} The ones that are substituted, i.e. if #m knows that it will replace
} "vim", it should give indexes for that substring, and if it knows it
} will replace "s", then should give indexes for it, etc.
On closer inspection, your problem isn't what I thought it was. Note
this bit of the doc:
m
Set references to the match data for the entire string matched;
this is similar to backreferencing and does not work in filename
generation. The flag must be in effect at the end of the pattern,
i.e. not local to a group.
When you do
(#mi)this|that
The #m ends at the "|", and so is not "in effect at the end of the
pattern" which is after "that". So if you change your expression to be
one of
harray=( "${(f)${text//(#mi)(${~colsearch_pattern})/|$(( MBEGIN - 1 )) $((
MEND )) fg=red,bold|$nl}%$nl*}" )
[added parens around the alternates] or
harray=( "${(f)${text//(#i)${~colsearch_pattern}(#m)/|$(( MBEGIN - 1 )) $((
MEND )) fg=red,bold|$nl}%$nl*}" )
[moved (#m) to the end] then $MBEGIN et al. work as you desire. I suspect
you actually want the first with the parens because otherwise the (#i) also
ends at the "|".
