AaronSteen ceb7eb5230 build(windows): restore tee.exe on Windows #36363
Problem:
Neovim no longer ships with a tee binary on Windows, which breaks
functionality for the :grep and :make commands.

    nvim --clean
    :grep foo or :make
    "tee is not recognized as an internal or external command"

Solution:
Include a simple, no-dependency tee.c source file in the src/ directory.
Update CMakeLists.txt to build a tee executable alongside neovim during
the build process, and ensure the tee.exe program appears alongside the
neovim executable in the bin/ directory so that it is accessible for
:grep and :make.

tee.c was obtained from the vim codebase:
https://github.com/vim/vim/blob/master/src/tee/tee.c

And we modified it to fix performance issues.

Testing:

    nvim --clean
    :grep foo or :make, after setting a file to the makeprg option.
    Verify that :grep results and error output from a compiler appear in the message pane.

Other tee options:
- [tee-win32](https://github.com/dEajL3kA/tee-win32): MIT. However,
  I couldn't get it to build on my machine even after updating its
  makefile to call my install of MSVC. It's also super optimized and
  uses some processor intrinsics for multithreading.
- [gnu coreutils tee](https://gnuwin32.sourceforge.net/packages/coreutils.htm):
  (Windows coreutils contains a tee.c. Last updated 2005. Did not build
  immediately on my machine; we'd have to determine which definitions
  from elsewhere in coreutils tee.c needs and incorporate them somehow.
- [WinTee](https://github.com/mpderbec/WinTee): Has no license. Last
  updated 11 years ago. Relies on Visual Studio to build.

Neovim is a project that seeks to aggressively refactor Vim in order to:

See the Introduction wiki page and Roadmap for more information.

Features

See :help nvim-features for the full list, and :help news for noteworthy changes in the latest version!

Install from package

Pre-built packages for Windows, macOS, and Linux are found on the Releases page.

Managed packages are in Homebrew, Debian, Ubuntu, Fedora, Arch Linux, Void Linux, Gentoo, and more!

Install from source

See BUILD.md and supported platforms for details.

The build is CMake-based, but a Makefile is provided as a convenience. After installing the dependencies, run the following command.

make CMAKE_BUILD_TYPE=RelWithDebInfo
sudo make install

To install to a non-default location:

make CMAKE_BUILD_TYPE=RelWithDebInfo CMAKE_INSTALL_PREFIX=/full/path/
make install

CMake hints for inspecting the build:

  • cmake --build build --target help lists all build targets.
  • build/CMakeCache.txt (or cmake -LAH build/) contains the resolved values of all CMake variables.
  • build/compile_commands.json shows the full compiler invocations for each translation unit.

Transitioning from Vim

See :help nvim-from-vim for instructions.
