I am porting a large body of code from the MetaWare Professional Pascal compiler to Free Pascal. The existing code makes extensive use of the MetaWare "retype" construct, which allows you to convert between types. For example:

retype(X, Rec1Ptr) will convert the obect X to the type "Rec1Ptr".

Is it possible to do something equivalent in FPC?

There are > 1000 uses of this, and I'd prefer to make the minimal modifications.

Thanks.

To what extent does it actually convert the data? If it's a simple type cast, you can use Rec1Ptr(X) instead (should be easy to change with a regular expression), albeit with one caveat: if you use this to convert from an integer type to a floating point type, then the compiler will perform an actual value conversion (i.e., it will not just reinterpret the bitpattern, except possibly in Delphi mode).

It would not be that hard to add support for this expression to the compiler though.

As FPC (other than Delphi) features a Macro preprocessor, I suppose you can get away without modifying the code.

FPC does support macros but not parametrized ones.

No, you can't. FPC and Delphi macro's do not support parameters.

Any chance to use another preprocessor ?

So many choices, eg. sed?
