The T-shirts look great. Here's the mock-up: [image: black shirt.jpg] They've been shipped to the JRMPC teams where I'm sure they'll be a big hit. If any of you like the design, you're welcome to use it for your T-shirts. I'm putting it out into the public domain. Here's the T-shirt design (SVG): https://drive.google.com/open?id=1GV4f9LBMdCdTcgjPR82n61mezaCqg3O1 Richard

There is a twilio library for pharo here: https://github.com/newapplesho/twilio-smalltalk Maybe you could learn what you need to do from it?

by Roelof Wobben

Hello, I wonder if I can solve the TwillioQuest with Pharo. I then have to write code to send SMS and return a respons a a SMS. is this possible in Pharo and can I use for example teapot for it ? and if it possible does anyone have a example of how to send a SMS with Twillio. Regards, Roelof

This is cool.

[ANN] Grouper

by Julien Delplanque

Hello, I made a small library that reify grouping (that one does via #groupBy: usually): Grouper https://github.com/juliendelplanque/Grouper It is designed in the same spirit as SortFunction, but for grouping. Quick example: The following code snippet using Grouper: (10 to: 50)groupUsing: [:integer | integer asString first ]. "an OrderedDictionary( $1->#(10 11 12 13 14 15 16 17 18 19) $2->#(20 21 22 23 24 25 26 27 28 29) $3->#(30 31 32 33 34 35 36 37 38 39) $4->#(40 41 42 43 44 45 46 47 48 49) $5->#(50))" is equivalent to the following code snippet using built-in|#groupedBy:|method: (10 to: 50)groupedBy: [:integer | integer asString first ] "an OrderedDictionary( $1->#(10 11 12 13 14 15 16 17 18 19) $2->#(20 21 22 23 24 25 26 27 28 29) $3->#(30 31 32 33 34 35 36 37 38 39) $4->#(40 41 42 43 44 45 46 47 48 49) $5->#(50))" The advantage of using it is that it allows one to compose grouper objects. Thus, it is easy to describe grouping on 2 or 3 levels. Fore example: The power of Grouper is that group description are first-class objects. Thus, it is possible to compose group descriptions in order to group a flat collection on multiple levels. For example: groupComposition:= [:integer | integer asString first ] grouper , [:integer | integer asString second ]. (10 to: 50)groupUsing: groupComposition. "an OrderedDictionary( $1->an OrderedDictionary( $0->#(10) $1->#(11) $2->#(12) $3->#(13) $4->#(14) $5->#(15) $6->#(16) $7->#(17) $8->#(18) $9->#(19)) $2->an OrderedDictionary( $0->#(20) $1->#(21) $2->#(22) $3->#(23) $4->#(24) $5->#(25) $6->#(26) $7->#(27) $8->#(28) $9->#(29)) $3->an OrderedDictionary( $0->#(30) $1->#(31) $2->#(32) $3->#(33) $4->#(34) $5->#(35) $6->#(36) $7->#(37) $8->#(38) $9->#(39)) $4->an OrderedDictionary( $0->#(40) $1->#(41) $2->#(42) $3->#(43) $4->#(44) $5->#(45) $6->#(46) $7->#(47) $8->#(48) $9->#(49)) $5->an OrderedDictionary($0->#(50)))" On the github, there are more example showing how to build trees with custom objects. Any feedback for this library is welcome. I would like to propose it to Pharo in the near future because it would simplify a lot of code in DrTests (related to result tree views, the tree on the right of the UI). I don't know if it will be possible before next release as we are in feature freeze. Cheers, Julien

[ Example ] ZnKeyValueStore

by Sven Van Caekenberghe

Hi, I added a new example to Zinc HTTP Components, a simple in-memory key-value store exposed as a REST web service (ZnKeyValueStoreDelegate) and a client to access this service over HTTP (ZnKeyValueStoreClient). Check the class comments for a more detailed explanation. ZnKeyValueStoreTest #testUsage and #setUp implement a runnable example and functional test. You will have to load the latest version of Zn from https://github.com/svenvc/zinc Sven -- Sven Van Caekenberghe Proudly supporting Pharo http://pharo.org http://association.pharo.org http://consortium.pharo.org

Re: [Pharo-users] [ANN] ReStore for Pharo - object<>relational database framework

by TomaÅ¾ Turk

Hi, ReStore looks quite sleek, thank you for your nice contribution! I wonder if we could "hook it up" with PharoADO. When I find some time, I can look into the approach you took in SSW ReStore P3 and SSW ReStore UDBC SQLite. For Glorp, you basically just need to send an SQL query that Glorp prepares directly to DB and pack the received resultset into an array structure.
