custom generator in conan2

[xiaoliangwu]

Hi,
Do we still have custom generator in conan2?

https://docs.conan.io/1/reference/generators/custom.html#custom-generator

I check the https://docs.conan.io/1/conan_v2.html#conan2-migration-guide , but not sure which feature is the replacement

thanks

Hi @xiaoliangwu,

Thanks for the question. I'm pasting here the answer to a similar question in the Conan repository. This is something that we definitely need to improve in the Conan docs:

There are 2 things that replace the 1.X previous custom generators packages, depending on the use case:

• For the general case, explicit python_requires are recommended, that instantiate a helper explicitly in the consumers generate(). That means that the consumers should be conanfile.py with a generate() method. This method is good for many reasons:
  • Independent, private versioned dependencies: so every package can evolve at their pace, and doing a breaking change to the generator doesn't break all consumers at all
  • python_requires affect package_id of the consumers, so correct versioning can be used to trigger re-builds or to not trigger to save CI time
• Global generators, installable in the cache with conan config install will be added in 2.0.5: custom global generators in cache extensions/generators folder conan#13718
