Types

type Alarm 

type Alarm struct {
	Trigger     string `json:"trigger"`
	Action      string `json:"action"`
	Description string `json:"description,omitempty"`
}

Alarm represents a VALARM component.

type Calendar 

type Calendar struct {
	Href           string   `json:"href"`
	DisplayName    string   `json:"display_name"`
	Color          string   `json:"color,omitempty"`
	Description    string   `json:"description,omitempty"`
	ComponentTypes []string `json:"component_types,omitempty"`
}

Calendar represents a CalDAV calendar collection.

type Client 

type Client struct {
	// contains filtered or unexported fields
}

Client is a CalDAV HTTP client that supports PROPFIND, REPORT, PUT, DELETE, and MKCALENDAR operations.

func NewClient 

func NewClient(cfg *Config) *Client

NewClient creates a CalDAV client from the given configuration.

func (*Client) DeleteEvent 

func (c *Client) DeleteEvent(eventHref, etag string) error

DeleteEvent removes a VEVENT by href.

func (*Client) DeleteTask 

func (c *Client) DeleteTask(taskHref, etag string) error

DeleteTask removes a VTODO by href.

func (*Client) FindEventByUID 

func (c *Client) FindEventByUID(uid string) (*EventWithMeta, string, error)

FindEventByUID searches all calendars for an event with the given UID. Returns the event with metadata and the calendar href it was found in.

func (*Client) FindTaskByUID 

func (c *Client) FindTaskByUID(uid string) (*TaskWithMeta, string, error)

FindTaskByUID searches all calendars for a task with the given UID. Returns the task with metadata and the calendar href it was found in.

func (*Client) GetEvent 

func (c *Client) GetEvent(eventHref string) (*EventWithMeta, error)

GetEvent fetches a single VEVENT by its href.

func (*Client) GetTask 

func (c *Client) GetTask(taskHref string) (*TaskWithMeta, error)

GetTask fetches a single VTODO by its href.

func (*Client) ListCalendars 

func (c *Client) ListCalendars() ([]Calendar, error)

ListCalendars performs a PROPFIND to discover all calendar collections.

func (*Client) ListEvents 

func (c *Client) ListEvents(calendarHref string) (*EventListResult, error)

ListEvents performs a REPORT calendar-query to list all VEVENTs in a calendar. Parse errors for individual events are collected in EventListResult.ParseErrors rather than causing the entire listing to fail.

func (*Client) ListTasks 

func (c *Client) ListTasks(calendarHref string) (*TaskListResult, error)

ListTasks performs a REPORT calendar-query to list all VTODOs in a calendar. Parse errors for individual tasks are collected in TaskListResult.ParseErrors rather than causing the entire listing to fail.

All tasks are returned regardless of STATUS. Server-side filtering via prop-filter is deferred until incremental sync is implemented — the haustoria's status-tags mapping requires completed tasks during checkin. https://github.com/amarbel-llc/dodder/issues/87

func (*Client) MkCalendar 

func (c *Client) MkCalendar(href, displayName, description string) error

MkCalendar creates a new calendar collection via MKCALENDAR.

	Password string
}

Config holds CalDAV connection parameters read from environment variables.

func ConfigFromEnv 

func ConfigFromEnv() (*Config, error)

ConfigFromEnv reads CALDAV_URL, CALDAV_USERNAME, and CALDAV_PASSWORD from the environment. Returns an error if any required variable is missing.

Task is the structured representation of a VTODO component, covering all fields that tasks.org uses.

func ParseVTODO 

func ParseVTODO(raw string) (*Task, error)

ParseVTODO parses a raw iCalendar string and extracts the first VTODO as a Task. For recurring tasks (RRULE), a single .ics resource may contain multiple VTODO components: a master plus overrides with RECURRENCE-ID. This function returns only the first (master) VTODO. Override components are not extracted because dodder maps each CalDAV resource to one zettel — the recurring pattern is the conceptual unit, not individual instances.

type TaskMetadata struct {
	UID               string   `json:"uid"`
	Summary           string   `json:"summary"`
