When all you have is Spec, everything looks like a nail?
by Sean P. DeNigris Sept. 2, 2014

Sept. 2, 2014

I've been mulling this over for a while, and since we've been having conversations about Spec's place in our future... DISCLAIMER: this is a visceral experience I've been having over a long period of time, so it may not be factually "true" or current, but I present it as a contribution, if only by someone saying "you're full of crap because..." and we all learn something. The purpose of Spec as I understand it is to both come up with a nice streamlined UI API, and to make multiple targets (e.g. Morphic, html) possible with the same codebase. These are both important goals. And it seems we've made some progress at least in the first case. I definitely enjoy working with Spec's API far more that e.g. PolyMorph. Spec could be a very valuable application-level tool. If I want to write a business application, I can write once via a nice API and deploy "anywhere". Life is good. My discomfort is with making *all* our core tools Spec-based. While it is great from an "eating our own dog food perspective", one of the great principles of Morphic is exploration and discoverability. Many times before Spec I was able to poke around a tool, figure out how it worked, and apply that lesson to my own UI. However, with Spec I find it extremely difficult to figure out WTH is going on. Parsing of arrays of symbols seems to have replaced Smalltalk code, and each field/model piece of a Spec UI seems to be buried behind multiple ValueHolder/Adapter/whatever levels. Granted, now that we have e.g. specialized inspectors, we might be able to alleviate this. My 2c. ----- Cheers, Sean -- View this message in context: http://forum.world.st/When-all-you-have-is-Spec-everything-looks-like-a-nai… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

NonInteractiveTranscript and Debugging issue in headless image
by phil＠highoctane.be Sept. 2, 2014

Sept. 2, 2014

I've got this error when the debugger is triggered in a headless image. So, #MNU. I had a look at the NonInteractiveTranscript and it has this method missing indeed in 3.0. I've added a basic one but we could benefit from enhanced debugging abilities on that front. As I am running on a server without any graphics abilities, it would be welcome to have this fixed. I added this to the startup script to patch the thing: Author fullName: 'PhilippeBack'. "Avoid yet another question..." NonInteractiveUIManager compile: 'openDebuggerOn: process context: context label: title contents: contentsStringOrNil fullView: bool ^ self nonInteractiveWarning: ''Opening Debugger''' classified: #'ui-requests'. So far so good, but it turned to: An attempt to use interactive tools detected, while in non-interactive mode Opening Debugger NonInteractiveUIManager>>nonInteractiveWarning: NonInteractiveUIManager>>openDebuggerOn:context:label:contents:fullView: SpecDebugger class>>openOn:context:label:contents:fullView: Process>>debug:title:full: GRPharoPlatform>>openDebuggerOn: in Block: [ process debug: anError signalerContext title: an...etc... And the vm stopped again. Looks like: NonInteractiveUIManager>>nonInteractiveWarning: aWarnMessage ^ ErrorNonInteractive signal: aWarnMessage isn't too friendly. How would one get debugging info shown and just proceed or close the debugger? Closing the image is really hard to swallow here. Ideas? Phil

[Article] Reddit.st - In 10 Cool Pharo Classes
by Sven Van Caekenberghe Sept. 2, 2014

Sept. 2, 2014

Hi, I published another introduction/tutorial article Reddit.st - In 10 Cool Pharo Classes Implementing a Reddit style web application in Pharo using Seaside, Glorp and PostgreSQL https://medium.com/@svenvc/reddit-st-in-10-cool-pharo-classes-1b5327ca0740 The focus is not so much on the smaller size or the higher developer productivity in Pharo, but more on the fact that we can cover so much ground using such powerful frameworks, as well as the natural development flow from model over tests and persistence to web GUI. This is a more intermediate level article that assumes basic knowledge about Pharo (language and IDE). https://ci.inria.fr/pharo-contribution/job/Reddit/ http://www.smalltalkhub.com/#!/~SvenVanCaekenberghe/Reddit Enjoy! Sven PS: This article is actually an update of an article that I wrote in 2010 and that became unavailable/outdated. -- Sven Van Caekenberghe Proudly supporting Pharo http://pharo.org http://association.pharo.org http://consortium.pharo.org

SqNumberParser and PGConnection in Pharo 3
by Esteban A. Maringolo Sept. 2, 2014

Sept. 2, 2014

So SqNumberParser is gone in Pharo 3. And the nextDateAndTimeFrom: in PGConnection refers to it... I replaced it by plain NumberParser and it seems to continue working. What is the approach here to have a "squeak compatible" PGConnection? Add an empty SqNumberClass as subclass NumberParser? Regards! Esteban A. Maringolo

Surrounding text in editors
by Torsten Bergmann Sept. 2, 2014

Sept. 2, 2014

Hi, 1. When I open a workspace and type Hello in it. Now I select the whole text and hit the $" key to make it a comment. This works, the workspace shows "Hello" on both sides and I can continue to work with my comment. 2. When I open a workspace and type Hello in it. Now I select the whole text and hit the $' key to make it a string. This does not works, the workspace again shows: "Hello" on both sides - which is a comment, but I would have expected a string: 'Hello' Is this a known problem. Is it related to Windows only - can one check on other platforms? Should we open an issue? Seems to work well for brackets and braces by the way: Selecting Hello with an additional $[ key gives correctly [Hello] Selecting Hello with an additional $( key gives correctly (Hello) Thx T.

Hi, does anybody know what #literals in RBSmalllintContext stand for? Because itâs calculated in a very weird way with the use of literalSemaphore and literalProcess variables. Uko

NeoJSON Mapping name-changing field
by Sean P. DeNigris Sept. 2, 2014

Sept. 2, 2014

The Flickr API returns a JSON object with two fields: 'status' and otherField, where the name of otherField depends on the API method. How do I handle mapping this second field with NeoJSONReader? Thanks ----- Cheers, Sean -- View this message in context: http://forum.world.st/NeoJSON-Mapping-name-changing-field-tp4775545.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Jenkins builds not properly preserving artifacts?
by Tim Mackinnon Sept. 2, 2014

Sept. 2, 2014

Guys - Iâve noticed that when a build completed on the Inria infrastructure, for a short time the console output correctly shows all the artefacts that were used to create that build - e.g. the slices loaded etc. However after a short time - the output then reverts to something like below (which isnât as useful): Started by upstream project "[8mha:AAAAqh+LCAAAAAAAAP9b85aBtbiIQTGjNKU4P08vOT+vOD8â¦. originally caused by: [URLTrigger] A change within the response URL invocation (log) Building remotely on pharo-contribution-winxp in workspace C:\builds\workspace\PharoLauncher Deleting project workspaceâ¦ done --- Iâve looked at a few other jobs (I noticed this for Pharo Launcher) and they seem the same. I think the jobs arenât configured properly? - As normally (at least in other languages like Java), the intent is that the console output reflects what was on the console when the job was run. I have a hunch that something is overwriting these files before they are archived away. As we donât seem to have other details of what went into a build job (which is another issue - I would expect the changes page for a build to also show this info in a better format). Do you think this could be fixed? tim
