Not Pharo related - how does one respond to a message
by Daniel Roe May 25, 2015

May 25, 2015

Please allow me this one non-Pharo message. I am not that familiar with these message boards. When I see a message that I want to respond to how do I do that? I've been going to my email program - hotmail - and pasting in the subject line - copying and pasting any text that I want to include in my reply - writing a reply and then sending it. I can't believe that there's now a much more efficient way to do this. Enlighten me, please. Dan

PBE - Updated - section 2.10 System Browser
by Daniel Roe May 25, 2015

May 25, 2015

I am running Pharo 4.0, I think. I go to section 2.10 of the updated PBE (claimed to be for Pharo 4.0) which deals with The System Browser. I click on the background and get the World menu - I click on System Browser and get Nautilus instead of the System Browser (???). OK, so I search around and eventually find my way to printString. Two questions: 1) What is Nautilus - did I miss something here?, and 2) What are the shaded right facing triangles pointing to various menu entries trying to tell me? I tried to warn you - get ready for just a truck load of noobie questions. Dan

Garage and SQLite file databases, general project structure
by Torsten Bergmann May 25, 2015

May 25, 2015

Hi Guille, I had a short look at Garage [1]. Nice initiative! Looks like using a file is not supported for the SQLite3 backend in Garage: GADriver fromConnectionString: 'sqlite3://file://C:/temp/test.db' GADriver fromConnectionString: 'sqlite3://C:/temp/test.db' Maybe GASqlite3Driver>>fromConnectionString: could be adopted, but the conversion to a Zn URL already removes some stuff. (Ab)using the schema in the URL as a driverID is nice - but prevents the use of file:// schema. How can one construct a file db? Also I do not understand: while "Garage-Postgres" uses the Postgres project PostgresV2 as a backend the "Garage-Sqlite3" does not use NBSqlite3 or SQlite3 projects as backend. So "GASqlite3FFI" copies many methods of the original NBSQLite3 project from Pierce and myself and is therefore like an own fork now. Also the name FFI is misleading as it uses NativeBoost instead of FFI ... Also it would be good if the project would be layered, we could have a "Garage-Core" and "Garage-Tests-Core" with "Garage-Mysql" and "Garage-Tests-Mysql" for the fixtures. The idea is always to be able to load runtime code without tests for production code. Thanks Torsten [1] http://lists.pharo.org/pipermail/pharo-users_lists.pharo.org/2015-May/01919…

Is the Playground the Workspace?â
by Daniel Roe May 24, 2015

That little black arrow... Aha! Now I have learned something useful. I realize that the updating of Pharo is important but it would only be better if the documentation could be kept current as well. Thanks again... Dan

Is the Playground the Workspace?â
by Daniel Roe May 24, 2015

May 24, 2015

Question to Daniel: Did you try to know something about the tool before in the IDE? For example, did you try to read the About of the tool? (I'm trying to determine how useful/accesible are the help features of the tools) To show you what a noob I am - I don't even understand your question. Dan

Is the Playground the Workspace?
by Daniel Roe May 24, 2015

May 24, 2015

I am a complete noob when it comes to Smalltalk. I have chosen both Squeak and Pharo to learn this language. I am doing so just for my own knowledge and to try and keep my aging brain active. I may choose down the road to concentrate on one of the Smalltalk variants but right now I'm going to go with both. My question: All of the documentation refers to a Workspace. Sqeak has one but all I find in Pharo is the Playground. Does the Playground serve as the Pharo Workspace? Thanks for your time, Dan

Alt-tab between windows
by Avdi Grimm May 23, 2015

May 23, 2015

Hey folks! I've dabbled with smalltalk here and there over the years, but recently I've settled in to learn Pharo in earnest. A few of you might have seen the videos I've been putting up; they seem to be making the rounds on Twitter. I just want to say I've felt really welcomed by all the people who have commented with helpful tips, or offered to help with my exploration :-) I've run into my first big blocker as a newcomer. Like many programmers I'm a fan of keeping my hands on the keyboard. Now, I'm more flexible on this than some. I recognize that Pharo is a visual environment, and it makes sense to explore it with a mouse. And some interactions just make more sense with a mouse. That said, no matter what windowing environment I'm in, I find the ability to quickly cycle between windows without leaving the keyboard pretty crucial. One Windows or Ubuntu I would normally do this with Alt-Tab or Super-Tab. On MacOS it's Cmd-Tab. I've been trying to figure out how to do this in Pharo. I've looked for answers with Google, SO, and on IRC, and I've come up blank. I'm starting to think it can't be done. So, I've come here for your help. Is there a way to cycle between windows? Or is anyone working on it? Or, perhaps, am I missing an element of the Pharo programming workflow which renders it unneeded? Many thanks, -- Avdi

[OT] Pharo pi machine
by Torsten Bergmann May 23, 2015

May 23, 2015

Got my Raspberry Pi B+ with a TontecÂ® 3.5 touch screen display to bootstrap into Pharo. The Raspberry Pi from CI (https://ci.inria.fr/pharo/view/RaspberryPi/) worked out of the box on Raspbian. Nice!

Generate latex from Pharo
by Julien Delplanque May 22, 2015

May 22, 2015

Hi everyone, Is there any framework to generate latex code from Pharo? I would like to give a latex representation to some objects so I can export the latex code to a file I would include to my latex main file (for example). For example for a matrix I would like to do something like: fileStream nextPutAll: myMatrix asLatex. to have something like: \begin{pmatrix} 1& 2\\ 3& 4 \end{pmatrix} in the file. I used to do it with pylatex in Python and I wonder if something equivalent already exists in Pharo? Regards, Julien
