Here is a class that can be of use for you then :-) Itâs a bit more complicated than what you need exactly, because I have lexical scoping and subscopes et cetera, but you can ignore that really. The relevant methods for you are generateNamedClass:withSuper: and compileBlock:forScope: Success! > On Mar 30, 2015, at 12:06, Werner Kassens <wkassens(a)libello.com> wrote: > > Hi Johan, > <g> you did surprise me! thanks for that info, i can use that indeed. > werner > > On 03/30/2015 04:47 PM, Johan Fabry wrote: >> Werner, let me surprise you: what I am doing is in the end exactly that! :-) ... > > ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD lab - Computer Science Department (DCC) - University of Chile

There is a mail Niall send me after I asked him for documentation Good luck ;) Merwan -------- Forwarded Message -------- Subject: Re: Glorp Documentation Date: Sun, 8 Feb 2015 18:18:13 +0000 From: Niall Ross (Cincom) <nross(a)cincom.com> Organization: Cincom To: Merwan Ouddane <merwanouddane(a)gmail.com> Dear Merwan, > I just wanted to know where can I find the glorp documentation you are > talking about here: > http://www.cincomsmalltalk.com/publicRepository/Glorp%28Bundle%29.html If you have a version of VisualWorks (or ObjectStudio) installed, then doc/GlorpGuide.pdf and preview/glorp/GlorpUserGuide0.3.pdf are paths from the root of installation. If you do not already have a version, you can download the Personal User Licence version and install it for free for non-commercial use, from http://www.cincomsmalltalk.com/ navigating from the PRODUCTS menu. Be aware the GlorpUserGuide0.3.pdf was never completed and is now very old, using some out-of-date protocol, etc. The GlorpGuide.pdf is much newer. You can also look at http://esug.org/data/ESUG2014/1%20monday/1400-1500-Glorp/GlorpTutorialGuide… which are the slides of a tutorial on Glorp that I gave at ESUG last year.

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 The two tutorials mentioned by Cameron are not too outdated yet to be useless, but The DescriptorSystem has learned quite a few tricks since the time those were written.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.

Of general educational nature are two Glorp guides that I know of: 1) Glorp / User Guide by Nevin Pratt, and 2) San Diego State University "Glorp Tutorial" by Roger Whitney. - Otherwise, there are members on this board who can direct your attention to test code to test your configuration.

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

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.
