Adds syntax highlighting, semantic (error) highlighting, and local execution for the HL7 Clinical Quality Language (CQL) to VS Code
The cqframework.cql extension has been published to the VS Code Marketplace, so the installation is simple. Just search for "Clinical Quality Language" in the marketplace and install the extension. It'll be activated once you open a .cql file.
This extension requires Java to be installed. It'll prompt you to install Java if required.
This project maintains a User Guide that provides detailed instructions on how to use the plugin to author and test CQL content.
The Clinical Quality Language (CQL) is a domain specific language for expressing electronic clinical quality measures (eCQM) and clinical decision support rules (CDS) in an author-friendly computable format. Find out more about CQL:
- CQL Specification
- CQL Stream on FHIR Zulip Chat
- clinical_quality_language on GitHub
- Clinical Quality Language at HL7
- Clinical Quality Framework (CQF)
Bugs and feature requests can be filed with Github Issues.
The implementers are active on the official FHIR Zulip chat for CQL.

Install npm
Run npm install from the root
Run npm run watch from the root
Run the debug launch from VS Code
TIP: The cql-language-server that provides error highlighting is a Java project. It's also launched in debug mode when this VS Code extension is launched in debug mode, allowing you to attach a Java debugger as well. If you're simultaneously iterating on the cql-language-server, you can create a symlink to that Java artifact and changes will be picked up when VS Code restarts.
On linux:
vscode-cql/dist/jars$ ln -s your-repo-home/cql-language-server/ls/service/target/cql-ls-service-1.5.8.jar cql-ls-service-1.5.8.jar
Set your repo home directory and update the versions as needed.
This project follows the guidance given by Microsoft for the VS Code marketplace here and publishes prereleases to the VS Code marketplace using odd minor version numbers. Full releases are published using even minor version numbers.
This plugin is a reimplementation of much of the functionality in the atom_cql_support plugin for the Atom editor. Additionally, the Red Hat vscode-java plugin was referenced extensively in developing this plugin.
