Packages

coal-containers

Repository: codeberg.org/laserpants/coal-containers

A collection of functional data structures for the Coal programming language, providing efficient implementations of common container types.

  • Map — An AVL tree-based associative map with automatic balancing
  • Set — A set implementation built on top of Map
  • Tree — General-purpose tree structure (rose tree) with arbitrary children
  • NonEmpty.List — Type-safe non-empty list with guaranteed head element

Installation

coal add https://git@codeberg.org/laserpants/coal-containers.git

coal-monads

Repository: codeberg.org/laserpants/coal-monads

A collection of common monad implementations for the Coal programming language.

  • Reader – For shared environment access
  • State – For stateful computations
  • Writer – For computations that produce a log alongside a result

Installation

coal add https://git@codeberg.org/laserpants/coal-monads.git

coal-json

Repository: codeberg.org/laserpants/coal-json

A JSON library for the Coal programming language, providing encoding, decoding, and pretty-printing of JSON values with composable decoder combinators and typeclass-based serialization.

  • JsonValue type — A sum type representing all JSON primitives and compound values
  • Tokenizer/Parser — A two-phase parser (lexer + stack machine) with proper error handling
  • Encoder — Compact JSON encoding from JsonValue to string
  • Pretty-printer — Human-readable JSON output with configurable indentation
  • Decoder combinators — Composable decoders with combinators like field, array_decoder, map, and map2
  • Typeclass support — ToJson and FromJson traits for automatic serialization/deserialization

Installation

coal add https://git@codeberg.org/laserpants/coal-json.git

coal-micro-test

Repository: codeberg.org/laserpants/coal-micro-test

This library provides a simple and elegant way to write and run tests in Coal. It offers a functional approach to testing with assertion functions, test composition, and pretty-printed test results.

  • Simple assertions: assert and assert_eq for common test cases
  • Composable tests: Build complex test suites from simple test cases
  • Clear output: Color-coded test results with pass/fail summaries
  • Functional design: Leverages Coal's functional programming features
  • Lightweight: Minimal dependencies and straightforward API

Installation

coal add https://git@codeberg.org/laserpants/coal-micro-test.git

coal-pretty

Repository: codeberg.org/laserpants/coal-pretty

A pretty-printing library for the Coal programming language, providing a Pretty trait with instances for common built-in and composite types.

Installation

coal add https://git@codeberg.org/laserpants/coal-pretty.git

coal-parsers

Repository: codeberg.org/laserpants/coal-parsers

A parser combinator library with modular, composable parsers for text processing, language implementation, and data format parsing.

Installation

coal add https://git@codeberg.org/laserpants/coal-parsers.git

coal-event-source

Repository: codeberg.org/laserpants/coal-event-source

An event source library providing composable, blocking event sources with file descriptor and timer-based I/O multiplexing via select().

Installation

coal add https://git@codeberg.org/laserpants/coal-event-source.git

coal-variant

Repository: codeberg.org/laserpants/coal-variant

A dynamically typed value type that can represent primitives, strings, arrays, and objects.

Installation

coal add https://git@codeberg.org/laserpants/coal-variant.git

coal-uint8

Repository: codeberg.org/laserpants/coal-uint8

Fixed-width unsigned 8-bit integers with wrapping arithmetic and bitwise operations implemented on top of a small C runtime.

Installation

coal add https://git@codeberg.org/laserpants/coal-uint8.git

coal-datetime

Repository: codeberg.org/laserpants/coal-datetime

Date and time library providing absolute instants, civil dates and times, durations, fixed offsets, and pretty-printing

Installation

coal add https://git@codeberg.org/laserpants/coal-datetime.git

coal-array

Repository: codeberg.org/laserpants/coal-array

Contiguous, indexed arrays for the Coal programming language, implemented as an opaque heap-allocated type backed by a small C runtime

Installation

coal add https://git@codeberg.org/laserpants/coal-array.git
