Formula Text Editor Window

[AnnabelleSwain]

Editing formulas in Revit is dreadful. It would be nice if there were an option to have a Text Editor window for larger formulas or all formulas. Basically, a mini MS Visual Studio or Sublime Text that reads Revit Syntax. It could color-code if something is a condition vs a parameter. Highlight errors, instead of vague pop-up windows, and autosuggest parameters and condition syntax. When you click on a parameter, it would highlight where it is used in the formula, or if possible, show where it is used in other formulas in a family file.

At the very least, I would love to have a multiline editor for formulas. I currently use MS Word to write long formulas and color-code them, but it is very time-consuming.

Can we have a python script editor option for editing family parameter formula? I think it would be helpful for more complex constrains.

It does look like something like this once existed as a plug-in, but it has since been discontinued. https://apps.autodesk.com/RVT/en/Detail/Index?id=8169385629859794630&appLang=en&os=Win64

It would also be beneficial to implement IntelliSense and other IDE-like features in parameter editor dialog boxes, enabling code completion based on the list of parameters available in the current Family Type window or Schedule Properties window. The plug-in example M.L.T.E. (https://apps.autodesk.com/RVT/en/Detail/Index?id=8169385629859794630&appLang=en&os=Win64), demonstrated by @Annabelle Swain, would also be useful for packing and unpacking string-like formulas into multi-line code with proper indentation. Summarizing the ideas above, it would be helpful to implement something similar to the concept illustrated in the picture I drew:

The idea is to simplify formula editing in the Schedule Properties dialog box by adding a new tab bar called Schedule Field Formulas, where users can view all fields (parameters) and formulas, and edit them using a specialized pre-processor. This pre-processor would convert string-like code into a multi-line format with proper indentation, and support IntelliSense along with other IDE-like features. A similar enhancement in the Family Types window within Family Editor mode would also be highly beneficial.
