Hi,

I have the following script that I run on mac:

wget -O- get.pharo.org/vmLatest60 | bash wget -O- get.pharo.org/60 | bash ./pharo Pharo.image eval "Smalltalk snapshot: true andQuit: true" ./pharo-ui Pharo.image

Initially I thought that it doesn't work but then I saw that it opens a very very small window with just a tiny scrollbar. Screenshot here: https://dl.dropboxusercontent.com/u/74244847/Data/Screen%20S hot%202017-03-29%20at%207.38.48%20PM.png.

Find attached a script for unix/mac os that sets the size of the screen in the image file.

Arguably the VM should use a window extent of 0@0 as a "start me headless" flag. What do people think? It would complicate things. The image would have to be located before any VM command line argument flags are processed, and probably opened twice. Seems like a lot of effort for little gain.

Cheers,

...

Andrei
