PRMorphInterface is a demo class and PRRenderingExamples contains some demo Pillar source code. Stephane, you wrote "Ideally we should add the pillar element to the associated morphic to manage back link from the renderer to the pillar tree. But this is to be done." I do not understand what you mean with this. It sound like there should there be a link from the morph used in rendering to the Pillar document object model node? The way how it is implemented at the moment is different. An instance of the class Text is created. parseButton action: [ document := PRPillarParser new parse: textInput text. morphWriter start: document. textResult text: morphWriter text ]. Then it seems that just a TextMorph is displayed writer text asMorph openInWindow. And what is the reason for this? --Hannes

Re: [Pharo-users] Morphic renderer for Pillar?

by H. Hirzel

The package contains two approaches to render a Pillar document object to Morphic. 1. PRVisitor subclass: #PRMorphWriter 2. PRDocumentWriter subclass: #PRMorphWriter2 The class comment for PRDocumentWriter says I'm the superclass of all classes supposed to output a pier document to a text file. I have a canvas to which the subclasses can write to using dedicated brushes. I have a configuration which specifies some details about how to write text (e.g., end of line convention). Class PRRenderer has examples for both approaches PRRenderer example "1" PRRenderer example3 "2 -- using PRMorphWriter2" "(example2 is not working)" I assume to use PRDocumentWriter subclass: #PRMorphWriter2 is the way forward and PRMorphWriter can be removed. --Hannes On 8/25/17, Stephane Ducasse <stepharo.self(a)gmail.com> wrote: > Feel free to enhance it. > It was fun to hack the visitor and to flesh the renderer on the fly. > > On Fri, Aug 25, 2017 at 3:48 PM, H.

It is always easier to start than to finish something. :) For the small core we are getting there as Guillermo work showed it to us. 70 is bootstrap from source. Do you believe it? It is real and tangible. People can do it on their own machine. And this is just the start. Now we have our roadmap it is available and we will work on that roadmap.

Re: [Pharo-users] [DesktopManager][Question] How do I jump to a particular desktop?

by H. Hirzel

Hello Torsten Thank you for the links to the DeskTopManager documentation. I know can use playgrounds with expressions like (Desktop manager desktops detect: [ :dt | dt name = 'Pillar Morphic Renderer']) useAsDesktop. and (Desktop manager desktops detect: [ :dt | dt name = 'PetitParser']) useAsDesktop. to quickly move to different desktops. In my intallation I added a utility method so that I can do Desktop manager switchToDesktopNamed: 'TeaLight' Kind regards Hannes [1] DeskTopManager>>switchToDesktopNamed: switchToDesktopNamed: aString (Desktop manager desktops detect: [ :dt | dt name = aString]) useAsDesktop.

Re: [Pharo-users] Loading and saving packages to filetree repos

by Peter UhnÃ¡k

Apart from the things I mentioned to you on discord (fileout through FileWriter, etc)... another idea came into my mind that could be possibly interesting. Every time a thing (Class, Method, ...) is created/changed/deleted, an event is announced in the system that you can watch for. (e.g. Nautilus uses this so when you add a method in one window, all Nautilus windows are updated). And then you do an immediate fileout of the changed item to the disk. a (hopefully still working) example: ``` ReflectiveWriter compile: 'methodChanged: aMethodAnnouncement | method dir | method := aMethodAnnouncement method. dir := FileLocator temp / ''outside-code'' / method methodClass name. dir ensureCreateDirectory. (dir / method selector) ensureDelete; writeStreamDo: [ :stream | "because line endings are #cr-azy by default" stream wantsLineEndConversion: true. stream << method sourceCode ]'. ``` I don't know how can Pharo watch for file changes in the system, but the opposite is also be doable in some manner. (and of course you could filter to write changes only when the change is in particular class, or particular package, or whatever). You would have to implement it yourself (extra time of coding, testing, debugging, ...), but in principle it should be doable within reasonable effort.

Re: [Pharo-users] [DesktopManager][Question] How do I jump to a particular desktop?

by Torsten Bergmann

Hi Hannes, Code is on http://smalltalkhub.com/#!/~TorstenBergmann/DesktopManager which points to this article: https://medium.com/@astares/multiple-desktops-for-pharo-5cbc46f3179f which should explain the details and that you can access the desktops using: Desktop manager desktops You can also click "CTRL+D" folowed again by another "CTRL+D" (DesktopManager -> Desktops") to have a custom spotter just for showing/switching the desktops. There is also CTRL + D followed by CTRL + AââââDesktop Addâ CTRL + D followed by CTRL + NââââDesktop Nextâ CTRL + D followed by CTRL + PââââDesktop Previousâ The only downside is that the global shortcut handler catches the "CTRL+D" for DesktopManager but also eats the same key event from the Playground which means the "do it" (which is also CTRL+D" is not working in a Playground anymore when DesktopManager is installed. Have not yet found a suitable solution for this. Contributions/fixes/ideas to solve this are very welcome. Thx T. > Gesendet: Freitag, 25. August 2017 um 14:56 Uhr > Von: "H.

[Ann][Pillar] Travis -> Bintray for PDFs

by Stephane Ducasse

Hi with Damien Pollet, we went over all the booklets and some of the Pharo books currently written in Pillar and made sure that each time you commit - a travis job is run - latex is produced as well as pdf - the pdf is stored on bintray - the release versions are stored on the github repo (I should verify) So now you can just do a PR and you get a super nice PDF. Have a look at Glorp or Voyage for example - https://github.com/SquareBracketAssociates/Booklet-Glorp - https://github.com/SquareBracketAssociates/Booklet-Voyage You can access the bintray files from the squarebracketassociates lovely binTray account :) https://bintray.com/squarebracketassociates/wip/download_file?file_path=voy… I'm writing a doc of the process so that other people can do it for their private projects.
