Typedef Editor

Is your feature request related to a problem? Please describe. I’m always frustrated when I need to change the base DataType for a TypeDef and can’t readily do so.

Describe the solution you’d like An editor window to edit the TypeDef like there is for composites and function signatures.

Describe alternatives you’ve considered Opening the python interpreter, creating a new TypeDefDataType to the new base type and using DataType.replaceWith. This gets old pretty quick.

@ghidra1 if I understand correctly, DataTypeManager.replaceDataType will iterate over all datatypes, find which ones contain said typedef and replace the usage of the old typedef with the new one? I most certainly don’t want to iterate over a few million types which are using a poorly typed uint64_t that ended up 4 bytes and replace each uint64_t with a new one. It is much better to correct the existing uint64_t and make only one change.

I really do hate to be like this, and I would never share it, but if the replaceWith method is removed my next approach would be to write a script to alter the DatabaseObject directly and swap the underlying type. (Don’t try that at home kids, I’m a professional. A professional idiot maybe, but a professional nonetheless)

The case with poorly typed fixed size integers is really the only consistent use case for modifying a typedef. That being said it does make sense for them to be immutable; it’s just really painful for the edge cases where you need it to be mutable.
