Question about pegjs way of writing some lpeg rules

Description

I am a LPeg.re user and I'm used to these features provided by LPeg

Syntax	Description
p^num	exactly n repetitions
p^+num	at least n repetitions
p^-num	at most n repetitions
p => name	match-time capture equivalent to lpeg.Cmt(p, defs[name])

PEG.js is great but when I want to migrate these rules, I don't know how to get the same functionality. The first three are about specifying the number of repetitions of a pattern. The last one is about a function that could decide if the match is success, or change the offset of the end of match, with information of the input, current position and captures.

Software

• PEG.js: 0.10.0 online version

@futagoza - This issue is 30 days old and you haven't answered it yet.

@AlexanderMisel - peg doesn't have those. You would have to implement them in regular expressions or javascript
