6 years ago A few useful pointers from @kevinushey (thanks!) who developed similar support for Rstudio based on libclang:
R CMD SHLIB --dry-runto get the flags- Part of the relevant R studio code lives here
- Not all system headers that compilers include by default are included by libclang. So some extra tweaking will likely be necessary.
- New promising project cquery which does both compilation for semantic completion and indexing for a tag based completion. With emacs-cquery backend.
- ycmd is probably not worth it
Would be great to be able to generate configuration files for C/C++ completion engines irony and ycmd. See also this tutorial.
Both of them rely on libclang and likely making one of them work would trivially translate to another. If my understanding is correct we need to hack into R's CMD install and retrieve the compilation flags as R would do it.
This looks like a good feature for our ess-r-package.el. Maybe ess-r-package-generate-libclang-configs.
