Question 1

How do I run Gronx tasker as a systemd service on Linux?

Accepted Answer

Create a systemd unit file that executes the tasker binary with your taskfile using the -file option. Set up log rotation for the -out file and ensure the service restarts on failure for basic reliability.

Question 2

Gronx vs robfig/cron: which is better for Go scheduling?

Accepted Answer

Gronx excels with zero dependencies, a built-in daemon, and support for cron seconds and tags, while robfig/cron is more established and integrates seamlessly with Go's context package. Choose Gronx for an all-in-one solution; robfig/cron for minimal library use within apps.

Question 3

Can Gronx handle daylight saving time changes correctly?

Accepted Answer

Yes, Gronx supports timezones via the Tz option, and cron expressions are evaluated based on local time. However, edge cases during DST transitions might require manual testing, as cron logic depends on the underlying system time.

Question 4

How to parse a cron expression with seconds in Gronx?

Accepted Answer

Use a 6 or 7-segment expression like '*/30 * * * * *' for every 30 seconds. Gronx automatically handles segments: 5 segments default to 0 seconds, while 6+ segments include seconds directly.

Question 5

Does Gronx support job retries on failure?

Accepted Answer

No, Gronx does not have built-in retry logic. You must implement retries manually within task functions or use external tools, as tasks only return exit codes and errors without automatic recovery.

Question 6

What's the best way to manage logs from Gronx tasker in production?

Accepted Answer

Use the -out option to direct outputs to a file, then set up log rotation (e.g., with logrotate) and monitoring. Combine with -verbose for debugging, but be mindful of log size in long-running daemons.
