# HG changeset patch # User Kyle Lippincott # Date 2018-10-16 11:59:36 # Node ID 2e97640c598ef5515118f5f736f5fbff4eef07d1 # Parent e7d3e56fa32e7c5577f8b7694e48833ea4226306 graphmod: remove support for graph lines mixing parent/grandparent styles (BC) Currently, if the configuration for a graph edge draw style has multiple bytes (at least on python2), it is interpreted as "this is a request to draw the line partially in the style of the parent, partially in the style of the grandparent". This precludes the configuration handling unicode characters (which trigger the `len > 1` check, at least on python2), and I believe was part of the reason that beautifygraph was written the way it was. Talking with the person who implemented this, it appears to have been to achieve feature parity with the rendering of the smartlog extension. I suspect that this isn't actually used outside of that situation, so I think that we can remove it without much issue. This will make it so that multi-character edges are possible, and render any existing configuration that uses this feature with these multiple characters. This is *not* going to adjust the width of everything to make it line up correctly, please see the test that's being modified in this changeset for an example of how the previous configuration now renders. Note also that the previous configuration seems to have been broken, or at least it was behaving in a really non-obvious way - it was avoiding the grandparent character(s) when it should have been displaying them! This is why so many "!" characters changed to "3."; I don't know if this was intentional.
