E50330: expected squirrelled data key not set on symbol

Category: Compiler development: the directive codes (E50200-E50390) · Classification: DIRECTIVE_SYMBOL_SQUIRRELLED_KEY_NOT_SET · All error codes

What went wrong

An @Squirrelled directive expected a squirrelled-data key to be set on the symbol, but that key carries no value.

Squirrelled data is the key/value metadata the compiler attaches to symbols so information set in an early phase is readable in a later one.

Note

This code concerns a compiler-development directive. The directives other than @Test (the ones that state what the compiler should report, resolve, measure or generate for a source) are tooling for the people who develop the EK9 compiler; they are not designed for mainstream programs, and a program needs none of them. The only directive an EK9 program uses is @Test.

How to fix it

If you are writing an EK9 program: remove the directive. Only @Test belongs in a program. If you are developing the compiler: docs/testing/EK9_DIRECTIVE_TEST_FILE_PROCESS.md in the compiler repository describes every directive and how to fix this report.

Compiler development

This code concerns the compiler-development directives (@Error, @Resolved, @Complexity and the rest), which are not designed for mainstream programs - the only directive a program uses is @Test, so it has no example. Compiler developers: docs/testing/EK9_DIRECTIVE_TEST_FILE_PROCESS.md in the compiler repository describes every directive.
