Last change on this file since 2c8a07c was e1c4636, checked in by Erik Nygren <nygren@mit.edu>, 19 years ago
* Added owl::send_zwrite(command, message) to the perl glue to allow for the direct sending of multi-line messages. For example: owl::send_zwrite("-c foo -i bar", "hello"); * Reverted attempted fix for the pagedown problem which just made things worse. * Changed owl_fmtext_print_plain to return an alloc'd string to avoid buffer overrun risks. * Added owl::ztext_stylestrip("...") function to perlglue which returns the ztext with formatting stripped out. * Added colorztext variable which can be used to disable @color() strings arriving in messages after it is set. (Currently, changing its value won't reformat messages). * Outgoing zephyr logging now obeys the logpath variable. * The '~' character in logpath and classlogpath now gets replaced with the user's home directory.
