Is there a fast way to send function defintions?

[SimonCW]

Hey,
is there a fast way to send function definitions? I cannot figure out how you do it in the gif from the Readme https://asciinema.org/a/495376.

For a function

def fn1(a, b):
    ```This is doing something````
    return 3*a+b

When finished typing the return statement, I'd like to send the function to ipython.
Currently, I type <space>sc (to send a motion) and then 3k to send the 3 lines up. Alternatively, I could do <space>sc{

Is there a more ergonomic way to do this?

Yes, via treesitter textobjects: https://github.com/nvim-treesitter/nvim-treesitter-textobjects

So if you have mapped, for instance, gs as send motion in iron and af for @function.outer for treesitter, you could just do gsaf.

@jolars how would this work for R ?

It seems that the suggested approach only sends, e.g.

function(x) {
  return(x^2)
}

without the function name instead of:

square <- function(x) {
  return(x^2)
}

Yes, that's a problem with how the function text object is defined in the treesitter parser for R. I agree it's annoying. I am guessing you might be able to redefine or use some plugin to handle this, to include the nodes for the assignment operator and object the function is assigned to, but I haven't experimented with this.
