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

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

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

I know OP is talking about Windows... I've been running server applications on<br>
Linux without X11 with -vm-display-null and in-image RFBServer for access to<br>
Pharo over VNC. This works very well for me.<br>
<br>
I believe "real" headless means GUI is not run at all and therefore does not<br>
consume CPU cycles, which is very welcome. Meanwhile, maybe -vm-display-null<br>
works on Windows for scripting purposes?<br>

Hi Andrei,<br>
<br>
can you try this:<br>
<br>
Open Pharo normal (no headless option).<br>
Change the window size to "not-maximized" (eve if it is actually not maximized, maximize it ones and change it back to "not-maximized")<br>
Save and quit the image.<br>
<br>
After that, a call like<br>
<br>
pharo --headless pharo.image eval "DateAndTime now"<br>
will write the output to the stdout file, without opening a window.<br>
<br>
<br>
