Note
⚠️ For all the above operating systems and installation methods, if you want to use KCL Python plug-in, you need to ensure that Python 3.7+ is installed and add the python3 command to your PATH environment variable.
To avoid the GLIBC version being too low, for lower versions of Linux such as Centos7, you can visit Github to find the release of kclvm-centos and download and install it.
2. Install the KCL VS Code Extension
To improve the KCL development on VS Code, there are VS Code extensions for both VS Code Web IDE and VS Code.
The VS Code Web IDE can be reached through the browser, and you can search and install the KCL for vscode.dev in the VS Code Extension tab. And here's the syntax highlighting view you'll get:
The KCL extension for the local VS Code IDE provides more rich language support for the KCL language such as highlighting, auto-completion, quick info hover and code navigation, etc. Although the extension is not a must-required part of KCL, it is recommended to install it to improve coding efficiency.
