there are two binaries one is pharo-ui that displays the gui and one is pharo that does not use the GUI , because I use pharo and not pharo-ui , i do not need -vm-display-null and does not solve my problem of not exiting On Mon, Nov 28, 2016 at 1:25 PM Thierry Goubier <thierry.goubier(a)gmail.com> wrote: > 2016-11-28 12:13 GMT+01:00 Dimitris Chloupis <kilon.alios(a)gmail.com>: > > How to execute a script from command line , then save the image and exit ? > > I use the st command but it offers either --save which saves but keeps > image opened or --exit the exits the image without saving > > ./pharo Ephestos.image st --save test.st > > > Use an option like -vm-display-null with -save.

Re: [Pharo-users] ZnClient GET, but just the content of the <head> tag?

by jtuchel＠objektfabrik.de

I wonder if it is a hard requirement to transport your info as part of the html page. A possible alternative might be to just use a HEAD request instead of GET and transport your info "on the bare HTTP layer"?

Re: [Pharo-users] [SmaCC] Partial Installation

by Dimitris Chloupis

Thank Thierry you pointed me to the right direction and after that because I knew what the problem was I found the solution, it needs the addition of the require message to create a group that is then loaded . I have corrected the baseline https://github.com/kilon/Ephestos/blob/master/BaselineOfEphestos.package/Ba… it now works like a charm :) Awesome On Sun, Nov 27, 2016 at 12:48 AM Thierry Goubier <thierry.goubier(a)gmail.com> wrote: > Le 25/11/2016 Ã 23:16, Dimitris Chloupis a Ã©crit : > > The version does not matter, the configuration get the github repo as is > > .
