Presentation is an unfortunately named software package for creating human behavioral and neuroscientific experiments
This Visual Studio Code extension provides basic syntax highlighting and standard editing features (bracket closing, commenting, etc...) for the scripts used to create experiments in Presentation. These have the extension 'sce', 'pcl', or 'sdl'.
This should work for your day to day coding purposes. Highlighting seems to work well, but has only been moderately tested. The extension is relatively dumb: nothing fancy is done to handle different contexts (e.g. the SDL header and PCL program body).
