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

Moose on 1.2

by Laval Jannik

I make changes to load Moose on pharo 1.2 here is the script: ===== Gofer new squeaksource: 'rb'; package: 'AST-Core'; package: 'Refactoring-Core'; package: 'Refactoring-Changes'; package: 'Refactoring-Critics'; package: 'Refactoring-Environment'; package: 'Refactoring-Spelling'; load. (ConfigurationOfShout project version: '1.2') load. Gofer new squeaksource: 'Moose'; package: 'ConfigurationOfMoose'; load. (Smalltalk at: #ConfigurationOfMoose) perform: #loadDefault. ===== It loads, with some deprecation due to FileSystem. I have not the right to change that. But moose loads :) --- Jannik Laval

Re: could we have a fly by help with the syntax in the query pane?

The big problem now is linking the package organizer to system events, so that it updates itself whenever a package is added, renamed, removed, changed... So far this is not done in RPackage because the event were not there. But now they are available so we should check that. I will check and discuss that with cyrille because this will help us. > This was not done with PackageOrganizerCache because it's a bit difficult and because it was just a workaround at the time. Now RPackage should replace the current organizer and has to take care of such events. It also appear that RPackage initializes itself faster than PackageOrganizerCache (probably because it's more clever in its usage of PackageInfo API). I do not know.

disappearing menu

by Fabrizio Perin

Hi, i have a problem with the moose panel: when i load my stuff (MooseJEE) i have a group of database tables which has defined on top 2 visualizations. When i load a model form a MSE file, the first time that i click on that entity it is actually recognized has a TableGroup (see figure 1). When i click a second time on it it not consider anymore a TableGroup but just a MooseGroup, consequently i loose all the information specifically related with the table group (see figure 2). I define my group like this: mooseModel>>>allTables <navigation: 'All Data Base Tables'> | group | group := self allWithType: MJFAMIXTable ofGroupClass: MJFAMIXTablesGroup. group description: 'All Data Base Tables'. ^group SessionBeans group has the same definition but it works all the time. Any ideas on which could be the problem? Cheers, Fabrizio

Re: Class renaming in Moose Algos Graph

by Guillermo Schwarz

Hi Guys, Why don't you do something more focused on the long term and don't you change the Smalltalk compiler with namespaces? I don't think it should be that hard since each class already belongs to a category. Each category could instead be a dictionary from where the compiler could find classes that are mentioned in the class source. This has worked wonders in Java (classes inside packages). This way classes' names can be repeated ad eternum without generating collisions or otherwise polluting excessively the name space. So for example: FAMIXAssociation subclass: #FAMIXInvocation instanceVariableNames: 'sender receiver receiverSourceCode signature candidates' classVariableNames: '' poolDictionaries: '' category: 'Famix-Core' Would be instead: Association subclass: #Invocation instanceVariableNames: 'sender receiver receiverSourceCode signature candidates' classVariableNames: '' poolDictionaries: '' category: #FamixCore Then the category would be an index in the SystemDictionary: SystemDictionary at: #FamixCore put: Category new. (SystemDictionary at: #FamixCore) belongingClassList add: #Invocation "this should be done automatically by the subclass: method above" (SystemDictionary at: #FamixCore) referencedClassList add: ... "classes that are referenced by classes belonging to category #FamixCore" What do you think? Cheers, Guillermo.
