famixngsql's Introduction

FAMIXNGSQL

A meta-model for SQL databases using FAMIXNG with its generator.

Install

In a Pharo 7.0 image, open a playground and execute the following script:

Metacello new
  repository: 'github://juliendelplanque/FAMIXNGSQL/src';
  baseline: 'FAMIXNGSQL';
  load

Developing the meta-model generator

This section presents some tips and tricks that help in the development of the meta-model.

Modifying the meta-model generator

If you modified the generator and want to re-generate the meta-model, you have to:

Ensure that no more instances of the meta-model exist in the system.
Run FmxSQLMetamodelGenerator generate.

famixngsql's Issues

Many objects are moved from FamixNGSQL-Importer to FamixNGSQL after model generation

tWithSourceAnchor seems changed direction

logCr => Transcript show: 'something' ; cr

FamixMetamodelGeneratorUnknownTrait: Trait TArgument not found in the metamodel. Please add it or refer to a submetamodel.

defineStructuralReferencesHierarchy
	reference --|> association.
	reference --|> #TArgument.
	tableReference --|> reference.
	columnReference --|> reference.
	typeReference --|> reference.
	namespaceReference --|> reference

If we make ivar tArgument, then it will work

Entity is deprecated, association is gone

Base class FamixBasicInfrastructureGeneratorin Pharo 7

defineClasses
	super defineClasses.
	entity := builder newClassNamed: #Entity.
	sourceAnchor := builder newClassNamed: #SourceAnchor.
	sourceLanguage := builder newClassNamed: #SourceLanguage.
	unknownSourceLanguage := builder
		newClassNamed: #UnknownSourceLanguage.
	sourcedEntity := builder newClassNamed: #SourcedEntity.
	association := builder newClassNamed: #Association.

defineHierarchy
	sourceAnchor --|> entity.
	sourceAnchor --|> #TSourceAnchor.
	sourceLanguage --|> entity.
	sourceLanguage --|> #TSourceLanguage.
	sourcedEntity --|> entity.
	sourcedEntity --|> #TSourceEntity.
	sourcedEntity --|> #TWithComments.
	association --|> sourcedEntity.
	association --|> #TAssociation.

in Pharo 10:

FamixMetamodelGenerator << #FamixBasicInfrastructureGenerator
	slots: {
			 #entity => FamixDeprecatedSlot message: 'This variable should not be used anymore. XXXEntity is now the default root and you don''t need to declare you inherit from it. If you wish to add property to it, get the class with `self ensureClassNamed: #Entity`.' .

FmxSQLStructuralMetamodelGenerator defineStructuralHierarchy - fix namespace

FamixTWithSourceAnchor is deprecated, migration required

Before:

Trait << #FamixTWithSourceAnchor
	slots: { #sourceAnchor => FMOne type: #FamixTSourceAnchor opposite: #element };
	package: 'Famix-Deprecated'

Now

Trait << #FamixTSourceAnchor
	slots: { #element => FMOne type: #FamixTSourceEntity opposite: #sourceAnchor };
	tag: 'SourceAnchor';
	package: 'Famix-Traits'

It seems that direction of relation was changed, so we should not simply rename the class...

Fix Namespace

We have

entityInNamespaceComment
	^ 'I am a trait that any entity which can be part of a namespace use.'

but no traces of entityInNamespace trait.

FmxSQLMooseModel initialize changed

initialize
		<generated>
		super initialize.
		self metamodel: (self class environment at: #FmxSQLMetamodelGenerator) metamodel

Now:

initialize

	<generated>
	super initialize.
	self metamodel: FmxSQLModel metamodel
