I've put in some changes to io: - interface to query existing layers - move various things around
Not much yet. But:
IO does currently translates to/from utf8 by default, so we need some tweaking here:
Proposal:
- create a new string layer that does this {en,de}coding
- change the prototypes of PIO_Read to return a STRING*
- change the prototypes of PIO_Write to get a STRING*
- layer push and pop functions for ParrotIO
- we would need some means to define the default layer
(i.e. which PIOs do utf8 by default, if any)Strings that don't go through the string layer get a new flag like encoding_raw_bytes or such denoting a byte encoded buffer.
Comments welcome, leo
