Update ecosystem.rst to include Pint

[znicholls]

We are working on upgrading pint to be compatible with pandas, see hgrecco/pint#684

I am guessing that the line in the docs,

If you’re building a library that implements the interface, please publicize it on Extension Data Types.

meant something like this pull request. If that's completely wrong, apologies.

I’ll take a look at pint#684; units support have been an often-requested feature for pandas.

[jreback]

I assume that this needs a new release of pint yes? pls indicate the minimum version here.

[znicholls]

We know the version number from hgrecco/pint#693 (comment), can I do anything else?

[znicholls]

@jreback @jbrockmendel any idea why this is failing..?

[jbrockmendel]

any idea why this is failing..?

Looks like a CI bug that was cleared up a couple days ago. Try rebasing?

[jreback]

can you merge master and update

[znicholls]

We're working on a new release of Pint (hgrecco/pint#693) but none of us can find the time right now, I hope to in January

[datapythonista]

CI is green now, is this ready to be merged, or are we waiting for the next Pint release?

[datapythonista]

@znicholls is this ready to be merged? or is a new Pint release or something else needed?

[znicholls]

or is a new Pint release or something else needed?

Up to you guys. It will be included in the next Pint release but maybe best wait given we're still a bit uncertain about how best to do it (Panda's pytest test suite isn't playing nice with Pint's unittest test suite and we don't understand why, see hgrecco/pint#741)

[datapythonista]

Ok, I see. Thanks for the clarification. I'll then close this PR for now, but please ping us when you update Pint, so we reopen it and discuss any needed change then.

[znicholls]

@datapythonista we have release pint-pandas on pypi (https://pypi.org/project/Pint-Pandas/). I've re-written the docs (see e.g. https://github.com/znicholls/pandas/blob/patch-1/doc/source/ecosystem.rst#pint-pandas) so can we re-open or make a new PR please?

FYI @hgrecco and @andrewgsavage

[datapythonista]

GitHub doesn't let me reopen this PR, since the branch has been forced pushed or recreated. Can you open a new PR please?

Also, the ecosystem was moved to the website, it's a different file now.

Thanks for the work on this.
