Re: [Pharo-users] How to silently generate and remove code
A use case: the ability to test and debug the code generation part of SmaCC. SmaCC, when compiling a parser, generates dozens of classes and hundreds of methods, some of those very long, as a sequence of refactorings (and optimise them). Then SmaCC apply them all in one step. I'd dream of having a virtual environment where I could test-compile and check all those methods, via a system browser, before they are compiled.

Hi, Thanks for all the input. I've managed to download Glorp and the MySQL Glorp driver. However I'm having serious difficulties in setting it to work. I've search for some documentation in the Glorp page but seems there's a problem with Google Drive. Is there any place to search / look at an example on how to actually connect, map and query a SQL database from Pharo? Thanks in advance Nacho! - Nacho Smalltalker apprentice.

Werner, let me surprise you: what I am doing is in the end exactly that! :-) I am compiling blocks, written by the user of the system, that need references to variables that are outside the block, and they are shared between the different blocks. (The blocks have been written in a plain text textfield). So how do I have them access the variables? Here is the setup: - I generate a class (MyGeneratedClass) with as *class variables* all the variables that need to be accessed by the different blocks - For each block I generate a string with method source code (myGeneratedMethod_timestamp), whose body is: return the block - I compile the method and add it to MyGeneratedClass class (add it at class side) - I execute each method (MyGeneratedClass myGeneratedMethod_timestamp) , which gives me a BlockContext that has captured the variables. - sending value to that executes the block, and all blocks share the variables in MyGeneratedClass. Simple :-) And thanks to Marcus for discussing this with me a couple of years ago ... --- Save our in-boxes! http://emailcharter.org --- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD lab - Computer Science Department (DCC) - University of Chile

Re: [Pharo-users] MySQL framework for Pharo to analyze futures and options.
Hi, the most current documentation of (the most current) Glorp ships with VisualWorks. So your best bet is downloading their PUL product. The two tutorials mentioned by Cameron are not too outdated yet to be useless, but The DescriptorSystem has learned quite a few tricks since the time those were written. You need to ask your favorite search engine where to find them. I don't know of an official, still current place. Some other sprinkles of information can be found in several slide decks by Niall from ESUG 2013 and 2014. Very helpful once you've taken the first hurdle. I think, however, you can forget about Glorp.org as a source of information. It is painfully unmaintained at least it was when I last took a look. Sorry if I sound destructive. I use Glorp daily and like it very much. Niall and Instantiations are helpful in bug fixes and stuff it, but they sure cannot help in learning the basics.

Re: [Pharo-users] Uncommon keyboard shortcuts on Windows
Hi, there is currently ongoing discussion about shortcuts since there is a bit Ctrl vs Alt chaos in both Linux and Windows. Note for example that in many cases (undo, copy, paste, ...) you can use both ctrl and alt. Unfortunately there are many different tools (Nautilus, TextEditor, Rubic, Playground) and each specifies shortcuts by itself and slightly differently. In any case the default for Windows is at the moment Alt.

Hi Jan , (Under Windows...) For redoing ctrl+shif+z works fine on Workspace and Class Browser and in any other place i can remember. Copy, cut, paste, find, text selecting, moving to previous/next word (not exactly the same semantics) shortcuts convey Windows ones. Which other keyboard shortcuts, besides select-all, contradict Windows ones?
