Just

to write out the whole hit instead of the collection of
references.
What can be wrong with this regexp?
https://regex101.com/r/8e7nPL/3
it's crush D compiler, and I can't find out why
I need simply select parts from one first-level # to another.
like:
#header
some text
and some code
^ first matching
#header2
some text2
and some code2
^ second matching

That's just the writeln array formatter. The matchFirst
function returns an array of hits (that allows captures, btw
you might need to use \( instead of ( to get the capture, god i
hate regex) so writeln tries to print the whole array and
that's how it does embedded newlines.
So you have the correct result, just written strangely.
How should I write to file result without \r\n\ symbols?
auto x = content.matchFirst(bigCodeBlock);
File f = File("foo.txt", "w");
f.write(x);
foo.txt:
["```\r\nvoid foo()\r\n{\r\n\twriteln(\"ppp\");\r\n}\r\n```"]

\r\n is Windows new line characters.

Sorry, but what regexp are you talking? There is nothing like:
`regex("/.*/g")` in my code...
Yes there was:
auto bigCodeBlock = regex("/`{3}[\\s\\S]*?`{3}/g");
I still can't get it work in real code :(

But after compilation of code:
auto x = content.matchFirst(bigCodeBlock);
writeln(x);
print:

It's seems that D regexp work in another way. How can I test them?
