Method ExtractFolderFromPath

PathCopyCopy/src/PluginUtils.cpp:95–111

Given a path to a file or folder, will return the path to its parent folder. Ex: C:\Foo\Bar.txt => C:\Foo @param p_rPath Complete path on input, parent's path on output. @return true if we did find a parent path and returned it.

    // @return true if we did find a parent path and returned it.
    //
    bool PluginUtils::ExtractFolderFromPath(std::wstring& p_rPath)
    {
        // Find the last delimiter in the path and truncate path
        // as appropriate to return only the parent's path.
        std::wstring::size_type lastDelimPos = p_rPath.find_last_of(L"/\\");
        const bool found = (lastDelimPos != std::wstring::npos);
        if (found) {
            // We found a delimiter, clear everything after that
            // (and the delimiter as well). Exception: if we're left
            // with only a drive letter, keep the delimiter.
            if (lastDelimPos <= 2) {
                ++lastDelimPos;
            }
            p_rPath.erase(lastDelimPos);
        }
        return found;
    }

    //
    // Returns a list of a path's parents, in reverse order.
