load-env very flaky & yields unexpected results #7149
Description
Describe the bug
I've been playing around with load-env and noticed unexpected behaviour.
- If one entry fails in any way, for example if a variable cannot be resolved, the entire
load-envblock is completely dismissed. - If an entire
load-envblock is dismissed due to an error of any kind, this all happens silently. The user does not get any message about it failing. In fact, it has to be specifically looked up or the user has to notice by accident how an environment variable is missing, even though it exists in theload-envblock. - "Compiling" the file with the
load-envblock does work and does not complain. No errors, no warnings, nothing.
How to reproduce
- Open a Nu file. For example,
test_load-env.nu. - Create a
load-envblock. - Assign an unresolvable (environment) variable to one of the record keys.
source test_load-env.nu- Try to resolve any record from the
load-envblock. None will be available and you didn't notice until now.
Expected behavior
Either an error should be shown on "compile" time and interrupt the compilation process, or every record should be evaluated, except the faulty one and an error or warning should be shown.
The most important point is the communication of what happened. The user must know, that something isn't right.
