Hi! This is the friendly automated conda-forge-linting service.

I wanted to let you know that I linted all conda-recipes in your PR (recipe) and found some lint.

Here's what I've got...

For recipe:

• Failed to even lint the recipe, probably because of a conda-smithy bug :cry:. This likely indicates a problem in your meta.yaml, though. To get a traceback to help figure out what's going on, install conda-smithy and run conda smithy recipe-lint . from the recipe directory.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

@conda-forge/bot, the traitlets which is a dep has not been built for pypy yet, so I'm not sure why this PR was sent

[beckermr]

Edges out of date.

[isuruf]

@bollwyvl, @ocefpaf, is it okay to remove the ipykernel as a test dependency here because of the cycle? jupyter_core->ipykernel (for testing)->jupyter_client->jupyter_core

[ocefpaf]

It is @isuruf. In the past we removed and added it back. We don't have a more elegant way to handle cycles like those.

[isuruf]

@ocefpaf, done. Can you review?

[bollwyvl]

@conda-forge-admin please rerender

[bollwyvl]

Merged these in the wrong order: will work on fix

Hi! This is the friendly automated conda-forge-webservice. I tried to rerender for you, but it looks like there was nothing to do.

We don't have a more elegant way to handle cycles like those.

Perhaps for known cases like this, we introduce a jinja convention, e.g.

{% set cf_adding_new_build = True %}

test:
  requires:
    {% if not cf_adding_new_build %}
    - ipykernel
    {% endif %}
  commands:
    {% if not cf_adding_new_build %}
    - python -m pytest --pyargs jupyter_core -k "{{ skip }}"
    {% endif %}

then the bot would just have to know how to update the one boolean.

[bollwyvl]

recipe-lint reports no issues locally: provided it passes, LGTM, but will be away from my box for the balance of the day.

[beckermr]

@conda-forge-admin re-lint

Nice, good spell to know!
