Boost.Filesystem v4 will contain breaking changes from v3 that are required
for better compatibility with C++17 std::filesystem. It will also remove
the deprecated features of v3.
Updated docs to reflect the differences between v3 and v4. Updated tests
to verify both v3 and v4 where the differences are present.
This is a breaking change.
path::filename accessor now only returns the actual filename or the implied
trailing dot element of the path, if it ends with a separator other than
root directory. This makes boost::filesystem::path behavior closer to that
of std::filesystem::path.
Updated tests and docs accordingly.
Closes https://github.com/boostorg/filesystem/issues/194.
- Unified root name and root directory parsing that was scattered and
duplicated across different algorithms. The new implementation is
consolidated in a single function for parsing root name and root
directory, which is used from various algorithms.
- The new root name parsing now supports Windows local device ("\\.\")
and NT path ("\??\") prefixes. It also adds support for filesystem
("\\?\") prefix to some of the higher level algorithms that were
using custom parsing previously. Tests updated to verify these prefixes.
- Some of the path decomposition methods were unified with presence checking
methods (e.g. root_name with has_root_name). This makes these methods
work consistently and also makes the has_* methods less expensive as
they no longer have to construct a path only to check if it is empty.
- The filename accessor no longer returns root name if the whole path
only consists of a root name. This also affects stem and extension as
those accessors are based on filename. This is a breaking change.
- Cleaned up code:
- Removed redundant checks for std::wstring support.
- Added header/footer headers to globally disable compiler warnings.
- Removed commented out super-deprecated code.
- Added missing includes and removed includes that are not needed.
- Nonessential code formatting.
When using Boost.Filesystem from a project compiled as C++/CX code,
compilation fails with a syntax error, because generic is a keyword.
error C2059: syntax error: 'generic'
