Preprocessor

[Uffe Kousgaard 0]

Is it possible to have the compiler output the source code as it looks after ifdef's etc. have been applied?

 

Our problem is our source code is also sent to the Oxygene compiler and after a change, it no longer handles Delphi compatible ifdef's.

If we can send it preprocessed code, the problem would be solved.

 

If anyone happens to know if it is possible with freepascal compiler, it would also be great.

Isn't "Oxygene" only sold with support? I thought so. If there is a "free" alternative, i am interested in knowing about it.

If i am correct, RemObjects should help with this IMHO.

Writing a pre-processor to handle conditionals should be quite straightforward. I doubt that there exists the pre-processor that you describe.

Remobjects has deliberately changed the product, so it is less compatible with Delphi in this area. It is not something they are going to undo.

So did my colleague think, before he started working on it. Nested ifdef's makes it complex, when also dealing with comments, strings etc.

You may wish to look at DelphiAST and at Uwe Raabe's UsesCleaner.

But getting actual values is much more tricky and messy
