Is there a way to use the regex library to put matches of

use them to
match a string at the same time and stop if the first one is
found and
keep their results separate (as if the regex was
"(?<=#)\w+\b|(?<=%)\w+\b)" and gave a slice for "(?<=#)\w+\b"
and a
different one for "(?<=%)\w+\b" ). I'm a little new to regexs
for the
record.
For that particular case you can as well use this pattern:
"(?<=#|%)\w+\b"
and then check what character is the last one before your match
by hand:
foreach(m; match(<your string>, "(?<=#|%)\w+\b")){
if(m.pre.back == '#')
//put in one place
else if(m.pre.back == '%')
// put somewhere else
}
More general interface to do it is being discussed recently, in
essence it gives you ability to switch over a bunch of regular
expressions.
See:
https://github.com/D-Programming-Language/phobos/pull/1241
The machinery to efficiently combine regular expressions like
that will come sometime later but the interface should stay the
same.
Nice, that work well for what I'm trying to do when it gets
added. Thanks
