I think that mixing the code for text and binary modes in single class is a source of errors and confusion. The code: stream := (working / 'foo.txt') writeStream. should be something like: stream := (working / 'foo.txt') writeStream textStream. where textStream should answer the wrapper stream around the original stream, something like: textStream ^ UnicodeTextWriteStream on: self then when you do: stream nextPutAll: 'abc' the wrapper stream takes care about converting input string into bytearray and then passing it further to basic stream. Of course there could be an optimization, if input string are bytestring etc , but model should be separated. > Lukas > > On 13 September 2011 16:36, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> wrote: >> or strings and widestrings. >> >> Stef >> On Sep 13, 2011, at 4:11 PM, Alexandre Bergel wrote: >> >>> Looks like there is a confusion between binary and text stream >>> >>> Alexandre >>> >>> On 13 Sep 2011, at 11:09, StÃ©phane Ducasse wrote: >>> >>>> | working stream | >>>> working := FSFilesystem disk workingDirectory. >>>> stream := (working / 'foo.txt') writeStream. >>>> stream nextPutAll: 'Hello World'. >>>> stream close. >>>> stream := (working / 'foo.txt') readStream. >>>> stream contents. >>>> Â Â Â returns >>>> Â Â Â #[72 101 108 108 111 32 87 111 114 108 100] >>>> >>>> instead of 'Hello World' >>>> >>>> Does anybody have a fix..? >>>> >>>> Stef ( editing FS chapter). >>>> >>> >>> -- >>> _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: >>> Alexandre Bergel Â http://www.bergel.eu >>> ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;. >>> >>> >>> >>> >>> >>> >> >> >> > > > > -- > Lukas Renggli > www.lukas-renggli.ch > > -- Best regards, Igor Stasenko AKA sig.

Re: [Pharo-project] FS writestream

by Camillo Bruni

Concerning the encoding problem I would say so tooâ¦ But there's another "problem" with FS file streams, they are correctly programmed and have a 1 based index. Whereas existing FileStreams are 0 based (no clue why that..) As an example I remember that we could not dump MCZ files directly to FSFilestreams since the zip compressor relies on 0 based indexingâ¦ I guess we need a big refactoring for this to work completely.. cami On 2011-09-13, at 16:41, Lukas Renggli wrote: > Then you also need to specify an encoding.

Then you also need to specify an encoding. Otherwise it does not make sense for a FSReadStream to return a String. Strictly speaking the FSWriteStream shouldn't accept a String as input either.

Re: [Pharo-project] Developing on virtualized Android

by Dimitry Golubovsky

Torsten, No, I started on a real ARM device. ARM emulator was way too slow on my 2 GHz Athlon64x2. I considered it cheaper to buy an actual device (cost me $160, and I needed one anyway) than to buy a faster PC ;). That was in January 2011; now I think these devices got even cheaper. I never really considered x86 Android. Thanks.

[Pharo-project] FS writestream

by StÃ©phane Ducasse

| working stream | working := FSFilesystem disk workingDirectory. stream := (working / 'foo.txt') writeStream. stream nextPutAll: 'Hello World'. stream close. stream := (working / 'foo.txt') readStream. stream contents. returns #[72 101 108 108 111 32 87 111 114 108 100] instead of 'Hello World' Does anybody have a fix..?
