View the history of mercury with blurry straight line development

Question

I am interested to see the topology of my branches, ideally beautiful (a la graphlog). For example, I want to see how many (open) branches there are when they split, the last time they merge with each other, etc. Etc. I am not interested in all the mergers between them, as well as direct development on each branch.

This is useful when viewing forks on a bit baget, for example. The guitar graph Github helps, but often the branch structure is recessed by direct development and / or frequent mergers.

I thought maybe I could use revsets like

hg glog --rev "head() or merge() or branch_points()" 

but then glog shows all the changes between them, not to mention that I could not figure out how to specify branch_points (), that is, revisions that have more than one child.

Is there an extension to mercury (or other DVCS) that can bring my desires closer? If not, what is the best way to get this information?

Answer 1

The following patch adds a branch point to the branch in Mercurial. Currently, it only applies to Mercurial 2.2, but there it works well.

I don’t know if I can quickly click on the switch. You can go to the mailing list and suggest getting ready for inclusion (which will save me from this job).

Answer 2

  $ hg log -Gr "merge () + head ()"
