New IO implementation needs testing

[Abdulaziz Ghuloum]

The new IO system has been integrated into Ikarus, replacing the old system. The new system should provide better support for unicode and almost supports all the features required by the R6RS. There might be some corner cases that I've missed, and some procedures may have been lost in translation. Please do use the new system and report any problems you may encounter.

The major difference between the new and old system is that binary ports are now distinguished from textual ports. Therefore, get-char/put-char are only valid on textual ports while get-u8/put-u8 are only valid on binary ports.

Thanks.

It seems you are trying to use stat() options with open(), which is really not supported on Linux.

[Michael D. Adams (mdmkolbe)]

Sorry, I took another look at it and those options *are* supported (I read it wrong before), you just need to #include <sys/stat.h>.
