something like
assert (f("abc\ndef") == "\"abc\\ndef\"");
It's a bit hackish, but it avoids deploying code and reinventing
anything. You can use format "string-range" formating to print
the string escaped. Catch that, and then do it again:
string s = "abc\ndef";
writefln("[%s]\n", s); //raw
s = format("%(%s%)", [s]);
writefln("[%s]\n", s); //escaped
s = format("%(%s%)", [s]);
writefln("[%s]\n", s); //escapes are escaped
As you can see from the output, after two iterations:
[abc
def]
["abc\ndef"]
["\"abc\\ndef\""]
I seem to recall that printing strings "escaped" has been
requested before, but, AFAIK, this is the best we are currently
providing.
Unless you call std.format's "formatElement" directly. However,
this is an internal and undocumented function, and the fact it
isn't private is probably an oversight.
