Deprecated names and features

As the library evolves over time, names sometimes change or old features are removed to make way for new features. To ease transition, Boost.Filesystem deprecates the old names and features, but by default continues to provide many of them. The deprecated names and other workarounds can be suppressed by defining macro BOOST_FILESYSTEM_NO_DEPRECATED, and this is recommended for all new code.

In the table, ✔ indicates a synonym or other workaround is provided unless BOOST_FILESYSTEM_NO_DEPRECATED is defined.

Component or location

Old name, now deprecated

class path branch_path() parent_path()
class path canonize()   Function removed
class path default_name_check() Function removed
class path default_name_check(name_check) Function removed
class path default_name_check_writable() Function removed
class path directory_string() string
class path external_directory_string() native()
class path external_file_string() native()
class path file_string() string()
class path has_branch_path() has_parent_path()
class path has_leaf() has_filename()
class path is_complere() is_absolute()
class path leaf() filename()
class path native_directory_string() string()
class path native_file_string() string()
class path normalize() Function removed
class path path(const string_type& str, name_check) Function removed. Workaround ignores name_check argument.
class path path(const string_type::value_type* s,  name_check) Function removed. Workaround ignores name_check argument.
class path

remove_leaf()

remove_filename()

path.hpp template<class String, class Traits>
  class basic_path;
  Class template basic_path is replaced by class path. No workaround for an explicitly coded basic_path is provided, but see the next row - path.
path.hpp typedef basic_path<std::string, path_traits> path class path
path.hpp typedef basic_path<std::wstring, wpath_traits> wpath Removed; use class path instead. Workaround provides typedef path wpath
operations.hpp initial_path() Function removed
operations.hpp

template <class Path>
Path complete(const Path& p,
 const Path& base=
   initial_path<Path>())

path absolute(const path& p, const path& base=
  current_path())

operations.hpp is_regular(file_status f)

is_regular_file(file_status f)

operations.hpp symbolic_link_exists(const path& ph)   Function removed
class directory_entry filename() Function removed, use path().filename() instead.
class directory_entry leaf() Function removed, use path().filename() instead.
class directory_entry string() Function removed, use path().string() instead.
Macro definitions BOOST_WINDOW_API   No longer supported; API selection is always automatic.
Macro definitions BOOST_POSIX_API   No longer supported; API selection is always automatic.
Macro definitions BOOST_WINDOW_PATH   No longer supported; native path format selection is always automatic.
Macro definitions BOOST_POSIX_PATH   No longer supported; native path format selection is always automatic.

Deprecation rationale

initial_path function

Full implementation of initial_path() would require support from the C++ runtime startup code, and that doesn't seem likely to happen. Depending on the user to call initial_path() at the beginning of main() is too error prone.  An equivalent function can trivially be provided by a user.
