=head1 DESCRIPTION |
45
|
|
|
|
|
|
|
|
46
|
|
|
|
|
|
|
String::Scanf supports scanning strings for data using formats |
47
|
|
|
|
|
|
|
similar to the libc/stdio sscanf(). |
48
|
|
|
|
|
|
|
|
49
|
|
|
|
|
|
|
The supported sscanf() formats are as follows: |

The exponent has an optional plus or minus sign, and the C may also be C. |
86
|
|
|
|
|
|
|
|
87
|
|
|
|
|
|
|
The various borderline cases like C and C are not recognized. |

=item %s |

|

A non-whitespace string. |

|
|
|
|
|
|
|
=item %c |
94
|
|
|
|
|
|
|
|
95
|
|
|
|
|
|
|
A string of characters. An array reference is returned containing |
96
|
|
|
|
|
|
|
the numerical values of the characters. |
97
|
|
|

|
=item %% |
99
|
|
|
|
|
|
|
|
100
|
|
|
|
|
|
|
A literal C<%>. |

103
|
|
|
|
|
|
|
|
104
|
|
|
|
|
|
|
The sscanf() formats [pnSC] are not supported. |
105
|
|
|
|
|
|
|
|
106
|
|
|
|
|
|
|
The C<%s> and C<%c> have an optional maximum width, e.g. C<%4s>, |
107
|
|
|
|
|
|
|
in which case at most so many characters are consumed (but fewer |
108
|
|
|
|
|
|
|
characters are also accecpted). |
109
|
|
|
|
|
|
|
|
110
|
|
|
|
|
|
|
The numeric formats may also have such a width but it is ignored. |
111
|
|
|
|
|
|
|
|
112
|
|
|
|
|
|
|
The numeric formats may have C<[hl> before the main option, e.g. C<%hd>, |
113
|
|
|
|
|
|
|
but since such widths have no meaning in Perl, they are ignored. |
114
|
|
|
|
|
|
|
|
115
|
|
|
|
|
|
|
Non-format parts of the parameter string are matched literally |
116
|
|
|
|
|
|
|
(e.g. C<:> matches as C<:>), |
117
|
|
|
|
|
|
|
expect that any whitespace is matched as any whitespace |
118
|
|
|
|
|
|
|
(e.g. C< > matches as C<\s+>). |
119
|

=head1 WARNING |
121
|
|
|
|
|
|
|
|
122
|
|
|
|
|
|
|
The numeric formats match only something that looks like a number, |
123
|
|
|
|
|
|
|
they do not care whether it fits into the numbers of Perl. In other |
124
|
|
|
|
|
|
|
words, C<123e456789> is valid for C, but quite probably it |
125
|
|
|
|
|
|
|
won't fit into your Perl's numbers. Consider using the various |
126
|
|
|
|
|
|
|
Math::* modules instead. |
