A List of Refactoring Projects

See Development Project Ideas and Funded Project Ideas for more possible projects.

See Refactoring plan for guidelines on how to refactor.

Attention: Some of these suggestions might not make sense or have better solutions. For example instead of moving some unused function to a different file, you should remove it. Apply the principles of adding unit tests and adding documentation (doxygen comments).

Little Projects

  • Derive SPStar from SPShape (not SPPolygon), update 'object/README'.
  • Move sp-item-transform.h functions into SPItem. See: https://gitlab.com/inkscape/inkscape/-/merge_requests/2976
  • Move sp-item-update-cns.h function into SPItem. Removed
  • Move sp-item-rm-unsatisfied-cns.h function into SPItem. Removed
  • Remove config.h code (or document why it is needed). DOCUMENT/Autogenerated
  • Remove macros.h (or document why it is needed). Removed
  • Remove dependence on Glib::object in ResourceManager().
  • Simplify ResourceManager... it does only one thing: fix broken links. Replaced
  • In SPObject one can write:
   getRepr()->setAttribute("x", "y");

or

   setKeyValue( sp_attribute_lookup("x"), "y");

These are redundant and neither is really convenient. SPObject perhaps should have it's own setAttribute() function.

  • Rename helper-fns.h with a better discriptive name and move to util(?). MOVE/RENAME
  • Remove dependence on object-set.h in files in src/livarot directory.
  • Evaluate all the functions in io/sys.h/.cpp. See if we can't use standard glib functions.
