Org.simantics.graph

Introduction

The org.simantics.graph feature provides a textual graph database source editing environment that integrates into the Eclipse IDE.

The feature adds a new project nature and builder for Java/Plug-in projects to support development of .pgraph partial graph source files. The environment will compile all partial graphs with in a project into a single transferable graph /graph.tg. Simantics applications will then be able to integrate this transferable graph into handled databases.

The environment also allows you to add the graph compilation nature to any project from the project's context menu Configure/Add graph compilation.

Plugins

org.simantics.graph.db

Importing transferable graphs to Simantics database and exporting fragments of the database as a transferable graph.

org.simantics.graph.compiler

1.1.6

Fixed URIs in Resource files (escape of whitespace)

1.1.5

Added extensions-field to tg format

Moved to trove3

Fixed bug in parsing range annotations in datatypes

Started complete validation of Layer0 definitions (added preference page for graph compiler)

1.1.4

Bugfixes

1.1.2

Added outline to graph editor

Added content assist to graph editor

• Content assists is opened with Ctrl-Space or writing '.'
• A proposal is selected with Enter or writing '.'

Added Open declaration (F3) action.

Optimized graph compilation time

1.0.8

Added support for annotations in data types (for example unit).

1.0.7

Supports loading literal data from external files (the file name given relative to the directory containing the graph file)

• @L0.loadBytes "filename"

• @L0.loadDataValue "filename"

Check for the number of template arguments

1.0.5

Changed endianness of transferable graphs.

1.0.3

Fix: When templates with literals were applied, the literal values were put to wrong resources.
