base16 cljs

base16->bytes cljs

(base16->bytes)

Transcode base16 characters to bytes.

base64 cljs

base64->bytes cljs

(base64->bytes web-safe?)

Transcode base64 characters to bytes. Takes groups of four 6-bit inputs and converts them to three 8-bit outputs.

base64-decode-byte clj/s macro

(base64-decode-byte n b0 b1 b2 b3)

Decodes an 8-bit byte from 6-bit base64 bytes. n is one of 0-2 indicating position in 24-bit group.

base64-encode-byte clj/s macro

(base64-encode-byte n b0 b1 b2)

Encodes a 6-bit byte from three 8-bit base64 bytes. n is one of 0-3 indicating position in 24-bit group.

base64url cljs

bytes->base16 cljs

(bytes->base16)

Trancode bytes to base16 characters.

bytes->base64 cljs

(bytes->base64 web-safe?)

Transcode from bytes to base64 using the specified alphabet (standard or websafe). Takes groups of three 8-bit inputs and converts them to four 6-bit characters.

decode-data cljs

(decode-data data codec)

Decode a byte array from a string using the given encoding.

decode-edn cljs

(decode-edn in codec)

Read EDN data from a UTF-8 string encoded with the given codec.

decode-string cljs

(decode-string in codec)

Decode a string from the given data string using the given codec, assuming UTF-8 bytes.

decoder cljs

(decoder codec)

Return a decoding transcoder for the given string encoding.

encode-data cljs

(encode-data bytes codec)

Encode a byte array to a string using the given codec.

encode-edn cljs

(encode-edn in codec)

Render the given input as EDN then encode as UTF-8 bytes using the given codec.

encode-string cljs

(encode-string in codec)

Encode a string to UTF-8 bytes using the given codec.

encoder cljs

(encoder codec)

Return an encoding transcoder for the given string encoding.

from-char-code cljs

(from-char-code c)

Given a numerical unicode code point, returns a javascript UTF-16 string.

into-bytes cljs

(into-bytes xf inputs)

Returns an array constructed from applying the given transducing stack to the input sequence.

into-string cljs

(into-string xf inputs)

Returns a string constructed from applying the given transducing stack to the input sequence.

to-char-code cljs

(to-char-code string)

(to-char-code string index)

Given a javascript UTF-16 string and an index, return a unicode code point.

unicode->utf16 cljs

(unicode->utf16)

Transcoder from unicode characters to UTF-16 characters.

unicode->utf8 cljs

(unicode->utf8)

Transcode from unicode code points to UTF-8 bytes.

unicode-sanitise cljs

(unicode-sanitise char)

(unicode-sanitise size char)

Sanitise unicode code points by replacing overlong and non-character code points with the unicode replacement character (0xfffd). Optionally takes a UTF-8 codepoint size to check for overlong encodings.

utf16->unicode cljs

(utf16->unicode)

Transcode from javascript utf-16 characters to unicode code points.

utf8->unicode cljs

(utf8->unicode)

Transcode from utf-8 bytes to unicode code points.

utf8-continuation clj/s macro

(utf8-continuation char)

(utf8-continuation n char)

Returns a UTF-8 continuation byte for the given code point data (2 bit header plus 6 bits of data).

utf8-header clj/s macro

(utf8-header size char)

Returns a UTF-8 header byte for a given code point (length prefix plus data bits).
