Hi all, i'm using OSProcess to write something on the mac OS X terminal but when i execute : OSProcess thisOSProcess stdOut nextPutAll: 'Hello World'. nothing seems to happen ...
I'm using Squeak 3.8.18beta1U Mac OS X VM, sq3.9-7067dev07.01.1 image and OSProcess 4.3.3. I launch Squeak from the terminal with the open command.
When i launch the Squeak binary inside the Squeak application, the previous expression write the 'Hello World' string on the terminal.

If you did open "Squeak 3.8.18beta1U.app" that will not work, the open command forks off the process. If you look in your console.log you should confirm you see the 'Hello World'
If you want to launch the binary in a terminal session and keep control of the stdin/stdout you must do
./Squeak\ 3.8.18beta1U.app/Contents/MacOS/Squeak\ VM\ Opt
That likely will print these two messages
2007-07-26 03:13:54.252 Squeak VM Opt[7642] CFLog (0): CFMessagePort: bootstrap_register(): failed 1103 (0x44f), port = 0x2803, name'org.squeak.Squeak.ServiceProvider' See /usr/include/servers/bootstrap_defs.h for the error codes. 2007-07-26 03:13:54.256 Squeak VM Opt[7642] CFLog (99): CFMessagePortCreateLocal(): failed to name Mach port (org.squeak.Squeak.ServiceProvider)
And then your test gives.
Hello World
For the curious if you you do
./Squeak\ 3.8.18beta1U.app/Contents/MacOS/Squeak\ VM\ Opt -help
it will print
Usage: ./Squeak 3.8.18beta1U.app/Contents/MacOS/Squeak VM Opt [<option>...] [<imageName> [<argument>...]] ./Squeak 3.8.18beta1U.app/Contents/MacOS/Squeak VM Opt [<option>...] -- [<argument>...]
Common <option>s: -help print this help message, then exit -memory <size>[mk] use fixed heap size (added to image size) -pathenc <enc> set encoding for pathnames (default: macintosh) -headless run in headless (no window) mode (default: false)
Notes: <imageName> defaults to `Squeak.image'. If `-memory' is not specified then the heap will grow dynamically. <argument>s are ignored, but are processed by the Squeak image. The first <argument> normally names a Squeak `script' to execute. Precede <arguments> by `--' to use default image.
Unix users may feel warm and fuzzy then.....
