Can we batch-update or batch-convert classes to design properties or other?

0
I want to update a lot of legacy styling across multiple applications. We're talking about easily 200 classes per application. Luckily the class list is the same for each application and follow a similar naming pattern.   Going from basic needs to most favourable solution, would it be possible to Batch Add another class to an element that already has a specific class (e.g. "icon-solid-xyz" to "icon-solid-xyz solid-xyz")? Batch-rename classes based on a regex pattern (e.g. "icon-solid-xyz" > "solid-xyz")? Convert custom entered classes to design properties? Batch convert classes on certain widgets (e.g. buttons) to a specific icon from a specific icon collection?   Broad goal is to migrate to a new design system for icons, preferable without custom classes, and with only design properties and/or icon collections and doing so for many applications with the least amount of manual labour.    Request applies either to Mx9 or Mx10, whichever version holds a solution for the above goal

hi,


Mendix does not support bulk refactoring of CSS classes (add, rename via regex, or convert to design properties) in Studio Pro, in either Mendix 9 or 10. CSS classes are stored as free-text in page XML and there’s no refactor API.

What experienced teams do instead:

  • Use external scripts on page XML (regex search/replace) for large-scale, mechanical changes.
  • Add a SCSS compatibility layer to map legacy classes to the new design system.
  • Migrate to Design Properties / icon collections incrementally (manual or scripted XML edits).
