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

Voyage: image freeze/VOMongoError: Lazy reference not found
by Sabine KnÃ¶fel Aug. 31, 2013

Aug. 31, 2013

Hi Esteban, sorry but I need your help again. I succeeded in re-writing all my code to use voyage and can save all my model now. Great! Now I was experimenting with it and I have an Image freeze which should not occur in production;-). Situation: I created one Person with two trips. Trip points back to its person. After writing it into mongo, I delete one trip from mongo manually (I use rockmongo, great tool). So in the database, I have now 1) one Person which points to two trips 2) one trip (the other was deleted) Now, I do: Person selectAll first trips and the image freezes. Sometimes, I find in the DebugLog: VOMongoError: Lazy reference not found RKATrip: OID(103475906) This is correct ;-) I did also try with enableMissingContent but did not work. http://forum.world.st/Voyage-GC-collecting-random-objects-td4668438.html Sure, normally, we do not manipulate the database manually. But I want to be sure that the image does not freeze if this occurs.... How can I solve this? regards Sabine ########################################### with this filein you can reproduce it easily ########################################### Object subclass: #Person instanceVariableNames: 'trips lastName' classVariableNames: '' poolDictionaries: '' category: 'RKA24-Demo'! !Person methodsFor: 'accessing' stamp: 'sabineknoefel 8/15/2013 10:02'! lastName ^ lastName! ! !Person methodsFor: 'accessing' stamp: 'sabineknoefel 8/15/2013 10:02'! lastName: anObject lastName := anObject! ! !Person methodsFor: 'accessing' stamp: 'sabineknoefel 8/15/2013 10:02'! trips ^ trips! ! !Person methodsFor: 'accessing' stamp: 'sabineknoefel 8/15/2013 10:02'! trips: anObject trips := anObject! !

How send message with non-ascii characters via SMTP
by vmusulainen Aug. 29, 2013

Aug. 29, 2013

Hi! I try use SMTPClient from Network-Protocols. It fine work for message with only english characters at body or subject. But if add non-english (non ascii) characters and encoding it, that mail client (web interface gmail) don't encode message My code (It's code from another post in this forum): message := MailMessage empty. message setField: 'from' toString: '[my mail]'. message setField: 'to' toString: '[you mail]'. message setField: 'content-type' toString: 'text/plain;charset=utf-8'. message setField: 'subject' toString: (((GRCodec forEncoding: 'utf-8') encode: 'Encoding test â¬â¬â¬')) . message body: (MIMEDocument content: 'test') "((GRCodec forEncoding: 'utf-8') encode: 'MotÃ¶rhead â¬' ))". client := SMTPClient openOnHostNamed: '[mail server]' port: 25. client user: '[user]'; password: '[password]'. client login. client mailFrom: message from to: (Array with: message to) text: message asSendableText. client quit. client close.

SmalltalkHub markdown preview annoyance when testing URL links
by btc＠openinworld.com Aug. 29, 2013

Aug. 29, 2013

I'm just starting to use SmalltalkHub (and it is very slick) but I bumped into something particularly annoying. When creating a project, the Description field has a preview link (which is cool that I can view my markdown, thankyou). Within this preview, test clicking a URL link replaces the original SmalltalkHub page and clicking back presents me with a blank 'Create new project page'. Arrgh! It easy to avoid doing this a second time, so for me its a low priority, but just reporting it something to add to the todo. The less surprises the better for newcomers. I am surprised I hadn't seen anyone mention it previously. Is there an issue tracker for SmalltalkHub somewhere that I missed? cheers, Ben

Whole class hierarchy in System Browser
by Esteban A. Maringolo Aug. 28, 2013

Aug. 28, 2013

Hi, Is there a way I can browse the whole class hierarchy in the SystemBrowser? I mean, a big tree with Object (or ProtoObject as its root) without having to filter branches it by categories. I have two groups of categories (one starting with T and the other one with G) and the names are too separated in the list. Clicking back and forth is a real hassle. Thank you! -- View this message in context: http://forum.world.st/Whole-class-hierarchy-in-System-Browser-tp4705331.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Rearranging tests between categories
by Stephan Eggermont Aug. 27, 2013

Aug. 27, 2013

You are remembering 'reorganize categories' (that only works for packages and their classes). I'm not sure where that has gone in Nautilus (the new browser). You may want to take a look at SystemNavigation and friends. Then you can make these changes programmatically. You probably want to experiment on a copy of your image... Stephan
