Functions

func DecodeUserLocalpart 

func DecodeUserLocalpart(str string) (string, error)

DecodeUserLocalpart decodes the given string back into the original input string. Returns an error if the given string is not a valid user ID localpart encoding. See http://matrix.org/docs/spec/intro.html#mapping-from-other-character-sets

This decodes quoted-printable bytes back into UTF8, and unescapes casing. For example: 

_alph=40_bet=5f50up  =>  Alph@Bet_50up

Returns an error if the input string contains characters outside the range "a-z0-9._=-", has an invalid quote-printable byte (e.g. not hex), or has an invalid _ escaped byte (e.g. "_5").

func EncodeUserLocalpart 

func EncodeUserLocalpart(str string) string

EncodeUserLocalpart encodes the given string into Matrix-compliant user ID localpart form. See http://matrix.org/docs/spec/intro.html#mapping-from-other-character-sets

This returns a string with only the characters "a-z0-9._=-". The uppercase range A-Z are encoded using leading underscores ("_"). Characters outside the aforementioned ranges (including literal underscores ("_") and equals ("=")) are encoded as UTF8 code points (NOT NCRs) and converted to lower-case hex with a leading "=". For example: 

Alph@Bet_50up  => _alph=40_bet=5f50up

func ExtractUserLocalpart 

func ExtractUserLocalpart(userID string) (string, error)

ExtractUserLocalpart extracts the localpart portion of a user ID. See http://matrix.org/docs/spec/intro.html#user-identifiers

func TrimReplyFallbackHTML 

func TrimReplyFallbackHTML(html string) string

func TrimReplyFallbackText 

func TrimReplyFallbackText(text string) string

func (*Client) Sync 

func (cli *Client) Sync() error

Sync starts syncing with the provided Homeserver. If Sync() is called twice then the first sync will be stopped and the error will be nil.

This function will block until a fatal /sync error occurs, so it should almost always be started as a new goroutine. Fatal sync errors can be caused by:

  • The failure to create a filter.
  • Client.Syncer.OnFailedSync returning an error in response to a failed sync.
  • Client.Syncer.ProcessResponse returning an error.

If you wish to continue retrying in spite of these fatal errors, call Sync() again.
