Browse dependencies to a package
by Cyril Ferlicot D. May 14, 2018

May 14, 2018

Hi, In Pharo we have the dependency analyzer to get the dependencies of a package. But is it easily possible to find the dependencies to a package? I did not found the option in the interface. -- Cyril Ferlicot https://ferlicot.fr

Saving a Smalltalk Project
by horrido May 11, 2018

May 11, 2018

I received the following message: *We started off doing a small project in conservation in South Africa that involved tracking Rhinos in a remote GPS denied environment and ended up with some impressive building blocks for a Big Data Platform for IoT. The platform includes its own GIS subsystem and parts of an Expert System. Due to the choice made by my business partner and handful of contractors the platform ended up being built in Smalltalk on Squeak VM and the Magma Object Database. We now believe we may have the beginning of a commercial platform however its notoriously difficult to find Smalltalk developers so I am in half minds to migrate to a platform which uses a more mainstream language (Java / Python) as I have been getting some strange reactions from Angel Investors / VCs and mainstream developers. ... I wanted to ask you if you have information on how big the Smalltalk community is and whether its better to migrate to Pharo from Squeak and what types of recent industrial projects youve come across that use Smalltalk? Also I wondered if you know of any active smalltalk group in Silicon Valley and what are the best forums for professional SmallTalk development.* I would very much like to save their project as a Smalltalk project. The principal issue seems to be finding enough Smalltalk developers. I don't know if they need on-site developers or if remote developers can pass muster. I strongly suspect the former. How hard would it be to find Smalltalkers willing to work in Silicon Valley, or South Africa? What is the best response to this person? Thanks. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Metacello load in code vs. Iceberg menu install? Can you automate remote loading?
by Tim Mackinnon May 10, 2018

May 10, 2018

Hi - Iâm trying to automate the deployment of a seaside image to Digital Ocean. I was following the Enterprise Pharo booklet - and its a bit out of date, but I wanted to do the bit about taking a clean image and then loading in my project which Iâve stored in Git using Iceberg. So on the command line I am trying to eval â Iceberg enableMetacelloIntegration: true. Metacello new baseline: 'PagerDuty'; repository: 'git@gitlab.com:macta/WillowPagerDuty.git'; load.â But I get retry errors and a walkback, so Iâve tried to do the same in the playground in a fresh image and its true - I get an error because ZnClient is trying to connect to a url like "http://:80/git@gitlab.com:macta/WillowPagerDuty.git/?C=M;O%3DD <http://:80/git@gitlab.com:macta/WillowPagerDuty.git/?C=M;O=D>â (so it interprets that git@ specification strangely). But what is weird, is that if I use Iceberg - connected to the same repo (and specified the same way) - and then use the Metacello - Install baseline menu (right click on the BaselineOfXXX package) it then works perfectly. So whatâs the difference? It looks like the latter is mapping down to a "repository: 'gitlocal://', packageDir;â whereas the above is trying to read it over the wire? I then tried using an access token for gitlab, so its an https variant - but that gave me an error as well? Does this mean to automate I have to bring down the initial BaseLine - but then if that baseline refers to others - that seems to work, so Iâm a bit confused about what is going on? Tim

Serializing Excpetion with Fuel on the production and opening debugger on the dev machine - hot to? [Pharo 5]
by Petr Fischer May 10, 2018

May 10, 2018

Hello, what is the current procedure for achieving %subj%? I am on latest Pharo 5. I am serializing server side exception with: FLSerializer serialize: anException toFileNamed: 'something'. But how to open a debugger after materialization on the "dev machine side"? I found (Google, Mailing list) some examples, but it's obsolete (the debugger class no longer exists in Pharo 5 etc etc). Thanks! Petr Fischer

Tonel, Pharo 6.1 and file per class?
by Tim Mackinnon May 10, 2018

May 10, 2018

Hi guys - With all the talk about iceberg changes, Iâve stayed away from it for a bit (6 months) - but downloaded a new 6.1 image a few weeks ago and went to version some stuff yesterday into a new project. Iceberg seems a bit more stable - but it still seems to write out individual methods as files which I thought had been changed? Am I doing something wrong - or do i need to set something?

> {self meth1. self meth2. self meth3} This is not possible in a reasonably general way. Usually I end up writing it like `Array with: self meth1 with: self meth2 with: self meth3` On Tue, May 8, 2018 at 3:31 PM, Davide Varvello via Pharo-users < pharo-users(a)lists.pharo.org> wrote: > > > ---------- Forwarded message ---------- > From: Davide Varvello <varvello(a)yahoo.com> > To: pharo-users(a)lists.pharo.org > Cc: > Bcc: > Date: Tue, 8 May 2018 06:31:46 -0700 (MST) > Subject: Re: How to pretty print a dynamic array > Thanks Ben, I'm gonna try > Cheers > Davide > > > Ben Coman wrote > > On 8 May 2018 at 04:22, Davide Varvello via Pharo-users < > > > pharo-users@.pharo > > >> wrote: > > > >> > >> > >> ---------- Forwarded message ---------- > >> From: Davide Varvello < > > > varvello@ > > > > > >> To: > > > pharo-users@.pharo > > >> Cc: > >> Bcc: > >> Date: Mon, 7 May 2018 13:22:58 -0700 (MST) > >> Subject: How to pretty print a dynamic array > >> Hi guys, > >> I have a dynamic array that the formatter put on a column like this: > >> {self meth1. > >> self meth2. > >> self meth3} > >> > >> instead I want it in a single row, like this: > >> {self meth1. self meth2. self meth3} > >> > >> But I can't find any settings to pretty print in the last way. > >> Can you help me, please? > >> > > > > Hi Davide, > > > > I'm not sure I can be much help since I never use the pretty printer and > > I'm not familiar with the system. > > There may be a setting for that, but if not and I wanted to find out > about > > how to do it > > I'd take the shotgun approach.... > > > > In System > Settings, search for "pretty" and the with some setting > > related > > to newLines, > > some line "New line After Cascade" > > then "Browse" it, then in the body of the method find that text again > > and look for senders attached selector. > > > > That brought me to " BIConfigurableFormatter >> visitCascadeNode: " > > and browsing that method in the System Browser shows a bundle of other > > "visitXXX" methods. > > Drop a "self haltOnce" in an interesting one and try to trigger when you > > pretty print. > > Trace through a few times to learn how it does its stuff, and see if you > > can change it to do what you want. > > > > > > -- > Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html > > >

#ast vs. #parseTree

Why does CompiledMethod understand both? They are in the same protocol, produce the same kindOf result, and neither has a method comment! :/ (Pharo 4.0) ----- Cheers, Sean -- View this message in context: http://forum.world.st/ast-vs-parseTree-tp4893074.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Hi, has anyone played around with customizing the red screen of death (=morphic/athens drawing error)? Perhaps to show something similar to what chrome shows on a tab crash Thanks, Peter

There may be a setting for that, but if not and I wanted to find out about how to do it I'd take the shotgun approach.... In System > Settings, search for "pretty" and the with some setting related to newLines, some line "New line After Cascade" then "Browse" it, then in the body of the method find that text again and look for senders attached selector. That brought me to " BIConfigurableFormatter >> visitCascadeNode: " and browsing that method in the System Browser shows a bundle of other "visitXXX" methods. Drop a "self haltOnce" in an interesting one and try to trigger when you pretty print. Trace through a few times to learn how it does its stuff, and see if you can change it to do what you want.
