Automatic adjustment of coordinates

[psads-git]

Consider the following code. My question is: If one moves the second circle (circ2) vertically, one needs to manually adjust the following parameter of function line (rel: (0,2)): Can one have a more automatic way that adjusts that coordinate? Maybe resolving circ2 coordinates? But how?

#import "@preview/cetz:0.2.2"

#cetz.canvas({
  import cetz.draw: *

  set-style(circle: (radius: 0.8em))
  circle((0,0), name: "circ1")
  circle((2,2), name: "circ2")

  line("circ1.east", (rel: (0.6,0)), (rel: (0,2)), "circ2.west", 
     mark: (start: ">", fill: black))
})

I guess you want something dynamic like the following:

#import "@preview/cetz:0.2.2"
#set page(width: auto, height: auto)

#cetz.canvas({
  import cetz.draw: *

  set-style(circle: (radius: 0.8em))
  circle((0,0), name: "circ1")
  circle((2,2), name: "circ2")

  
  line("circ1",                             /* Intersection of a straight line between circ1.center and the next coordinate */
       ((), "-|", ("circ1", 50%, "circ2")), /* Move only horizontal to (circ1.x + circ2.x)/2 */
       ((), "|-", "circ2"),                 /* Move vertically to circ2.y */
       "circ2",                             /* Same as 1. but for circ2 */
      mark: (start: ">", fill: black))
})

With "circ2" at (2,2):

With "circ2" at (-3,1):

That is a perfect solution, @johannes-wolf! Thank you very much indeed!
