Online IDE (via Gitpod)

Instead of installing Context Mapper in Eclipse or Visual Studio Code, you can use our Editor and tools directly in the browser! If your project is hosted on Github, you can use our VS Code extension inside the online IDE provided by Gitpod (based on Eclipse Theia).

You can easily find the Context Mapper extension in your Gitpod, as we publish it to the Open VSX Registry.

Getting Started

You can start a Gitpod online IDE for your Github repository by prepending to its URL. For example, if the Github repo URL is, you start the Gitpod with

Context Mapper Gitpod Demo

Start mapping your contexts using our demo repository right now: (you can also fork the repo first, in case you want to commit your own models)

Context Mapper Examples Repository

Our examples repository already contains a Gitpod configuration as well. Therefore, you can simply start the online IDE and the Context Mapper extension will already be installed.

Configure Own Repository

If you start the online IDE for your any other repository (not yet configured), you can easily install the Context Mapper extension.

In case you want to configure Gitpod for all users of your repository, click “Setup Project” after you started the IDE to setup a .gitpod.yml file:

Setup Gitpod Project (.gitpod.yml)

To install Context Mapper, just open the extensions view, search for “Context Mapper”, and click “Install”:

Install Context Mapper in Gitpod

In case you install the extension for the project (not only for user), it will be added to the .gitpod.yml file. By committing the file to your repo, you share the configuration with all users of your repository.

Configure Additional Tools

Depending on how you use Context Mapper you may want to install additional tools in your Gitpod. For example: for the graphical Context Map generator you need Graphviz being installed on the system. This can be achieved by configuring a custom Dockerfile for your Gitpod. Just add a .gitpod.Dockerfile file to your Github repository. Here an example with Graphviz as additional tool:

FROM gitpod/workspace-full

# Install Graphviz
RUN sudo apt-get update \
    && sudo apt-get -y install graphviz

In the .gitpod.yml file you have to declare the file as follows:

  file: .gitpod.Dockerfile
