## Features
- **Job types**: Jobs can be run at various intervals.
- [**Duration**](https://pkg.go.dev/github.com/go-co-op/gocron/v2#DurationJob):
Jobs can be run at a fixed `time.Duration`.
- [**Random duration**](https://pkg.go.dev/github.com/go-co-op/gocron/v2#DurationRandomJob):
Jobs can be run at a random `time.Duration` between a min and max.
- [**Cron**](https://pkg.go.dev/github.com/go-co-op/gocron/v2#CronJob):
Jobs can be run using a crontab.
- [**Daily**](https://pkg.go.dev/github.com/go-co-op/gocron/v2#DailyJob):
Jobs can be run every x days at specific times.
- [**Weekly**](https://pkg.go.dev/github.com/go-co-op/gocron/v2#WeeklyJob):
Jobs can be run every x weeks on specific days of the week and at specific times.
- [**Monthly**](https://pkg.go.dev/github.com/go-co-op/gocron/v2#MonthlyJob):
Jobs can be run every x months on specific days of the month and at specific times.
- **Concurrency Limits**: Jobs can be limited individually or across the entire scheduler.
- [**Per job limiting with singleton mode**](https://pkg.go.dev/github.com/go-co-op/gocron/v2#WithSingletonMode):
Jobs can be limited to a single concurrent execution that either reschedules (skips overlapping executions)
or queues (waits for the previous execution to finish).
- [**Per scheduler limiting with limit mode**](https://pkg.go.dev/github.com/go-co-op/gocron/v2#WithLimitConcurrentJobs):
Jobs can be limited to a certain number of concurrent executions across the entire scheduler
using either reschedule (skip when the limit is met) or queue (jobs are added to a queue to
wait for the limit to be available).
- **Note:** A scheduler limit and a job limit can both be enabled.
- **Distributed instances of gocron**: Multiple instances of gocron can be run.
- [**Elector**](https://pkg.go.dev/github.com/go-co-op/gocron/v2#WithDistributedElector):
An elector can be used to elect a single instance of gocron to run as the primary with the
other instances checking to see if a new leader needs to be elected.
- Implementations: [go-co-op electors](https://github.com/go-co-op?q=-elector&type=all&language=&sort=)
- [**Locker**](https://pkg.go.dev/github.com/go-co-op/gocron/v2#WithDistributedLocker):
A locker can be used to lock each run of a job to a single instance of gocron.
- Implementations: [go-co-op lockers](https://github.com/go-co-op?q=-lock&type=all&language=&sort=)
- **Events**: Job events can trigger actions.
- [**Listeners**](https://pkg.go.dev/github.com/go-co-op/gocron/v2#WithEventListeners):
Can be added to a job, with [event listeners](https://pkg.go.dev/github.com/go-co-op/gocron/v2#EventListener),
or all jobs across the
[scheduler](https://pkg.go.dev/github.com/go-co-op/gocron/v2#WithGlobalJobOptions)
to listen for job events and trigger actions.
- **Options**: Many job and scheduler options are available.
- [**Job options**](https://pkg.go.dev/github.com/go-co-op/gocron/v2#JobOption):
Job options can be set when creating a job using `NewJob`.
- [**Global job options**](https://pkg.go.dev/github.com/go-co-op/gocron/v2#WithGlobalJobOptions):
Global job options can be set when creating a scheduler using `NewScheduler`
and the `WithGlobalJobOptions` option.
- [**Scheduler options**](https://pkg.go.dev/github.com/go-co-op/gocron/v2#SchedulerOption):
Scheduler options can be set when creating a scheduler using `NewScheduler`.
- **Logging**: Logs can be enabled.
- [Logger](https://pkg.go.dev/github.com/go-co-op/gocron/v2#Logger):
The Logger interface can be implemented with your desired logging library.
The provided NewLogger uses the standard library's log package.
- **Testing**: The gocron library is set up to enable testing.
- Mocks are provided in [the mock package](mocks) using [gomock](https://github.com/uber-go/mock).
- Time can be mocked by passing in a [FakeClock](https://pkg.go.dev/github.com/jonboulle/clockwork#FakeClock)
to [WithClock](https://pkg.go.dev/github.com/go-co-op/gocron/v2#WithClock) -
see the [example on WithClock](https://pkg.go.dev/github.com/go-co-op/gocron/v2#example-WithClock).
