Fails to build with implicit conversion of anonymous access parameter

[jpds]

On a new empty project, AdaYaml appears to fail to build with errors:

$ alr init --bin example
...
$ alr with adayaml

Ah, looked through the commits since 0.3.0 and seems dd18ce4 is the fix for this - can we please have a new release?

Hate to say it, but this project is abandoned. It is an experimental implementation of a YAML 1.3 spec that never happened, uses a custom allocator that has bugs and is thus not in a state that I would recommend for production use.

I had a talk with ingy, one of YAML's authors, earlier this year where he told me he's working on autogenerating YAML implementations from a formal specification, including for Ada. I am not sure how far he's come with that but am basically waiting for this to happen so that I can link to his project and archive mine.

For these reasons, and the additional reason of me having already little time to maintain my more popular libraries, I'm afraid there will be no new release. I you need this code, I recommend putting it in your code base as there will be no more upstream activity. I also suggest to have a look at TOML instead which is in a better state and might fit your use-case.
