Indeed. This is what I think should work. And yes, I don't think the
'JAVA_HOME'  is needed. At least for this command.

Alex, let us know if Peter code worked.

Re: [Pharo-users] Using OSSubProcess to invoke Java

[Peter Uhnák]

#runAndWaitOnExitDo: takes a cull-ed three-arg block with the process,
stdout, and stderr; that way you can process stdout and stderr
independently.

Try this

OSSUnixSubprocess new
  command: '/usr/bin/java';
arguments: #('-version');
redirectStderr;
runAndWaitOnExitDo: [ :process :out :err |
err inspect
].

Re: [Pharo-users] Using OSSubProcess to invoke Java

[Alexandre Bergel]

Hi Mark,

This is what I thought. But it does not seem to work. I tried:

OSSUnixSubprocess new
  command: '/usr/bin/java';
  arguments: #('-version');
redirectStderr;
 
  runAndWaitOnExitDo: [ :process :outString  |
  outString inspect
  ].

Or is it the redirectStderr that does not work properly?

Cheers,
Alexandre

Re: [Pharo-users] Symbolic links in Pharo

[Peter Uhnák]

You can use FFI; just create an object with a method…

MyObject>>system: command
"Perform OS system() call."

^ self ffiCall: #(int system #(char * command)) module: LibC


And then you can do something like

MyObject new system: 'ln -s /tmp/source /tmp/target'

[Pharo-users] Dragging window only from its title

[Hilaire]

Hi,

Is it possible to drag a SystemWindow/StandardWindow ONLY from its
title, on the top?

Currently, the behaviour is: any area of the windows where there is no
widget behaves as a select point of the whole window.

For some young -- and older -- users of Dr.Geo it can be confusing.

I look at it but did not find obvious way to do it but hacking
#aboutToBeGrabbed: method.

Did I miss something?

Thanks

With the introduction of the session manager, error handling during startup 
actions was revisited.
You can check StartupUIManager>>#handleError:log: for errors coming before 
Morphic is initialized.
Once Morphic is initialized, you get a default UI manager (MorphicUIManager if 
in UI mode). It is managed by UIManagerSessionHandler class.

If your startup code is executed with StartupUIManager, it will add a deferred 
startup action to execute the inform, else it fallback to MorphicUIManager 
inform.
It should do the behavior you expect.

Could you give me more info (the stacktrace would be useful)? 

Cheers,
Christophe
