Hey all! I've just updated my VSCode extension https://marketplace.visualstudio.com/items?itemName=forrcaho.chuck . I never realized that playing the file in the editor never worked under Windows; now it does. Syntax highlighting has been fixed to work with 1.5.x (I should make it clear, it's broken under older versions of chuck; I didn't see a great demand for backwards compatibility). That's something that also never worked under Windows, but now does. The syntax checking is turned off by default, because if you have multi-file projects you'll get syntax errors about things defined in a file meant to be included earlier with Machine.add at runtime. (I'm soliciting ideas about how to fix this!) Oh, yeah, I updated the syntax highlighting so Chugraph is recognized and Chubgraph no longer is. Please give it a spin, let me know if you have issues, and leave ratings/reviews on the VSCode Marketplace site if you like it.
