[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. The website is at *http://www.smalltalkhub.com/#!/~Pier/Pillar*. Issues should be reported to *https://github.com/pillar-markup/pillar/issues* [3] http://wiki.squeak.org/squeak/3700 has some information about Pier. It refers to a Smallwiki mailing list which is active. https://www.list.inf.unibe.ch/pipermail/smallwiki/ e.g. https://www.list.inf.unibe.ch/pipermail/smallwiki/2016-November/008051.html with an announcment 'Pier3 with latest Pillar'

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.

Minimizing an Application

by horrido

I received this comment on Facebook: Smalltalk is a fantastic language and its development environment can't be beat... But the documentation for the many open source implementations is contradictory or confusing or missing. I can't speak for the commercial versions. Without an experienced mentor it is not possible to create a complex app. And even when you have done so, *I know no way to strip out the unused part of the image as well as the embedded source code*. ----- This issue of stripping out unused code seems to recur a lot. And truth be told, I've never seen a clear explanation of how to do this. Can someone provide clear direction? Is this documented anywhere? I'd like to use the information in future to assuage other people's concerns.

The Wisdom of the Crowd Redux

I'm glad people in the programming community are recognizing the value of Smalltalk: The Wisdom of the Crowd <https://medium.com/@richardeng/the-wisdom-of-the-crowd-c7aff954bd5f> .

Re: [Pharo-users] [ANN] Pharo wiki , is here

by Dimitris Chloupis

Yes Torsten wiki is in a very good state and very well made :) Will definitely link to it and use it as source As I said , I like to keep this as simple as possible, we are already hosted on github for documentation. A wiki there will be easier to find and easier to use and easier to maintain. On Mon, Aug 21, 2017 at 4:20 PM Esteban A.

This should be mentioned on ESUG imho, so people can propose and more people know about the talks.
