ServerDirectory replacement

by Markus Fritsche

Hello, I'm revisiting some old code that I started to sort my favorites on my tv settop box. I noticed that ServerDirectory is gone. I naively replaced ServerDirectory by FTPClient, but I get an error that the iv stream is nil. So I looked at the comment of FTPClient - which recommends me to look at ServerDirectory. What is the proper way to log in to a ftp server, get a file and disconnect? getHD1File: aFilename | ftpClient byteString | ftpClient := FTPClient new. ftpClient host: 'coolstream'. ftpClient loginUser: 'neutrino' password: 'holycow'. byteString := ftpClient getFileNamed: aFilename . ftpClient quit. ^ byteString => MessageNotUnderstood: receiver of "sendCommand:" is nil Kind regards, Markus

Re: [Pharo-users] Theme : Choices : Good, but ...

Eeewww ugly Java GUI you got there First of all get Pharo 4 and select Dark theme, its really great. Second, now that I am close to finishing Ephestos 0.1 release I am preparing for working on 0.2 . In that release I will introduce Morpheas which will be a theme manager but somewhate diffirent to what we currently have. My goal is customised GUIs similar to the ones we see in Websites and Mobile phones, mainly flat design with some cool graphics. I would like to build simple API based on bitmap graphics and Athens for vector graphics that scale up and down. I would also like to approach another theme we see in web pages/ web apps the single page / window GUI. So that means I will have to customise the display of every pharo tool included starting from the core ones system browser and workspace and slowly working with other tools if alls goes well. Of course such a project will need years in development but I am willing to start very small , customising simple windows , probably workspace first since its the most basic one and work from there.

Once I tested it, not sure was Squeak or Pharo, running under the Console FrameBuffer. So your basic workstation can just be a Console only Linux (no X window).

Theme : Choices : Good, but ...

by Mayuresh Kathe

It's been close to 6 hours that I've been playing with the defaults offered with Pharo 3. Everything works so much more smoothly than Squeak! It also feels great. What's kind of problematic (as I see it) is the "look". There are 3 themes that I got with the default image; Pharo 3, Vistary and Watery. Look good, but somehow give off the feel of having more style than substance. I remember using something called Java Swing long back. It too had a plethora of themes, but the one that was the most detailed, and well designed (as in how well it worked), was something called "Java Steel". Please see the images at; http://docs.oracle.com/javase/tutorial/figures/uiswing/lookandfeel/OceanLAF… https://today.java.net/images/2004/02/laf_fig2.gif If there could be some way to have that look and feel, while adhering to the Java LaF Guidelines for the same, we might have a Pharo system which would be not only neater looking, but also lighter weight (by virtue of fewer extravagant graphical properties). Hope this suggestion isn't preposterous. :) ~Mayuresh

Sure is. You want to use OSProcess. Load OSProcess from the configuration browser. You can get environment variables like this: dirString:= OSProcess thisOSProcess environment at: #PRJ_DIR. Check this thread: http://comments.gmane.org/gmane.comp.lang.smalltalk.pharo.user/12496 Example: command := 'tac ', file fullName, ' | head -200'. output := ''. [ c := (PipeableOSProcess command: command). output := c output. ] ensure: [ c closePipes ]. Or check for all references for PipeableOSProcess, there are a ton. Do not forget the closePipes or you'll run out of resources at one point.

My ultimate goal (has been for a long time) is to build a low cost, computing system which can be as deeply programmable as possible. At the moment, my goal is to not only learn and start contributing back to Pharo, but also make progress in making it as reachable and accessible to learners as possible. For the same, I have been thinking along the lines of being able to bundle a Linux based Pharo system as a Rasberry Pi image. Well, that's all, I guess... :) ~Mayuresh On Fri, Sep 19, 2014 at 09:23:44AM -0700, Alexandre Bergel wrote: > Just wondering: what are your initial requirements that make you define this project? > > Cheers, > Alexandre > > > On Sep 19, 2014, at 9:18 AM, Mayuresh Kathe <mayuresh(a)kathe.in> wrote: > > > Hello, > > > > While I am still waiting for my copy of the PBE, I would like to > > initiate work on a project (along with friends). > > > > The idea is to build a minimalist Linux based system which would boot up > > straight into a full-screen Pharo environment. > > > > The system itself would be single user, consisting of not more than a > > Linux kernel, a few system utilities (busybox?), X (KDrive?) and Pharo > > (vm + image + ...). > > > > Would like to know if it's some how possible to control external > > programs from within Pharo, essentially shell scripts for network setup, > > etc. > > > > Thanks, > > > > ~Mayuresh > > > > > > -- > _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: > Alexandre Bergel http://www.bergel.eu > ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;. > > > >

Just wondering: what are your initial requirements that make you define this project?

Yes, it goes. I regularly give it to my student as an introduction to Pharo.

Re: [Pharo-users] Pharo by Example : Still usable?

by phil＠highoctane.be

Because there is a lot of content of value which isn't in the GitHub project yet. As I do have a ton of old Smalltalk books (hardcopy, Amazon is your friend) and a hardcopy of all Pharo books (including Pharo for the Enterprise, which is not out yet), I can tell you that, except on the "windows and widgets" front, almost all older books are still full of gems. Smalltalk with Style has been mentioned. Very good indeed. On thing about Smalltalk is that a lot of it is properly done and has been honed over time. So, an "old Smalltalk book" is not the typical door stopper kind of book in IT. (For the story, I've got two Java books which are under my monitors stands, never had any need to look at them since I've put them there. Not so with the Smalltalk books, from which I learn everyday). For blowing you mind, check Andres Valloud books. There is nothing like it elsewhere methinks. I tought I understood something about programming. Then I met Smalltalk. And I realized how little I knew. Pharo made me a better programmer. So much that I am now making a living out of Pharo exclusively. This thing makes you realize how much we have been slow on progress, and how current tools, no matter how great, are still stone age style tools. Being able to extend my own environment, shape it to my needs, well, that's a real "bicycle for the mind". The other tools are really "Anvils for the mind". I've been debugging Javascript in the latest Chrome, hell; the beast can't even locate the line I am stepping over properly (well known problem...). And I feel happy when doing Smalltalk. I can focus on the real problem. And not battling with all the damn paraphernalia that usually is with the other things (Maven anyone?) aRant stop.
