[question] How to add dynamically option to recipe

[madebr]

Hello,

In conan-io/conan-center-index#2097, I'm attempting to add components support to boost, using extracted data from the boost sources (using yamls).

This means that the options of the boost recipe depend on the contents of a yml.
The yml depends on the version.

This recipe works fine when using as conan create . boost/1.74.0@,
but fails when used with conan-package-tools: conan-io/conan-center-index#3159 (comment)
c3i/conan-package-tools fails because it cannot find the yml:
No such file or directory: '/home/conan/w/cci_PR-2097/recipes/boost/all/dependencies/dependencies-None.yml'

So my question is how to dynamically add options to recipes (in this case extracted from the yml) instead of adding all possible options and removing the ones that are not supported.

So, looking at the code, the only thing missing is the version of the dependency to be able to format the yaml file name?

It's the version of the package itself that is being initialized too late. The options depend on the version.

I find my approach to adding dynamic options rather hacks (conan package tools don't support it). I was wondering whether there's a better way.

Closing this issue as it seems to be working fine and we didn't found a better way of doing so. If conan-package-tools support is still required, please open a new issue there. Thanks!
