Hello. I've been getting familiar with Darcs recently and there is something I don't understand. The docs claim the dependency graph is being generated up to the latest non-dirty tag.

When I create a tag, I still can see the whole graph. What am I doing wrong?

BTW, is it normal that each patch depends also on the dependencies of its direct dependencies? The graph quickly gets messy because of this.

In both cases, I'm using `darcs show dependencies | dot -Tx11`.

vifon: its ok. you should not care of it

right? :)

Well, yes and no. It'd be pretty nice to visualize the dependencies in non-trivial repos. Especially when still getting familiar with Darcs.

With dependency chains of more than 3 patches, the graphs stop being planar, and then it only gets worse.

i just records changes. i am the most satisfied user.

vifon: did you tag and then record a new patch?

I suspect if you only have a tag at the head, then it doesn't just show you nothing

Yes, I tried recording a new patch afterwards.

Heffalump: vifon.einval.eu/upload/2020-10-13-6f0f47.png

Still the same thing.

I'll have a play later

Thanks.

So I just tried recording a couple of patches, then tagging. Before tagging, I see the two patches I recorded. After tagging, I just see the tag.

vifon: are you able to share your repo?

How did you know I was pushing it to my server this very minute?

didn't you know darcs has psychic powers?

Ah, of course.

darcs --make-them-gimme-the-repo

Do you want me to recreate the tag on my side? I've obliterated it already.

Heffalump: There you go: vifon.einval.eu/mpv-scripts

let me see what I get

so without any tagging of my own:

ganesh@Priory MINGW64 ~/temp/mpv-scripts

$ darcs show dependencies

digraph { graph [rankdir=LR]; node [imagescale=true]; 1 [label="TAG 1.0\n"]; 2 [label="test\n"];

}

what are you getting?

to be fair I am using a slightly old dev version of darcs, I'll need to update to 2.16.2 to be sure

Yeah, I'm on 2.16.2.

BTW, can you obliterate the tag and show me your graph then? Rendered, preferably. I'm wondering whether the graph edges are as intended at all.

I don't have dot installed on my Windows machine. But I think I must be running a different algorithm, because I see nodes numbered in numerical order whereas you are getting ones with patch hashes.

So I suspect something got broken recently.

Let me fetch the 2.14.5 then…

pastebin.com/v9UpUVY1 is what I see

Well, that's *much* clearer!

I should go to bed, but I'll try to track down the culprit tomorrow.

Thanks a lot! Goodnight!

Heffalump: Curious. 2.14.5 fetches a GraphViz Haskell library. vifon.einval.eu/upload/2020-10-14-1455cc.png

yeah, I think part of the reason for things changing was that dependency was getting painful because it wasn't updated

A quick unrelated question: how can I force `darcs log` to not invoke the pager and/or keep the colors?

Yeah, definitely something with 2.16, it's the same as yours on 2.14.
