Range problems

[James Cunningham-5]

Hello. I'm not much of a programmer -- more of a budding economist,  
really -- but Io seems nice. I have a few questions, in particular  
about the Range addon, which seems rather broken. I pulled the Git  
sources the other day; this regards version 20080120.

First -- Range slice ignores the increment parameter. Second -- a  
Range whose end point won't be exactly hit by the increment (ie,  
Ranges for which (end - start) % increment != 0) will result in an  
infinite loop when iterated over. Ranges with ending values greater  
than starting values also result in an infinite loop, instead of  
iterating backwards.

Things that don't work:

1 to(10) asList slice(2, 8, 2) // rather bizarrely, returns list(3, 4,  
5, 6, 7, 8, 9, 10)
Range clone setRange(1, 10, 2) asList // infinite loop
Range clone setRange(10, 1, 1) asList // infinite loop

The first is easy enough to go into and fix, but I can make neither  
hide nor hair out of the C code for Range.

Is there some place to submit a bug report? The "issues" portion of  
the main site seems like the best place for such a thing, but it's not  
working now. The download link advertises a version with a later date  
than the one I pulled, but trying to download it results in the  
message "This repo is too large to generate a tarball. Please file a  
bug report."

Finally -- I see that there have been requests for more working  
example code -- and I agree that this would be nice. I mean this as a  
suggestion more than a criticism, but it *is* sort discouraging to  
find all sorts of neat examples strewn over the internet (operator  
overloading, Scheme-style let, etc) only to find that very, very  
little of it still works.

Regardless, Io is fun, thanks.

Best,
James

Your first example, use this instead:

1 toBy(10, 2) slice(2, 8)

The second is a known issue, and I just have not had time over the  
last year to fix it, and my time is not looking good in the  
foreseeable future.

When I try that, I get:

Io> 1 toBy(10, 2) slice(2, 8)
==> list(5, 7, 9, 11, 13, 15, 17)

Which doesn't seem quite right. Quite possibly I'm missing something,  
of course.

Cool, thank you.

Err, make that slice(1, 4) (divide by your increment operator). Just  
tested, returns list(3, 5, 7, 9) which is correct. Not sure why you  
were getting things out of order.

Its seems problem on web site.
When I try to download
http://github.com/stevedekorte/io/tarball/2008.03.30
I got message "This repo is too large to generate a tarball. Please file
a bug report"

Thanks for the report - I've reported it to github and they said it  
will be fixed soon.
