- * IPath
- * The Path's pathname is immutable and cannot be changed after creation.
+ * An IPath represents a filename, a directory or a filesystem path in general.
+ * It hides some of the operating system's specifics like path delimiters
+ * and encodings and provides an easy to use interface to handle them.
+ * Internally all paths are stored with the same path delimiter (PathDelim)
+ * and encoding (UTF-8). The transformation is already done AT THE CREATION of
+ * the IPath and hence calls to e.g. IPath.Equal() will not distinguish between
+ * Unix and Windows style paths.
+ *
+ * Create new paths with one of the Path() functions.
+ * If you need a string representation use IPath.ToNative/ToUTF8/ToWide.
+ * Note that due to the path-delimiter and encoding transformation the string
+ * might have changed. Path('one\test/path').ToUTF8() might return 'one/test/path'.
+ *
+ * It is recommended to use an IPath as long as possible without a string
+ * conversion (IPath.To...()). The whole Delphi (< 2009) and FPC RTL is ANSI
+ * only on Windows. If you would use for example FileExists(MyPath.ToNative)
+ * it would not find a file which contains characters that are not in the
+ * current locale. Same applies to AssignFile(), TFileStream.Create() and
+ * everything else in the RTL that expects a filename.
+ * As a rule of thumb: NEVER use any of the Delphi/FPC RTL filename functions
+ * if the filename parameter is not of a UTF8String or WideString type.
+ *
+ * If you need to open a file use TBinaryStream or TFileStream instead. Many
+ * of the RTL classes offer a LoadFromStream() method so ANSI Open() methods
+ * can be workaround.
+ *
+ * If there is only a ANSI and no IPath/UTF-8/WideString version and you cannot
+ * even pass a stream instead of a filename be aware that even if you know that
+ * a filename is ASCII only, subdirectories in an absolute path might contain
+ * some non-ASCII characters (for example the user's name) and hence might
+ * fail (if the characters are not in the current locale).
+ * It is rare but it happens.
+ *
+ * IMPORTANT:
+ * This interface needs the cwstring unit on Unix (Max OS X / Linux) systems.
+ * Cwstring functions (WideUpperCase, ...) cannot be used by external threads
+ * as FPC uses Thread-Local-Storage for the implementation. As a result do not
+ * call IPath stuff by external threads (e.g. in C callbacks or by SDL-threads).
