Chris Double 1c6882b32c Rip out packrat stuff 
It was broken since the transition to generating compiled quotations. As far as I know, no one was using packrat-parse anyway.
Rework in progress...

Chris Double 44954753bd Change <EBNF .. EBNF> to [EBNF .. EBNF] 2008-03-20 17:13:27 +13:00
Chris Double e7980ebc61 More refactoring of EBNF 
<EBNF .. EBNF> now produces a quotation that when called does the parsing
EBNF: foo ... ;EBNF creates a 'foo' word with stack effect (string -- result)
when called it parses the string and returns the result.

Chris Double 39c228db6d Update peg.pl0 to use range pattern syntax 
This allows removing the words for ident and number, replacing them
with EBNF expressions.

Chris Double 795ef0ae3b Add ranges to EBNF syntax 
This works:
  <EBNF letter = [a-zA-Z] EBNF>
and
  <EBNF not-digit = [^0-9] EBNF>

Chris Double 92d8140d87 Change ebnf-action to properly nest with attached parser 
This allows removal of last-parser hack. Syntax of EBNF changes though.
Now an action must attach to a group:

  <EBNF foo = (a b c) [[ ...act on group... ]] EBNF>
 2008-03-20 03:05:40 +13:00
Chris Double 65fabeec11 remove => action and replace it with [[ code ]] in EBNF 
Previously the action had to be a factor word and could only appear at the end of a rule:

  : aword ( ast -- ast ) drop V{ 1 2 } ;
  <EBNF foo = "a" "b" => aword EBNF>

Now actions can appear anywhere after an element, and can be any factor code between [[ ... ]] delimiters:

  <EBNF foo = "a" "b" [[ drop V{ 1 2 } ]] EBNF>
  <EBNF foo = "a" [[ drop 1 ]] "b" [[ drop 2 ]] EBNF>

Unfortunately since this means the ebnf>quot code uses the equivalent of eval, it no longer compiles nicely since it can't be inferred. The generated parsers however do compile.

Added ( ... )+
 2008-03-20 01:18:09 +13:00
Chris Double 64135b73e1 Add support for ensure-not and parsing any single character to EBNF 
This allows, for example:
  foo = {!("_" | "-") .}

This will match zero or more of any character, except for _ or -
