 TabularResources testExcelSheet

from this project gives me a binary representation in a literal array of an Excel file.

Question

How do I write this to the disk to see which kind of file it is?

Answer

(by Esteban, edited)

./TabularATest1.xlsx' asFileReference writeStreamDo: [ :stream | stream binary; nextPutAll: self testExcelSheet ]

Easiest way to do that is something like this: 

'./file.bin' asFileReference writeStreamDo: [ :stream | 
    stream 
        binary; 
        nextPutAll: #[1 2 3 4 5 6 7 8 9 0] ]

So the trick is just telling to the stream "be a binary file" :)

  • Note that there is a compatibility issue at the moment which requires you to use #binaryReadStream et. al if you want to read binary data.

  • @MaxLeske -- could you please elaborate a bit? I added a code snippet based on EstebanLM's answer and it worked.

    For clarification: I was talking about reading binary data. The way that read streams are constructed at the moment does not allow switching from ascii to binary mode. Instead, you should use #binaryReadStream et. al to get a binary readstream. If you don't do that, you may experience some weird things happening to your data. The plan is to get rid of those extra messages ASAP, but for the moment they are there.
