funny idea Symbol vs. Selector
by stephane ducasse May 14, 2015

May 14, 2015

Hi guys I'm thinking aloud... I was wondering if we could not take advantage of a new class: Selector. MethodDict would only contain selectors and not symbols. I remember that I talked about that with hernan. Stef

Postmark email library
by Francois Stephany Aug. 31, 2013

Aug. 31, 2013

Hi guys, I've made a simple wrapper around the Postmark API. It lets you send emails without dealing with a SMTP server. You can read about it here: http://developer.postmarkapp.com/developer-libs.html http://developer.postmarkapp.com/developer-build.html and there: http://articles.tulipemoutarde.be/send-email-from-pharo-with-postmark It's pretty simple and naive implementation but it gets the job done. I'll add email attachements when I will need it. Francois

Package browser?
by Rob Vens June 28, 2013

June 28, 2013

I am attempting to do the Pharo by Example book, but a package browser (which is used in the examples) is not in the 1.1.1 or 1.2 image. Should I still use categories? If I create a package in Monticello browser I am not able to add classes or anything (not as far as I could see). Just starting out using Pharo, so apologies if these questions are already answered elsewhere.

Adding OAuth & OpenID support to Pharo
by Andy Burnett Dec. 20, 2012

Dec. 20, 2012

Hello, Now that we have added Websocket support to Zinc, I would like to move forward and add OAuth & OpenID. Sven Van Caekenberghe, and Jan van de Sandt, have put together a proposal, which my company would like to fund. If anyone feels that they would benefit from this - commercially - and would be happy to make a contribution to the development costs, please shoot me an email. All contributions are gratefully received. Cheers Andy

VAST-style Compile-time constants
by Bob Hartwig Nov. 27, 2012

Nov. 27, 2012

Hi all, I'm investigating the feasibility of porting a large VAST application to Pharo, so I may have some questions in the coming days. Here's my first question: VAST has the concept of compile-time constants, using the ##() syntax. Whatever is in the parentheses is evaluated at compile time, and the result is stored, so the evaluation does not need to happen again when the method is sent later. E.g., when this method is sent: printTheNumberToTheTranscript Transcript nextPutAll: ##( 10 factorial asString ) . no calculation or string conversion is necessary, because 10 factorial asString was evaluated at compile time and the answer was stored. Please note that this is different from array literals, which is how Pharo seems to treat this syntax. As far as I can tell, Pharo does not have this feature (certainly not with that syntax), but I would love to be proved wrong. Am I? Does anyone else have words of wisdom regarding porting a VAST app to Pharo? Any other language features that are missing? I'm not too concerned about Pragmas, and this app has no GUI, so I'm not concerned about UI framework differences. Thanks, Bob Hartwig

CollectionExtensions missing in Pharo 2.0
by Usman Bhatti Nov. 23, 2012

Nov. 23, 2012

Hello all, I remarked that the package CollectionExtensions is missing in Pharo 2.0. We are using a useful method provided by the package on strings that provides character intervals for line numbers in a string. Here is the code from 1.4: intervalOfLine: aLineNumber "Answer an interval spanning between the first and the last character of the line from aLineNumber" | lineIndex | lineIndex := 0. self lineIndicesDo: [ :start :endWithoutDelimiters :end | lineIndex := lineIndex + 1. lineIndex = aLineNumber ifTrue: [ ^ start to: end ] ]. ^ 0 to: 0 Now, this method is missing in Pharo 2.0. Is there a particular reason for omitting the package? Is there a replacement for the pckage? tx, Usman

FileTree queries
by Chris Nov. 21, 2012

Nov. 21, 2012

Hi, I've just migrated to using FileTree with SVN and am wondering if it is possible to use it without the monticello.meta? You obviously get a lot of merge conflicts with these and the version file in particular, and I didn't really see much benefit when using SVN for commit comments and revision histories and so forth so have just been ignoring / deleting them. It seems to work ok for the most part and by loading packages with Gofer, but I feel like I'm fighting the system a bit and have not had much luck with Metacello in particular which I would like to get working again. Can anyone advise? Thanks Chris
