Introduction into OSProcess
Locked
 
|
Hello,
I am trying to run a simple shell command using OSProcess: ExternalWindowsOSProcess command: 'taskmgr.exe' I'm afraid it "does not work", so after evaluating this expression, no window opens and also no icon appears in the systray. If I open cmd.exe and type taskmgr.exe there, taskmgr opens. However, the following works as expected: ExternalWindowsOSProcess command: 'notepad.exe' Using absolute paths did not change the behavior. I installed the latest OSProcess version via SqueakMap. Is this a bug, or is it me? Thanks in advance!

Hi, I am new in here and to Squeak in general. To me OSProcess works in MacOS and FreeBSD (Linux emulation). I don't have a Windows machine to try unfortunately. This is a list of working examples (in my operating systems), maybe try to run something similar in Windows. I guess the equivalent of "ls" is "dir". ------------------------------------------------- "in this case we want to take the output from an external program" p := PipeableOSProcess command: 'ls -la'. commandOutput := p output. commandOutput. "in this case you don't take the output, just run a program." p := OSProcess command: 'ls -la'. "In FreeBSD (Linux emulation) it works, open Emacs in a GUI." p := OSProcess command: 'emacs'. --------------------------------------------------- bye Nicola On 8/3/19 7:50 PM, Christoph Thiede

Christoph, You are more fortunate than I am. I tried it on my Win 7 box and it caused a crash. There is a way to send output to stdout and stderr . Try adding that to your command and see what you get.

Hi John,
[(OSProcess command: 'notepad.exe 2>&1') value] passes '>2&1' as an argument to notepad.exe. If I use PipeableOSProces instead, there is only shown an empty cmd window, no matter what the command is.
@Nicola: Strange, running your first example made my Squeak cursor flickering until I interrupted the command ...

Hi Dave,
thank you for the hint, but the dependency chain of ProcessWrapper seems very long (ProcessWrapperPlugin, SmartSyntaxInterpreterPlugin, VMMaker, KlattResonatorIndices, FFI, ...). Can I get SmartSyntaxInterpreterPlugin anywhere separately?

I can't check this myself right now, but if you go to the
http://www.squeaksource.com page and navigate to the ProcessWrapper project, the overview page says that you can download a copy of the plugin by evaluating "ProcessWrapper downloadPlugin". If that works, then you can copy the plugin dll to the folder for your VM (wherever the other plugin dll's are located), and hopefully it will just work. I am guessing that the download will be for a 32 bit Windows VM.

Double check: ------- p := PipeableOSProcess command: 'ls -la'. p output. ------- 1] In MacOS 10.14.5, confirmed to work. 2] In FreeBSD 12 (Linux emulation 64bit) , confirmed to work Can't tell you much more unfortunately. bye Nicola
