Issue 492 in moose-technology: Glamour browsers do not release all subscriptions to announcer objects

by moose-technology＠googlecode.com

Status: New Owner: tudor.gi...(a)gmail.com Labels: Type-Defect Priority-High Component-Glamour Milestone-4.3 New issue 492 by tudor.gi...(a)gmail.com: Glamour browsers do not release all subscriptions to announcer objects http://code.google.com/p/moose-technology/issues/detail?id=492 I noticed that in some complex updating between panels, using an external announcer, some of the update subscriptions were not removed when the browser is closed. I debugged a little and I founded that this implementation: GLMUpdateAction>>unregisterFromAllAnnouncements announcerObjects ifNotNil: [ announcerObjects do: [:each | each unsubscribe: self ] ] is bugged, because if announcerObjects are not previously computed (and in some cases that's what happens), the subscription is not removed. This implementation (just using the accessor instead the direct object), solves the problem (but I don't know is it's a right fix, and it should be a fix in other place) GLMUpdateAction>>unregisterFromAllAnnouncements self announcerObjects ifNotNil: [ :objects | objects do: [:each | each unsubscribe: self ] ] Cheers, Esteban

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

Issue 494 in moose-technology: Dynamic presentation should be a browser

by moose-technology＠googlecode.com

Status: New Owner: ---- Labels: Type-Enhancement Priority-Medium Component-Glamour Milestone-4.3 New issue 494 by tudor.gi...(a)gmail.com: Dynamic presentation should be a browser http://code.google.com/p/moose-technology/issues/detail?id=494 The problem is that when in a presentation we ask for entity, we get the value of the entity of the pane around the dynamic presentation, instead of the transformed value.

Issue 510 in moose-technology: Introduce Port>>transientValue:

by moose-technology＠googlecode.com

Status: New Owner: ---- Labels: Type-Enhancement Priority-Medium Component-Glamour New issue 510 by tudor.gi...(a)gmail.com: Introduce Port>>transientValue: http://code.google.com/p/moose-technology/issues/detail?id=510 We should be able to set the value of a port only temporarily. This would be useful for triggering other transmissions. For example, to implement a search like behavior we could use the code from below. The problem is that if you press the search icon once, then change the selection manually, and then press the button again, the selection will not change because the #focusOne port did not change the value. |browser | browser := GLMTabulator new. browser act: [:b | (b pane port: #focusOne) value: 3 ] icon: MooseIcons mooseSearch entitled: 'Search'. browser column: #one; column: #two. browser transmit to: #one; andShow: [ :a | a tree display: [:x | 1 to: x]]. browser transmit to: #two; from: #one; andShow: [ :a | a tree display: [:x | 1 to: x*2]]. browser transmit to: #one port: #selection; fromOutsidePort: #focusOne. browser openOn: 3

Issue 540 in moose-technology: Glamour: removing dependency in configuration - core group

by moose-technology＠googlecode.com

Status: New Owner: ---- Labels: Type-Defect Priority-Medium New issue 540 by vuqui...(a)vub.ac.be: Glamour: removing dependency in configuration - core group http://code.google.com/p/moose-technology/issues/detail?id=540 In the configuration of Glamour, the core group was loading only Glamour packages, and the extras group: mondrian and magritte presentations. This allowed to load those presentations if needed. Currently, the core group is also depending on Mondrian. The method MOViewRenderer>>openWithStatusbar is causing this dependency in the package Glamour-Scripting. Can this dependency be removed from the group core? * Type-Enhancement * Component-Glamour
