Add ll_convert<TO, FROM> template, used as (e.g.): ll_convert<std::string>(value_of_some_other_string_type); There is no generic template implementation -- the template exists solely to provide generic aliases for a bewildering family of llstring.h string- conversion functions with highly-specific names. There's a generic implementation, though, for the degenerate case where FROM and TO are identical. Add ll_convert<> specialization aliases for most of the string-conversion functions declared in llstring.h, including the Windows-specific ones involving llutf16string and std::wstring. Add a mini-lecture in llstring.h about appropriate use of string types on Windows. Add LL_WCHAR_T_NATIVE llpreprocessor.h macro so we can detect whether to provide separate conversions for llutf16string and std::wstring, or whether those would collide because the types are identical. Add inline ll_convert_wide_to_string(const std::wstring&) overloads so caller isn't required to call arg.c_str(), which naturally permits an ll_convert alias. Add ll_convert_wide_to_wstring(), ll_convert_wstring_to_wide() as placeholders for converting between Windows std::wstring and Linden LLWString, with corresponding ll_convert aliases. We don't yet have library code to perform such conversions officially; for now, just copy characters. Add LLStringUtil::getenv(key) and getoptenv(key) functions. The latter returns boost::optional<string_type> in case the caller needs to detect absence of a given environment variable rather than simply accepting a default value. Naturally getenv(), which accepts a default, is implemented using getoptenv(). getoptenv(), in turn, is implemented using an underlying llstring_getoptenv(). On Windows, llstring_getoptenv() returns boost::optional<std::wstring> (based on GetEnvironmentVariableW()), whereas elsewhere, llstring_getoptenv() returns boost::optional<std::string> (based on classic Posix getenv()). The beauty of generic ll_convert is that the portable LLStringUtilBase<T>:: getoptenv() template can call the platform-specific llstring_getoptenv() and transparently perform whatever conversion is necessary to return the desired string_type. Add windows_message<T>(error) template, with an overload that implicitly calls GetLastError(). We provide a single concrete windows_message<std::wstring>() implementation because that's what we get from Windows FormatMessageW() -- everything else is a generic conversion to the desired target string type. This obviates llprocess.cpp's previous WindowsErrorString() implementation -- reimplement using windows_message<std::string>(). |
