~ Robert is tall
~ Linda is a brunette ~ Dieter who lives in Berlin speaks English fluently
~ Robert is smaller than Linda
~ Dieter said : Speak you Deutsch ?
~ Linda is as blonde as Robert is dark, and, at 5ft 6, much taller than him
etc…
NB : each line is tagged, thanks to a Dictionary (for example : Robert is
tall @RN &Washington), and those tags are highlighted.
In order to verify that there are no errors/contradictions in my text, what
I wish is :
1) to "filter" patterns (e.g. Robert) 2) into a different full-page buffer (not in a window at the bottom of the
screen),
3) where I can suppress the errors/contradictions
4) while keeping the highlightings
The possibilities seem (for a learner) to be :
a) * on the word Robert : satisfies partly 1), 3) and 4) but is not
efficient with a long file
b) :g/Robert/p : satisfies 1) but not 2) (window at the bottom) nor 4) ; as
for 3), I do not know
c) [I : same results as with :g/Robert/p
d) :vimgrep /Robert/ %, then :copen : same results as with :g/Robert/p, with
a new inconvenience : each line is populated with its own path (which is of
course necessary when quickfixing multiple files)

How about:
1. :%y to copy (yank) all text in the buffer
2. :tabnew to open a new, empty "full-page buffer"
3. p to paste (put) the copied text
4. do whatever you do to re-apply highlight
5. :v/Robert/d to remove all lines where "Robert" is not present
I have no idea whether you can "suppress the errors/contradictions" in an
automated fashion. If you can find an algorithm to do that in general, certainly
it can be done in Vimscript (or Perl, python, Lua, etc.), even if it takes some
heavy-duty scripting.
In fact I simply want to suppress errors manually, so, no need for
automation, nor AI.
All I wish is to have the possibility :
- to "filter" the relevant lines into a full-page buffer (and not a window
at the bottom of the screen)
- ... as if all the other lines had disappeared
- where I can see them with their highlighting preserved
- where I can modify them efficiently by concentrating on one pattern at a
time
- and then go back to the file and find the lines as modified by me in the
"filtering buffer".
One question, nevertheless : I have already set my fold method to an
expression found in the Vim documentation :
/This will make a fold out of paragraphs separated by blank lines:
:set foldexpr=getline(v:lnum)=~'^\\s*$'&&getline(v:lnum+1)=~'\\S'?'<1':1/
Is it possible to have 1 fold method (expression) and 2 expressions for 2
different situations, and in that case, a usual expression (folding on
paragraphs) plus an expression specific to a tab split ?

this isn't exactly what you are asking for, but it's close, and I feel
may be of use to some, possibly yourself. I've had fun with a folding
tool:
with these mappings, after any search if I hit <Leader>o I get every
line that doesn't have my search pattern folded away into oblivion and
only lines with my search pattern are visible (and easy to work with).
My mnemonic when working with these mappings is to think "only."

Yes. The 'foldexpr' option is local to the Window. So you can do whatever you want in a split window/tab without affecting the first window/tab. Just be sure to use :setlocal and not :set.

yes, that's it exactly -- it's very useful
when done you can restore normality via <Leader>oo
