I’m using: SWI-Prolog version 8.1.9 on Windows 8.1.

My editor of choice for editing Prolog source is Notepad++. Does anyone know if there is a plug-in that will give you the same functionality some of the commercial code editors do? For example, when editing Javascript with JetBrain’s WebStorm IDE, after I type the open paren for a function name, an overlay window shows me the parameter list for the function and the help text for that parameter. As I move through the parameters, the window updates to show me the help info for the current parameter.

Is there anything like this for Prolog and Notepad++?

If not, has anyone come up with a trick or tip to emulate this? My app has gotten fairly large now and I find myself frequently jumping between predicates and the predicates that call them to remember the parameter names for the callee function.

The extension [VSC-Prolog](https://marketplace.visualstudio.com/items?itemName=arthurwang.vsc-prolog) to [Visual Studio Code](https://code.visualstudio.com/) has these features and I do use the extension daily, but the features you seek do not currently work with my install. Maybe it is just me not using it correctly but have a look, you may get it to work.

EDIT

Just did the monthly upgrade of VSC and now it is working.

Thanks Eric. Are you running VSCode on Windows or Linux, would you mind giving me your O/S version that you’re running VS Code on?
