◆ parse_i()

template<typename T_ >

std::enable_if<std::is_integral<T_>::value, typename std::make_unsigned<T_>::type>::type etiss::instr::parse_i	(	const char *	s,
		bool *	good = `0`
	)

this parser basically allows to write as a string hexadecimal values which will be appended as if it is one hexadecimal sequence and the "0x" prefix is replaced by a "<decimal number>x" [e.g.

12x] that defines the length in bits. e.g. "2xF 2x0 4xF" -> 0xCF

        syntax:
            string: definition [' ' string]
            definition: bit_count 'x' bit_value
            bit_count: digit [bit_count]
            digit: '0' | '1' | '2' | '3' | '4' | '5' | '6' | '7' | '8' | '9'
            bit_value: hdigit [bit_value]
            hdigit: '0' | '1' | '2' | '3' | '4' | '5' | '6' | '7' | '8' | '9' |
'A' | 'B' | 'C' | 'D' | 'E' | 'F'

bit_count is a decimal number that defines the length in bits of the definition. bit_value defines the values of the bits of the definition in hexadecimal format. the definitions are alwas placed at the least significant bits and are left shifted by definitions to the right from them. the total sum of bit_count occurences in a string must match the width of the return type otherwise an error message is printed the behaviour is undefined in case of a bit_value that has less bits than defined by the bit_count.

        example parsing process of "2xF 2x0 2xF 10x0":
            initial value:          0x0000
            parse 1. definition:    0x0003
            parse 2. definition:    0x000C
            parse 3. definition:    0x0033
            parse 4. definition:    0xCC00
