I think it would be nice to have the option to dump a raw graphviz DOT file instead of the sppf.png for a few reasons:

• the file size is a lot smaller
• it's nice to be able to "do things" with the resulting tree in its structured form, rather than navigate the rendered bitmap
• it's only one extra (or no extra) line and could be optional, e.g. if you've turned on "debug" mode.

Any though

Everything in diagrams.css should be scoped to some wrapping css class, because as is it cannot be bundled with the rest of an app's css because of styles like this:

div {
    -webkit-touch-callout: none;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
}

svg {
    width: 100%;
}

Curre

Pull requests welcome!

Hi,
I don't know if its possible but maybe this can be somehow handled better:

If I have a grammar rule like so:

cppcmb_def(expr) = pc::pass
                   | (expr & match<Token::PLUS> & primary) [BinaryExpr::make]
                   | (expr & match<Token::MINUS> & primary) [BinaryExpr::make]
                   | primary
                   %= pc::as_memo_d;

And the met
