hi, no idea :) as I said this is more a matter for Amber list than Pharo. but amber maintainer (Herbert) hangs here so he will probably reply if he sees this :P Esteban > On 21 Mar 2018, at 21:42, in_pharo_users(a)nym.hush.com wrote: > > Hi Esteban, > > after I got Amber running separately, I set up Tide according to > > https://github.com/tide-framework/tideÂ <https://github.com/tide-framework/tide%C2%A0>; readme.md > > Everything went fine so far, but after the page loaded, Helios did not pop.

Problem setting up Tide demo

by in_pharo_users＠nym.hush.com

Hi Esteban, after I got Amber running separately, I set up Tide according to https://github.com/tide-framework/tide readme.md Everything went fine so far, but after the page loaded, Helios did not pop. Blank page. So I looked into the page source and, suspiciously, at line 18 I found **** require( [ "amber/devel", "amber/helpers", "tide/Tide-Amber-Core", "tide/Tide-Amber-Exceptions", "tide/Tide-Amber-Examples", "tide/Tide-Amber-Tests" ], function (smalltalk) { smalltalk.initialize({defaultAmdNamespace: 'tide'}); smalltalk.popupHelios(); } **** I searched for all required paths in the bower path, but could not find only the first two. Can you kindly give me a hint how to proceed to get it running? Kind regards, basket

Re: [Pharo-users] How to model extension method in UML

by Stephane Ducasse

I would package extension in the package doing them and use a stereotype <extension> to capture this because UML does not have this concept.

Have you left in that ui close statement that was in your first post? I tried you code and it worked fine - but if you issue a close you'll have nothing to see! -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] Yet another Pharo in docker

by Herbert VojÄÃk

BTW, Sean (or anyone else), if you still find this docker useful, should I add you as contributor in dockerhub and write access in git so you could make builds for 70 (I do not use 70, so not knowing when is it the good point to make new build). Or is there some ETA to official one built from Pharo jenkins itself? Herby Herbert VojÄÃk wrote: > > > Herbert VojÄÃk wrote: >> >> >> Sean P. DeNigris wrote: >>> Sean P.

Re: [Pharo-users] Porting Transducers to Pharo

I think I used FileOut30 and encodings were part of the adhoc fixing before loading into Pharo (using iconv certainly, but I don't recall) On 21 March 2018 at 14:29, Esteban A.

What was the choosen tool? I tried FileOuterNG but it doesn't work in VW PUL 8.2, and I don't understand the reasoning behind the "bindings" mappings (it fails when building the default mappings). The FileOut30 package doesn't seem to respect encodings at all. Thanks! Esteban A. Maringolo
