Hello Keith,
Hello Casmiro, great to see you using Rio. The latest version has moved away from using "Rio" in the code and is now (for better or worse) using classes called File/Directory. Rio doesnt use exceptions very much at all for various reasons. It is relatively easy to test for existence, and there are other utilities provided. In your case where you want a basic stream, "returns nil if the file does not exist" aStream := 'aGivenFileName' asFile reader. "returns nil if the file does not exist" data = 'aGivenFileName' asFile contents. "The reading block is ignored if the file does not exist" 'aGivenFileName' asFile reader: [ :str | aChar := str next ]. "an explicit checks for existence are available via" 'aGivenFileName' asFile ifFileDo: [ :f | f contents ]. 'aGivenFileName' asFile ifExistsDo: [ :f | f contents ]. 'aGivenFileName' asFile ifAbsentDo: [ :f | f touch ]. The latest Rio is available from Universes, be prepared to replace senders of asRio with asFile/asDirectory thanks for the feedback, knowing the above wold you rather have exceptions still? best regards Keith
