**Go library for working with recurrence rules for calendar dates.**
Inspired by the amazing [rrule.js](https://github.com/jkbrzt/rrule).
* * * * *
### Quick Start
#### Installation
The only requirement is the [Go Programming Language](https://golang.org/dl/), at least 1.8
```bash
$ go get github.com/JulienBreux/rrule
```
#### Overview
##### RRule
```go
// Create a rule
rule := rrule.RRule{
freq: rrule.WEEKLY,
interval: 5,
byweekday: [rrule.MO, rrule.FR],
dtstart: time.Date(2017, time.January, 1, 10, 30, 0, 0, time.UTC),
until: time.Date(2017, time.December, 31, 10, 30, 0, 0, time.UTC),
}
// Get all occurrence dates (Date instances)
rule.All()
// Get a slice of occurrence dates (Date instances)
rule.Between(
time.Date(2017, time.August, 1, 10, 30, 0, 0, time.UTC),
time.Date(2017, time.September, 1, 10, 30, 0, 0, time.UTC),
)
// Get an iCalendar RRULE string representation:
// The output can be used with RRule.FromString("...").
rule.ToString()
```
##### RRuleSet
```go
// Create a rule set
set := rrule.RRuleSet{}
// Add a rule to set
set.RRule(
rrule.RRule{
freq: rrule.MONTHLY,
count: 2,
dtstart: time.Date(2017, time.January, 1, 10, 30, 0, 0, time.UTC),
}
)
// Add an exclusion rule to set
set.ExRule(
rrule.RRule{
freq: rrule.MONTHLY,
count: 2,
dtstart: time.Date(2017, time.February, 1, 10, 30, 0, 0, time.UTC),
}
)
// Add a date to set
set.RDate(time.Date(2017, time.June, 1, 10, 30, 0, 0, time.UTC))
// Add an another date to set
set.RDate(time.Date(2017, time.June, 2, 10, 30, 0, 0, time.UTC))
// Add an exclusion date to set
set.ExDate(time.Date(2017, time.May, 1, 10, 30, 0, 0, time.UTC))
// Get all occurrence dates (Date instances)
set.All()
// Get a slice of occurrence dates (Date instances)
set.Between(
time.Date(2017, time.February, 1, 10, 30, 0, 0, time.UTC),
time.Date(2017, time.June, 2, 10, 30, 0, 0, time.UTC),
)
// Array of strings (e.g. ["RRULE:...", "RDATE:...", "EXRULE:...", "EXDATE:..."])
set.ValueOf()
// To string (array stringified) (e.g. "["RRULE:...", "RDATE:...", "EXRULE:...", "EXDATE:..."]")
set.ToString()
```
##### RRule parser
```go
// Parse a RRule string, to a RRule instance
rrule.StrToRule("RRULE:FREQ=MONTHLY;COUNT=5;DTSTART=20170201T023000Z")
// Parse a RRule string, to a RRuleSet instance
rrule.StrToRuleSet("RRULE:FREQ=MONTHLY;COUNT=5;DTSTART=20170201T023000Z")
// Parse a RRuleSet string, to a RRuleSet instance
rrule.StrToRuleSet(
"RRULE:FREQ=MONTHLY;COUNT=5;DTSTART=20170201T023000Z\n"+
"RDATE:20170701T023000Z,20170702T023000Z\n"+
"EXRULE:FREQ=MONTHLY;COUNT=2;DTSTART=20170301T023000Z\n"+
"EXDATE:20170601T023000Z")
```
