FR: Graphviz dot language support, ignore Graphviz generated SVGs

[ajkq]

Is it possible to add support for Graphviz files (dot graph description language; extension .gv or .dot)?

It would also be great if Graphviz-generated SVG files could be ignored, especially if the .gv source files are in the same folder and have the same name.

SVGs have the following header:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN"
 "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<!-- Generated by graphviz version 2.47.3 (20210619.1520)
 -->

OS: macOS 11.4
scc version 3.0.0

So pretty much XML then. Yep that should be possible.

Ignores... could be done though .ignore files which would be my preference, as someone may want to actually include it in the count.

The .gv/.dot source files are not xml.
A graph looks like this:

digraph {
    subgraph cluster_0 {
        label="Subgraph A";
        a -> b;
        b -> c;
        c -> d;
    }

    subgraph cluster_1 {
        label="Subgraph B";
        a -> f;
        f -> c;
    }
}

Here are a few examples

Oh right... I used them in the original post about scc... how the heck could I make that mistake. As for the ignored, yes that's totally possible now actually.

Please forgive me, I have been off the coffee for the last two weeks and still trying to wake my brain up :)

Added into mainline so if you build from there and run it it should pick up .gv/.dot files. However I put it under the name "DOT" in accordance with what wikipedia calls it https://en.wikipedia.org/wiki/DOT_(graph_description_language) and not graphviz as the name. Hoping that works for you.

Let me know if you get odd results, but my initial checks showed it to be fine.
