Alistair Grant wrote > https://github.com/akgrant43/Pharo-Chrome Wow, that was a wild ride! Lessons learned along the way: 1. On a Mac, to use the snazzy `chrome` terminal command referenced all over the place in the docs, you must first `alias chrome="/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome"` 2. Chrome must be started with certain flags: `chrome --remote-debugging-port=9222 --disable-gpu` (not sure if the last flag is needed, but `#get:` seemed to hang before using; reference https://developers.google.com/web/updates/2017/04/headless-chrome) 3. Beacon has renamed InMemoryLogger to MemoryLogger 4. I guess Beacon has renamed `#log` to `#emit` 5. I had to comment out `chromeProcess sigterm.` because `chromeProcess` was nil and also #sigterm seemed not to be defined anywhere in the image. I'm not sure what the issue is there. Pull request issued for #3 & #4. Also, I'm not sure what platforms you support, but you may want to tag the example methods with <gtExample> or similar so that they are runnable from the browser and open an inspector if there is an interesting return value. ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Hi stefan I'm interested. So if you want that I do code review and ask super dumb questions let me know.

Re: [Pharo-users] RewriteTool maintained?

by Stephane Ducasse

Probably. Mark decided not to do a PhD with us and the company with which he did his master. Now may be he is still following this list. May be we will rescue his tool. I do not know where it is saved. Stef On Sat, Nov 11, 2017 at 2:21 PM, Peter UhnÃ¡k <i.uhnak(a)gmail.com> wrote: > Hi, > > has Mark Rizun's Rewrite Tool been abandoned? > > Thanks, > Peter

Yes because what people see is just open a window. But inside we are trying our best to REALLY improve and it will pays off because having a powerful infrastructure will let us reinvent ourselves. > > I don't have enough time to look into Pharo as much as I would and just by > reading the mailing lists and just dipping my toes into Pharo from time to > time, I sometimes get the impression Pharo is moving so fast I just can't > follow.

Git is a modern distributed version system (it looks simple at first and may be super complex) :) Iceberg is a toolsuite and model to support git access from Pharo. We try to avoid to force people to do everything from the command line and provide abstraction also to manage Pull Requests which are not related to git but to github. >> Now if people like vikenti wants our support.

Sounds like this is another area in which you guys are moving much faster than it looks from the outside. I don't have enough time to look into Pharo as much as I would and just by reading the mailing lists and just dipping my toes into Pharo from time to time, I sometimes get the impression Pharo is moving so fast I just can't follow.

It may have been clear, but Laucher is to manage multiple development images, not for deployment (although it uses some tricks that may be useful for deployment like making the tool fullscreen) ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

I want Pharo to be comfortable tool for application development. Like Delphi or C++ (where i came from but don't want to get get back to, after Smalltalk any other platform seems imperfect for me). We want the same but we are not yet there. I want APPLICATIONS not just code loaded into Pharo. > > Faithfully yours, Vikenti Potapov. > >

Joachim We are focused on deployment but not the same way. We are the first system that bootstrap a core and can load dependencies on this core. We have a dependency analyser that is really advanced since it can check that you have message that are not in extension of packages that you use. In January I hope that we will start packaging Applications (versus packaging code), so that people can deploy desktop applications more easily. Now if people like vikenti wants our support. They should learn how to engage a discussion with us and not just complain :) Stef On Sun, Nov 12, 2017 at 6:02 AM, jtuchel(a)objektfabrik.de <jtuchel(a)objektfabrik.de> wrote: > Am 11.11.17 um 22:29 schrieb ÐÐ¸ÐºÐµÐ½ÑÐ¸Ð¹ ÐÐ¾ÑÐ°Ð¿Ð¾Ð²: > > Vikenti, >> >> And also i mean some simple and understandable deployment tool (as in >> Cincom VW exists) but not manual-written bash scripts.
