libostd

Work in progress, not ready for production use.

Libostd is an extension of the C++17 standard library which mainly provides ranges (to replace iterators) but also various other utilities like proper streams, string formatting, coroutines, concurrency utilities and others. It's meant to replace the more poorly designed parts of the C++ standard library to make the language easier and more convenient to use.

It is not feature complete right now, as most things are still being worked on.

Documentation for libostd can be found at https://docs.octaforge.org/libostd. Please refer to it for further information (the main page should be answer some more of your questions). You can also read doc/main_page.md and other files in there directly if you don't need the API documentation.

Building

Libostd is built using the supplied C++ build tool. You need to compile the build tool first using the compiler you will use to build the library itself.

On a typical setup, this will involve:

c++ build.cc -o build -std=c++1z -I. -pthread
./build --help

This will typically build using either GCC or Clang with typically libstdc++ as a standard library implementation. Keep in mind that it is you need at least Clang 4.0 or GCC 7.1 to build. To switch to libc++:

c++ build.cc -o build -std=c++1z -I. -pthread -stdlib=libc++
CXXFLAGS="-stdlib=libc++" ./build

If you get undefined references about filesystem, you will need to add extra linkage.

For libstdc++:

c++ build.cc -o build -std=c++1z -I. -pthread -lstdc++fs
LDFLAGS="-lstdc++fs" ./build

For libc++:

c++ build.cc -o build -std=c++1z -I. -pthread -stdlib=libc++ -lc++experimental
CXXFLAGS="-stdlib=libc++" LDFLAGS="-lc++experimental" ./build

You can skip -pthread on Windows.

Using the tool should be straightforward. The ./build --help command lists the available options.

It also recognizes the environment variables CXX (the C++ compiler used to build, defaults to c++), AS (the assembler used to build, defaults to c++ as well, as Clang and GCC can compile assembly files), AR (the tool to create static lib archives, ar by default) and STRIP (the tool used to strip the library in release mode, strip by default).

Additionally, the CXXFLAGS, LDFLAGS and ASFLAGS environment variables are also used. The CXXFLAGS are passed when compiling C++ source files as well as when linking (the compiler is used to link). The LDFLAGS are passed additionally to CXXFLAGS only when linking. The ASFLAGS are passed to the assembler (CXXFLAGS are not, even when Clang/GCC is used).
