Virgil Dupras 3f38c025e7 VE: add support for tight screens 2020-11-13 20:44:39 -05:00
Virgil Dupras 74e211eeda Fix bugs in ed's U and VE's O/o 
U didn't properly handle inserting on the last line and O's bounds
checks didn't make sense.

Virgil Dupras 9ab5cda397 ed: rename I to i 
Shadowing core "I" is too messy. As soon as ed is loaded in memory,
nothing else that isn't "i-aware" can be loaded anymore.

I guess that's why "contexts" exist in Starting Forth, but adding
this concept just for allowing the shadowing of core words seems
overkill to me. Renaming I to i in ed seems better.

Virgil Dupras 1871c46614 VE: add backspace support in replace mode 2020-06-11 22:29:05 -04:00
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 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 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 204a66277e VE: replace 'W' with 'b' and implement 'W' and 'B' 
Which are end-of-word movements.

Virgil Dupras 4c1cacd8d0 Remove Linker 
Now that the boot binary is fully cross-compiled, there's no use for
the linker anymore. Theoretically, it could still be useful, but I
can't think of a real use case.

Let's take it out of the picture. If it's ever needed again, I'll
know where to find it.

There was a weird empty block in the middle of the program.
