[英]gsub string for all spaces in Ruby 1.8
I have a string with spaces (one simple space and one ideographic space): 我有一个带空格的字符串(一个简单空格和一个表意空间):
"qwe rty uiop".gsub(/[\s]+/,'') #=> "qwe rtyuiop"
How can I add all space-codes (for example 3000, 2060, 205f) in my pattern? 如何在我的模式中添加所有空格代码(例如3000,2060,205f)?
In Ruby 1.9 I just added \
and other codes, but how do it in 1.8? 在Ruby 1.9中,我刚刚添加了\
和其他代码,但是如何在1.8中添加?
I think i found answer. 我想我找到了答案。 In ActiveSupport::Multibyte::Chars is a UNOCODE_WHITESPACE constant. 在ActiveSupport :: Multibyte :: Chars中是UNOCODE_WHITESPACE常量。 Solution: 解:
pattern = ActiveSupport::Multibyte::Chars::UNICODE_WHITESPACE.collect do |c|
c.pack "U*"
end.join '|'
puts "qwe rty uiop".mb_chars.gsub(/#{pattern}/,'')
#=> qwertyuiop
