Previously, if you attempted to evaluate this file with the debugger:
|
||
|
|
|
||
|
|
```nix
|
||
|
|
let
|
||
|
|
a = builtins.trace "before inner break" (
|
||
|
|
builtins.break "hello"
|
||
|
|
);
|
||
|
|
b = builtins.trace "before outer break" (
|
||
|
|
builtins.break a
|
||
|
|
);
|
||
|
|
in
|
||
|
|
b
|
||
|
|
```
|
||
|
|
|
||
|
|
Nix would correctly enter the debugger at `builtins.break a`, but if you asked
|
||
|
|
it to `:continue`, it would skip over the `builtins.break "hello"` expression
|
||
|
|
entirely.
|
||
|
|
|
||
|
|
Now, Nix will correctly enter the debugger at both breakpoints.
