Functions

func DePunify

func DePunify(domain string) (string, error)

DePunify converts the given punycode string to its original unicode representation (lowercased). Noop if the domain is (already) not puny.

Returns an error if conversion fails.

func EmptyPageableResponse

func EmptyPageableResponse() *apimodel.PageableResponse

EmptyPageableResponse just returns an empty PageableResponse with no link header or items.

func ExtractNamestringParts

func ExtractNamestringParts(mention string) (username, host string, err error)

ExtractNamestringParts extracts the username test_user and the domain example.org from a string like @test_user@example.org.

If nothing is matched, it will return an error.

func ExtractWebfingerParts

func ExtractWebfingerParts(webfinger string) (username, host string, err error)

ExtractWebfingerParts returns username test_user and domain example.org from a string like acct:test_user@example.org, or acct:@test_user@example.org.

If nothing is extracted, it will return an error.

func FormatISO8601

func FormatISO8601(t time.Time) string

FormatISO8601 converts the given time to UTC and then formats it using the ISO8601 const, which the Mastodon API is able to understand.

func IsMentionOrHashtagBoundary

func IsMentionOrHashtagBoundary(r rune) bool

Decides where to break before or after a #hashtag or @mention

func IsPermittedInHashtag

func IsPermittedInHashtag(r rune) bool

func IsPlausiblyInHashtag

func IsPlausiblyInHashtag(r rune) bool

func PackagePageableResponse

func PackagePageableResponse(params PageableResponseParams) (*apimodel.PageableResponse, gtserror.WithCode)

PackagePageableResponse is a convenience function for returning a bunch of pageable items (notifications, statuses, etc), as well as a Link header to inform callers of where to find next/prev items.

func ParseISO8601

func ParseISO8601(in string) (time.Time, error)

ParseISO8601 parses the given time string according to the ISO8601 const.

func Punify

func Punify(domain string) (string, error)

Punify converts the given domain to lowercase then to punycode (for international domain names).

Returns the resulting domain or an error if the punycode conversion fails.

func ShortcodeDomain

func ShortcodeDomain(emoji *gtsmodel.Emoji) string

ShortcodeDomain returns the [shortcode]@[domain] for the given emoji.

func UniqueStrings

func UniqueStrings(s []string) []string

UniqueStrings returns a deduplicated version of a given string slice.

func UniqueURIs

func UniqueURIs(s []*url.URL) []*url.URL

UniqueURIs returns a deduplicated version of a given *url.URL slice.

Types

type PageableResponseParams

type PageableResponseParams struct {
	Items            []interface{} // Sorted slice of items (statuses, notifications, etc)
	Path             string        // path to use for next/prev queries in the link header
	NextMaxIDKey     string        // key to use for the next max id query param in the link header, defaults to 'max_id'
	NextMaxIDValue   string        // value to use for next max id
	PrevMinIDKey     string        // key to use for the prev min id query param in the link header, defaults to 'min_id'
	PrevMinIDValue   string        // value to use for prev min id
	Limit            int           // limit number of entries to return
	ExtraQueryParams []string      // any extra query parameters to provide in the link header, should be in the format 'example=value'
}

PageableResponseParams models the parameters to pass to PackagePageableResponse.

The given items will be provided in the paged response.

The other values are all used to create the Link header so that callers know which endpoint to query next and previously in order to do paging.
