Overview

Package filedef contains general implementation of known common file types retrieved from Garmin or its affiliates website and a listener building block convert decoded FIT file into the desired common file type as soon as the message is decoded.

You may find that the common file types declared here are not sufficient for your need, but don't worry, you can always create your own common file types that suit your need more; whether creating a fresh one or embedding the existing; and still be able to use listener building block as long as it satisfy the File interface.

Functions

func SortMessagesByTimestamp added in v0.2.0 

func SortMessagesByTimestamp(messages []proto.Message)

SortMessagesByTimestamp sorts messages by timestamp. The following rules will apply:

  • Any message without timestamp field will be placed to the beginning of the slice to enable these messages to be retrieved early such as UserProfile.
  • Any message with invalid timestamp will be places at the end of the slices.

Special Case:

All timestamp fields should have num 253, except:

  • Course Point's Timestamp num: 1
  • Set's Timestamp num: 254

We will sort these timestamps accordingly since the messages' order matters.

For details, see github.com/muktihari/fit/proto.FieldNumTimestamp doc.

Types

type Activity 

type Activity struct {
	FileId mesgdef.FileId // required fields: type, manufacturer, product, serial_number, time_created

	// Developer Data Lookup
	DeveloperDataIds  []*mesgdef.DeveloperDataId
	FieldDescriptions []*mesgdef.FieldDescription

	// Required Messages
	Activity *mesgdef.Activity  // required fields: timestamp, num_sessions, type, event, event_type
	Sessions []*mesgdef.Session // required fields: timestamp, start_time, total_elapsed_time, sport, event, event_type
	Laps     []*mesgdef.Lap     // required fields: timestamp, event, event_type
	Records  []*mesgdef.Record  // required fields: timestamp

	// Optional Messages
	UserProfile  *mesgdef.UserProfile
	DeviceInfos  []*mesgdef.DeviceInfo // required fields: timestamp
	Events       []*mesgdef.Event
	Lengths      []*mesgdef.Length // required fields: timestamp, event, event_type
	SegmentLaps  []*mesgdef.SegmentLap
	ZonesTargets []*mesgdef.ZonesTarget
	Workouts     []*mesgdef.Workout
	WorkoutSteps []*mesgdef.WorkoutStep
	HRs          []*mesgdef.Hr
	HRVs         []*mesgdef.Hrv // required fields: time

	// Messages not related to Activity
	UnrelatedMessages []proto.Message
}

Activity is a common file type that most wearable device or cycling computer uses to record activities.

Please note since we group the same mesgdef types in slices, we lose the arrival order of the messages. But for messages that have timestamp, we can reconstruct the messages by timestamp order.
