Thanks for the code Eliot. Can you give me a hint about proper usage.<br>

<br>
I also found StandardFileStream<br>
class>>#standardIOStreamNamed:forWrite: but it has undeclared<br>

understand what arguments I should pass...<br>

That class instance variable is missing, but the code still works. Try this:<br>
<br>
CrLfFileStream stdout nextPutAll: 'Hello World!'.<br></blockquote><div><br></div><div>That's right. This is missing:</div><div><br></div><div><div>StandardFileStream class</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>instanceVariableNames: 'stdioFiles'</div>

Hi Chris,<br>
<br>
I have code for this, but right now I need to crack some crabs, so I<br>
don't have time to verify this code in 4.1 :) Use at your own risk ;)<br>
The<br>
most important thing is the StandardFileStream>>stdioHandles primitive<br>
for<br>
accessing the streams. N.B. some work needs to be done on the win32<br>
FilePlugin support code before this will work on Windows.<br>
</blockquote>
<br>
All three streams seem to be working on Windows Vista with the latest<br>
CogVM.<br>
This seems to be a really cool feature, though I think CrLfFileStream<br>
should be deprecated, so MultiByteFileStream support would be better IMO.<br>
</blockquote>
<br>
The streams work if directed to files. But they will /not/ work if<br>
directed to input or output in a console window. I should have been<br>
clearer, sorry. The work needed is in<br>
platforms/win32/plugins/FilePlugin/sqWin32FilePrims.c where if input and/or<br>
output is the console we need to use ReadConsole & WriteConsole in place of<br>
ReadFile & WriteFile.<br>
</blockquote>
<br>
Hmmm. Turns out I was confused about this. One doesn't need ReadConsole &<br>
WriteConsole; ReadFile & WriteFile should do just fine. But the Cog code<br>
doesnt work in either an MS-DOS console window or a cygwin console window.<br>
If anyone's familiar with this area of Windows please feel free to take a<br>
look...<br>
TIA<br>

I am developing a simple "CommandLineProcessor" facade for easily<br>
transferring command-line arguments simply as block-arguments, so you<br>
can write smalltalk scripts in vi:<br>
<br>
CommandLineProcessor do: [ : arg1 : arg2 : arg3 | "args come in as<br>
Strings" ... ]<br>
<br>
and also for directing Notifications and Warnings messages to stdOut,<br>
and Errors to stdErr. It relies on OSProcess to write to stdOut and<br>
stdErr for this. However, ever since switching to Cog, writing to<br>
these streams does not seem to redirect out to Linux..<br>
<br>
I don't know whether writing to these streams makes me<br>
Linux-dependent, but it really is nice to be able to write Linux<br>
scripts that employ Squeak in the back-end, but operate normally like<br>
other shell programs in the terminal window and with redirecting<br>
output, etc.<br>
