Handy libraries

Bunch of somewhat usable libraries without any particular direction.

Approximate structure:

  • org.gorttar.control - declarations of custom control structures
    • managed value - provides a way to run a block of code on some stateful value preserving its old state before execution and restoring it after. May be useful for temporarily changing some global environment such as system in/out console streams, root logger log level etc.
  • org.gorttar.data - declarations of custom data structures/operations on them
    • sequence equality - fun eq checks two sequences for structural equality with the following limitations/behavior details:
      • it actually iterates over sequences so them would better be able to iterate multiple times
      • it can't check infinite equal sequences for equality but can determine their inequality
    • org.gorttar.data.heterogeneous.list - immutable heterogeneous list implementation inspired by Strongly Typed Heterogeneous Collections article
      • org.gorttar.data.heterogeneous.list.generators - bunch of utility classes to generate boilerplate code
      • Aliases.kt - auto generated file with type aliases intended to shorten list signatures
      • Destructuring.kt - auto generated file declaring componentN operators for lists up to 26 elements
      • ExtensionProperties.kt - auto generated file declaring a..z extension properties for lists up to 26 elements
      • HList.kt - main data structure declaration
      • Literals.kt - auto generated file declaring hListOf factory functions for lists up to 26 elements
  • org.gorttar.graphics.turtle - simple turtle graphics library for Kotlin. See Koch flake example for more details
  • org.gorttar.repr.repr - reflective String representation of arbitrary objects
  • org.gorttar.test.io - simple expect like library. Still WIP
