This a follow up of my previous post Conditional Uses Clause Considered Harmful, showing another real world use case of the technique described there.
Let’s assume we want to use FastMM with Full Debug Mode in a project to track down some errors in DEBUG mode. This requires us to include the FastMM4 unit as the first entry in the uses clause of the project DPR.
Now let’s also assume, we don’t want to use that FastMM unit in the RELEASE configuration – and – NO! – we don’t want to use an IFDEF inside the DPR, as the IDE tends to mess up with such things pretty often.
Using a unit alias like
solves this in a simple and elegant way.
