Hi, I'm currently working on reading and parsing large ASCII based text files and I am wondering what is the current best practice. There are so many classes and macros available, so it can be a bit confusing to know what to use when.
QString, QLatin1String, QByteArray, QStringLiteral, QLatin1Literal, QByteArrayLiteral, plain C++ string literal, QStringRef, QStringBuilder and so on. And then std::string and raw const char* strings. In my case I want to read a large ASCII file line by line, so I don't need unicode. I need to compare a string with a literal, extract substrings and convert some strings to numbers. Should I just use QString all the way, or is it faster to use some other classes when you know you don't need unicode? Any hints on fast file parsing code in Qt itself that I could use as a guildeline? Thanks, Harald
