Running headless on Windows
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
Hi. I think there is separate PharoConsole.exe for headless on Windows 2017-12-27 16:39 GMT+01:00 Andrei Stebakov <lispercat@gmail.com>:

I think that currently Pharo does not have a "real" headless. But I heard there was work on that part for Pharo 7. -- Cyril Ferlicot https://ferlicot.fr http://www.synectique.eu 2 rue Jacques Prévert 01, 59650 Villeneuve d'ascq France

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? Pierce
Pierce, I tried all of those "no display" options, the result is the same On Dec 28, 2017 8:37 PM, "Pierce Ng" <pierce@samadhiweb.com> wrote:

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.
If you want to run Pharo as a service, I have found nssm to be working well. https://nssm.cc Phil On Dec 29, 2017 09:25, "Nicolai Hess" <nicolaihess@gmail.com> wrote:

Hi, (cross posting vm-dev) nssm is nice - but requires additional tools. Since the days of Squeak the windows VM had the -service "ServiceName" option and one was able to run Squeak as a windows service out of the box. See http://wiki.squeak.org/squeak/105 for details. This option allows to register/deregister with the windows service manager and run a headless image. I run a Squeak Wiki (Swiki/Comanche) since years with this and it is very nice and stable. Unfortunately this is broken in recent Pharo VMs and so far Esteban or others did not have the time to look into this issue. Would be really nice if this option could be recovered in 2018. So one could easily deploy and run Seaside or Teapot/Tealight or Zinc/WebClient based web services on Windows. If we want to deploy Smalltalk based web applications or services on Windows we should support that. It will keep Windows administrators happy and we would integrate with the whole ecosystem (for instance you can start/stop a service using Windows scripting for doing backups, etc.) right out of the box.

I am using nssm because the service option is broken. The code seems to still be in the image but disabled (there are quite a few things like that actually). Phil On Fri, Dec 29, 2017 at 11:59 AM, Torsten Bergmann <astares@gmx.de> wrote:

Nicolai, the maximize/non-maximize trick worked! Thanks! I wonder if it's an easy fix to put in Pharo. On Fri, Dec 29, 2017 at 6:22 AM, phil@highoctane.be <phil@highoctane.be> wrote:

Maybe a problem on the image and the vm side. Even in headless mode, starting pharo creates a window. Even if it is hidden, it has some size. Quit and Saving an image will write the current width/height into the image file. Starting the vm will create a window and set the size of the window to the last size. The window is always created in normal (not-maximized) mode and the available size is a little bit smaller than for a maximized window. Now, the image checks for a change of the size of the current DisplayScreen instance and the actual screen size. If this is different (as in this case) a new DisplayScreen is initialized which will call a full screen update (ioForceDisplayUpdate). And this method will show a hidden (headless) image.

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
I think that currently Pharo does not have a "real" headless. But I heard there was work on that part for Pharo 7.
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?

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.
Hi torsten do you know if there is bug entry for this problem? Stef On Fri, Dec 29, 2017 at 11:59 AM, Torsten Bergmann <astares@gmx.de> wrote:
Hi, (cross posting vm-dev)
nssm is nice - but requires additional tools.
Since the days of Squeak the windows VM had the
-service "ServiceName"
option and one was able to run Squeak as a windows service out of the box.
See http://wiki.squeak.org/squeak/105 for details.
This option allows to register/deregister with the windows service manager and run a headless image.
I run a Squeak Wiki (Swiki/Comanche) since years with this and it is very nice and stable.
Unfortunately this is broken in recent Pharo VMs and so far Esteban or others did not have the time to look into this issue. Would be really nice if this option could be recovered in 2018. So one could easily deploy and run Seaside or Teapot/Tealight or Zinc/WebClient based web services on Windows.
If we want to deploy Smalltalk based web applications or services on Windows we should support that. It will keep Windows administrators happy and we would integrate with the whole ecosystem (for instance you can start/stop a service using Windows scripting for doing backups, etc.) right out of the box.
Bye T.

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

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.
