The `series` constructor now only accepts the `lookback` limit. The
element type is inferred by the type checker and implicitly added as a
schema argument during compilation. This simplifies the API and
centralizes type inference.
This change also includes:
- Updates to example scripts (`HMA.myc`, `sma.myc`, `soa_series.myc`) to
reflect the new `series` signature.
- Modifications to the `TypeChecker` to handle the inferred schema
injection.
- An addition of a regression test for type inference through nested
closures with `series`.
- Removal of `#[allow(dead_code)]` from several `TypeChecker` methods as
they are now used.
- Update to `rtl/prelude.myc` macro `cache`.
- Update to `rtl/series/mod.rs` to reflect new signature.
- Update to `ast/types.rs` to allow `series` to be indexed with an
integer to retrieve its element type.
This commit reorganizes the series-related code by moving the
`RingBuffer`, `ScalarSeries`, `ValueSeries`, `RecordSeries`,
`SeriesView`, and `SharedSeries` structs into a new
`src/ast/rtl/series/data.rs` file.
The `src/ast/rtl/series/mod.rs` file now contains the module
declaration, re-exports, and the `register` function for registering
series-related native functions with the environment. This improves code
organization and maintainability.
- Add `rtl/system.myc` as the system library, containing core utilities
like `while` and `cache`.
- Remove the duplicate `prelude.myc` from `src/ast/rtl/`.
- Modify `Environment::collect_dependencies` to implicitly add `#use
system` when necessary.
- Update `Environment::with_cwd` to also add the `rtl` subdirectory to
search paths.
- Add `target/` to `.geminiignore` to exclude build artifacts.
- Adjust example `sma.myc` to use the new `cache` macro and reduce
sample data size.
- Update `rtl/sma.myc` to correctly initialize the `history` series with
its `length`.
- Add `preload_dependencies` calls to `dump_ast` and `run_script` for
proper module loading.
The `PipelineNode` has been refactored into `StreamNode`. This commit
updates the example files to reflect this change and also updates the
`series` constructor to accept a lookback parameter.
The `PipelineNode` was an artifact of a previous implementation and is
no longer needed. The `StreamNode` is the appropriate type for
representing the output of a pipe operation.
The `series` function now requires a `lookback` argument to specify the
maximum number of items to store. This makes the behavior of series more
explicit and prevents accidental unbounded memory growth.
This commit introduces a new prelude file that defines the `while` macro
and registers it during environment bootstrapping. The `again` macro has
been updated to accept multiple arguments for its recursive call, and
several examples have been adjusted to reflect this change.
Additionally, the `MacroRegistry` in the compiler is now cloneable and
can be moved out of the `MacroExpander`.
