Importing constants from C headers?

[Shea Levy]

Hi all,

Is there a general way to import preprocessor-defined constants from C
headers into the statics language? $extval can't be used there.

I also wondered about this. I couldn't figure out how to do it, so I just defined it twice (see #define N in https://github.com/githwxi/ATS-Postiats-contrib/blob/master/contrib/libats-/bbarker/OpenMP/TEST/omp_for.dats). I agree this is not really satisfactory since it seems error prone.

Not sure what you want exactly.

I did something like this a while ago:

https://sourceforge.net/p/ats-lang/code/HEAD/tree/trunk/contrib/glib/HATS/glibconfig_hats

Then I used 'gcc -E' to preprocess glibconfig_hats to generate a HATS file glibconfig.hats, which
can be included in ATS code directly.

Ah, that's a clever approach. I'll try something like that, thanks!

The opposite direction is easier.

Say you store the following line in a file mydefine.hats

#define N 100

Then just put the following lines at the beginning of your code:

%{^
#include "define.hats"
%}
#include "define.hats"

It shouldn't be too bad ...

That would do it; somehow it never crossed my mind to #include a .hats file.
