Open Source Adventures: Episode 38: Update script for Russian Losses App

I linked to the Russian Losses App many times in various internet arguments. It doesn't currently have a permanent URL for the latest version, and various versions just reflect state of the code at given point.

It makes sense to keep the code as is, but I still want each version to have the latest data. So I wrote this script:

#!/usr/bin/env rubyrequire "pathname"class UpdateCSV  def initialize(archive_path)    @archive_path = Pathname(archive_path)  end  def updated_equipment    @updated_equipment ||= (@archive_path + "russia_losses_equipment.csv").read  end  def updated_personnel    @updated_personnel ||= (@archive_path + "russia_losses_personnel.csv").read  end  def csv_files    @csv_files ||= `git ls`.lines.map(&:chomp).grep(/\.csv\z/)  end  def call    csv_files.each do |path|      case path      when /russia_losses_equipment/        Pathname(path).write(updated_equipment)      when /russia_losses_personnel/        Pathname(path).write(updated_personnel)      else        puts "Unknown CSV file: #{path}"      end    end  endendunless ARGV[0]  STDERR.puts "Usage: #{$0} path_to_updated_archive"  exit 1endUpdateCSV.new(ARGV[0]).call

To run it, I grab updated version from Kaggle, unpack it, and then run the update script.

There's a lot of files it needs to update. The ones in docs are GitHub Pages compiled app:

Coming next

Over the next few episodes, I want to add a few new features to the Russian losses tracker.
