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.

I have been reflecting on this point a bit. I think there are two relevant classes of newbies here. One is people who are learning to be Pharo hackers and joining this community. They need to "get with the program" and learn to do things the same way as everybody else. So they need to learn Smalltalk, Monticello, Metacello, Iceberg, FogBugz, etc. The other is people who are using a Pharo-based application and want to make an extension. For example, imagine a Dr. Geo user who wants to contribute support for a new geometric function that they need for their work. This person needs to take the shortest path to solving their problem: reuse their existing skills (e.g. command-line git) and make use of examples (e.g. copy-paste-tweak some existing code.) I'm concerned about the latter group. I'm building an application that I want users to be able to extend, and I am assuming that most of them are not aspiring Smalltalk hackers (yet.) So I am wondering how to minimize the barriers to entry for people to contribute their first extension. My model is Emacs. Lots of people use Emacs to edit text files. Many of them become power users by copy-paste-tweak from each others' configuration files. Only a few take the next step and learn Lisp e.g. to understand what "lambda" actually means.

Re: [Pharo-users] Pharo 6.0 and 6.1 64 bit freeze on MacMini

by Tim Mackinnon

I don't think it's just on Mac Mini - my MacBook Pro late 13" 2016 retina will show similar symptoms if I try and resize the window to full screen (not the maximise button, but try and drag the bottom corner of the world to the last 5-10 pixels at the bottom of the screen). I think Ted noticed similar in that it looks frozen but it's actually the screen not redrawing as you can fiddle to get it back (can't recall what I did - maybe drag a window on top?)

Hi John, â¦ thanks. another wild, wild guess: it could then perhaps be, (if Pharo uses Open GL) that my graphics card has Open GL incompatibility? or that Pharo 6.1 uses Open GL calls not implemented on an Intel HD Graphics 4000 chip as in my mac mini? kind regards TedvG > On 25.
