Yes, i have to create a new file fith the modifications. All what i've done for now is to copy the content of the original file in a stream and paste it in the new file, without any mofication Le 16 mai 2015 10:09, "Sergio Fedi" <sergio.fedi@gmail.com> a écrit :

Do you have to modify the file? Create a new file with the modifications? Or get the file in memory but modified?

Hi,

You can do it by using on a subclass of WriteStream "peek" and "nextPut:" methods. Or you can transform the stream into a Collection by using "contents" and do almost everything you want.

Cheers, Vincent

Maybe you should open a stream reading the original file the open a writing stream for the copy file And reading from one, writing on the other, replacing what you need in the intermediate collection of bytes/characters ​

To replace all X's in input.txt with Y's in output.txt, you can do: 'input.txt' asFileReference readStreamDo: [ :in | 'output.txt' asFileReference writeStreamDo: [ :out | [ in atEnd ] whileFalse: [ | ch | (ch := in read) = $X ifTrue: [ out nextPut: $Y ] ifFalse: [ out nextPut: ch ] ] ] ].
