And while I was hacking this, two more improvements in 1.3.2:

* kdrfc now has a -h/—-html flag that generates html alongside the txt (use --no-txt to suppress the latter).

So a typical thing you might do now is:

   kdrfc -3h foo.md
   open foo.html

I still need to hack the remote xml2rfc support, though, -rh gives an error at the moment.

* There is now experimental support for generating artsets.

In markdown, this is a code block of type “goat”.
Special-casing this type, kdrfc then calls goat and svgcheck (which both must be in the path(*)) to generate SVG for use in the HTML, keeping the UTF-8 art (“ascii-art”) for use in the TXT.

Until I have learned how to properly shut up svgcheck (which seems to ignore its -q option), this will be a bit chatty.

If you want support for other ascii-art-to-SVG processors, please tell us.

I really want to do a version of mscgen (what UML calls sequence diagrams) next; if you have a favorite that can generate SVG that svgcheck groks and is reasonably easy to install, I’d like to know.

UML Flow charts?  Hand-drawn diagrams?  DOT/Graphviz?  Gantt diagrams?  Music?
Railroad charts?  You name it, you got it (as long as an SVG processor exists).

Grüße, Carsten

(*) The gem install will not try to find and install that for you.
Thomas has documented in his svg-test draft how to get these:

$ go get github.com/blampe/goat
$ pip install svgcheck

Of course you need go and python, which you might get via:

$ brew install go
(do read the hints output after install)
$ brew install python
