Timer API for motoko

[Jesse]

I’m eager to get remove the heartbeat() method from my code. I’m wondering if the new Timer API is available for Motoko yet and if so, where can I find the docs and an example?

Yes, it is. You’ll find everything here:

Is there a way to give precedence to certain function executions if there is an active queue in the canister's / subnet's execution?

Timers are in moc since 0.7.5 and are present in dfx 0.13.0-beta.1! Have fun! (See the thread of Heartbeat improvements / Timers [Community Consideration] - #138 by ggreif for the complete discussion.) Here is the documentation which hasn’t yet found its way into the portal, but will soon!

You can then import it with

import Timer "mo:base/Timer";

Also possibly helpful:

Importing Timer in Motoko, and using moc 0.7.5 with dfx 0.13.0-beta.2

I updated dfx to dfx 0.13.0-beta.2 to use Motoko Timer. I noticed a couple of things: import error [M0009], file ".mops/_github/base@moc-0.7.4/src/Timers/lib.mo" does not exist it seems to still be using moc 0.7.4 instead of 0.7.5. I’m told the binary of moc can be downloaded but is this expected behaviour? Also, not sure if it’s Timer or Timers. It seems to be used both ways: (motoko/timers.md at master · dfinity/motoko · GitHub) (motoko-base/Timer.mo at master · dfinity/motoko-base · Git…

You probably need to pull down an 8.x release of motoko and put it in your dfx cache for 0.12.1. There is an env variable for vessel that you can use as well…but I’m not sure what it is.
