Upcoming R version might break nvimcom

@jalvesaq do you have an idea?

[PMassicotte]

If this can be fixed, we are going to have a functional DAP inside neovim for R!

[jalvesaq]

I will see this now...

[jalvesaq]

We can manually build nvimcom in a terminal emulator because the function Rf_removeTaskCallbackByName is still declared in include/R_ext/Callbacks.h, but it is not available at run time and, consequently, when loading nvimcom, we get the error:

undefined symbol: Rf_removeTaskCallbackByName

[PMassicotte]

This is a bit out of my expertise. What does it mean exactly? Does it mean that there is a discrepancy between declaration and availability of some kind of function?

[jalvesaq]

Yes, it's a bug in R-devel. Probably, they removed the function on purpose but forgot to remove its declaration from the corresponding header file. We can report the bug and, then, they will either bring the function back or remove the declaration. Although no longer available in C, the function is still available in the R language. I will see if we can use it from R (not C).

[jalvesaq]

I moved the C code to R at the branch https://github.com/R-nvim/R.nvim/tree/R_task

wow you are fast (wish I had your skills!)

So far so good, I am using it. Let me try to configure dap.
