Subject: Re: Match to the end of string when using (S) flag
Date: Tue, 01 Nov 2016 09:27:53 -0700	[thread overview]
Message-ID: <1478017673.3085741.773974873.7C58DD0B@webmail.messagingengine.com> (raw)
In-Reply-To: <1478010333.3056500.773811025.1AAA4FEC@webmail.messagingengine.com>

One solution can be:

local nul=$'\0'
region_highlight+=( "${(0)${(S)text//*(#bi)(${~colsearch_pattern})/$((
offset + mbegin[1] - 1 )) $(( offset + mend[1] ))
${__hsmw_hl_color}${nul}}%$nul*}" )

however user probably can enter or somehow have in history a null byte?
That said, the solution is rather acceptable. Generates clean
region_highlight entries and in emergency case of a null byte in $text
after last match – relies on Zshell's robust region_highlight
implementation converting improper entries to "-1 -1 none". Provided
there is no other way, this is fine. But maybe there is other way?
