Better error reporting for `with` expressions | 9658 |
with
expressions using non-attrset values to resolve variables are now reported with proper positions.
Previously an incorrect with
expression would report no position at all, making it hard to determine where the error originated:
nix-repl> with 1; a
error:
… <borked>
at «none»:0: (source not available)
error: value is an integer while a set was expected
Now position information is preserved and reported as with most other errors:
nix-repl> with 1; a
error:
… while evaluating the first subexpression of a with expression
at «string»:1:1:
1| with 1; a
| ^
error: value is an integer while a set was expected
