C++ (Cpp) string_t::rfind Examples

Example #1

File: utils.cpp Project: dotnet/core-setup

pal::string_t strip_file_ext(const pal::string_t& path)
{
    if (path.empty())
    {
        return path;
    }
    size_t sep_pos = path.rfind(_X("/\\"));
    size_t dot_pos = path.rfind(_X('.'));
    if (sep_pos != pal::string_t::npos && sep_pos > dot_pos)
    {
        return path;
    }
    return path.substr(0, dot_pos);
}

Example #2

File: utils.cpp Project: dotnet/core-setup

pal::string_t get_filename_without_ext(const pal::string_t& path)
{
    if (path.empty())
    {
        return path;
    }

    size_t name_pos = path.find_last_of(_X("/\\"));
    size_t dot_pos = path.rfind(_X('.'));
    size_t start_pos = (name_pos == pal::string_t::npos) ? 0 : (name_pos + 1);
    size_t count = (dot_pos == pal::string_t::npos || dot_pos < start_pos) ? pal::string_t::npos : (dot_pos - start_pos);
    return path.substr(start_pos, count);
