How to fetch kwalitee metrics?

[szabgab]

I could not find this in the docs of MetaCPAN::Client. If it is possible, it would be nice to have an example.

That information is not included in the API, so the client can't give it to you.

[szabgab]

Would it be a good idea to mention this in the POD so others who might look for this will be able to find this information easily? I'd be glad to send a PR.

Is there an API for Kwalitee metrics that we could get the scores from?

[szabgab]

Oh, I thought it was part of MetaCPAN. I just realized that the kwalitee links on MetaCPAN lead to cpants.cpanauthors.org and the data is not coming from MetaCPAN. My bad. Sorry.

[oalders]

That clears it up. I was confused. 😄

[szabgab]

If we are talking about this, why is there no (easy) way to get the data from cpants? Was that some refusal or just lack of tuits?

[oalders]

I don't think we've ever tried to do this. Maybe it's possible? I believe @charsbar would be the person to answer this.

Visit https://api.cpanauthors.org/v5 .

Adding .json at the end of a CPANTS URL would also give you some data but the structure may change at any time.

@charsbar Thanks, I am working on it. I think I found a few issues with the API and reported them on https://github.com/cpants/www-cpants is that the right place do so?

I've managed to fetch all the data from CPANTS and display the overall metric on CPAN Digger https://cpan-digger.perlmaven.com/ There were about 1,000 of the 40,000 distributions that returned some error indicating a crash on the server.

From https://cpants.cpanauthors.org/dist/$dist I can retrieve metrics like coverage and kwalitee, which are not available from https://api.cpanauthors.org/v5/dist/$dist/overview, so I like to see your approach.
I use https://github.com/Tux/Release-Checklist/blob/master/scripts/makewww.pl to generate https://tux.nl/perl.html
To you that might not show as fancy, but I like it better. I'm open to improvements and modernizations content-wise (not presentation-wise). My CI part is outdated

Reading the docs, I'd expect https://api.cpanauthors.org/v5/kwalitee/$dist to return me those metrics, but all I get is errors: {"errors":[{"message":"Expected object - got string.","path":"\/errors\/0"}],"status":400}

@Tux Thanks for you comment. Your page looks nice.

I am fetching data from https://api.cpanauthors.org/v5/release/$author/$dist/metadata but actually currently I am only interested and only display the core_kwalitee field which, if I understand correctly, is an aggregation of all the kwalitee metrics.
