How to write your own LCSPResolver

Read before start

lcsp works with custom resolvers - classes that should placed in your project and that will perform search locally.

You need to write resolver classes in Ruby because only this format accepting right now, but all work around search and parse for your repository you can place in classes/scripts/files in any other programming language.

One of the correct and working example available by this link.

Template class

path and number are default parameters that are presenting for every repository. This arguments describes user needs and gives you parameters to search.

# frozen_string_literal: true

module LCSP
  # Solutions finder.
  class LCSPFinder
    # @param {String} path
    # @param {String} number
    def initialize(path, number)
      @path = path
      @number = number
    end

    # @return {String}
    def solution
    end

    # @param {String} path
    # @param {String[]} dirs
    def fill_directories(path, dirs) end
  end
end

Reference class example

# frozen_string_literal: true

module LCSP
  # Solutions finder.
  class LCSPFinder
    # @param {String} path
    # @param {String} number
    def initialize(path, number)
      @path = path
      @number = number
    end

    # @return {String}
    def solution
      dirs = []
      fill_directories(@path, dirs)

      dirs.each do |directory|
        ::Dir.foreach(directory) do |entry|
          return "#{directory}/#{entry}" if entry.start_with?(@number)
        end
      end
    end

    # @param {String} path
    # @param {String[]} dirs
    def fill_directories(path, dirs)
      ::Dir.foreach(path).reject { |name| name.start_with?('.') }.each do |entry|
        unless ::File.file?("#{path}/#{entry}")
          dirs << "#{path}/#{entry}"
          fill_directories("#{path}/#{entry}", dirs)
        end
      end
    end
  end
end
