Unfortunately, the current daemon protocol makes it hard to get such notifications, unless you parse its output (the “@ build-succeeded” lines) like I did in ‘wip-ui’. Perhaps we’ll have to do this parsing anyway, or just change the protocol altogether and have a “channel” mechanism like SSH to multiplex the number of communication channels on one connection. reepca, if you read this, that’s something to keep in mind. :-) Alternately, Cuirass could also periodically call ‘valid-path?’ for all the outputs of the pending builds (in a separate thread; note that the daemon connection cannot be shared among threads.) HTH, Ludo’.
