# ("ABCDEFG" [1 by: 2 <: 7])
BDF

Perhaps a very old (or otherwise-broken) version of Kawa?

It works for me too (also using Kawa version 3.1.1).  However, I get an
error similar to the one in the original message if I start kawa with
the --r7rs option, so perhaps something like that is what's happening in
the earlier case.

Per was right:  I had an old version.

I grabbed the latest .jar file from the FTP server (which is version 2.1) instead of getting the jar file from inside of kawa-3.1.1.zip.  (Doh!)

Thanks,

Zack
