Sequence Configuration Language

A Visual Studio Code extension for the Sequence Configuration Language (SCL).

SCL is a configuration language designed to simplify automation of cross-application forensic and e-discovery workflows. It is designed to be powerful, containing most of the control flow features of programming languages, yet much easier to pick-up and use than traditional scripting or programming languages.

A quick introduction to the language and its features can be found in the documentation.

SCL can be validated and executed using the open-source command line application Sequence.

You can use connectors to automate workflows for popular data formats and forensic/ediscovery applications. It's also possible to automatically generate steps from any OpenAPI endpoint using the REST connector, or to build your own connectors for any application using the Core SDK.

Supported Features

Syntax highlighting
Hover
Code completion for step names and parameters
Error diagnostics
Run and validate sequences

This extension is still in preview. Please submit any bugs or feature requests in our GitLab repository.
