VE: allow usage on screens narrower than 67 columns Previously, display would be completely broken. We have yet to add a way to display the "right" part of a buffer on such smaller displays. 2020-11-13 15:52:12 -05:00			`: contents 16 0 DO large? IF 3 ELSE 0 THEN I 3 + AT-XY`

VE: decouple from core's LIST I'm planning on de-hardcoding columns in VE a bit to add support for screens narrower than 67 columns. There's a lot of hardcoding. Let's begin with not using core's LIST anymore. This allows us to spit 1-16 numbers only at startup. 2020-11-13 15:19:00 -05:00			`I C@ 0x20 MAX EMIT LOOP LOOP`

VE: add command 'f' Kinda proud of this one. Efficiently piggy-backing on the Block Editor, keeping things simple, and yet, building power into the editor. 2020-06-06 21:46:46 -04:00			`: cmv ( n -- , char movement ) acc@ * EDPOS @ + pos! ;`
VE: Improve I and F buffer typing Previously, it would keep the old buffer displayed why typing over it. I had kept it thus because I didn't want to erase the buffer right away because the behavior is that when we type nothing, we keep the buffer as-is and repeat the action. Now, the behavior of I and F is much better. It keeps the buffer displayed until the first non-return keystroke and then erases it. Also, fixed PSP leak in _type and fixed PSP overuse in successful _F (they balanced out). 2020-06-08 21:23:23 -04:00			`: buftype ( buf ln -- )`
VE: use system input buffer for IBUF and FBUF typing This gives us backspace handling. Also, remove all usages of C< which allows us to remove the C<* override. 2020-06-11 20:31:18 -04:00			`3 OVER AT-XY KEY DUP EMIT`
