• Commented on Making YAML.pm, YAML::Syck and YAML::XS safer by default
  Yeah. The difference is, IMHO, that I wouldn't load data from untrusted sources via Data::Dumper or Storable. But for YAML that's not unusual, and people don't expect it to do potentially dangerous things by default....

Comment Threads

• Olaf Alders commented on I'm fully covered

  All of the coverage stats are generated by cpancover.com MetaCPAN is only returning the results provided by the cpancover API.

• Aristotle commented on I'm fully covered

  It doesn’t make any difference to users whether MetaCPAN runs the coverage checking itself or endorses the data generated by another service. The weight given to the data by MetaCPAN is the same.

• Ben Bullock commented on I'm fully covered

  Yes, metacpan is advertising these coverage results on their web site.

  For whatever reason, the coverage results are appearing inconsistently:

  https://metacpan.org/release/Table-Readable

  has no link but it's here:

  There are quite a lot of these glitches in the links, which don't seem to be formed correctly in many cases.

• Aristotle commented on Reusing data with YAML Anchors, Aliases and Merge Keys

  On newer Perls with refaliasing, it should be trivial to implement scalar aliases. YAML::PP could use that.

  On older Perls, Perl-based but non-pure-Perl YAML implementations can use Array::RefElem as a lightweight form of the refaliasing feature. Its drawback compared to refaliasing is that it only works on a slot in a container – which is a limitation when used in Perl code for aliasing scalars, but I think there is no possibility of encountering aliases in YAML in any other circumstance than inside slots within a container, so Array::RefElem sh…

• Aristotle commented on Reusing data with YAML Anchors, Aliases and Merge Keys

  I’m not yet sure that the implementation will be trivial

  Yes, I only meant trivial in the sense that you don’t have to resort to any trickery or low-level wizardry or XS or anything like that to create aliases of scalars to each other. A simple core-language construct is all you need. I did not mean to imply that the feature as a whole will be trivial to implement.

  With "slot in a container" you mean, that I can only add an alias to an array or hash element?

  Exactly. It lets you make the value of an array index or hash key into …
