Brisbane
by Jeff Gray April 7, 2017

April 7, 2017

Hi all, Just an update. I just attended my third Smalltalk meet-up in Brisbane. It's a small group but hopefully we can grow as we gain momentum. We are just now setting up our team and initial project in Smalltalk Hub. We are meeting once a month in a great little venue by the river with free fast Wi-Fi and good cheap coffee. I have been just hacking in Pharo on my own for a while now. I am looking forward to working in a team environment, adding some rigour to my testing and sharing techniques and approaches. -- View this message in context: http://forum.world.st/Brisbane-tp4941489.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Voyage and attributes references
by Hilaire April 6, 2017

April 6, 2017

Hi, Here is another scenario where I have trouble with Voyage: Let's an object A, with an attribute an object Address. Then I create B, a copy of A. Of course the object Address is both an attribute of A and B. (no deep copy). As long as my Voyage repo is running, editing Address from A or B is doing fine: when editing Address from A, I can see this reflected in B's Address, as expected. Sadly, this Object scheme is lost in the persistency: when I reset the repo, shutdown it, restart it, to force a full retrieve from the Mongo repo, object A and B do not share anymore the Address object has it should be. I understand Voyage is not a true really Object Oriented repository, but is it possible to overcome such limitation? One idea will be to have collection of Address, but this really looks strange to me. I think Fuel was doing just fine with such scenario, but sadly Fuel is not reliable between images. Thanks to read up to here. Hilaire -- Dr. Geo http://drgeo.eu

PetitParser question parsing HTML meta tags
by PAUL DEBRUICKER April 5, 2017

April 5, 2017

This is kind of a "I'm tired of thinking about this and not making much progress for the amount of time I'm putting in question" but here it is: I'm trying to parse descriptions from HTML meta elements. I can't use Soup because there isn't a working GemStone port. I've got it to work with the structure: <meta name="description" content="my description"> and <meta name="Description" content="my description"> but I'm running into instances of: <meta http-equiv="description" content="my description"> and <meta http-equiv="Description" content="my description"> and am having trouble adapting my parsing code (such as it is). The parsing code that addresses the first two cases is: parseHtmlPageForDescription: htmlString | startParser endParser ppStream descParser result text lower str doubleQuoteIndex | lower := 'escription' asParser. startParser := '<meta name=' asParser , #'any' asParser , #'any' asParser. endParser := '>' asParser. ppStream := htmlString readStream asPetitStream. descParser := ((#'any' asParser starLazy: startParser , lower) , (#'any' asParser starLazy: endParser)) ==> #'second'. result := descParser parse: ppStream. text := (result inject: (WriteStream on: String new) into: [ :stream :char | stream nextPut: char. stream ]) contents trimBoth. str := text copyFrom: (text findString: 'content=') + 9 to: text size. doubleQuoteIndex := 8 - ((str last: 7) indexOf: $"). ^ str copyFrom: 1 to: str size - doubleQuoteIndex I can't figure out how to change the startParser parser to accept the second idiom. And maybe there's a better approach altogether. Anyway. If anyone has any ideas on different approaches I'd appreciate learning them. Thanks for giving it some thought Paul

Build Pharo VM with --dynamic-linker
by Alistair Grant April 5, 2017

April 5, 2017

Hi All, I'm still working on getting Pharo packaged with snapcraft. The latest hurdle is that 32 bit applications won't load correctly because the snapcraft environment means that ld-linux.so.2 isn't in the expected location. My understanding is that adding the appropriate --dynamic-linker flag should solve the problem, defining: export LDFLAGS="-Wl,--dynamic-linker=/snap/pharo/x1/lib/ld-linux.so.2" successfully builds, but the pharo executable still has the default location: $ strings pharo-vm/pharo | grep ld-linux /lib/ld-linux.so.2 Can someone point me to where I should modify the build scipt(s) so I can set --dynamic-linker appropriately? Thanks! Alistair

April 4, 2017

Hi When writing grammar I would like to test the scanner. And I would like to this without having to define a special rule (in addition to the one of the language). Is it possible to get access to the scanner and ask it to scan the stream? Stef

Notifications with more details (something like improved #inform:
by Offray Vladimir Luna CÃ¡rdenas April 4, 2017

April 4, 2017

Hi, Nowadays task bar in several desktop environments gives you a condensed view of notifications and in you click on them, can see detailed notifications. For example they show a notification saying "5 new telegram messages" and you click on the notification and shows individual messages. We have #inform: but if you use it for several notifications they pile up and soon becomes unmanageable. Do we have something like that desktop notifications with more details in Pharo? Thanks, Offray
