6 Text::Sprintf::Named - sprintf-like function with named conversions

12 use Text::Sprintf::Named;
13 my $formatter =
15 Text::Sprintf::Named->new(
16 {fmt => "Hello %(name)s! Today is %(day)s!"}
17 );
18 # Returns "Hello Ayeleth! Today is Sunday!"
20 $formatter->format({args => {'name' => "Ayeleth", 'day' => "Sunday"}});
21 # Returns "Hello John! Today is Thursday!"
23 $formatter->format({args => {'name' => "John", 'day' => "Thursday"}});
24 # Or alternatively using the non-OOP interface:
26 use Text::Sprintf::Named qw(named_sprintf);
28 # Prints "Hello Sophie!" (and a newline).
30 print named_sprintf("Hello %(name)s!\n", { name => 'Sophie' });
31 # Same, but with a flattened parameter list (not inside a hash reference)
33 print named_sprintf("Hello %(name)s!\n", name => 'Sophie');
34
36 Text::Sprintf::Named provides a sprintf equivalent with named
37 conversions. Named conversions are sprintf field specifiers (like "%s"
38 or ""%4d"") only they are associated with the key of an associative
39 array of parameters. So for example "%(name)s" will emit the 'name'
40 parameter as a string, and "%(num)4d" will emit the 'num' parameter as
41 a variable with a width of 4.

45
47 my $formatter = Text::Sprintf::Named->new({fmt => $format})
48 Creates a new object which formats according to the $format format.
49 $formatter->format({args => \%bindings})
51 Returns the formatting string as formatted using the named parameters
52 pointed to by the "args" parameter.
53 $self->calc_param({%args})
55 This method is used to calculate the parameter for the conversion. It
56 can be over-rided by subclasses so it will behave differently. An
57 example can be found in "t/02-override-param-retrieval.t" where it is
58 used to call the accessors of an object for values.
59 %args contains:
61 · named_params
63 The named paramters.
65 · name
67 The name of the conversion.
69 named_sprintf($format, {%parameters})
71 named_sprintf($format, %parameters)
72 This is a convenience function to directly format a string with the
73 named parameters, which can be specified inside a (non-blessed) hash
74 reference or as a flattened hash. See the synopsis for an example.

114 The (possibly ad-hoc) regex for matching the optional digits+symbols
115 parameters' prefix of the sprintf conversion was originally written by
116 Bart Lateur (BARTL on CPAN) for his String::Sprintf module.
117 The syntax was borrowed directly from PythonXs "%" operator when used
119 with its dictionaries as the right-hand argument. A quick web search
120 did not yield good documentation about it (and I came with the idea of
121 a named sprintf without knowing that Python had it, only ran into the
122 fact that Python had it by web-searching).
123
125 Text::sprintfn is a newer module which only provides a procedural
126 interface that allows one to mix positional and named arguments, with
127 some other interesting features.
128 String::Formatter is a comprehensive module that allows one to define
130 custom sprintf-like functions (IXm not sure whether it has named
131 conversions). Its license is the GNU General Public Licence version 2
132 (GPLv2), which is both restrictive and incompatible with version 3 of
133 the GPL and with many other open-source licenses.
134 String::Sprintf appears to allow one to provide custom sprintf/printf
136 formats (without providing named conversions).
137 For the lighter side, there is Acme::StringFormat, which provides a "%"
139 operator to format a string.
