Ruby：从YAML添加哈希/合并对象

Question

我有两个已序列化的YAML文件。

“PP”来自

ἀγαπάω:
  present: ἀγαπάω
  future: ἀγαπήσω
  aorist: ἠγάπησα

......还有更多......

“lexemes”来自

ἀγαπάω:
    pos: V
    bdag-headword: ἀγαπάω
    strongs: 25
    gloss: I love
...many more...

我正在尝试将“gloss”和“strongs”的值添加到“pp”，或者将pp值与来自lexemes的这些新值合并。显然ruby不允许在迭代哈希时插入新值。到目前为止，我有：

pps = Hash.new
pp.each do |p|
lexemes.each do |lex, arr| 
  if lex.match /^#{p[0]}$/
    #match found
    puts "p #{p[0]} ... lex #{lex}...#{arr['strongs']}....#{arr['gloss']} .
  (pps[p[0]] ||= []) << p
  pps[p[0]].push(:strongs => arr['strongs'], :gloss => arr['gloss'])
  end
end
end

当转储时产生：

"ἀγαπάω":
- - "ἀγαπάω"
  - present: "ἀγαπάω"
    future: "ἀγαπήσω"
    aorist: "ἠγάπησα"
- :strongs: 25
  :gloss: I love

当我真正想要的时候：

ἀγαπάω:
  present: ἀγαπάω
  future: ἀγαπήσω
  aorist: ἠγάπησα
  strongs: 25
  gloss: I love

知道我应该在哪里/如何管理新数据的插入？

谢谢！

此构造||= []是Array的初始化，只是尽量避免它。要合并两个Hash es，只需使用#merge方法：

h1 = { h1: { hh1: 1, hh2: 2}}
# => {:h1=>{:hh1=>1, :hh2=>2}}
h2 = { h1: { hh3: 3, hh4: 4}}
# => {:h1=>{:hh3=>3, :hh4=>4}}
h1[:h1].merge(h2[:h1])
# => {:hh1=>1, :hh2=>2, :hh3=>3, :hh4=>4}
