macirb does not eval UTF-String

[dev@…]

$ echo 'p "Rübe"' | macirb
p "Rübe"
SyntaxError: (irb):1: unterminated string meets end of file
	from core:in `eval:'
	from core:in `evaluate:'

confirmed

irb cannot handle multibyte strings because of a limitation of our readline implementation (libedit), but here it seems to be a different problem (the string is given as an argument and not from stdin).

Replying to lsansonetti@…:

irb cannot handle multibyte strings because of a limitation of our readline implementation (libedit), but here it seems to be a different problem (the string is given as an argument and not from stdin).

but typing it in macirb directly gives the same result:

$ macirb
irb(main):001:0> p "Rübe"
SyntaxError: (irb):1: unterminated string meets end of file
	from core:in `eval:'
	from core:in `evaluate:

I cannot even enter some letters - I get only questionmarks. Why do you not just compile MacRuby with the real "readline" instead of "libedit", which is buggy and missing a lot of features?

[lsansonetti@…]

We do use libedit because it's what's available on Mac OS X by default. Readline isn't bundled because of licensing issues. We are aware that libedit misses functionality (the biggest problem is certainly missing support for multibyte characters). But this isn't a MacRuby problem, you should report this to Apple using  http://bugreporter.apple.com. Alternatively, in trunk (future 0.7) there is a new irb implementation (called DietRB) and it is possible to plug some pure-ruby readline code on top of it, fixing the multibyte input problems.

Just checked, and this does work with the 0.7 release. This ticket can be closed. % echo 'p "Rübe"' | macirb "Rübe" => "Rübe"

Thanks.
