Reaction directionality

[jchitpin]

Is it possible to preserve reaction directionality when plotting metabolic models with escherplot!() using arrows! instead of lines!?

Hi there,

Yes, that is a good idea! I will implement that this weekend :)

I just added arrows to the plot. Could you test it out and let me know what you think (v0.5.0)? Note, the arrows are not drawn at the tips of the reaction edges, but slightly further down, I think this looks better (and was substantially easier to implement). If the updated package doesn't work, lmk, Makie just released a new version as well, so there is a small chance that things could go wrong...

Thanks! I'm new to COBREXA so it will take me a bit to figure out where reaction directionality is stored in the model JSON file. Then I'll close off this issue.

I forgot to update to (v0.5.0) at first but can confirm the reaction arrows work and look great trailing behind the metabolite nodes. Manually specifying reversibility with reaction_directions also worked as expected. Thanks again!
