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

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.

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 -
