1 Introduction

recursive-regex

This library integrates with CL-PPCRE to make named regex groups dispatch to custom matcher functions, which can recursively call another regex in the context of the original regex. It can then return a (parse) tree of results.

Some advantages of this approach

Modularize common regexp patterns so more reuse can be had
Allow non-regular expression matches by defering to custom match functions
Named groups matched in * expressions return all their results rather than the last match only (full parse tree of results, based on the named dispatchers)
Easy to expand your extant regular expressions to return better results (ie, I don't need to replce cl-ppcre with some parse, I can just keep using cl-ppcre)

Some disadvantages of this approach

Currently doesnt support a streaming interface
Not as well founded theoretically as other parser kits (ie: there are no shift/reduce or reduce/reduce errors flagged)
Not tested or optimized for performance.

Minor Example:

 (regex-recursive-groups #?r"function\s*(?<parens>)"
     "looking for function(call(), 1 ,2) type things")
 >> #<RESULT-NODE ROOT s:12 e:34 kids:1 "function(call(), 1 ,2)"  {1003341731}>
    (:ROOT "function(call(), 1 ,2)"
      (:MATCHED-PARENS "(call(), 1 ,2)"))

NB: Currently returns clos object trees and lisp-trees, because I want to play with it in the repl and see results but in practicality the CLOS result is probably what I want to work with.

Pre-Defined Dispatchers

body: 
    can be used in a definition to designate where the body 
    matcher should start matching. You can also provide a default
    body by specifying a regex inside the body in a definition.

parens, brackets, braces, angels:
    these all match a single matched pair 
    eg, for parens:
    not in the match (in (the) match) not in the match

single-quotes, double-quotes:
    single-quotes and double-quotes respect a single backslash as escape

comma-list: 
    [\t ]*(?:(?<body>[^,]*)[\t ]*,)*[\t ]*(?<body>[^,]*)[\t ]*
    the comma-list definition is (?<body>) separated by commas with
    arbitrary whitespace surrounding them. The default value of the
    body regex os [^,]*

csv-row:
    (?<comma-list>((?<double-quotes>)|[^\n,]*))(?:\n|$)
    calls the comma-list matcher passing in the body
    double-quotes-matcher or not new line or comma repeating
