[ANN] OnScreenKeyboard
by Pavel Krivanek Nov. 24, 2014

Nov. 24, 2014

Hi, I created the first version of a virtual keyboard morph for Pharo. To try it, evaluate: Gofer it url: 'http://www.smalltalkhub.com/mc/PavelKrivanek/OnScreenKeyboard/main'; package: 'OnScreenKeyboard'; load. OnScreenKeyboard new open. Currently it doesn't work well together with completion morphs so please disable code completion. Features: - splitted int two parts - compact look - swipe up to write uppercase letter - swipe left to do backspace - swipe down to write special character - swipe right to write numbers and other special characters - swipe up right to press combination with ctrl (e.g. ctrl+p) - swipe down right to press combination with alt - press Kb button to move the keyboard up and down on the screen - press shift/alt/ctrl keys to hold them (e.g. for selecting text with cursor keys and shift) Feel free to send patches and improvements directly to the project repository :-) Cheers, -- Pavel

Listening for shift key pressed
by Aliaksei Syrel Nov. 24, 2014

Nov. 24, 2014

Hi, In our project we would like to trigger some actions when user presses down/up Shift button. But we didn't find how to do it. It seems that such keys as Shift, Capslock, Ctrl are event modifiers in Pharo, that apply on already existing events (in HandMorph>>generateKeyboardEvent: evtBuf). Do you have any ideas or maybe have experience concerning described problem? Thanks in advance. Cheers, Alex

Something strange with fileOut
by Hilaire Nov. 24, 2014

Nov. 24, 2014

Hi, We write code and comment in English, so only ascii characters are used. For string we also use English, and when translation is needed we use catalog of messages as gettext, where the non ascii strings are externally represented. So most of the time we only use ascii characters in our code. However, if a developer writes non ascii character in a method, fileout may just break. The problem is described and related to MultiByteFileStream: https://pharo.fogbugz.com/f/cases/14462 I check with Squeak4.5, although I cannot enter non-ascii character (but that's another problem, probably related to the VM I am using not suited to Squeak) I have no error when fileout the same class with non-ascii character in method body. The MultiByteFileStream seems quite different, I don't know the history of changes in these two method versions but changed in Squeak version seems a bit newer. The changes may not be trivial because it involves the whole class hierarchy. Hilaire -- Dr. Geo - http://drgeo.eu iStoa - http://istoa.drgeo.eu

[ANN] Nireas - a theme manager for Pharo 4
by kilon alios Nov. 23, 2014

Nov. 23, 2014

Hello pharoers , I would like to present to you my latest project and a good excuse to learn Spec. First I would like to thank Nicolai for his help and all other people who helped me out understand Spec. Of course I am still learning :) So , Nireas is a theme manager for Pharo 4. What this means is that Nireas takes the dark theme and by presenting you with an easy to use gui allows you to change the colors on the fly to adjust the theme to your own preferences and habits. This is an example https://www.dropbox.com/s/w3c72lz0r81v4iv/Screenshot%202014-11-23%2013.53.0… you can see the Nireas GUI on the bottom, the Nautilus on the left has the default dark theme colors, the one on the right has the color selected by Nireas. You can find instructions on how to install Nireas and how to use here https://github.com/kilon/Nireas Unfortunately the last one the scroll bar color seems to have no effect, I will have to look into it, but the other options work fine. Please note also that you will have refresh issues so its advisable to close existing windows and reopen them so they update properly to the new colors. Please try this tool inside a new fresh pharo 4 image, this code is very experimental and has been known to crash Morphic. So use with caution. Nireas implements its own theme subclassing the dark theme, the big diffirence here is that it defines color to be independent and dynamic so the theme can be , well, .... themable :D Nireas does not change anything inside Pharo so it can be installed safely. I would like to take this tool further to allow of course deeper customisations that goes beyond just customising colors, meaning change the look and feel of Pharo. But this means unfortunately/fortunately that some things will have to change inside Pharo and Pharo will have to become much more dynamic GUI wise to make dynamic themes much easier to implement. Nireas is part of my Ephestos project, so this is why it appears inside an Ephestos menu and hopefully I will keep working it as customising Pharo GUI is something that I find really interesting and fun, As always comments, insults, worship and rage is more than welcomed.

Dear all, we are to happy to announce SciSmalltalk v0.16 SciSmalltalk is a Smalltalk project, similar to existing scientific libraries like NumPy, SciPy for Python or SciRuby for Ruby. SciSmalltalk already provide the following basic functionalities: - complex and quaternions extensions, - random number generators, - fuzzy algorithms, - Didier Besset's numerical methods, - Ordinary Differential Equation (ODE) Solver. Version 0.16 includes updates from Werner Kassens to several packages, the work Nicolas Cellier about arbitrary precision floats. SciSmalltalk project web page is here: https://github.com/SergeStinckwich/SciSmalltalk All the code is available under the MIT licence. We have more than 563 green unit tests and we run a CI job here: https://ci.inria.fr/pharo-contribution/job/SciSmalltalk/ This version should work on Pharo 3.0/4.0 and also Squeak 4.5 (to be confirmed). We are looking for more code contributions and also tests, documentation !
