Virgil Dupras 838c88459b Make BLK@ FLUSH only if loading a different block
Otherwise, when editing a file with VE, we would constantly write
to disk, which is a bit inefficient.

Virgil Dupras e317e9cc78 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.

Virgil Dupras 4146110e0d Move EMPTY to core words
It's a quite useful word and it doesn't make sense to reload it from
disk after each usage.

Virgil Dupras f6ded7712e VE: add 't'
This is the first commit I do entirely in VE. It's a habit I'm planning
on taking as it helps a lot to find usability issues.

Virgil Dupras e83d5073ba VE: disallow buffer overflow during typing
When reaching the end of the buffer when typing in IBUF or FBUF, stop
typing instead of overflowing.

Virgil Dupras a405f77185 ed: don't crash when inserting in 64th char of the line 2020-06-10 20:56:19 -04:00
Virgil Dupras 7cad9ffe40 LIST: simplify logic
There wasn't much of a reason to leave a loop early on 0x0d or null.
The idea was that once you have a CR or null, the rest is garbage
and you shouldn't see it.

However, it brought a problem: In VE, you couldn't insert characters
past that limit. It would be written, but never displayed. So let's
get rid of this logic and simply always display a 64x16 grid.

Virgil Dupras 6a6c59300e VE: make ACC reset after each non-digit keystrokes
It simplifies things. Also, removed ';' which became useless.

Virgil Dupras 64ce8ab3e9 ed: Improve F with repeated searches
Make F search from curpos+1 so that it's possible to search the
same word we've just found a second time. Previously, it would find
the word under the cursor.

Also, improve docs a bit.

Virgil Dupras b2a07ca68d Remove mailing list link from README
I think we can say it didn't take off.

Virgil Dupras 4d893d90fc 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).

Make blkpack close files when it's done reading them (#108)

Virgil Dupras bcddfd461d blkpack: Remove usage of nonstandard d_type
The man page says it's not always available and it caused problems
under some FSes. The condition is not needed in the context of
blk/, let's scrap it.

Virgil Dupras a36db99651 VE: properly initialize variables
This fixes weird glitches I had on trs80. It's *always* a matter of
RAM initialization. By now, I should know...

Virgil Dupras b2b556911f trs80: implement AT-XY
Also, I've run VE on the TRS-80 for the first time! It doesn't work
well though. Screen is mostly blank all the time.

I removed instructions from the recipe which became obsolete when
Collapse OS became 100% bootstrapped. Also, I've updated instructions
to change the NL override which is necessary for blkup to work.

Virgil Dupras b22ab8437b 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.

Virgil Dupras e7a6c777c7 VE: refactor mode indicators
The indicator is going to be empty most of the time and will be
emitted by the mode changer directly. That's going to the upper-right
corner and the status bar avoids emitting in that area.

Virgil Dupras 4af93d53e3 VE: add I command
Also, add insert and find buffers to the header, making it 3 lines
high.

Also, fix the "I" overshadowing word which wasn't operating on the
proper RSP level.

Also, fix I which didn't mark the block as dirty.
