Binary Bits Vector Token String Interpolator

Interpolator Syntax:

b"width'bin"

bin is a char sequence of '0', '1', and '?' (to indicate a bit bubble).
bin also allows separators of space ' ' or underscore '_' that are ignored.
width (with the following tag char ') is optional. If it's not specified, the width is determined by the length of the char sequence. Otherwise, the width is set as required. If the required width is longer than the char sequence length, then zeros are added as the MSBits. If the required width is shorter then the char sequence, it is accepted only if the MSBits it is truncating are zeros. Otherwise, a compilation error is generated.

Attributes

Returns

Bits vector token.

Note

The string interpolator currently does not accept external arguments with ${arg}

Example

 b"1"        //value = 1
 b"1000"     //value = 1000
 b"8'1000"   //value = 00001000
 b"3'0100"   //value = 100
 b"3'1100"   //error
 b"1?11"     //value = 1?11 (? is a bubble bit)
 b"11_00"    //value = 1100

Hexadecimal Bits Vector Token String Interpolator

Interpolator Syntax:

b"width'hex"

hex is a char sequence of '0'-'9','A'-'F','a'-'f','?' (to indicate a 4-bit bubble). Each character is equivalent to a 4-bits nibble.
hex also allows separators of space ' ' or underscore '_' that are ignored.
hex also supports a binary mode within {bin}, where bin is equivalent to the char sequence of the binary string interpolator (see b). So between 4-bit hex nibbles, it is possible to insert a binary bit sequence of any length that is not necessarily dividable by 4.
width (with the following tag char ') is optional. If it's not specified, the width is determined by the length of the char sequence. Otherwise, the width is set as required. If the required width is longer than the char sequence length, then zeros are added as the MSBits. If the required width is shorter then the char sequence, it is accepted only if the MSBits it is truncating are zeros. Otherwise, a compilation error is generated.

Attributes

Returns

Bits vector token.

Note

The string interpolator currently does not accept external arguments with ${arg}

Example

 h"1"        //value = 0001
 h"27"       //value = 00100111
 h"6'27"     //value = 100111
 h"5'27"     //error
 h"2?"       //value = 0010????
 h"F{00}F"   //value = 1111001111
 h"3_3"      //value = 00110011
