Re: [Pharo-users] Can Pharo meet all your computing needs?

by Trygve Reenskaug

I don't think the current Smalltalk architecture can meet all your computing needs because security isn't part of its core and because it is inconceivable that all the necessary programs can be developed within its boundaries. Like several people I met at ESUG, my goal is the Dynabook and the Dynabook shall, by definition, meet all your needs. A Dynabook must be safe so that its owner is protected from hackers and other evildoers. The Dynabook SW architecture must be open so that owners can safely install functionality ('apps') that is available in a marketplace. (The i-pad with its hardware and its marketplace for apps is at the back of my mind.) I can only see one path from here to there. Start from e.g., Pharo and simplify it to create a Dynabook architecture with owner programming and with opening for safely adding functionality safely ad lib. (I suppose this is an ST based OS?)

Re: [Pharo-users] Phobos: Using open and save dialogs

by kmo

It's Ok I think I've got it. You can add a method like this to your main.js: function doFileOpen() { /* See: http://developer.mozilla.org/en/docs/XUL_Tutorial:Open_and_Save_Dialogs */ var nsIFilePicker = Components.interfaces.nsIFilePicker; var fp = Components.classes["@mozilla.org/filepicker;1"].createInstance(nsIFilePicker); fp.init(window, "Open File", nsIFilePicker.modeOpen); fp.appendFilters(nsIFilePicker.filterText | nsIFilePicker.filterAll); var res = fp.show(); if (res == nsIFilePicker.returnOK) { var thefile = fp.file; return(thefile.leafName); // --- do something with the file here --- } } Then call it from pharo with an evaluateJS method - if you return the filename from the javascript method pharo can pick it up: MyPhobosComponent>>getFilename |res| res:= self evaluateJS:'doFileOpen();'. Of course, you could build the entire javascript method as a string in pharo and call it using evaluteJS but it's simpler to put it into main.js as deaing with embedded quotes is fiddly. -- View this message in context: http://forum.world.st/Phobos-Using-open-and-save-dialogs-tp4774528p4774537.… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Phobos: Using open and save dialogs

by kmo

Does anyone know how you use the XULRunner /open/ and/ save/ dialogs from Phobos? I need to get a filename back from the user interface into the pharo/phobos image. -- View this message in context: http://forum.world.st/Phobos-Using-open-and-save-dialogs-tp4774528.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Excellent! I saw that yesterday and it can be a great engine to teach how to build web server. I will look at it after October because this looks really cool.

Run Pharo on top of Tiny Core linux total of about 50+ MB and you would have what you wish.. This can be more akin to Android on mobile if we all wish.. a complete ecosystem with multi VM pharo running on top of a stripped down modular linux. Pharo will be the UI / kind of riding on top of a thin WM.

Re: [Pharo-users] Can Pharo meet all your computing needs?

by kilon alios

I agree that reimplementing things in Pharo is a good solution, if that means a cleaner and more flexible design that brings more clarity to anyone viewing the code. Definetly Pharo promotes those things or else I would have little reason to keep using it. Yes agree , my solution is a temporary solution, more like a sensible compromise, but a compromise non the less. Having ideals and dreams is really important. "Flying" once sounded ridiculous and it was that crazy idea that brought us the airplanes, took a long time but it eventually happened. After all there is room to implement things and there is room to take advantage existing technology , both have a lot of benefits to offer to the user. On Sun, Aug 24, 2014 at 11:59 PM, Sean P.

Great tool to have. Definitely easier than doing everything in Zn or Seaside REST for getting something done quick. For hackathons, this is quite useful for sure! We should have a lineup of tools like that that allow us to shine during such events in order to promote Pharo. http://checkthis.com/hackathonbxl is one I go to in october. The monitor on the right is mine during a previous hackathon and what is on it is... Pharo ! (The guy on the picture was my team mate. He is a Scala guy). What would you think makes sense in such a stack beyond Teapot? MongoTalk, ZnEasy, Roassal, Mapless, ...
