Examples

Makes a test string, estimated 38 bytes long by counting Japanese characters as 2 bytes.

CL-USER> (defvar *test-string* "abcde あいうえお アイウエオ 阿伊宇江於")
*TEST-STRING*

Let's compress it. The result is only 30 bytes long.

CL-USER> (cl-scsu:encode-from-string *test-string*)
#(97 98 99 100 101 32 21 130 132 134 136 138 32 226 228 230 232 234 32
  15 150 63 79 10 91 135 108 95 101 188) ; compressin result
30                                       ; number of result bytes
23                                       ; number of read characters
#<CL-SCSU:SCSU-STATE @ #x10002ed37c2>    ; scsu state object

To restore the original string, decompress the bytes.

CL-USER> (cl-scsu:decode-to-string *)
"abcde あいうえお アイウエオ 阿伊宇江於" ; decompression result
23                                       ; number of result characters
30                                       ; number of read bytes
#<CL-SCSU:SCSU-STATE @ #x10002f469f2>    ; scsu state object

6.1.1 Functions

Function: decode-to-string BYTES &key START1 END1 STRING START2 END2 STATE &aux STRING-FILL-POINTER-AT-FIRST

This function decompresses BYTES compressed by the SCSU and returns the result as a string. Returned values are following:

1. The result string decompressed by SCSU.
2. The position of the next of the last character written to the result string.
3. The position of the next of the last byte read from BYTES.
4. ‘scsu-state’ object.

Arguments are:

- BYTES

A byte sequence compressed by SCSU.

- START1, END1

Specifies the range of BYTES argument should be used.
Initial value is 0 and the length of BYTES respectively.

- STRING

Specifies an output storage filled by the decompression result.
This specified string is returned by ‘decode-to-string’.
If not specified, a new string is allocated and returned.

- START2, END2

Specifies the range of STRING argument used.
Initial value is 0 and the length of STRING respectively.
If STRING is not specified, these arguments are ignored.

- STATE

If specifies a ‘scsu-state’ object returned by previous ‘decode-to-string’ calls,
the shift state included the object is used.
If not specified, the initial state [http://unicode.org/reports/tr6/#Initial_State] is used.

If not specified, a new byte sequence is allocated and returned.

- START2, END2

Specifies the range of BYTES argument used.
Initial value is 0 and the length of BYTES respectively.
If BYTES is not specified, these arguments are ignored.

- INITIAL-PRIORITY

Specifies how to determine the priority of the initial dynamic window [http://unicode.org/reports/tr6/#Initial_Window] of SCSU as following:

- ‘:lookahead’ (default) :: Determines by lookaheading STRING argument.
- ‘:fixed’ :: Don’t change dynamic window.
- ‘:random’ :: determines randomly.
- an interger array :: Uses the array as a priority. Bigger is prior.

- STATE

If specifies a ‘scsu-state’ object returned by previous ‘encode-from-string’ calls,
the shift state included the object is used.
If not specified, the initial state [http://unicode.org/reports/tr6/#Initial_State] is used.
