Hello,
I want to read a file line by line and store each line in a
string. I found this example with byLine and ranges. First of
all, do I need the range lib at all to do this and if so what
is the range of the end of the file?
You don't need the range lib at all, std.range provides
advanced functions to work with ranges but ranges are a general
concept. You need std.stdio though as this is doing file
operations.
A way to do it is:
void main() {
auto f = File("myfile");
string buffer;
foreach (line ; f.byLine) {
buffer ~= line;
}
f.close();
writeln(buffer);
}
Note that by default byLine doesn't keep the line terminator.
See http://dlang.org/phobos/std_stdio.html#.File.byLine for
more informations.
Thx, cym. I have a question about a D strings though. In c++ I
would just reuse the string buffer with the "=" how can I clear
the string after i store a line in the buffer and do something
with it. I also tried to append a line to an array of strings but
it failed because the line is a char?
