YAML :: Dumper没有引用标量字符串" - "

Question

问题:获取Perl的YAML::Dumper发出{key=>"-"}的key: "-",而不是key: -

我正在处理来自数据库行的哈希,用SOAP读取它们并将它们转换为YAML以供下一阶段使用.

第一阶段用Perl编写,并使用生成YAML YAML::Dumper.不幸的是,对于具有值的键,"-"裸连字符的发出没有任何引用:

$ perl -e 'use YAML;use YAML::Dumper; my $ydumper=YAML::Dumper->new(); print $ydumper->dump({key1=>1,key2=>"-",key3=>3});'
--- 
key1: 1
key2: -
key3: 3

下一阶段,读取上述内容并对其进行进一步操作,在Ruby中.原始破折号导致Ruby的YAML解析器变为varf:

$ ruby -rubygems -ryaml -e 'YAML.load($stdin.read);'  # assume the above piped in
/usr/share/ruby/vendor_ruby/psych.rb:205:in `parse': (<unknown>): block sequence entries are not allowed in this context at line 3 column 7 (Psych::SyntaxError)
    from /usr/share/ruby/vendor_ruby/psych.rb:205:in `parse_stream'
    from /usr/share/ruby/vendor_ruby/psych.rb:153:in `parse'
    from /usr/share/ruby/vendor_ruby/psych.rb:129:in `load'
    from -e:1:in `<main>'

我的问题很简单:我如何指示YAML::Dumper将短划线作为带引号的字符串发出？

谢谢!

我已经在github上为YAML :: Dumper 创建了一个pull请求,希望能够接受并解决这个问题.
