    SPaC (short for "Streaming Parser Combinators") is a library for building stream consumers in a declarative style, specialized for tree-like data types like XML and JSON.

    SPaC (short for "Streaming Parser Combinators") is a library for building stream consumers in a declarative style, specialized for tree-like data types like XML and JSON.

    Many utilities for handling XML and JSON data involve parsing the entire "document" to some DOM model, then inspecting and transforming that model to extract information. The downside to these utilities is that when the document is very large, the DOM may not fit in memory. The workaround for this type of problem is to treat the document as a stream of "events", e.g. "StartElement" and "EndElement" for XML, or "StartObject" and "EndObject" for JSON. The downside to this workaround is that writing code to handle these streams can be complicated and error-prone, especially when the DOM is complicated.

    SPaC's goal is to drastically simplify the process of creating code to handle these streams.

    This package contains the "core" SPaC traits; Parser, Transformer, Splitter, and ContextMatcher.

    See the xml and json subpackages (provided by the xml-spac and json-spac libraries respectively) for specific utilities related to handling XML and JSON event streams.

implicit final class SourceFs2Ops[A] extends AnyVal

Since Source is a synchronous-only encoding of the Resource pattern, it can be converted to a cats.effect.Resource by suspending its open and close operations in a Sync effect type F, yielding an Iterator[A] as its value.

This can be taken a step further by lifting that Resource to a fs2.Stream and wrapping the provided Iterator as a stream, to treat the whole Source[A] as a fs2.Stream[F, A]

  14. def toResource[F[_]](implicit arg0: Sync[F]): Resource[F, Iterator[A]]

    Upgrades this Source to a cats-effect Resource of the given effect type F.

    Upgrades this Source to a cats-effect Resource of the given effect type F. The open and close operations of the underlying source are assumed to be blocking, so they are wrapped with Sync[F].blocking { ... }.

    F

    The effect type

    returns

    A new Resource which delegates to this Source's open method

  15. def toStream[F[_]](chunkSize: Int = 32)(implicit F: Sync[F], FM: MonadCancel[F, _]): Stream[F, A]

    Converts this Source to an fs2 Stream in the given effect type F.

    Converts this Source to an fs2 Stream in the given effect type F.

    Uses toResource to encapsulate the underlying open/close operation, and uses Stream.fromBlockingIterator to wrap the underlying Iterator provided by the Source. The underlying Iterator is assumed to use blocking operations internally since typically the Iterator would be backed by something like a java.io.InputStream.

    F

    The effect type

    chunkSize

    The number of times the underlying Iterator's next should be called, per blocking step

    F

    Sync[F] typeclass instance

    FM

    MonadCancel[F, _] typeclass instance

    returns

    A Stream over the data provided by the underlying Source
