String::FlexMatch - Flexible ways to match a string
version 1.100820
use String::FlexMatch; my $s = String::FlexMatch->new(string => 'foobar'); if ($s eq 'foobar') { # ... } $s = String::FlexMatch->new(regex => 'Error .* at line \d+'); if ($s eq 'Error "foo" at line 58') { # ... } $s = String::FlexMatch->new(code => 'sub { length $_[0] < 10 }'); # or: # my $s = String::FlexMatch->new(code => sub { length $_[0] < 10 }); if ($s ne 'somelongstring') { # ... }
Normally when trying to see whether two strings are equal, you use the eq operator. If you want to find out whether one string matches another more flexibly, you'd use a regular expression. And sometimes you have to call a subroutine with a string argument that will tell you whether that argument is interesting, i.e. matches in a broader sense.
eq
When running data-driven tests, you sometimes don't know beforehand which form of matching (eq, regex or code) you need. Take the following example:
use Test::More; use String::FlexMatch; use YAML; sub frobnicate { $_[0] + $_[1] } my $tests = Load do { local $/; <DATA> }; plan tests => scalar @$tests; for my $test (@$tests) { my $baz = frobnicate($test->{testarg}{foo}, $test->{testarg}{bar}); is($baz, $test->{expect}{baz}); } __DATA__ - testarg: foo: 2 bar: 3 expect: baz: 5 - testarg: foo: 21 bar: 34 expect: baz: !perl/String::FlexMatch regex: '\d+'
A setup like this was the reason for writing this class. If you find any other uses for it, please let me know so this manpage can be expanded with a few cookbook-style examples.
my $obj = String::FlexMatch->new; my $obj = String::FlexMatch->new(%args);
Creates and returns a new object. The constructor will accept as arguments a list of pairs, from component name to initial value. For each pair, the named component is initialized by calling the method of the same name with the given value. If called with a single hash reference, it is dereferenced and its key/value pairs are set as described before.
