Ruby on Rails locales-find script for fuzzy searching through locales yaml files using full dot notation part

Hacked together a quick ruby script for fuzzy searching for locale keys with their full dot notation part. It loads all yaml files in config/locales, flattenes all the key paths like sv.foo.bar.baz and prints the value and filename after. The result is passed through fzf for fuzzy filtering.

bin/locales-find | fzf --ansi -e

or maybe: docker-compose run --rm web bin/locales-find 2>/dev/null | fzf --ansi -e

bin/locales-find

#!/usr/bin/env ruby

require "pathname"
ENV["BUNDLE_GEMFILE"] ||= File.expand_path("../../Gemfile",
  Pathname.new(__FILE__).realpath)

require "rubygems"
require "bundler/setup"
require "colorize"
require "yaml"

def main
  flattened_locales.each do |(key, val, file)|
    puts "#{key.red}: #{val} - #{file.bold}"
  end
end

def flattened_locales
  Dir["config/locales/*.yml"].flat_map do |path|
    hash = YAML.safe_load(File.read(path), aliases: true)
    file = path.split("/")[2..].join("/")
    flatten_hash(hash).map { |arr| arr << file }
  end.sort_by { |(key)| key[3..] }
end

def flatten_hash(obj, key_path = nil)
  case obj
  when Array
    obj.flat_map.with_index { |o, i| flatten_hash(o, [key_path, i].compact.join(".")) }
  when Hash
    obj.flat_map { |k, o| flatten_hash(o, [key_path, k].compact.join(".")) }
  else
    [[key_path, obj]]
  end
end

main
