This commit introduces `StaticType::Variadic` to represent variadic
parameter types in function signatures. This allows for more precise
type checking of functions that accept a variable number of arguments,
such as arithmetic operators.
Previously, variadic functions were handled using `StaticType::Any`,
which was too permissive and could lead to runtime errors. The new
`Variadic` type enforces that all arguments must conform to a specified
inner type.
Changes include:
- Adding `StaticType::Variadic` to `src/ast/types.rs`.
- Updating the type checker to handle `Variadic` types correctly when
unifying with tuples or single arguments.
- Modifying built-in functions like arithmetic operators to use
`Variadic` for their parameter types.
- Improving error messages for function call mismatches to be more
specific.
- Adding a new test case to ensure arithmetic type mismatches are caught
at compile time.
- A new example `data_stream_pipe_buffered.myc` is added.
- The `HMA.myc` example now has a `Skip: output` directive.
The `bound_nodes.rs` file has been removed and its contents have been
moved to `src/ast/nodes.rs`. This consolidates all AST node definitions
into a single module, improving organization and maintainability.
The `compiler` modules now import these definitions from
`crate::ast::nodes` instead of `crate::ast::compiler::bound_nodes`.
This commit refactors the test suite by removing the monolithic
`integration_test.rs` file.
The tests have been categorized and moved into dedicated modules within
the `tests/` directory:
- `tests/parser.rs`: Contains tests for parsing various literal values.
- `tests/destructuring.rs`: Houses tests related to destructuring
syntax.
- `tests/closures.rs`: Includes tests for closure behavior and related
optimizations.
- `tests/optimizer.rs`: Contains tests specifically targeting optimizer
logic and regressions.
- `tests/records.rs`: Holds tests for record syntax and associated
optimizations.
- `tests/rtl.rs`: Contains tests for runtime library operators and
functions.
- `tests/pipeline.rs`: Tests for pipeline functionality.
- `tests/macros.rs`: Tests for macro expansion and related issues.
- `tests/error_recovery.rs`: Includes tests for compiler error handling
and recovery mechanisms.
- `tests/examples.rs`: Verifies the execution of example scripts.
This reorganization improves test discoverability and maintainability.
The `lib.rs` file has also been updated to reflect these changes by
removing the reference to the old `integration_test` module.
The `type_checker.rs` file has had some tests removed, as they are now
covered by the more specific tests in `tests/error_recovery.rs`.
