charset=UTF-8 Content-Transfer-Encoding: 8bit I used __EXCEPTIONS to detect whether exceptions are supported. Apparently, this is a macro that is only used by libstdc++ (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64276). It’s much cleaner to use __cpp_exceptions as it is in the standard since C++98. Note that compiling the unit-tests with “-fno-exceptions” still does not work, because Catch uses throw internally.

Then - m_start + 1 + x < m_cursor - 1 must hold to loop indefinitely. This - can be rephrased to m_cursor - m_start - 2 > x. With the - precondition, we x <= 0, meaning that the loop condition holds - indefinitely if i is always decreased. However, observe that the value - of i is strictly increasing with each iteration, as it is incremented - by 1 in the iteration expression and never decremented inside the loop - body.

As - the loop body does not contain another loop, one of the called - functions must never return. The called functions are `std::strtoul` - and to_unicode. Neither function can loop forever, so the loop body - will never loop forever which contradicts the assumption that the loop - body does not terminate, q.e.d.\n - - Lemma: The loop condition for the for loop is eventually false.\n - - Proof (by contradiction): Assume the loop does not terminate. Due to - the above lemma, this can only be due to a tautological loop - condition; that is, the loop condition i < m_cursor - 1 must always be - true. Let x be the change of i for any loop iteration. Then - m_start + 1 + x < m_cursor - 1 must hold to loop indefinitely. This - can be rephrased to m_cursor - m_start - 2 > x. With the - precondition, we x <= 0, meaning that the loop condition holds - indefinitely if i is always decreased. However, observe that the value - of i is strictly increasing with each iteration, as it is incremented - by 1 in the iteration expression and never decremented inside the loop - body. Hence, the loop condition will eventually be false which - contradicts the assumption that the loop condition is a tautology, - q.e.d. - - @return string value of current token without opening and closing - quotes - @throw parse_error.102 if to_unicode fails or surrogate error - @throw parse_error.103 if to_unicode fails - */ - string_t get_string() const - { - assert(m_cursor - m_start >= 2); - - string_t result; - result.reserve(static_cast(m_cursor - m_start - 2)); - - // iterate the result between the quotes - for (const lexer_char_t* i = m_start + 1; i < m_cursor - 1; ++i) - { - // find next escape character - auto e = std::find(i, m_cursor - 1, '\\'); - if (e != i) - { - // see https://github.com/nlohmann/json/issues/365#issuecomment-262874705 - for (auto k = i; k < e; k++) - { - result.push_back(static_cast(*k)); - } - i = e - 1; // -1 because of ++i - } - else - { - // processing escaped character - // read next character - ++i; - - switch (*i) - { - // the default escapes - case 't': - { - result += "\t"; - break; - } - case 'b': - { - result += "\b"; - break; - } - case 'f': - { - result += "\f"; - break; - } - case 'n': - { - result += "\n"; - break; - } - case 'r': - { - result += "\r"; - break; - } - case '\\': - { - result += "\\"; - break; - } - case '/': - { - result += "/"; - break; - } - case '"': - { - result += "\""; - break; - } - - // unicode - case 'u': - { - // get code xxxx from uxxxx - auto codepoint = std::strtoul(std::string(reinterpret_cast(i + 1), - 4).c_str(), nullptr, 16); - - // check if codepoint is a high surrogate - if (codepoint >= 0xD800 and codepoint <= 0xDBFF) - { - // make sure there is a subsequent unicode - if ((i + 6 >= m_limit) or * (i + 5) != '\\' or * (i + 6) != 'u') - { - JSON_THROW(parse_error(102, get_position(), "missing low surrogate")); - } - - // get code yyyy from uxxxx\uyyyy - auto codepoint2 = std::strtoul(std::string(reinterpret_cast - (i + 7), 4).c_str(), nullptr, 16); - result += to_unicode(codepoint, codepoint2); - // skip the next 10 characters (xxxx\uyyyy) - i += 10; - } - else if (codepoint >= 0xDC00 and codepoint <= 0xDFFF) - { - // we found a lone low surrogate - JSON_THROW(parse_error(102, get_position(), "missing high surrogate")); - } - else - { - // add unicode character(s) - result += to_unicode(codepoint); - // skip the next four characters (xxxx) - i += 4; - } - break; - } - } - } - } - - return result; - } - - - /*! - @brief parse string into a built-in arithmetic type as if the current - locale is POSIX. - - @note in floating-point case strtod may parse past the token's end - - this is not an error - - @note any leading blanks are not handled - */ - struct strtonum - { - public: - strtonum(const char* start, const char* end) - : m_start(start), m_end(end) - {} - - /*! - @return true iff parsed successfully as number of type T - - @param[in,out] val shall contain parsed value, or undefined value - if could not parse - */ - template::value>::type> - bool to(T& val) const - { - return parse(val, std::is_integral()); - } - - private: - const char* const m_start = nullptr; - const char* const m_end = nullptr; - - // floating-point conversion - - // overloaded wrappers for strtod/strtof/strtold - // that will be called from parse - static void strtof(float& f, const char* str, char** endptr) - { - f = std::strtof(str, endptr); - } - - static void strtof(double& f, const char* str, char** endptr) - { - f = std::strtod(str, endptr); - } - - static void strtof(long double& f, const char* str, char** endptr) - { - f = std::strtold(str, endptr); - } - - template - bool parse(T& value, /*is_integral=*/std::false_type) const - { - // replace decimal separator with locale-specific version, - // when necessary; data will point to either the original - // string, or buf, or tempstr containing the fixed string. - std::string tempstr; - std::array buf; - const size_t len = static_cast(m_end - m_start); - - // lexer will reject empty numbers - assert(len > 0); - - // since dealing with strtod family of functions, we're - // getting the decimal point char from the C locale facilities - // instead of C++'s numpunct facet of the current std::locale - const auto loc = localeconv(); - assert(loc != nullptr); - const char decimal_point_char = (loc->decimal_point == nullptr) ?

Please note the [list of supported compilers](https://github.com/nlohmann/json/blob/master/README.md#supported-compilers). Some compilers like GCC 4.8 (and earlier), Clang 3.3 (and earlier), or Microsoft Visual Studio 13.0 and earlier are known not to work due to missing or incomplete C++11 support. Please refrain from proposing changes that work around these compiler's limitations with `#ifdef`s or other means. - Specifically, I am aware of compilation problems with **Microsoft Visual Studio** (there even is an [issue label](https://github.com/nlohmann/json/issues?utf8=✓&q=label%3A%22visual+studio%22+) for these kind of bugs). I understand that even in 2016, complete C++11 support isn't there yet. But please also understand that I do not want to drop features or uglify the code just to make Microsoft's sub-standard compiler happy. The past has shown that there are ways to express the functionality such that the code compiles with the most recent MSVC - unfortunately, this is not the main objective of the project. - Please refrain from proposing changes that would **break [JSON](http://json.org) conformance**. If you propose a conformant extension of JSON to be supported by the library, please motivate this extension.
