README

Siemens SCL language support for Visual Studio Code. The syntax highlighting (and most snippets) work for other IEC 61131-3 StructuredText flavors as well. However, it has not been tailored to every flavor of ST.

Good alternatives to this extension if general ST support is required

This code is forked from gunders89's version.
