/**
|
||||
* Matches block comment delimiters
|
||||
*
|
||||
* While most of this pattern is straightforward the attribute parsing
|
||||
* incorporates a tricks to make sure we don't choke on specific input
|
||||
*
|
||||
* - since JavaScript has no possessive quantifier or atomic grouping
|
||||
* we are emulating it with a trick
|
||||
*
|
||||
* we want a possessive quantifier or atomic group to prevent backtracking
|
||||
* on the `}`s should we fail to match the remainder of the pattern
|
||||
*
|
||||
* we can emulate this with a positive lookahead and back reference
|
||||
* (a++)*c === ((?=(a+))\1)*c
|
||||
*
|
||||
* let's examine an example:
|
||||
* - /(a+)*c/.test('aaaaaaaaaaaaad') fails after over 49,000 steps
|
||||
* - /(a++)*c/.test('aaaaaaaaaaaaad') fails after 85 steps
|
||||
* - /(?>a+)*c/.test('aaaaaaaaaaaaad') fails after 126 steps
|
||||
*
|
||||
* this is because the possessive `++` and the atomic group `(?>)`
|
||||
* tell the engine that all those `a`s belong together as a single group
|
||||
* and so it won't split it up when stepping backwards to try and match
|
||||
*
|
||||
* if we use /((?=(a+))\1)*c/ then we get the same behavior as the atomic group
|
||||
* or possessive and prevent the backtracking because the `a+` is matched but
|
||||
* not captured. thus, we find the long string of `a`s and remember it, then
|
||||
* reference it as a whole unit inside our pattern
|
||||
*
|
||||
* @cite http://instanceof.me/post/52245507631/regex-emulate-atomic-grouping-with-lookahead
|
||||
* @cite http://blog.stevenlevithan.com/archives/mimic-atomic-groups
|
||||
* @cite https://javascript.info/regexp-infinite-backtracking-problem
|
||||
*
|
||||
* once browsers reliably support atomic grouping or possessive
|
||||
* quantifiers natively we should remove this trick and simplify
|
||||
*
