Today I released v1.5.0 of ghc::filesystem , my implementation of C++17 std::filesystem for C++11, C++14, C++17 and C++20.

This release is the result of a major refactoring: on Windows fs::path now stores the native path-representation with wchar_t as value_type, removing a mutable cache that was inherently not thread-safe and avoiding lots of conversions on calls to the Win-API.

std::filesystem Implementation Corner Cases, part 2

Sat, 08 Feb 2020 23:30:19 +0100

A question on StackOverflow was pointing at another corner case where the current implementations of std::filesystem differ, it is about the handling of a trailing directory seperator when calling std::filesystem::create_directories().

ghc::filesystem Release v1.3.0

Sat, 08 Feb 2020 19:30:35 +0100

Today I released v1.3.0 of ghc::filesystem , my implementation of C++17 std::filesystem for C++11, C++14 and C++17.

The main reasong for this release is the switch from BSD-3-Clause license to the MIT license.

I originally decided on BSD because of the detailed clauses it features, to make things clear, but it was not an easy decision at that time, but I had to pick one.

About a week ago I was asked if it would be possible to use MIT license and at first I was against a change, but I thought about it and decided a even ore liberal license would give more projects the chance to use it, so my only concern left was, if I would be able to reach all contributors and if they would agree to the license change.

I was amazed to see, all anserwed in just a few days and all agreed so they made the decision an easy one for me.

std::filesystem Implementation Corner Cases

Sun, 22 Dec 2019 13:24:31 +0100

On this years Meeting C++ I had the chance to talk with a lot of people and it was very inspirational. With some I talked about ghc::filesystem , my implementation of a C++17 std::filesystem compatible library. Part of this discussions was about some corner cases I found during my tests, and I was trying to remember the details when I was having the chance to talk to @NicoJosuttis . He among others was interested in these issues, as they might be rooted in unclear passages of the standard.

ghc::filesystem Release v1.2.10

Sun, 24 Nov 2019 16:42:51 +0100

Today I released the bugfix release v1.2.10 of ghc::filesystem , my implementation of C++17 std::filesystem for C++11, C++14 and C++17. There were some issues, all on the Windows part, so it was time to fix them with a release.

While at it, I updated the CI configuration files to add newer compilers and the set used for CI and tests is now:

macOS 10.12: Xcode 9.2 (clang-900.0.39.2), GCC 9.2, Clang 9.0, macOS 10.13: Xcode 10.1, macOS 10.14: Xcode 11.2
Windows: Visual Studio 2017, Visual Studio 2015, Visual Studio 2019, MinGW GCC 6.3 (Win32), GCC 7.2 (Win64)
Linux (Ubuntu): GCC (5.5, 6.5, 7.4, 8.3, 9.2), Clang (5.0, 6.0, 7.1, 8.0, 9.0)

ghc::filesystem Release v1.2.8

Fri, 15 Nov 2019 09:10:03 +0200

During these days I’m on the Meeting C++ 2019 and so far it is a great event. This morning before leaving my hotel, I used the inspirational spirit and released v1.2.8 of ghc::filesystem . This is mostly a bugfix release, but there is a new CMake option to select wether or not an install target should be added to the build files.

Additionally, five pull requests found their way into this release, and I want to thank the supporters for their work.

ghc::filesystem Release v1.2.6

Sat, 21 Sep 2019 17:45:08 +0200

Today I released v1.2.6 of ghc::filesystem . The main reason was an issue with fs::path::preferred_seperator. The previous implementation didn’t compile on pre-C++17 compilers when the seperator was accessed. The Bugfix for #27 , was a bit more work than expected, but now it works on all tested compilers.

Additionally, two pull requests found their way into this release, and I want to thank the supporters for their work.

ghc::filesystem Release v1.2.4

Sun, 11 Aug 2019 10:21:07 +0200

Today I released v1.2.4 of ghc::filesystem . It mainly contains a fix for issue #22 , where ghc::filesystem::copy() wouldn’t allways forward given copy_options to a ghc::filesystem::copy_file() call.

ghc::filesystem Release v1.2.2

Sun, 23 Jun 2019 16:50:38 +0200

Today I released a bugfix version of ghc::filesystem . It only contains a fix for issue #21 , where compiling on Alpine Linux with musl instead of glibc chooses the wrong strerror_r signature.

The musl headers sadly don’t conform to the preprocessor expression of the linux man file (_POSIX_C_SOURCE >= 200112L || _XOPEN_SOURCE >= 600) && ! _GNU_SOURCE for strerror_r, so there was no well defined preprocessor way of solving this.

ghc::filesystem Release v1.2.0

Sun, 02 Jun 2019 13:13:26 +0200

Today I released v1.2.0 of ghc::filesystem , my implementation of C++17 std::filesystem for C++11, C++14 and C++17.

This release added MinGW 32/64 and Visual Studio 2015 builds to the CI configuration and brought new optional features, like a standard conforming wchar_t/std::wstring interface on Windows and optional unicode errors, along with a set of bug fixes.
