Other node names that cause this:
- node
- edge
- subgraph
- digraph
The first error message is coming from graphviz when it parses the graph output.
Error: <stdin>: syntax error in line 7 near '}'
I suspect all DOT keywords would cause this failure.
from psgraph.
What do you think about changing this section in Format-Value?
# Normal value, no quotes
'^[\w]+$'
{
'"{0}"' -f $value
}
I ran through some quick tests and it seems to resolve the issue.
from psgraph.
There are two scenarios that I would need to look at that I may as well document here and get some tests added.
The first one is setting note (or edge) attribute defaults.
Graph testGraph {
node @{shape='rect'}
node 'cat'
node 'dog'
} | Export-PSGraph -ShowGraph
If that first node gets quotes around it, it becomes a real node instead of defining the attributes for the other nodes. In one case you would get two squares and in the other, you would get one square and two circles.
I did notice that custom format scripts are causing issues like this too, so I opened #32 to track it. I'm going to look to see how easy it would be to pull that special case out of the normal format logic.
The second is edges to record nodes.
graph g {
node @{shape='record'}
node struct1 @{shape='record';label=" left|<f1> middle|<f2> right"}
node struct2 @{shape='record';label="<f0> one| two"}
node struct3 @{shape='record';label="hello\nworld |{ b |{c|<here> d|e}| f}| g | h"}
edge struct1:f1 -to struct2:f0
edge struct1:f2 -to struct3:here
} | Export-PSGraph -ShowGraph
The edge in this example may need some more analysis. I don't have any documentation on record nodes and edges, but I want to maintain that underlying engine compatibility.
I am tempted to add a way to turn that off though and that may be a better discussion in another thread. As it stands, it gets in the way of edges to uri
and server:port
named nodes.
