sourceCpp code argument

[Gabor Grothendieck]

Could you add the code= argument that is in Rcpp:;sourceCpp to attributes::sourceCpp.  

I find it useful for creating self-contained single file runs.

That is the perfect case for creating an account on github and start creating issues. Even if you just use the account for that it makes sense. 

This mailing list is more meant for general questions about R/C++. This really is a feature request. Of course I can go ahead and translate this email into a feature request on github, but I can also forget to do it.

I have opened this issue, as I do agree with you that it is a nice feature. I'm currently doing some refactoring work on Rcpp11, so I might not get to this for a few days. Perhaps Kevin will get there first.

It would be simple enough to write anyway, so perhaps someone will open a pull request for it.

Hi Gabor,

I've implemented this in attributes now -- can you try getting the latest version from GitHub and giving it a whirl?

Thanks,

Kevin

Thanks! I just re-installed Rcpp11 and atributes and then tried the
following example and it worked:


code <- '
#include <Rcpp.h>
#include <boost/range/irange.hpp>

// [[Rcpp::depends(BH)]]

// [[Rcpp::export]]
int useCpp11() {
auto sum = 0;
for(const auto i : boost::irange(0,4)) { sum += i; }
return sum;
}
'

library(Rcpp11)
library(attributes)
sourceCpp(code = code)
useCpp11()
