Changing arrow size after placement #15

Closed maxsnew closed 6 years ago

maxsnew commented 6 years ago

Is there a way to stretch/shrink arrows after you've placed them?

yishn commented 6 years ago

No, is there any way to do that in tikzcd?

maxsnew commented 6 years ago

I'm not sure what you mean, in latex it would usually require adding newlines or &s. In your jsx-tikzcd README example, this would correspond to changing the from or to properties of an Edge.

I naturally just tried to grab the end of an arrow and drag it to make it longer/shorter so that's what I'm imagining as a feature. This would be very useful if you need to make an existing diagram larger/smaller without remaking the arrow altogether.

I completely agree. I do this so often while writing papers with diagrams to things to fit.

@maxsnew You can drag the grid cells of the corresponding arrow around to make arrows longer/shorter.

maxsnew commented 6 years ago

@yishn ah great that does most of what I want. The only case it doesn't cover is when I want to shrink/stretch one arrow whose head is the same as another without affecting the other arrow.

You could work around this if you also had cut/paste, which is a feature I'd like even more.

Why would you want to do that? Don't you want the arrows to preserve source and target?

maxsnew commented 6 years ago

I can see wanting to do it if it was a mistake, or if you wanted to separate one diagram into two. But probably not a common thing to need.

yishn commented 6 years ago

Alright, I'm closing this as this has been resolved.
