Hi Michael,
This could be another ABI calling problem. What architecture are you
running?

I'm having trouble with the NSString method
getLineStart:end:contentsEnd:forRange:. The range param at the end

First of all, the ordinary syntax can't be used because "end" is a
keyword, so I'm using the hash syntax.
I added cover methods to NSString to see what was happening. I made
two cover methods, one with the same signature as
getLineStart:end:contentsEnd:forRange: and one with the range param
first:
- (void)getLineStart2:(NSUInteger *)startIndex end:(NSUInteger *)
lineEndIndex contentsEnd:(NSUInteger *)contentsEndIndex forRange:
(NSRange)aRange
{
NSLog( @"getLineStartForRange startIndex: %d lineEndIndex: %d
contentsEndIndex: %d range: %@", *startIndex, *lineEndIndex,
*contentsEndIndex, NSStringFromRange(aRange));
[self getLineStart: startIndex end: lineEndIndex contentsEnd:
contentsEndIndex forRange: aRange];
}
- (void)getLineStart3:(NSRange)aRange end:(NSUInteger *)lineEndIndex
contentsEnd:(NSUInteger *)contentsEndIndex forIndex:(NSUInteger *)
startIndex
{
NSLog( @"getLineStartForRange startIndex: %d lineEndIndex: %d
contentsEndIndex: %d range: %@", *startIndex, *lineEndIndex,
*contentsEndIndex, NSStringFromRange(aRange));
[self getLineStart: startIndex end: lineEndIndex contentsEnd:
contentsEndIndex forRange: aRange];
}
When calling them, getLineStart3 with the range param as the first
param works fine, but getLineStart2 mangles the range:
endix = Pointer.new(:ulong_long)
conix = Pointer.new(:ulong_long)
ix = Pointer.new(:ulong_long)
ix[0] = 5
conix[0] = 6
endix[0] = 7
puts "selectedRange: #{selectedRange.inspect}"
@diagramCode.getLineStart3(selectedRange, :end =>
endix, :contentsEnd => conix, :forIndex => ix)
puts "try old way"
ix[0] = 5
conix[0] = 6
endix[0] = 7
@diagramCode.getLineStart2(ix, :end => endix, :contentsEnd =>
conix, :forRange => selectedRange)
puts "ix: #{ix} endix: #{endix.inspect} conix: #{conix.inspect}"
selectedRange: #<NSRange location=3 length=0>

lineEndIndex: 7 contentsEndIndex: 6 range: {0, 4294995796}

Am I missing something obvious?
Thanks,
