A modern C++ library by Kevin Wichmann (TyRoXx). It contains generic components he needs in other personal projects and experiments that will be moved to their own libraries or removed eventually.

Nothing in here is well tested or ready for production yet. Any API can change at any time before version 1.0 (see <silicium/version.hpp> for the current version).

• the library is continuously tested with several versions of GCC on Ubuntu 12.04 (Boost 1.54 and 1.55)
  • tested GCC versions: 4.9
  • only works with at least C++11 enabled (-std=c++0x, -std=c++11, -std=cpp1y etc)
• 
  • Visual Studio 2015 is tested with Boost 1.56
  • Visual Studio 2013 worked at one point, but is no longer tested regularly
• Clang is not being tested regularly yet
• OSX, BSDs and architectures other than x86 or AMD64 have not been tried yet

There will be documentation when the APIs have stabilized to some extent.

very work-in-progress, incomplete and usually outdated Doxygen

Occasionally the library is pushed to https://conan.io, the central registry of the C++ package manager. The official packages by the author of silicium will look similar this: silicium/*.*@TyRoXx/master

You can find the latest version by searching on the web site ( https://www.conan.io/search?q=silicium) or by using the command line:

conan search -r conan.io silicium

There are no binary packages, but you can require silicium anyway because it is headers-only.

This installs the dependencies on Ubuntu 14.04:

sudo apt-get install libboost-all-dev liburiparser-dev zlib1g-dev

On ancient operating systems, you may have to install some of the libraries from a recent source release.

Many components of the library are only available with more recent versions of Boost though.

http://www.boost.org/users/download/

sudo apt-get install libboost-all-dev

http://uriparser.sourceforge.net/#download

sudo apt-get install liburiparser-dev

http://zlib.net/

sudo apt-get install zlib1g-dev

• continuous integration
  • use travis for OSX
  • appveyor improvements
    • multiple Boost verions
    • use conan.io
  • get valgrind to work without false positives
  • measure test coverage
• check whether variant<T &> makes sense
• Asio-style async_wait for the end of a child process
• async read and write for anonymous pipes on Win32
• clean up noexcept annotations
• prevent all integer overflows in the library
• noexcept function to load a dynamic library
• replace the "trait" concept with the new "delegator"
• try precompiled headers
• rename error_or<T, boost::system::error_code> to system_result<T>?
• move everything HTTP into a separate library
• move the web server stuff to a separate library (including the uriparser dependency)
• clean up and clarify the build instructions
• document the unit tests
• document the #include tests
• remove obsolete examples
• consider replacing Si::variant with eggs::variant

• static analysis
• move the zlib wrapper to a separate library
• define operator<< for basic_ostream, not ostream
• optimize safe integer arithmetic
  • GCC/Clang intrinsics?
  • avoid the div in operator*
• emulate variadic templates so that variant works on old compilers for a limited number of arguments
• drop-in replacement for boost::asio::spawn that works properly with old Boost versions
  • spawn does not support immediate completion prior to Boost 1.58
• a generic, ASIO-style "AsyncSource" concept which replaces Observable

• ASIO-style websockets
• investigate async read and write for files
• further investigation of container wrappers like Si::vector
• play with Visual C++ 2015 await: http://blogs.msdn.com/b/vcblog/archive/2014/11/12/resumable-functions-in-c.aspx
