# A VSCode extension for a textual DSL with diagrams

![Screenshot](images/screenshot.png)

Features
* a textual DSL editor based on an Xtext LSP,
* diagrams based on Sprotty,
* animated automatic diagram updates on text changes,
* synchronized selection of text editor and diagram,
* SVG export (ALT-E), animated center selection (ALT-C), animated fit selection to screen (ALT-F).

## Build it

```bash
language-server/gradlew -p language-server build  # build the language server
yarn --cwd webview                                # build the bundle.js for the webview
yarn --cwd extension                              # build the extension
```

## Run it
* load the repo into VS Code,
* built it, and
* lanch the extension _states-extension_.

An example DSL file can be found [here](https://raw.githubusercontent.com/TypeFox/theia-xtext-sprotty-example/master/ws-theia/MrsGrantsSecretCompartment.sm).

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.

GitHub Actions: GitHub context variable exported as environment variable

A GitHub context variable (such as issue title, PR description, or comment body) is being passed back as an output. These context values are user-controlled and could be exploited by consuming workflows.

GitHub Actions: GitHub context variable passed back as output

A GitHub context variable (such as issue title, PR description, or comment body) flows into a dangerous sink (such as shell command execution). This is a critical security issue that could allow command injection or code execution attacks.

GitHub Actions: GitHub context variable flows to dangerous sink

An environment variable flows into a dangerous sink (such as shell command execution). If this environment variable comes from an untrusted source, it could be exploited to inject commands.
