Settling down to write my first app but have come to a grinding halt. This is my first system-level language so I'm afraid I'll be asking some naïve questions.
All I'm trying to do is read a text file with Windows line endings into an array for line-by-line processing.
The relevant function appears to be std.stdio.File.byLine.
The default isn't breaking the lines properly, so I have to pass in the line ending. But the signature has me baffled:
auto byLine(Terminator, Char) ( KeepTerminator keepTerminator = No.keepTerminator, Terminator terminator = '\x0a' ) if (isScalarType!Terminator); auto byLine(Terminator, Char) ( KeepTerminator keepTerminator, Terminator terminator ) if (is(immutable(ElementEncodingType!Terminator) == immutable(Char)));
To specify the line ending, it appears to be asking for a type "Terminator" which I can't find in the library. Doing the obvious doesn't work:
// Err: cannot deduce function from argument types myFile.byLine(`\r\n`);
Also, how would you specify the Char type as a parameter?
The examples are unenlightening as they only show the default case, so any help would be much appreciated. Any wider tips on how to read these cryptic signatures would be a bonus!
