Support for adjusting to VS Code theme

[mforkel]

I use Graphviz Interactive Preview to display dot graphs created by quilt graph. These graphs do not contain any color or font information. That results in black nodes and edges on a white background, which does not match well with most VS Code color themes.

Currently, I adapt the graph source with gvpr and a program file like

BEG_G {
    bgcolor="#1e1e1e"       // editor.background
}
N {
    color="#d4d4d4",        // editor.foreground
    fontcolor="#d4d4d4",    // editor.foreground
    fontname="Consolas",
    fontsize="14pt"
}
E {
    color="#d4d4d4",        // editor.foreground
    fontcolor="#d4d4d4",    // editor.foreground
    fontname="Consolas",
    fontsize="14pt"
}

That is not a real solution. The actual color values are not available to an extension or to the user, so they can't be provided programmatically or in the configuration. But color and font information is available through CSS variables in webviews.

Would it be possible to add an option for the display of graphs to change the default values for graph display to those of the current VS Code theme?

That's something I already tried in . However, it needs some more polishing, which I canˋt do at the moment.

Just discovered your own issue #72. Sorry I missed it. I guess that's what you're referring to in you reply ("tried in ")?

Exactly. Unfortunately it currently looks like this if the nodes have the attribute "filled":
