Ah, yes, of course; vacation. =) I have no memory. Marshalling is hard. I've tried starting to write a BNF for it, just so we can have some kind of spec, based on the C code. It's not that simple, though. There are some things in the internals that I don't really understand, for example rb_generic_ivar_table(). Is this a table for immediate variables, or something completely different? Doing this based on the C code isn't really that hard for most cases, but what bugs me is that it's so hard to know if we've got all the corner cases. Line terminator is really not fun, no. But as far as I can find, right now the IOHandlerSeekable is the only place where this is an issue. Positions can be handled except for when we have to return raw offsets. Otherwise things get more complicated. -unix would be a really handy flag! Lovely. =) /O _______________________________________________ Jruby-devel mailing list Jruby-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/jruby-devel
