4.3.3 Agendas

- -

(use-modules (sly agenda))
-

- -

Agendas are used to schedule procedures to be called at distinct -points in time. One agenda, stored in the current-agenda -parameter, is active at any given time. A global agenda is initially -bound and is sufficient for most needs. When a separate scheduler is -required (see REPL for one such case), the parameter can be -rebound using parameterize or with-agenda form. -

Scheme Procedure: make-agenda: Create a new, empty agenda. -

- -

Scheme Syntax: agenda? obj: Return #t if obj is an agenda. -

- -

Scheme Variable: current-agenda: A parameter containing the current, dynamically scoped agenda object. -

- -

Scheme Procedure: agenda-time: Return the time of the current agenda. -

- -

Scheme Syntax: with-agenda agenda body …: Evaluate body with current-agenda bound to agenda. -

- -

Scheme Procedure: agenda-tick!: Increment time by 1 for the current agenda and run scheduled -procedures. -

- -

Scheme Procedure: agenda-clear!: Remove all scheduled procedures from the current agenda. -

- -

Scheme Procedure: schedule thunk [delay]: Schedule thunk to be applied after delay ticks of the -current agenda. The default delay is one tick. -

- -

Scheme Procedure: schedule-interval thunk interval: Schedule thunk to be applied every interval ticks of the -current agenda, forever. -

- -

Scheme Procedure: schedule-each thunk: Schedule thunk to be applied upon every tick of the current -agenda, forever. -

- -

Coroutines become particularly useful for game programming when -combined with the agenda. For example, a computer controller opponent -could periodically pause its AI algorithm to give the rest of the game -world a chance to do some processing. By using the wait -procedure, algorithms that span multiple ticks of game time can be -written in a straightforward, natural way. -

Scheme Procedure: wait delay: Abort the current coroutine prompt and schedule the continuation to be -run after delay ticks of the current agenda. -
