[Pharo-project] Issue 2451: Make Algernon work in Pharo 1.1
by Guillermo Polito June 7, 2010

June 7, 2010

Hi, i was looking at this issue and I have some questions :): - There are some changes to HandMorph in a changeset hardcoded in the ConfigurationOfAlgernon. As Mariano said here ( http://forum.world.st/Putting-Algernon-and-WorkingSet-in-a-Dev-image-td1295…) "The main change does the simples modifications to HandMorph for it to support various focus holders". Is it safe to integrate it in Pharo? If so, should it be integrated in the core Morph package? The changeset is the following: * '''From Squeak3.7gamma of ''''17 July 2004'''' [latest update: #5985] on 9 August 2004 at 7:56:10 pm''!

[Pharo-project] SmalltalkImage vs SystemDictionary
by GermÃ¡n Leiva June 7, 2010

June 7, 2010

Hi, I have a doubt ... why in Pharo 1.0 Smalltalk class == SystemDictionary and in Pharo 1.1 Smalltalk class == SmalltalkImage? Looking at the issue tracker (thanks Carla): We should make - Smalltalk pointing to SmalltalkImage current - have SystemDictionary only having classbindings management. and Smalltalk globals pointing to SystemDictionary instance. This way we finish the refactoring started long time ago. We should have a look at the way this was done in Squeak so that we get the same compatible for now solution. What's involved in *the refactoring started long time ago* and what's the motivation for it? Cheers -- GermÃ¡n Leiva LeivaGerman(a)gmail.com

[Pharo-project] Keyboard Shortcuts in Pharo?
by Bart Gauquie June 7, 2010

June 7, 2010

Dear all, On my job I'm using Java; and Eclipse as an IDE. I'm discovering Pharo since a year now. I find it in almost every way superior. But not on the following way. I use keyboard shortcuts heavily in Eclipse. I use them to quickly select parts of code, extract methods, rename methods, fields, classes, switch browsing windows, delete a line of code, copy and move lines of code. I tend to miss these shortcuts in Pharo. There are actually a lot of shortcuts (http://news.squeak.org/2007/01/26/looking-for-a-shortcut/ - Andreas comment). But I still find that I have to leave the keyboard way to often and use the mouse to navigate to another window / or part of the browser I'm working in. Let me explain that a bit further. I will try to give some examples of behaviour I'm missing in Pharo. - If I'm editing a class and working in the source view. I'm done, I want to run the tests again I just ran. I have to take the mouse, navigate to the class and hit Alt-t. Or use the test runner. In Eclipse there is a global shortcut Alt-F11 which just runs the test (or even better: the suite of tests) which ran previously. It moreover runs it in the background and if everything is still ok, does not bother you again. It only pops up if something broke. This behaviour is very handy if you're refactoring. You can then with every small change run all relevant tests in matter seconds and continue. - If I'm editing in the source pane. I'm done editing, and I want to navigate for instance to another method. I have to take the mouse to navigate to the methods, scroll and click on the new method. Again had to take the mouse. In Eclipse, there is a Ctrl-O shortcut which brings up a list of all methods in this class. At the top there is an input field in which I can start typing; while typing the list is restricted. I can then using the arrow keys navigate to the method and hit Enter, and I'm in the method. - For switching between browser windows Eclipse also does have a handy mechanism. Eclipse keeps in memory a list of files you're editing ordered by latests usage. I can then quickly navigate through the list by hitting Ctrl-F6. Just hitting Ctrl-F6 navigates to the previous window visited. Hitting it again gets back. If you however hit Ctrl - F6, keep the Ctrl pressed in, and hit F6 again, you navigate the the second last window edited. I use this behaviour constantly to navigate back and forth between the test you're writing and the implementation. - Eclipse also has very keyboard shortcut integration to select/delete parts of the code. Ctrl D deletes the current line. Alt arrow up / down moves the current line (or selection) up or down (while keeping the clipboard selection). Alt-Shift-arrow up/down copies the current line (or selection) up or down (while keeping the clipboard selection). Alt Shift Left arrow / right arrow does a nifty code selection: if the code compiles properly, it will with every next hit on left arrow select a larger block of code. So if my cursor is on a message send, it will first select the message send, next the receiver and the message send, next: if this was a nested, select the part out of that, and so forth. This is very handy if you for instance want to do a extract method refactoring on some part of the code. Just quickly select it using this Alt-Shift selection and extract it. - Which brings me to the refactoring shortcuts, which I'm missing the most. * The most important one is rename. In Eclipse if I select a field, a temporary var, a message, a class, anything that can be renamed; I can always hit Alt-Shift-R to rename it. I don't have to go into a menu, refactor class, or refactor method, or refactor source with the mouse to select rename. Just click on it, hit the shortcut, type the new name and hit Enter. * The next one is Extract Method. After quickly selecting I just hit Alt-Shift-M, give a name (Eclipse guesses a name) and I extract. * Another very useful one is Extract Local Variable using Alt Shift L. I'm very well aware of the fact that in Smalltalk you typically only need half of the lines of code to achieve the same, but still I'm missing this kind of behaviour to quickly navigate, adapt code, run tests, ... All the tools are there in Pharo, but I just feel that they need a little better keyboard integration. How are experienced Smalltalkers feeling about this? Are there any solutions available already that I haven't found ? If not, I'm more than happy to implement some of these, but my knowledge of Morphic is still rather limited. Can anyone provide me with some pointers how to achieve that? Kind Regards, Bart -- imagination is more important than knowledge - Albert Einstein Logic will get you from A to B.

[Pharo-project] Changes aren't saved in the default (unnamed) changeset on a new image
by Guillermo Polito June 7, 2010

June 7, 2010

Hi! I'm using the develop Pharo-1.1-11367-Beta on windows. When I make a change with a fresh image, that change isn't saved in the default changeset :(. In the Core image it's just ok. Is it a bug or a 'feature'? Cheers, Guille
