where is appendStream?

Hello,
I use in Pharo 2.0 the class FileSystem to write in a text file(csv format). I find only two options writeStream and readStream. I would not like each time to overwrite the contents of my file and I do not find the option appendStream. How can I do?

working := FileSystem disk workingDirectory.
stream := (working / 'test.csv') writeStream

stream nextPutAll: 'something'.
stream nextPutAll: ';' .
stream nextPutAll: 'other'.

stream close.

Hayatou,

Open a WriteStream and call #setToEnd before writing.

I'm sure these changes in the API are documented somewhere extensively,
however I cannot find it. Do you have any pointers/links?

TIA,

I don't understand the question. AFAIK, there has been anything else. This is the way it is. I find it quite logical.

Not that the Stream hierarchy makes perfect sense in all cases, but that is another story ;-)

In reply to this post by hayatou

you can use

fileReference writeStream setToEnd

instead of just writeStream, that should be the same behavior as appendStream...
