How can I check if my triggers.dar file is linked with my main dar file?

Sometimes I’ll create a new ledger from the daml hub console and re upload the triggers.dar, and the main dar file, and once I’ve set up the triggers, I realize they are not getting triggered. (while they previously were working fine.)

How can I check that the trigger.dar is in fact referencing the main dar file correctly? instead of just guessing and rebuilding everything each time? Thanks!

Your best bet is probably to check package ids via daml damlc inspect-dar. Specifically find the main package id of your template DAR via daml damlc inspect-dar --json path/to/template.dar | jq '.main_package_id' (if you don’t have jq, just look at the main_packageid field in the output yourself.

Then check that the trigger dar depends on this by running daml damlc inspect-dar --json poc6/.daml/dist/canton-coin-0.1.0.dar | jq '.packages | keys' and checking that the package id you got from step 1 is part of that.
