Make the API easy?
- Copy on Write to avoid copies at runtime
- Can we do it at compile time?
- Let tools get const and references right
- Warn about unnecessary copies
- Clang can help here
Notes
- need real examples
- QtCreator supports only very basic refactoring tools
- having tools outside of QtCreator and use these tools maybe inside
- API changes need to be available by Clangtidy scripts (?)
- what about templates?
- concept
- the tools cannot fit to all cases
- this kind of tools can help to move to Qt 6(or other future versions)
Make changes easy
- API changes are expensive
- API looks outdated if not adapted to current paradigms (legacy code)
- How can we make them easy
- How can Clang help here
Clang Query
- Think about it as SQL for the AST
- Makes big changes much cheaper and secure
Immediate feedback vs overnight refactoring
- Both are important
- Immediate feedback reduces refactorings and reviews
- Run refactorings overnight for expansive refactorings
- Integration with the CI
