Ask HN: Why on God's beautiful Earth does std::string not have a trim()?

• coreyp_1 11y ago
  Now, now... we don't want it to look too much like those silly scripting languages, do we? (Serious answer: I have no idea, and despite having written a lot of C++ over the years, I've actually never needed to use a trim(), so I never noticed that it was missing! I learned something new in the middle of my insomnia!)

    I use it all the time in other languages like Clojure, and now needing to use it in C++ I am finding that lots of people have their own implementations for it laying around. Just look at all the ad-hoc trim()s on stackoverflow. Ridiculous. Such a basic string feature, yet std can't provide it for reasons unknown.

      http://www.cplusplus.com/forum/general/115700/ http://www.cplusplus.com/forum/general/115700/ Here is a good "explanation" as to why, and I suppose it's as good as any other. The forum post does recommend using boost, though, which is a common c++ staple.
