hi there
just starting with the julia repl debugger but when I want to open the current line in an editor I get
```julia
About to run: (tuple)(2, 2)
1|debug> fr
[1] foo(n) at REPL[1]:1
| n::Int64 = 20
| x::Int64 = 21
1|debug> o
Could not find file: "REPL[1]"
1|debug>
```
how can I set up the debugger to set up xed ( my editor)
thank you

Unfortunately, the debugger cannot open an editor for a function that is not already stored in a file. Since this function was entered at the REPL, it exists only in memory. If you had loaded a function from a file (perhaps with `include("file.jl")`), this command would use the [`InteractiveUtils`](https://docs.julialang.org/en/v1/stdlib/InteractiveUtils/#InteractiveUtils.edit-Tuple%7BAbstractString,%20Integer%7D) stdlib to open the editor specified in one of the `JULIA_EDITOR` , `VISUAL` or `EDITOR` environment variables.
