fixes #22950 This pull request improves the tracking and reporting of effect annotations (such as `raises`, `tags`, and `forbids`) in pragma blocks, particularly when using the `cast` pragma. It ensures that the source of these effect annotations is correctly preserved and referenced, which improves error reporting and effect analysis. Additionally, a new test was added to check for violations when using `cast` with effect annotations. Effect annotation source tracking and propagation: * Added new fields (`excSource`, `tagsSource`, `forbidsSource`) to the `PragmaBlockContext` type to store the original source node for each effect annotation. * Updated `castBlock` to set these new source fields when processing `raises`, `tags`, and `forbids` pragmas, ensuring the source node is preserved for later error reporting. * Modified `unapplyBlockContext` to use the stored source node (if available) when calling `addRaiseEffect`, `addTag`, and `addNotTag`, improving the accuracy of effect tracking and diagnostics. Pragma handling improvements: * Changed the call to `castBlock` in the main pragma processing loop to pass the entire pragma node, enabling access to the original source for effect annotations. Testing: * Added a new test (`tests/effects/tcast_effect_violation.nim`) to verify that using `cast(raises: ValueError)` inside a procedure with `.raises: [].` correctly triggers an error message about an unlisted exception.
This directory contains the test cases.
Each test must have a filename of the form: t*.nim
Note: Testament is only aware of tests under a directory (eg tests/foo/) and will ignore
top-level tests like tests/tbar.nim.
Specs
Each test can contain a spec in a discard """ ... """ block.
Check out the parseSpec procedure in the specs module for a full and reliable reference
action
Specifies what action this test should take.
Default: run
Options:
compile- compiles the module and fails the test if compilations fails.run- compiles and runs the module, fails the test if compilation or execution of test code fails.reject- compiles the module and fails the test if compilation succeeds.
There are certain spec keys that imply run, including output and
outputsub.
Categories
Each folder under this directory represents a test category, which can be
tested by running koch tests pcat <category> (or cat to avoid parallel
testing, which is slower).
The folder dll contains simple DLL tests.
The folder realtimeGC contains a test for validating that the realtime GC
can run properly without linking against the nimrtl.dll/so.
