The 'again' macro is a new addition to the macro system, allowing for
recursive macro expansion. This commit introduces the necessary AST
nodes, macro expansion logic, and an integration test to ensure its
functionality. The `soa_series.myc` example has also been updated to
demonstrate its usage.
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.
Introduce new indicators for Simple Moving Average (SMA) and Weighted
Moving Average (WMA), along with their Hull Moving Average (HMA)
derivative.
Also refactors series implementation to use `RefCell` for interior
mutability and adds `SeriesMember` trait for better dynamic series
access. Updates `soa_series.myc` example to reflect new series creation
and push syntax.
This commit updates the benchmark and repeat counts for various example
files. These changes reflect potential performance improvements or
variations observed during testing.
Adds support for pipelines, allowing streams to be chained together and
transformed.
This includes new types for `PipeStream` and `SourceAdapter`, along with
modifications
to the `Environment` to manage pipeline execution. A new example
`pipeline.myc`
demonstrates its usage.
This commit introduces the `get_record` method to `RecordSeries`,
allowing for the dynamic reconstruction of a full record from its
constituent fields at a given index. This enables idiomatic access to
series data using indexing like `(my_ticks 0)`.
The `push-series` function has also been updated to correctly handle the
structure of records when pushing data into a `RecordSeries`.
Introduces a new RTL module for handling series data, enabling efficient
storage and retrieval of time-series data in a Struct-of-Arrays (SoA)
format.
Includes `SeriesView`, a zero-copy wrapper that provides a fast,
read-only interface to individual columns within a `RecordSeries`,
optimizing performance for data access in the VM.
Registers new native functions `create-series` and `push-series` for
managing series data.
