* fix crash when window is resized smallerHEADmasterBobby Bingham2015-08-291-3/+6
| | | | | If the cursor was being displayed and its previous position is now outside the resized window, we could crash when trying to erase the old cursor.
* use xor instead of incrementing blinkBobby Bingham2015-08-291-1/+1
| | | | | Because blink is a signed integer, an eventual overflow would result in undefined behavior.
* 1000l: key table was global var rather than static constRich Felker2007-10-031-1/+1

* lame partial support for input methods that give long input stringsRich Felker2007-09-011-1/+3

* minimally working input method support!Rich Felker2007-08-231-1/+5
|
* major internal changes in representation of character cells.Rich Felker2006-10-291-2/+2
| | | | | | | | | | | | | we now use 12 bytes per cell instead of 10. however, this allows us to support 256-color mode (not yet implemented but the framework is in place) and to mix scripts when using combining characters. while the latter sounds ridiculous at first, being able to visibly see a combining letter attached to a [, ", or ' is extremely useful in scripting and regular expressions with some languages. some code is left slightly messy, but overall it's much cleaner now since struct uucell is now properly encapsulated.
* no need to check thisRich Felker2006-10-261-2/+0

* basic, primitive paste support. it is blatently incorrect for non-utf8Rich Felker2006-10-261-5/+39
| | | | | | | locales, and will also fail when the selection owner cannot provide utf-8 encoded text. much more support code is needed, but at least this is a start.
* stupid omission; still a glitch though..?Rich Felker2006-10-251-0/+1

* major changes to input handling in preparation for pasting, which willRich Felker2006-10-251-26/+22
| | | | | | | | | | | | | | | | | | | | require support for large blocks of input: output which cannot be written to the tty (pty) is no longer discarded. instead, the display module is responsible for keeping the buffer alive until it has been entirely consumed. one simple (and smart) way to ensure this is to refuse to process events that could generate new input text as long as there is unwritten data. this works as long as there is an earlier layer of buffering (for fbcon, kernel; for x11, xlib). a direct-on-x-protocol display implementation will have to do its own buffer management. this architecture allows pasting to be performed direct from a buffer owned by the display module, which could reside in static or shared memory, or even as a memory-mapped file. it also facilitates reuse of the code in non-tty-connected settings.
* mistaken line left over from old codeRich Felker2006-10-161-1/+0

* don't know if this is a bug somewhere else, but for whatever reason iRich Felker2006-10-161-0/+1
| | | | | was getting non-null-terminated strings sometime?!
* remove server-side glyph rendering/cache entirely. client side is justRich Felker2006-10-151-66/+55
| | | | | | as fast or faster even with remote displays due to horribly inefficient X protocol...
* revert "performance increase" that actually hurt performance on betterRich Felker2006-10-151-30/+19
| | | | | | | X servers.. :( some better approach is really needed; at this rate, even client side images would be faster...
* large performance increaseRich Felker2006-10-151-19/+30

* remove the horribly incorrect XImage handling and replace it withRich Felker2006-10-131-21/+16
