Web stack practices (Glorp / QCMagritte)

by laurent

Hi all, it's been a long time :) At work we are currently comparing several technologies to start a business project that will hopefully be used by thousands of people for several years ;) We need a web stack and we put Pharo & co in the comparative process. My team have strong experience in load-balanced php / mysql deployment that handles millions of records but we are ready to build on something else though MySQL is still a requirement. Thanks for Garage + Glorp, I can prototype things. I wonder how to handle database schema migrations. With our PHP projects we have versionned PHP scripts that are automatically run given a database revision number ( see http://git.afi-sa.fr/afi/opacce/tree/master/cosmogramme/sql/patch ). What are the practices with Glorp ? We try QCMagritte and we enjoy what we see so far. What are the best practices to glue Magritte and Glorp together ? Especially when you load-balance requests on several images. Some examples ? ( FYI, I cannot load QCMagritte in a fresh Pharo 6 image ( for #stable version, MADescriptionBuilder missing. For #development versions of Magritte and QCMagritte, QCConfiguration missing ). So actually I use the one built on CI. ) May be you have some other suggestions on a framework you love ? Best regards, Laurent Laffont

Indeed, it is a problem of the Zip library that does not unzip properly (no preservation of permissions, does not handle symlinks). It is a workaround but maybe I will add a strategy to use the unzip exe if I can find it on the system. That should solve most problems. WDYT?

Hi Sean-- > I'd like to create HTML via a DSL, like Seaside's canvas builder, but > without loading a whole web framework. Any ideas? In Pharo on the SqueakJS virtual machine in a web browser[1], I sketch with live DOM objects, and write them out as HTML. This way, the DSL is the actual JavaScript DOM API which is sitting in the web browser anyway, although driven with Smalltalk messages over the JS bridge. I'm also assured that everything I do with the DOM objects is legitimate, and I can handle DOM API errors live in Smalltalk. -C [1] https://caffeine.js.org/pharo -- Craig Latta Black Page Digital Amsterdam :: San Francisco craig(a)blackpagedigital.com +31 6 2757 7177 (SMS ok) + 1 415 287 3547 (no SMS)

I was writing Bootstrap support and saw that it was already available for Seaside and thought, darn it feels like unnecessary fragmentation here because these are all common, well-defined concepts! ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Continued Fractions

by phil＠highoctane.be

Do we have anything related to continued fractions in Pharo? https://en.wikipedia.org/wiki/Continued_fraction I need that to match rectanges to aspect ratios etc. TIA Phil
