Re: [Pharo-users] How do I get a list of all packages in the catalog with a 6.0 tag?

You can use the Catalog Browser? In tools. Is it not what you are looking for? Stef On Mon, Aug 21, 2017 at 3:58 PM, H.

Re: [Pharo-users] Where is the installation log? Installing FileMan into Pharo 6.0-60510, which is 6.1.

Glorp: Is there some way to do insert-or-update?

by Herby VojÄÃk

Hello! Is there some way to do insert-or-update operation (that is, roughly, to be able to register an object with possibly existing primary key(s) and let it be written regardless? Thanks, Herby P.S.: Use case - I want to have log of USER-DEVICE pairing with last timestamp and 'enabled' field that would be set to false once push notification fails - but set to true once user actually logs from the device (again). I don't want to have many historical records, so I want to have USER+DEVICE to be a composed primary key. Which means it is inserted first time, but possibly updated later.

[Wanted] Newsletter topics and "takeovers"

by Marcus Denker

Hi, As you for sure know, we have now a good monthly rhythm with the newsletter. http://us11.campaign-archive1.com/home/?u=6f667565c2569234585a7be77&id=0486… <http://us11.campaign-archive1.com/home/?u=6f667565c2569234585a7be77&id=0486…> And the number of subscribers is growing! If you have ideas for the next newsletters (August is done and will be posted soon, but we need content for September and laterâ¦) We need both small and larger items. Example for smaller news: - announcements of new libraries - new releasese - links to videos - links to blog posts And larger items. These have not just the title and link, but a short description and if possible a picture. (If you look at the older newsletters it should be clear what is needed). Another idea I had: we could even have âcomplete takeoverâ of a newsletter by someone who wants to edit a newsletter for one specific topic. This can be about one project, or just a âthemeâ (e.g. âcloud deployment with Pharoâ) if you are interested â> send a mail to board(a)pharo.org <mailto:board@pharo.org> Marcus

Where do I find a Pillar syntax summary?

by H. Hirzel

Hello There is a tutorial for the Pillar document writing system [1]. The Pharo 6 catalog entry shows that the Pillar syntax goes back to the Pier CMS syntax of Lukas Renggli [2]. There is a syntax summary for the Pier CMS http://www.piercms.com/doc/syntax [3] I assume that most this still applies for Pillar? But I can imagine that there have here been updates / changes / extensions. I am looking for a Pillar syntax summary ("cheat sheet"). Is this available somewhere? Kind regards Hannes [1] https://ci.inria.fr/pharo-contribution/job/EnterprisePharoBook/lastSuccessf… [2] Pharo 6.1 catalog entry for Pillar Pillar is a wiki-like syntax, its document model, a parser for it, and a set of exporters (e.g., HTML, LaTeX, Markdown...). Pillar is primarily used as the wiki syntax behind the *Pier CMS>http://piercms.com*. Pillar is also being used to write books: e.g., *the Enterprise Pharo book>http://books.pharo.org/*. The original creator of Pillar (formerly known as ''the syntax behind the Pier CMS'') is Lukas Renggli. Nevertheless, *Damien Cassou>damien.cassou(a)inria.fr* is now the maintainer.

Re: [Pharo-users] Minimizing an Application

by Richard Sargent

VA Smalltalk doesn't strip an image; it builds a new image based on application dependencies. With VA's packaging functionality, you are more likely to get a packaging error that reports you are trying to use something that isn't reachable according to the defined dependencies. I admit that except for the first few years, most of my early Smalltalk experience involved ENVY and VA/VisualAge Smalltalk. Still, I prefer it's practice of building an image based on what you have told it to include.

Re: [Pharo-users] Minimizing an Application

by Tim Mackinnon

There has been a lot of great work on this front on the Pharo side from the "team" and PharoLambda has made use of it (although it's a tiny project). My footprint is ~22mb including vm & image. And leaving out sources. The ./scripts directory has the example of how to do it, along side the .gitlab-ci.yml file. Unlike the commercial distributions (and this may have changed recently), there is a minimal image you can have download, which has enough to bootstrap loading your project via metacello. There are no browser tools or morphic things in the starting image I have chosen. You can potentially get smaller - but it's a decent result. The only bit I added was to remove testcases (optional), and clear down metacello. It's probably worthy of a blog post - but honestly the running example is pretty straight forward. The commercial tools all have a decent "strip dead code" tool, that does a similar thing in reverse - which is equally a decent way of approaching the problem and can lead to even tinier results.
