Boost.RegexSed-Style Format String Syntax |
|
Sed-style format strings treat all characters as literals except:
| & | The ampersand character is replaced in the output stream by the the whole of what matched the regular expression. Use \& to output a literal '&' character. |
| \ | Specifies an escape sequence. |
An escape character followed by any character x, outputs that character unless x is one of the escape sequences shown below.
| Escape | Meaning |
| \a | Outputs the bell character: '\a'. |
| \e | Outputs the ANSI escape character (code point 27). |
| \f | Outputs a form feed character: '\f' |
| \n | Outputs a newline character: '\n'. |
| \r | Outputs a carriage return character: '\r'. |
| \t | Outputs a tab character: '\t'. |
| \v | Outputs a vertical tab character: '\v'. |
| \xDD | Outputs the character whose hexadecimal code point is 0xDD |
| \x{DDDD} | Outputs the character whose hexadecimal code point is 0xDDDDD |
| \cX | Outputs the ANSI escape sequence "escape-X". |
| \D | If D is a decimal digit in the range 1-9, then outputs the text that matched sub-expression D. |
