* Remove some case statements which have been compiled out since 2000.fcambus2017-08-101-20/+1
| | | | OK mpi@
* Partially revert previous mallocarray conversions that containdhill2017-04-111-5/+5

* UTF-8 support for wsdisplay emulation modes. Both vt100 and sun emulationmiod2013-10-181-85/+204
| | | | | | | | | | | | | will now recognize xterm-compatible escape sequences ESC % G and ESC % @ to enter and leave UTF-8 mode, respectively. Not enabled on SMALL_KERNEL. Most of this written during c2k7, completed during b2k13. Note that the value of several international keysyms change, to switch from ISO Latin-[257] values to the real Unicode values. Be sure to update your includes and rebuild and install wsconsctl.
* Introduce a dedicated private header file to control the optional featuresmiod2013-10-181-8/+5

| | | | | | | | | | column and and clear VTFL_LASTCHAR if so. This fixes the case where an escape sequence (originally noticed with DECSTBM) moves the cursor and doesn't reset the flag - if it was set, there would be a spurious line feed on the next input. ok miod
* Check the return value of all emulops in the emulation code, and abortmiod2009-09-051-68/+216
| | | | | | | | | | | | tty output as soon as we hit a failure. Since the `output' of a character may cause several emulops to be called (e.g. if it causes scrollup or if this is the end of an escape sequence), all emulation code maintain a so-called `abort state', to be able to properly recover when the character is tentatively output later, and not reissue the emulops which did not fail the first time. With help from mglocker@

* Some dynamically allocated elements are not considered of vital importancemiod2007-01-071-107/+110
| | | | | | | | | | | | for the vt100 emulation to work well enough for most cases (i.e. alternate character set tables, non-default tab settings, etc). However, code did not always check if these elements had been successfully allocated before trying to use them, or worse, would explicitely panic in DIAGNOSTIC kernels. Change this to work in a degraded mode (by ignoring related escape sequences) instead.
* Change allocations to M_NOWAIT in attach methods, and return NULL if they fail.miod2007-01-071-2/+4
