ruby テキストファイル変換

Question

テキストファイルをCSV ファイルに変換し、

さらにカンマ区切りでダブルクォーテーションでくくりたいのですがやり方がよくわかりません。

どなたかわかる方いたら教えてください。

yasui	men	20   170
tanaka	men	10   180
satou	men	9    160
yosida	men	17   150

Answer 1

Rubyなど不要。そう、シェル芸ならね！

$ cat text
yasui    men    20   170
tanaka    men    10   180
satou    men    9    160
yosida    men    17   150

$ cat text|awk '$0="\""$1"\",\""$2"\",\""$3"\",\""$4"\""'
"yasui","men","20","170"
"tanaka","men","10","180"
"satou","men","9","160"
"yosida","men","17","150"

Answer 2

open('out.csv', 'w') do |out|
  File.read('in.txt').split("\n").each do |line|
    out.puts(line.split("\s").map { |e| '"' + e.strip + '"' }.join(','))
  end
end

in.txt

yasui    men    20   170
tanaka    men    10   180
satou    men    9    160
yosida    men    17   150

out.csv

"yasui","men","20","170"
"tanaka","men","10","180"
"satou","men","9","160"
"yosida","men","17","150"
