Welcome to the TOP TDL repository. We are transitioning to GitLab as the platform for collaboration under the ETSI Labs umbrella. We are still updating all links and documentation so please bear with us until the transition is completed. Let us know if there are some issues so we can address them promptly.
The TDL tools are available as a set of Eclipse plug-ins. You need to first be able to run Eclipse. The [Eclipse Modeling Tools](https://www.eclipse.org/downloads/packages/release/2020-06/r/eclipse-modeling-tools) distribution contains most of the necessary prerequisites for the TDL tools.
Once Eclipse is up and running, you need to add the [update site](https://tdl.etsi.org/eclipse/latest/) for the TDL tools:
After the update site is added, the list of plug-ins and features shall be shown in the installation dialog (menu item Help->Install New Software..). Select the desired features and proceed with the installation, which will require Eclipse to be restarted once the installation is finished.
Find more detailed information at [Installation wiki](https://labs.etsi.org/rep/top/ide/-/wikis/Installation).
Before any models can be created, you need to create a TDL project. In file menu select New and Project...
In the following page, locate the TDL Project and continue to complete the wizard. A file `model.tdl` is created which contains the basic structure of TDL model.
To create a new Generic **TDL diagram**:
* right click on the project and select Create Representation
* select the Generic TDL and on the next page select the root package in the model.tdl file
To create a new TDL model by means of the **TDLan2 textual representation**:
* right click on a project or a folder in the package explorer and select New -> File,
* type the filename ending with `.tdlan2` and
* the corresponding editor shall be automatically opened.
To create a new TDL model by means of the TDLan2 textual representation for **structured test objectives**:
* right click on a project or a folder in the package explorer and select New -> File,
* type the filename ending with `.tplan2` and
* the corresponding editor shall be automatically opened.
To translate a TDL model from the TDLan2 textual representation to the **XF format** (or the other way around) open the source model and press the <code>T</code> icon on the toolbar. The resulting model shall be stored in the same folder as the source model with the type of the model (`.tdlan2` or `.tdl`) appended to the name of the source model.
More information on using the plugins is available at [Usage wiki](https://labs.etsi.org/rep/top/ide/-/wikis/Usage).
## Setting up a local environment for development and testing
* Download and install Eclipse Modeling Tools package
* Install following additional components from Eclipse Marketplace
* Sirius
* Eclipse Xtext
* Epsilon
* Eclipse OCL
* Import the plug-ins in the Eclipse workspace
* Open the `tdl.genmodel`
* Right click on the top-node and generate model code
* Open the `GenerateTDLan2.mwe`
* Right click and select Run As -> MWE2 Workflow
* Additionally (or alternatively) repeat the same steps for the `GenerateTPLan2.mwe` (for editing structured test objectives)
* Additionally (or alternatively) repeat the same steps for the `GenerateData.mwe` (for the graphical viewer)
## Implementation of the TDL mapping to TTCN-3
The TDL mapping to TTCN-3 relies on some functionalities from [TRex2 / T3Tools](https://t3tools.informatik.uni-goettingen.de/trac). Before installing or developing the implementation of the TDL mapping to TTCN-3, the corresponding components need to be installed from the following update site:
https://t3tools.informatik.uni-goettingen.de/downloads/trex2/
After installation, to apply the transformation of a TDL model into TTCN-3 code, open the TDL model (making sure it is selected) and press the `T3` icon on the toolbar. This shall result in the generation of a `.ttcn3` file with the same name in the same folder as the model.
