使用正则表达式匹配特定序列或其他所有内容

Question

Been trying to come up with a regex in JS that could split user input like :

"Hi{user,10,default} {foo,10,bar} Hello"

into:

["Hi","{user,10,default} ","{foo,10,bar} ","Hello"]

So far i achieved to split these strings with ({.+?,(?:.+?){2}})|([\\w\\d\\s]+) but the second capturing group is too exclusive, as I want every character to be matched in this group. Tried (.+?) but of course it fails...

Ideas fellow regex gurus?

Answer 1

Use this:

"Hi{user,10,default} {foo,10,bar} Hello".split(/(\{.*?\})/)

And you will get this

["Hi", "{user,10,default}", " ", "{foo,10,bar}", " Hello"]

Note: {.*?} . The question mark here ('?') stops at fist match of '}'.

Answer 2

Here's the regex I came up with:

(:?[^\{])+|(:?\{.+?\})

Like the one above, it includes that space as a match.

Answer 3

Beeing no JavaScript expert, I would suggest the following:

• get all positive matches using ({[^},]*,[^},]*,[^},]*?})
• remove all positive matches from the original string
• split up the remaining string

Allthough, this might get tricky if you need the resulting values in order.
