dlc

dlc takes lispy template files (cl-template) as input and emits Graphviz DOT language files as output. It includes Common Lisp functions for creating nodes and edges and setting attributes on them.

If your normal workflow looks like this:

digraph makin_diagrams {
    #Author graphs via dot language
    Editor -> dot -> "Image Viewer";
}

... after dlc, it will look like this:

digraph makin_diagrams {
    #Author graphs via Common Lisp
    Editor -> dlc -> dot -> "Image Viewer";
}
