can these python 'placeholder' functions be generated from a spec?

[martinRenou]

Yes I had it in mind, did not find a spec though

[maartenbreddels]

It seems https://github.com/vega/vega/blob/master/docs/docs/expressions.md is manually written and includes HTML, so it doesn't seem like an easy route.

[martinRenou]

True.. Maybe we could open an issue in vega-expressions

[maartenbreddels]

Indeed, since I have no idea where they are coming from, could you open an issue an ping me?

[martinRenou]

Sure :)
