[英]Replace with gsub a regexp with accents
I try to get a function for setting < b > around catched strings (case insensitive), like this : 我尝试获得一个在捕获的字符串周围设置<b>的函数(不区分大小写),如下所示:
bold_string("Hello everyone","o")
> "Hell<b>o</b> every<b>o</b>ne"
bold_string("HEllo evEryonE", "e")
> "H<b>E</b>llo <b>e</b>v<b>E</b>ryon<b>E<b/>"
Now, my function looks like that : 现在,我的函数如下所示:
def bold_string(str, search)
str.gsub(/(#{search})/i, '<b>\1</b>')
end
It works perfectly with the previous examples, but not with the words having some accents. 它与前面的示例完美地结合在一起,但不适用于带有重音符号的单词。 There are the results I expect :
有我期望的结果:
bold_string("Petite bête", "e")
> "P<b>e</b>tit<b>e</b> b<b>ê</b>t<b>e</b>"
bold_string("Petite bête", "ê")
> "P<b>e</b>tit<b>e</b> b<b>ê</b>t<b>e</b>"
In other words, I have to find a regex like /search/i, it says "you have to find the word 'search' or the word 'search' with some accents". 换句话说,我必须找到一个像/ search / i这样的正则表达式,它表示“您必须找到带有某些重音的单词'search'或'search'”。
edit : 编辑:
I see I was too simplist with my example... It should works with string and not simply chars : 我看到我的例子太简单了……它应该适用于string而不是chars:
bold_string("Petite bête", "êt")
> "P<b>et</b>ite</b> b<b>êt</b>e"

edit2 : I used the solution of FJ with this new function edit2:我将此新功能用于FJ解决方案
def regex_from_string_including_accents(str)
accents = ['aàâ', 'eéèêë', 'oöô' 'iî']
return str.gsub(/./) do |letter|
accent_group = accents.detect{|group| group.include?(letter)}
accent_group ? "[#{accent_group}]" : letter
end
end
You could do something like the following: 您可以执行以下操作:
def bold_string(str, search)
h = { "e" => "[eéê]", "a" => "[aáâ]" }
regex = search.gsub(/./) {|s| h.fetch(s, s)}
str.gsub(/(#{regex})/i, '<b>\1</b>')
end
Obviously this just shows you how to get started, you will need to fill h
with additional accented versions of characters. 显然,这只是向您显示了入门方法,您需要用其他带有重音符号的字符填充
h
。
