typelevel/cats-parse

This system is cats-parse, a functional parser combinator library for Scala that provides foundational parsing types and combinators for structured data. It supports cross-compilation across JVM, JavaScript, and Native platforms, offering specialized utilities for efficient bit-set operations and string matching. The library includes built-in parsers for common formats such as JSON, Semantic Versioning, and ABNF, along with comprehensive testing and benchmarking infrastructure.

New JSON resource files (bar.json, bla2.json, bla25.json) have been added to the bench module's resources directory to serve as input data for JSON parsing benchmarks.

This change introduces the core components of the cats-parse library, a functional parser combinator library for Scala. It adds the foundational \Parser\ and \Parser0\ types along with essential combinators, and provides utility classes for tracking parsing state such as \Caret\ for line/column offsets and \LocationMap\ for converting offsets to human-readable positions. The import also includes specific parsers for common data formats, including JSON strings and numbers, Semantic Versioning (SemVer) strings, and the common rules defined in RFC 5234 (ABNF). Additionally, it brings in internal optimization structures like \RadixNode\ for efficient string matching and \Accumulator\ types to support efficient result collection during parsing.

The repository has been initialized with core configuration files, including a \.scalafmt.conf\ that sets the formatting version to 3.11.5 and configures the Scala 2.13 dialect as the default (with Scala 3 support for \scala-3\ source directories). Additional setup includes a \.gitignore\ tailored for sbt and IDEs, a \PULL\_REQUEST\_TEMPLATE.md\ reminding contributors to run \sbt prePR\, and a \Release.md\ outlining the git-tag-based release process via GitHub Actions.

A new \BitSet.scala\ file has been added to the \core/native\ source directory, providing a \BitSetUtil\ object that extends \BitSetUtilCompat\ with specific boolean flags. This change enables the parser library to compile and function correctly on Scala Native targets by supplying the necessary bit-set utilities for that platform.

A new \BitSetUtil\ object has been added to the \core/js\ module, providing a JavaScript-specific implementation of the \BitSetUtilCompat\ trait. This change enables the parser library to utilize optimized bit-set operations on the JavaScript platform, supporting features such as fast character range checks and union iterators.

core/js · high confidence

The JVM module now includes a dedicated BitSet utility object that delegates to a compatibility layer with specific platform flags. This change provides a concrete implementation for bit-set operations on the JVM platform, distinct from other targets.

Added JVM-specific property tests for JSON number and string parsing; Added comprehensive test coverage for core parsing components.

This entry introduces the initial build configuration for the cats-parse library, establishing version 1.1 as the base release. It configures cross-compilation for Scala 2.12.21, 2.13.16, and Scala 3.3.6 across JVM, JS, and Native platforms. The build includes a core library module depending on Cats and Munit for testing, a benchmarking module for performance comparison, and a documentation site. It also sets up binary compatibility checks (MiMa) against the 0.3.x series and integrates GitHub Actions for coverage reporting.

(dependencies) · high confidence

The project's build system has been upgraded to sbt version 1.12.4, with the plugin configuration in project/plugins.sbt now including sbt-scala-native 0.5.12, sbt-scalajs 1.20.1, sbt-scoverage 2.4.4, and sbt-typelevel 0.8.2. Additionally, the dependency definitions in project/Dependencies.scala have been updated to use cats-core 2.13.0, munit 1.2.4, fastparse 3.1.1, and jawn-ast 1.6.0, while MimaExclusionRules.scala has been added to handle binary compatibility issues related to changes in the cats.parse library.
