Right!
In the very latest Zn I added ZnCharacterReadStream and ZnCharacterWriteStream
but I did not yet integrate/use them. These add character decoding and encoding
to binary streams, here are some tests that show how to use them:
testSimpleUTF8WriteStream
| string bytes stream |
string := 'élève en Français'.
bytes := ZnUTF8Encoder new encodeString: string.
stream := (ZnCharacterWriteStream on: #[] writeStream).
stream nextPutAll: string.
self
assert: stream wrappedStream contents
equals: bytes
testSimpleUTF8ReadStream
| string bytes |
string := 'élève en Français'.
bytes := ZnUTF8Encoder new encodeString: string.
self
assert: (ZnCharacterReadStream on: bytes readStream) upToEnd
equals: string
I think these could be useful in other places (FS) as well and help in getting
rid of some old stuff.
Mind you, these are currently still only experiments.
