scratchpad text

scratchpad text

[Eric Smith]

I want to on the commandline write some text to guide a task. Then I 
can go like pushline with <esc>-q to move it away and work on my task. 
Then to bring back the "scratchpad" for reading or editing, I go 
<cntrl>-C.

But I could forget to pushline the scratchpad text again and 
just <cntrl>-c it away.

Is there a way to make this "scratchpad"  unlosable, like possibly 
writing it to the history or something even more weird and useful?

Like Functions/Misc/sticky-note, maybe?

Thanks Bart.

I guess I am dreaming a bit, looking for something lighter and 
even simpler.

Looking for just some light RAM space to supplement my own consciousness.
Ideally would like to write to some buffer space in physical top 
corner of screen. Even if editing is not possible. These points
would just supplement my current task or daily todo stuff or whatever.

Possible something like this could be implemented with virtual 
terminals like screen or tmux.

What about putting it in your RPS1 or something?

Cool idea, nicer if I could have  aright justify, trid using ^M for a 
newline and it puts the newline on the left.

How about:

    zle-line-init() {
      print -nR $terminfo[sc]$terminfo[home]"$REMINDER"$terminfo[rc]
    }
    zle -N zle-line-init

Then anything stored in the shell parameter REMINDER will be shown at
the top left of the screen.  Of course it'll begin to scroll off if you
have a multi-line command.

Replace sc/rc with tsl/fsl to use the status line if your terminal has
one (which you can test for by examining $terminfo[hs]).

Nice, I like.
I tried to have a multi-line display (as you pre-empted).
And using ^M as the newline car.
But the second line actually overprints the first line.

This would be a nice to ahve, but the idea is great I will use - it 
thanks.

[eric@pepper ~] $ echo $terminfo[hs]
no

How would I change this?

Kill this question, it works great wrapping to more lines if you just
build a long string and use no newline chars.
I find the scratchpad stand out and more readable when I pad the 
string thus:
print -nR $terminfo[sc]$terminfo[home]"| $REMINDER                         |"$terminfo[rc]

Getting greedy now:
May we have colours?

And a nice easy way to recall the scratchpad text to edit at will.

Thanks for this Bart, its great!

^M is carriage return, ie go to beginning of line. Try echo hello^V^My
for example. If you want to enter literal newlines somewhere, try
^V^J.

Use a different terminal emulator ...

Well ... combining this with my previous suggestion ...

    autoload -Uz sticky-note
    zle -N sticky-note
    sticky-note -b

    zle-line-init() {
      local STICKYFILE=${STICKYFILE:-$HOME/.zsticky}
      local STICKYSIZE=${STICKYSIZE:-1000}

      if [[ -n "$STICKYFILE" && -s "$STICKYFILE" ]]
      then
	fc -ap $STICKYFILE $STICKYSIZE $STICKYSIZE
	print -nr "$terminfo[sc]$terminfo[home]"
	print -nr "$bg[yellow]$fg[black]"
	print -n -- "$(fc -n -l -1)"
	print -nr "$reset_color$terminfo[rc]"
      fi
    }
    zle -N zle-line-init

The print -n -- "$(fc ...)" is there to convert e.g. "\n" in the stored
history into a real newline in the display.  I may need to fix that in
sticky-note itself.

You can pick your own keybinding to invoke sticky-note as a widget,
e.g.

    bindkey ^X^Y sticky-note

You can then move up and down through previous notes to edit.
