Thanks to Mathieu Othacehe, Cuirass now supports a subset of the HTTP
API of Hydra.  Currently the only interface to that is Emacs-Guix, but
we could/should write JavaScript code that does that; any takers?  :-)

So currently we can do:

  M-x guix-hydra-latest-builds

… and from there browse builds, view their status, etc.

We have yet to add support for viewing build logs (!) to ‘guix publish’
and/or Cuirass.

Agreed.  We’re not there yet, but that’s not insurmountable.

BTW, there’s the possibility of a master’s or internship project at the
MDC (Berlin, DE) with Ricardo around Cuirass:

I may also be able to recruit a master student or an intern at Inria
(Bordeaux, FR), possibly to work in this area.

If anyone is interested, please let us know!
