Re: [Pharo-users] Pillar used directly from Pharo

by Cyril Ferlicot

Hi again ! Ok so. To use pillar inside Pharo you have this: PRCocoonConfiguration new templateStream: PRHTMLWriter defaultTemplate; configurations: Dictionary new; inputFiles: {(FileSystem workingDirectory / 'test.pillar')}; outputType: PRHTMLWriter; outputFile: 'test.html' asFileReference ; export. Here is a little exemple. You can remplace PRHTMLWriter by PRLaTeXWriter, PRTextWriter, PRMarkdownWriter, PRPillarWriter etc... The outputFile is the name of the file you want to be generate, the file will be on the folder of the image. If you want a special template you have to pass it to templateStream. You can also have others option like: - inputString : aString with the pillar text you want to export like: '!test *myLink>http://test.html* !!Test 2 etc...' - outputStream : if you don't want a file at the end but a stream. etc... You can find all these option inside the PRCocoonConfiguration class. I hope that can help you, if you've others question fell free to ask !

Yes, finding the right level between very deep technical (the first one) and just showing the things we made really easy (the later ones) is difficult. There is a frustrating gap in the middle. It doesn't help that Diego is very busy with non-pharo things atm, and that I have a few points that I would like to improve before explaining them... > Maybe could we do a paired session with a walkthrough, record all of it > and push it on YouTube. > > What do you think? I am educated enough on Magritte to follow I think. Sounds like a good idea. I'll talk to Diego. > Magritte is powerful but comes with the uber-frustration factor :-) > Let's alleviate that. Yes, finding your way in Magritte is difficult. We need some kind of cookbook. I'm playing on too many chessboards at the same time atm, and the lack of finishing is frustrating. Stephan

That is exactly what we provide with QCMagritte. And yes, it is difficult to find out where to make changes, because the number of interacting parts is rather large. The essential complexity when integrating rights and roles, i18n, bootstrapping the components, providing a navigation model, and ajaxifying, is larger. If you try integrating these yourself in Magritte, you'll end up with mostly the same abstractions, or a lot of duplication Stephan

Re: [Pharo-users] Looking for Magritte example: MAAddress, MAPerson...

by phil＠highoctane.be

I have a collection of docs about Magritte I collected over time and made some examples when I was trying to get it integrated in one software. I took a while to wrap my mind around it and reading Luka's thesis was helpful. I also realized that there were missing pieces for some associations I wanted. Maybe we should start a shared effort on this in the form of a pillar book (maybe there is one somewhere already). QCMagritte is interesting but I do not feel like looking into it, as it is hard to wrap my mind around it. My main concern with Magritte at this point is that it takes significant effort to get a decent CRUD system working. What I have got is okay for prototyping but the UI seems very bland compared to what I can do using WATableReport extensions and Mold. This hasn't to be like that but as Quuve showed, one needs to make all of the subclassed parts and mechanisms to get it nice. This is really an area where we are lagging behind. It is annyoying since competing technologies do have what it takes to make decent crud systems. In TikiWiki CMS groupware, we've got a thing callned "trackers' : https://doc.tiki.org/Trackers Making a CRUD thing is very easy. Example: http://www.socius.be/Praktijkenbank or http://www.socius.be/Vacatures is all done with trackers. (that's the presentation side, the admin side works nicely with checks and workflows). Time to do the whole site was something like 2-3 months for 2 people. Good CRUD ability is what most people are looking for in web frameworks and we are a bit lagging here. In Python we get http://www.pythondiary.com/tutorials/simple-crud-app-django.html We need to get this working.
