C++Now 2015

C++ Now 2015. Today is the official release of Spirit X3, aka Spirit 3.0.0. X3 will be in beta, coexisting side by side with Qi, Karma, Lex and Classic.

If you are a Qi user, the best place to start are the examples, especially rexpr and x3 fun.

Remember to use a compiler with c++14 capabilities:

  • clang 3.4 or greater
  • gcc 4.9 or greater


Docs: X3 Documentation

Slides: Using X3 Slides

Spirit X3 Source


Use the develop branch.

Zip of develop:

You will find boilerplate (getting started) projects in: example/x3/rexpr
There are two directories.

  • rexpr_min – contains a single file to start things off.
  • rexpr_full – contains a structure similar to the one in the presentation complete with tests.

X3 Fun

    Fantastic! Looking forward to a cleaner api with faster compile times 🙂

    Do you expect support for Visual Studio 2015/msvc 13 to be forthcoming?

    Great work. I like the new interface much better than the old one…

    PS: You should consider putting a note with a link to this page into the official boost documentation, so that the newcomers (like me :)) don’t waste time learning about the old version.

  3. Jeff says:

    will Spirit V3 be part of boost 1.60 or maybe 1.61?

    Also, should I build spirit V3 within/alongside the other boost libraries, at the same time?

    How do I use bjam to build after alreadybuilding the rest of boost? I.e., how to tell it where to find my boost install?

    I just wanted to notify you that the links to the docs and slides are broken.
    It would be of tremendous help if you could actualize the link to the documentation.
