Re: [Pharo-users] Running headless on Windows

[Torsten Bergmann]

Yes:  https://github.com/OpenSmalltalk/opensmalltalk-vm/pull/184

Seems fixed for openSmalltalk VM source code.

But I can not try as unfortunately the "pharo-win-latest.zip" (32 bit) is still 
back from 
November 2017 (see http://files.pharo.org/get-files/70/)

So I guess some Esteban magic is required first to receive a new windows VM 
build 
for Pharo.

do you know if there is bug entry for this problem?

If you want to run Pharo as a service, I have found nssm to be working well.

Hi Andrei,

can you try this:

Open Pharo normal (no headless option).
Change the window size to "not-maximized" (eve if it is actually not
maximized, maximize it ones and change it back to "not-maximized")
Save and quit the image.

After that, a call like

pharo --headless pharo.image eval "DateAndTime now"

will write the output to the stdout file, without opening a window.

Pierce, I tried all of those "no display" options, the result is the same

I know OP is talking about Windows...  I've been running server applications on
Linux without X11 with -vm-display-null and in-image RFBServer for access to
Pharo over VNC. This works very well for me.

I believe "real" headless means GUI is not run at all and therefore does not
consume CPU cycles, which is very welcome. Meanwhile, maybe -vm-display-null
works on Windows for scripting purposes?

Denis, I tried both. Running pharoconsole makes no difference. Same result
as running Pharo.exe

[Pharo-users] Running headless on Windows

[Andrei Stebakov]

When I run Pharo 6.1 with -- headless option on Windows, it executes the
eval command as expected but during the execution (which lasts 4 sec) it
opens the Pharo GUI.
Is it expected? I thought headless means that the whole execution would
happen in the background
