[Bioc-devel] C library or C package API for regular expressions
Jirka, Do you mean with millions of different patterns (motifs)? If not, the R-level regular expression functions are vectorized, and so the looping will already happen for you in C. Also, have you confirmed that the R evaluation overhead will actually dominate the pattern matching here if you just do it in R? That very well may be, but it's not obvious to me that it would depending on details about what you're doing that I'm not privy to. Best, ~G On Tue, Jan 26, 2016 at 3:25 AM, Ji??

Hi Dan, nice to hear, I didn't notice. The only problem could be missing header files, but its bundling would solve it I hope. Jirka Dne 25.1.2016 v 23:38 Dan Tenenbaum napsal(a): R requires PCRE to build, therefore perhaps it is available for use within
packages? Dan ----- Original Message -----

Dear package developers,
I would like to ask you for advice. Please, what is the most seamless way to use regular expressions in C/C++ code of R/Bioconductor package? Is it allowed to bundle some C/C++ library for that (like PCRE or Boost.Regex)? Or is there existing C API of some package I can depend on and import? Thank you a lot for your attention and please have a nice day :) Jiri Hon
