New way of dealing with Cobaya external packages

[JesusTorrado]

Hi,

We are updating the way Cobaya deals with external likelihoods. In the new implementation we will keep a more detailed list that can be programmatically used to have Cobaya install external likelihoods just with a mention by name (currently implemented but not released), have the external likelihoods appear in the drop-down boxes of the cosmo-generator (WIP), and hopefully other improvements (suggestions welcomed). The current WIP package is https://github.com/CobayaSampler/cobaya_cosmo

This also involves renaming some likelihoods, which in your case would mean calling it from Cobaya as cmb. act_dr6_lenslike, if you agree. It could simply be installed from cobaya as cobaya-install cmb. act_dr6_lenslike, with not additional input.

Would you please provide me with a one-sentence description of the likelihood that we can show in the new documentation?

Thanks!

Hey! I was wondering if there's been an update on this?

@JesusTorrado Sorry for missing this.
Calling this as cmb.act_dr6_lenslike sounds good to me. A one sentence description could be: "DR6.01 CMB lensing power spectrum likelihood for ACT and ACT+Planck"

Is there now a documented way to do this cleanly?

I did:

pip install act_dr6_lenslike
cobaya-install act_dr6_lenslike.ACTDR6LensLike

And it seems to work. Without pip beforehand, it crashes.
