I was using std.regex yesterday, matching a regular expression against
a string with the "g" flag to find multiple matches. As the example
from the docs shows (BTW I think the example may be wrong; I think it
needs the "g" flag added to the regex call), you can do a foreach loop
on the matches like:
foreach(m; match("abcabcabab", regex("ab")))
{
writefln("%s[%s]%s", m.pre, m.hit, m.post);
}
Each match "m" is a RegexMatch, which includes .pre, .hit, and .post
properties to return ranges of everything before, inside, and after
the match.
However what I really wanted was a way to get the range between
matches, i.e. since I had multiple matches I wanted something like
m.upToNextMatch.
I might be wrong but I think that you are looking for std.regex.splitter:
auto s1 =", abc, de, fg, hi,";
assert(equal(splitter(s1, regex(", *")),
["","abc","de","fg","hi",""][]))
Simply put it gets you range of slices of input separated by regex matches.
Since I'm not very familiar with ranges, am I missing some obvious way
of doing this with the existing .pre, .hit and .post properties?
