Re: [Pharo-users] PharoLauncher eventual slowdown

Yeah I saw that when he was in Prague (incidentally that's where my launcher slowdown started :)). I've removed write access and will report back in couple of days. :) Thanks, Peter On Fri, Mar 4, 2016 at 11:24 AM, Damien Cassou <damien.cassou(a)inria.fr> wrote: > Hi Peter, > > Peter UhnÃ¡k <i.uhnak(a)gmail.com> writes: > > I've been using Pharo Launcher for quite a while and problem that I am > > constantly encountering is that launching of it becomes slower and > > slower. > > StÃ©phane, in CC, reported the same months ago on OS X.

Re: [Pharo-users] [Pharo-dev] Who is using Pharo Launcher and for what

Hi, PharoLauncher is my main entry point for creating / managing / launching Pharo images. I work at AFI and use Pharo for application monitoring & Redmine bug tracker analysis.

PharoLauncher eventual slowdown

by Peter UhnÃ¡k

Hi, I've been using Pharo Launcher for quite a while and problem that I am constantly encountering is that launching of it becomes slower and slower. Up until now I've solved it by writing a bash script that downloads the launcher fresh and reconfigures it. And then I've executed the script about once a week. But I am little bit fed-up by itâ¦ is this a common behavior? Or is it constrained to my machine? For example, if I execute the following (so I can time it) time /opt/pharo-vm/cog/pharo --nodisplay --textenc UTF-8 /opt/pharo-launcher/PharoLauncher.image eval '1+1' (also I have right now about ~27 images in the Launcher) fresh download (yesterday): ~0.49s today: 0.91s (almost double) and in a week it will be be maybe 10 seconds. I can just setup cronjob that resets pharo launcher every day, but a systemic solution would be better. Thanks, Peter

Re: [Pharo-users] Making STON exportation lighter

HI, There is a method in the class side of Object to override. This method return all the instVar name that need to be serialized. You can override it to store only the text. For example: Text class >>stonAllInstVarNames "Override to encode my instances using a custom set of instance variables or to define their order." ^ self allInstVarNames \ #runs On Thu, Mar 3, 2016 at 5:55 PM, Offray Vladimir Luna CÃ¡rdenas <offray.luna(a)mutabit.com> wrote: > Hi, > > I'm using STON as my notebook storage file format for grafoscopio[1].

Making STON exportation lighter

by Offray Vladimir Luna CÃ¡rdenas

Hi, I'm using STON as my notebook storage file format for grafoscopio[1]. One example of such notebooks is at [2], but they grow large easily. That's because STON serialize a lot of information of each node. A snipped of such info is something like [3], showed at the end of this mail. I remember that someone told me about a way to store only the #string part of the Text node, without any #runs or #values information in STON. How can this be done?
