Oh, well that's a relief. I haven't been missing anything, then! H-)
But speaking of linewrap...
I've been realizing that with most of the world is reading email on
their phones these days, I should have a way of composing email that's
one paragraph to a line, so that the text wrapping on a narrow screen
gets a fighting chance. I'm sure that if you read this message on a
phone it will look terrible.
vile's linewrap does the right thing with long lines, but there's no
easy way to move up and down vertically within a long wrapped line
that spans multiple screen lines.
Has anyone ever written a key binding that will go up and down by
screen lines (as opposed to real lines) when in linewrap mode? (Or,
have I been oblivious, and is there already a way to do this?)
I.e., I want bindings that will move the cursor up and down throught
the same column in every line of the screen, whether part of a wrapped
line, or not. Extra points for maintaining a "desired goal" column
when passing through a screen line that's too short.
I started trying to write stored procedures to do this, and have actually
gotten it to work in the forward/down direction, but going the other
way is kicking my butt.
Here's what I've got, going forward, if anyone's interested.
store-procedure forw-in-lw-line
~if > $lcols $curcol
; unless we're at a line that's shorter than where we
; started, add another page width to our current column
set-variable %nextcol &add $curcol $pagewid
~endif
~if &leq %nextcol $lcols
; our "next" column is still on the line, so go there
~force %nextcol goto-column
~else
; if we're trying to go past the end of the line, go to
; the next line, instead.
~force down-line-at-bol
~force &modulo %nextcol $pagewid goto-column
~endif
~endm
bind-key forw-in-lw-line +
bind-key forw-in-lw-line =
You'd think going backward would be a simple inversion of the code,
it's harder than that. For me, anyway!
