Question

I was wondering if there was a way to remove everything between two carrots from a string:

"<@000000> I thought you said this would happen?"

to get:

"I thought you said this would happen?"

I thought using global substitution would work. I attempted with this code:

somefile = File.open("Test_Teleó.txt", "a+")
  jdoc.fetch("messages").each do |body|
    ts = body["ts"].to_i
    somefile.puts body["text"].gsub(/[<]/, '').gsub(/[>]/, '').chomp
  end

And the output is:

@000000 I thought you said this would happen?

It only removed the carrots and not the between characters.

Any advice?

只需对代码进行微调：

File.open("Test_Teleó.txt", "a+") do |somefile|
  jdoc.fetch("messages").each do |body|
    ts = body["ts"].to_i
    somefile.puts body["text"].gsub(/<[^>]*>/, '').chomp 
  end
end

我也在这里使用块样式open，因为它会在块完成时自动关闭文件。这有助于避免忘记和意外打开文件。
