raku - 模块名称匹配

Question

我有一个模块名称列表，如 Str s，从 META6.json 中提取.具体来说，depends大批。这包含以下条目:

"Config::Parser::toml:ver<1.0.1+>",                                   
"Config:api<1>:ver<1.3.5+>",                                      
"Dist::Helper:ver<0.21.0+>",                                      
"Hash::Merge",                                                  
"Terminal::Getpass:ver<0.0.5+>",

我怎样才能最好地匹配单个条目？做 eq字符串匹配不够具体，如 Config不匹配 Config:api<1>:ver<1.3.5+>作为一个字符串。尝试使用 .starts-with 进行匹配也无法正常工作，如 Config:ver<1.3.5>不匹配 Config:api<1>:ver<1.3.5> .

use Zef::Distribution::DependencySpecification;

my $spec-ver-all     = Zef::Distribution::DependencySpecification.new("Foo::Bar");
my $spec-ver-zero    = Zef::Distribution::DependencySpecification.new("Foo::Bar:ver<0>");
my $spec-ver-one     = Zef::Distribution::DependencySpecification.new("Foo::Bar:ver<1>");
my $spec-ver-oneplus = Zef::Distribution::DependencySpecification.new("Foo::Bar:ver<1+>");
my $spec-ver-two     = Zef::Distribution::DependencySpecification.new("Foo::Bar:ver<2>");
my $spec-ver-three   = Zef::Distribution::DependencySpecification.new("Foo::Bar:ver<3>");

say $spec-ver-one.spec-matcher($spec-ver-all);         # True
say $spec-ver-one.spec-matcher($spec-ver-two);         # False
say $spec-ver-zero.spec-matcher($spec-ver-oneplus);    # False
say $spec-ver-oneplus.spec-matcher($spec-ver-oneplus); # True
say $spec-ver-three.spec-matcher($spec-ver-oneplus);   # True
