Hello, With nicolas we started to have a look at the eclipse-php-parser (provide with PDT), to export a famix-mse file from a PHP project. We already started to build an eclipse plugin that does some work: => We create an AST for each php file of the project => Then we have a visitor on this ast, and we are therfore able to make a specific action for each kind of node visited => For now, we just export some FAMIXNamespace, FAMIXClass, FAMIXMethods. So what's left is to implement each visit-method to extract informations for each node visited. For that we will have to know a bit more PHP :) Maybe the metamodel will have to be extended to take into account some PHP-specific elements, I don't know. If you want to have a look, sources are available via svn at: https://scm.gforge.inria.fr/svn/lse/Projects/Verveine Vervaine provide the extractor (not yet finished) for Java ans this one for PHP. Both are using a common mechanism to generate famix entities and extract them to mse. I will be on holidays until august and will probably no longer work on it until august. So if you want to have a look (and have the courage to install eclipse to read java code:)), have some suggestions, want to implement something, feel free to participate :)

Moose for SAS

by Ross Boylan

Some people suggested trying moose for analysis of SAS programs, and I'm trying to figure out where to start with the meta-modeling. SAS is not object oriented, though parts of it could be imagined to be. The main SAS code contains blocks of statements that begin with DATA or PROC; each block could probably be thought of as a function--to be precise, the application of a function. If I want to make some new models, where do I start? FM3? FAMIX? elsewhere? The 4.0 release announcement says FM3 and FAMIX3 are both implemented in Fame, so maybe start with Fame? I've read some documentation, but I can't tell. My inspiration for the project is understanding how some SAS datasets were produced. I have a system that creates numerous datasets, which feed into later datasets, etc. This is split at least across a couple of program files and it's really too complicated to keep in the brain. If I get ambitious it would also be useful to trace where particular variables came from, in the sense of both datasets and individual expressions. The only thing resembling a SAS parser I've run into (except for SAS, which is closed source) is a Perl module, and it looked relatively primitive. I've been using PetitParser, and at the point I started thinking about what it would parse results into. Thanks for any pointers. Ross Boylan

Petit SQL Parser

by Fabrizio Perin

Hi all, i did implement an SQL parser using Petit Parser. I toke the grammar specification from SQLite http://www.sqlite.org/lang.html . The grammar implemented is not complete, for now i did implement "just" the create table statement, it means that you should be able to parse at least a script for create the database. The code is in squeaksource http://www.squeaksource.com/@09zbthA-fDDfyUNQ/_OIex3aA . To download it you can evaluate this: Gofer new squeaksource: 'PetitSQLParser'; package: 'ConfigurationOfPetitSQLParser'; load. (Smalltalk at: #ConfigurationOfPetitSQLParser) perform: #loadDefault in the repository there are several packages: the core contains the parser for the grammar. In the package parser there is a parser that instantiate some draft objects representing relational elements. In the next future i will start to implement also other statements. If you start to use it and you have some problem please let me know. Cheers, Fabrizio

package restructuring

by Tudor Girba

Hi, I moved all code from Moose-MondrianScripts to Moose- MondrianPaintings, and I removed the Moose-MondrianScripts from the configuration. I would like to work slowly on package restructuring. In the following, I would like to rename the test packages: Moose-LAN -> Moose-TestResources-LAN Famix-LANTests -> Moose-Tests-SmalltalkImporter-LAN MooseKGB-TestFamix3 -> Moose-Tests-KGB Moose-KGB-* -> Moose-TestResources-KGB-* Moose-SmalltalkImporterTests -> Moose-Tests-SmalltalkImporter Moose-Test-PackageOne -> Moose-TestResources-Reference-PackageOne Moose-Test-PackageTwo -> Moose-TestResources-Reference-PackageTwo Cheers, Doru -- www.tudorgirba.com "There are no old things, there are only old ways of looking at them."

UML shape broken

by Fabrizio Perin

Hi, i just notice that the UML Class shape is broken, going back in the history seems that the problem has been introduced from the relative coordinates. This screen shot is from the commit Mondrian-tg.540 This from the commit Mondrian-Alexandre_Bergel.540 Than staring from the commit Mondrian-AlexandreBergel.545 the class name disappear i think covered by the rectangle containing the methods name that is bigger than before. The problem is in the method MOShapeSelector>>umlClass that has not been updated considering the last changes or in the changes themselves? Fabrizio

Distribution Map diff

by Mariano Martinez Peck

Hi. I am using Distribution Maps where I analyze an snapshot, a particular moment of my image state. I would like to be able to compare it with another moment. For example, I analyze packages and see which classes have instances for evaluating something. Something like this: ^ (self onContainers: (self listOfCorePackagesNames collect: [ :each | (PackageInfo named: each) ]) elements: #classes properties: [:element | element hasUsedInstances ] ) render open. Then, I do something different (suppose I start a seaside app) and I would like to see the difference between both distribution maps. To easily compare and know which "new" classes where used by running seaside that were not used in the first scenario. Maybe just a simple solution is to take both DM and to make a 3th with them: check each element...if in both it is the same...them I paint with a particular color. If they are different, each one keeps its original color. What do you think? is it doable? is there someting done about this? Thanks Mariano

MOFormsShape and MOChildrenShape

by Alexandre Bergel

Hi! I fixed a bug uncovered by Doru. Not easy to get this formsshape properly working. If you fix any bugs, let me know. Does anyone needs to nest a formsshape into another formsshape ? The following script does not work. -=-=-=-=-=-=-=-=-=-=-=-= | builder1 builder2 | builder1 := MOFormsBuilder new. builder1 row; fill; pref; grow; row; pref. builder1 column; pref. builder1 x: 1 y: 1 add: (MORectangleShape new text: [:each | each printString]). builder1 x: 1 y: 2 add: (MOChildrenShape new). builder2 := MOFormsBuilder new. builder2 row; fill; pref; grow; row; pref; row; pref. builder2 column; pref. builder2 x: 1 y: 1 add: (MORectangleShape new text: [:each | each printString]). builder2 x: 1 y: 2 add: (MOChildrenShape new). builder2 x: 1 y: 3 add: (builder1 asShape). view shape: builder2 asShape. view nodes: #(10 20 30 ) forEach: [:each | view nodes: (1 to: each )] -=-=-=-=-=-=-=-=-=-=-=-= But I first want to concentrate on the situation we need now. Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.
