3 | 3 | //! The syntax is close to that of Posix format strings: |
4 | | -//! |
| 4 | +//! |
5 | 5 | //! ~~~~~~ |
6 | 6 | //! Format := '%' Parameter? Flag* Width? Precision? Type |
7 | 7 | //! Parameter := [0-9]+ '$' |

10 | 10 | //! Precision := '.' [0-9]+ |
11 | 11 | //! Type := [bcdfiostuxX?] |
12 | 12 | //! ~~~~~~ |
13 | | -//! |
14 | | -//! * Parameter is the 1-based argument to apply the format to. Currently not implemented. |
15 | | -//! * Flag 0 causes leading zeros to be used for padding when converting numbers. |
16 | | -//! * Flag # causes the conversion to be done in an *alternative* manner. Currently not implemented. |
17 | | -//! * Flag + causes signed numbers to always be prepended with a sign character. |

18 | 22 | //! * Flag - left justifies the result |
19 | | -//! * Width specifies the minimum field width of the result. By default leading spaces are added. |
20 | | -//! * Precision specifies the minimum number of digits for integral types and the minimum number |

| 24 | +//! leading spaces are added. |
| 25 | +//! * Precision specifies the minimum number of digits for integral types |

21 | 27 | //! of decimal places for float. |
