CLI tool to get function name from line of source code

Has anyone written a CLI tool/script that when given a file path (to a .ex or .exs) file and a line number, will return the module name and function? i.e.

$ extract_line_number.bash ~/code/my_cool_proj/lib/utils.ex:15
MyCoolProj.Utils.find_by_id/2

This could be probably be built using the Elixir treesitter grammar (are there already any CLI tools that use the grammar in similar ways?). Before I embark on writing such a tool/script I wanted to see if anyone has already written one.

You should be able to use ast-grep for this.
