Which dialect of Markdown is that from? I don’t believe “standard” Markdown has that in. What I use (and in my code process, but that’s a different story) using the <ins> HTML tag. (You can embed HTML in Markdown - for most Markdown processors.)

Typo “ctyles” of any consequence here?

Something for y'all to pick the bits out of...

A reply from @WorkflowHQ on Twitter contained the following...

"Also regarding sending images, Workflow can decode base64 encoded images."

Does this help us here? Can we encode images base64?

All this talk about iCloud illustrates one of the reasons why I'm not looking for a "write to file" solution.

Clipboard would be fine, though "trashing" the clipboard should only be done if necessary. It seems that it is.

To reveal a little more of the picture...

... My idea was to create a graphing Pythonista capability so Workflow might pass a CSV (file) into Pythonista and then do something with the graph (image) returned.

In essence I wanted to add graphing to Workflow. I would expect Pythonista would be a good way to do it.

Would Editorial do this better than Pythonista?

Thanks to all.

Workflow can have an image passed in to a "stage" in its pipeline. And I think it can have a stage output one.

While OK on the clipboard or persistent file front I wondered if the Pythonista stage could ingest and emit images directly.

Those of you who use Workflow know it can handle images.

Any idea how a Pythonista "stage" in the pipeline might pass an image back?

I've not tried it but 1Writer claims javascript support. Some people might like that: http://1writerapp.com/docs/js

Playing Devil's Advocate: What would this bring over existing IDE's on Mac?

Thanks to everybody for your responses so far.

I like the dictionary idea and @ccc had a particularly good thought in terms of stages being in a file, perhaps new line separated.

@ccc I'll be in touch with you during the week as you emailed me. For those who don't know, we both work for IBM - which has a positive stance on Open Source but some governance around it.
