Andrew Kelley bf03ae7acc std.fs.path.dirname: return null when input path is root
This intentionally diverges from the unix dirname command, as well as
Python and Node.js standard libraries, which all have this edge case
return the input path, unmodified. This is a footgun, and nobody should
have ever done it this way.

Even the man page contradicts the behavior. It says:
"strip last component from file name". Now consider, if you
remove the last item from an array of length 1, then you
have now an array of length 0. After you strip the last component, there
should be no components remaining. Clearly, returning the input parameter
unmodified in this case does not match the documented behavior. This is
my justification for taking a stand on this API design.

ZIG

A general-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.

Resources

Building from Source

Build Status

Note that you can download a binary of the master branch or install Zig from a package manager.

Stage 1: Build Zig from C++ Source Code

This step must be repeated when you make changes to any of the C++ source code.

Dependencies

POSIX
  • cmake >= 2.8.5
  • gcc >= 5.0.0 or clang >= 3.6.0
  • LLVM, Clang, LLD development libraries == 11.x, compiled with the same gcc or clang version above
Windows
  • cmake >= 3.15.3
  • Microsoft Visual Studio. Supported versions:
    • 2017 (version 15.8)
    • 2019 (version 16)
  • LLVM, Clang, LLD development libraries == 11.x

Instructions

POSIX
mkdir build
cd build
cmake ..
make install

MacOS

cd build
cmake .. -DCMAKE_PREFIX_PATH=$(brew --prefix llvm)
make install
Windows

Stage 2: Build Self-Hosted Zig from Zig Source Code

Now we use the stage1 binary:

zig build --prefix $(pwd)/stage2 -Denable-llvm

This produces stage2/bin/zig which can be used for testing and development. Once it is feature complete, it will be used to build stage 3 - the final compiler binary.

Stage 3: Rebuild Self-Hosted Zig Using the Self-Hosted Compiler

Note: Stage 2 compiler is not yet able to build Stage 3. Building Stage 3 is not yet supported.

Once the self-hosted compiler can build itself, this will be the actual compiler binary that we will install to the system. Until then, users should use stage 1.

Debug / Development Build

stage2/bin/zig build

This produces zig-cache/bin/zig.

Release / Install Build

stage2/bin/zig build install -Drelease

License

The ultimate goal of the Zig project is to serve users. As a first-order effect, this means users of the compiler, helping programmers to write better software. Even more important, however, are the end-users.

Zig is intended to be used to help end-users accomplish their goals. Zig should be used to empower end-users, never to exploit them financially, or to limit their freedom to interact with hardware or software in any way.

However, such problems are best solved with social norms, not with software licenses. Any attempt to complicate the software license of Zig would risk compromising the value Zig provides.

Therefore, Zig is available under the MIT (Expat) License, and comes with a humble request: use it to make software better serve the needs of end-users.

This project redistributes code from other projects, some of which have other licenses besides MIT. Such licenses are generally similar to the MIT license for practical purposes. See the subdirectories and files inside lib/ for more details.
