I added benchmarks to measure how fast the parallel remove_all code was
-- it turns out, about 3x slower than stdfs::remove_all. Since this was
the case, I removed all of the parallelism and rewrote it serially, and
ended up about 30% faster than stdfs::remove_all (in addition to
supporting symlinks).
In addition, I did the following three orthogonal changes:
- simplified the work queue, basing it on Billy O'Neal's idea
- Fix warnings on older versions of compilers in tests, by splitting
the pragmas out of pch.h.
- Ran clang-format on some files
In fixing up remove_all, the following changes were made:
- On Windows, regular symlinks and directory symlinks are distinct;
as an example, to remove directory symlinks (and junctions, for that
matter), one must use RemoveDirectory. Only on Windows, I added new
`file_type` and `file_status` types, with `file_type` including a new
`directory_symlink` enumerator, and `file_status` being exactly the
same as the old one except using the new `file_type`. On Unix, I
didn't make that change since they don't make a distinction.
- I added new `symlink_status` and `status` functions which use the
new `file_status` on Windows.
- I made `Filesystem::exists` call `fs::exists(status(p))`, as opposed
to the old version which called `stdfs::exists` directly.
- Added benchmarks to `vcpkg-test/files.cpp`. They test the
performance of `remove_all` on small directories (~20 files), with
symlinks and without, and on large directories (~2000 files), with
symlinks and without.
Vcpkg
Overview
Vcpkg helps you manage C and C++ libraries on Windows, Linux and MacOS. This tool and ecosystem are constantly evolving; your involvement is vital to its success!
For short description of available commands, run vcpkg help.
Quick Start
Prerequisites:
- Windows 10, 8.1, 7, Linux, or MacOS
- Visual Studio 2015 Update 3 or newer (on Windows)
- Git
- Optional: CMake 3.12.4
To get started:
> git clone https://github.com/Microsoft/vcpkg.git
> cd vcpkg
PS> .\bootstrap-vcpkg.bat
Linux:~/$ ./bootstrap-vcpkg.sh
Then, to hook up user-wide integration, run (note: requires admin on first use)
PS> .\vcpkg integrate install
Linux:~/$ ./vcpkg integrate install
Install any packages with
PS> .\vcpkg install sdl2 curl
Linux:~/$ ./vcpkg install sdl2 curl
The best way to use installed libraries with CMake is via the toolchain file scripts\buildsystems\vcpkg.cmake. To use this file, you simply need to add it onto your CMake command line as -DCMAKE_TOOLCHAIN_FILE=[vcpkg root]\scripts\buildsystems\vcpkg.cmake.
In Visual Studio, you can create a New Project (or open an existing one). All installed libraries are immediately ready to be #include'd and used in your project without additional configuration.
For more information, see our using a package example for the specifics. If your library is not present in vcpkg catalog, you can open an issue on the GitHub repo where the dev team and the community can see it and potentially create the port file for this library.
Additional notes on macOS and Linux support can be found in the official announcement.
Tab-Completion / Auto-Completion
vcpkg supports auto-completion of commands, package names, options etc in Powershell and bash. To enable tab-completion, use one of the following:
PS> .\vcpkg integrate powershell
Linux:~/$ ./vcpkg integrate bash
and restart your console.
Examples
See the documentation for specific walkthroughs, including installing and using a package, adding a new package from a zipfile, and adding a new package from a GitHub repo.
Our docs are now also available online at ReadTheDocs: https://vcpkg.readthedocs.io/!
See a 4 minute video demo.
