ANN: Dogelog Player 1.0.4 (Time-Out Alarm)

Dear All,

We are happy to announce a new edition of the Dogelog player:

- library(markup):
To facilitate the generation of HTML texts inside the browser, format/2 now accepts ~a for HTML attributes and ~c for URL components. Further there are predicates tag/[1,2] that switch the stream to raw mode instead XML encoding, so that tags can be written.

- New setup_once_cleanup/3:
Since a stop button and Ctrl-C key started to work, we needed to think of a robust setup and cleanup method. We noticed a Logtalk idiom in the wild which we extended by signal shielding and exception chaining. Also there is a novel catch/3 which matches the head of a chain.

- New time_out/2:
There is also new predicate time_out/2 to abort a goal after some delay. Implemented via the event loop of JavaScript respectively Python. The predicate is not yet perfect, for example it cannot prematurely abort a sleep/1, but it can already abort where the Prolog interpreter yields or auto-yields.

Have Fun!
