Fast (and opinionated) ICAL parser in Golang.

Gocal takes an io.Reader and produces an array of Events from it.

package main

func main() {
  f, _ := os.Open("/tmp/mycalendar.ics")
  defer f.Close()

  c := gocal.NewParser(f)
  c.Parse()

  for _, e := range c.Events {
    fmt.Printf("%s on %s by %s", e.Summary, e.Start, e.Organizer.Cn)
  }
}

I do not pretend this abides by RFC 5545, this only covers parts I needed to be parsed for my own personal use. Among other, most propery parameters are not handled by the library, and, for now, only the following properties are parsed:

• UID
• SUMMARY / DESCRIPTION
• DTSTART / DTEND (day-long, local, UTC and TZIDd)
• DTSTAMP / CREATED / LAST-MODIFIED
• LOCATION
• STATUS
• ORGANIZER (CN; DIR and value)
• ATTENDEEs (CN, DIR, PARTSTAT and value)
• ATTACH (FILENAME, ENCODING, VALUE, FMTTYPE and value)
• CATEGORIES
• GEO

And I do not (for now) try and parse RRULEs, so recurring events will show as a single event.

Also, we ignore whatever's not a VEVENT.
