Drake graph does not show tags?

[kavink]

I have a simplistic drake, which just is run using tags. Whenever i try to create a --graph from it, It comes out empty, I was expecting to atleast see something. Please can you let me know if this is a bug or its behaving as expected ?

%initialize <-
    "Start from here"

%export <- %initialize
    echo "Do some stuff"

%build-complete <- %initialize, %export
    echo "Dont"

hi @kavink , what does "comes out empty" mean exactly? Is there a .png file generated, and if so, would you mind attaching to this ticket? Also, please show us the exact command you're using to run.

png is empty.

$ cat workflows/drake/test.d 
%initialize <-
    echo "start"

%export-1 <- %initialize
    echo "do some stuff"

%export-2 <- %export-1
    echo "do some stuff"

%build-complete <- %initialize, %export-1, %export-2
    echo "Done"

$ drake -w workflows/drake/test.d  --graph "+^%initialize"
Image saved to drake.png
$ drake -w workflows/drake/test.d  --graph=dot "+^%initialize"
DOT file saved to drake.dot
$ drake -w workflows/drake/test.d  --preview "+^%initialize"
The following steps will be run, in order:
  1: %initialize <-  [forced (via tag)]
  2: %export-1 <- %initialize [forced]
  3: %export-2 <- %export-1 [forced]
  4: %build-complete <- %initialize, %export-1, %export-2 [forced]

image attached below is empty.

dot file looks like

digraph {
graph[dpi=100, rankdir=TP]
node[fontname="Monospace"]
edge[fontname="Monospace"]

}

--graph doesn't really pay attention to tags, only files that are built. it's not that exciting to get a graph of tags, because they need to be rebuilt iff you specified them.

[kavink]

@amalloy It does help to know the DAG, because now if i need to show all stages in pipeline, The tag stages are missing , which means, need to manually create the dot graph looking at the drake workflow file. This becomes complicated if we have like 20-30 tags in the pipelines.

Any plans --graph will show all stage execution steps ?

Just started to use drake for out data workflows. Tags are great, but hitting the same limitation of not able to visualize tagged steps along with file based steps. Graph is broken with out tags.

Thoughts?
