} - optional: is invoked when the parse terminates due to success ('accept') or failure - (even when exceptions are thrown). `retval` contains the return value to be produced - by `Parser.parse()`; this function can override the return value by returning another. - When it does not return any value, the parser will return the original `retval`. - This function is invoked immediately before `Parser.post_parse()`. - parseError: function(str, hash) - optional: overrides the default `parseError` function. - } - - parser.lexer.options: { - ranges: boolean optional: true ==> token location info will include a .range[] member. - flex: boolean optional: true ==> flex-like lexing behaviour where the rules are tested - exhaustively to find the longest match. - backtrack_lexer: boolean - optional: true ==> lexer regexes are tested in order and for each matching - regex the action code is invoked; the lexer terminates - the scan when a token is returned by the action code. - pre_lex: function() - optional: is invoked before the lexer is invoked to produce another token. - `this` refers to the Lexer object. - post_lex: function(token) { return token; } - optional: is invoked when the lexer has produced a token `token`; - this function can override the returned token value by returning another. - When it does not return any (truthy) value, the lexer will return the original `token`. - `this` refers to the Lexer object. + expected: (string describing the set of expected tokens) + recoverable: (boolean: TRUE when the parser has a error recovery rule available for this particular error) } */ -var parser = (function(){ +var bnf = (function(){ var parser = {trace: function trace() { }, yy: {}, -symbols_: {"error":2,"spec":3,"declaration_list":4,"%%":5,"grammar":6,"optional_end_block":7,"EOF":8,"CODE":9,"optional_action_header_block":10,"ACTION":11,"declaration":12,"START":13,"id":14,"LEX_BLOCK":15,"operator":16,"parse_param":17,"PARSE_PARAM":18,"token_list":19,"associativity":20,"LEFT":21,"RIGHT":22,"NONASSOC":23,"symbol":24,"production_list":25,"production":26,":":27,"handle_list":28,";":29,"|":30,"handle_action":31,"handle":32,"prec":33,"action":34,"expression_suffix":35,"handle_sublist":36,"expression":37,"suffix":38,"ALIAS":39,"ID":40,"STRING":41,"(":42,")":43,"*":44,"?":45,"+":46,"PREC":47,"{":48,"action_body":49,"}":50,"ARROW_ACTION":51,"action_comments_body":52,"ACTION_BODY":53,"$accept":0,"$end":1}, -terminals_: {2:"error",5:"%%",8:"EOF",9:"CODE",11:"ACTION",13:"START",15:"LEX_BLOCK",18:"PARSE_PARAM",21:"LEFT",22:"RIGHT",23:"NONASSOC",27:":",29:";",30:"|",39:"ALIAS",40:"ID",41:"STRING",42:"(",43:")",44:"*",45:"?",46:"+",47:"PREC",48:"{",50:"}",51:"ARROW_ACTION",53:"ACTION_BODY"}, -productions_: [0,[3,5],[3,6],[7,0],[7,1],[10,0],[10,2],[4,2],[4,0],[12,2],[12,1],[12,1],[12,1],[12,1],[17,2],[16,2],[20,1],[20,1],[20,1],[19,2],[19,1],[6,2],[25,2],[25,1],[26,4],[28,3],[28,1],[31,3],[32,2],[32,0],[36,3],[36,1],[35,3],[35,2],[37,1],[37,1],[37,3],[38,0],[38,1],[38,1],[38,1],[33,2],[33,0],[24,1],[24,1],[14,1],[34,3],[34,1],[34,1],[34,0],[49,0],[49,1],[49,5],[49,4],[52,1],[52,2]], +symbols_: {"error":2,"spec":3,"declaration_list":4,"%%":5,"grammar":6,"optional_end_block":7,"EOF":8,"CODE":9,"optional_action_header_block":10,"ACTION":11,"declaration":12,"START":13,"id":14,"LEX_BLOCK":15,"operator":16,"parse_param":17,"options":18,"OPTIONS":19,"token_list":20,"PARSE_PARAM":21,"associativity":22,"LEFT":23,"RIGHT":24,"NONASSOC":25,"symbol":26,"production_list":27,"production":28,":":29,"handle_list":30,";":31,"|":32,"handle_action":33,"handle":34,"prec":35,"action":36,"expression_suffix":37,"handle_sublist":38,"expression":39,"suffix":40,"ALIAS":41,"ID":42,"STRING":43,"(":44,")":45,"*":46,"?":47,"+":48,"PREC":49,"{":50,"action_body":51,"}":52,"ARROW_ACTION":53,"action_comments_body":54,"ACTION_BODY":55,"$accept":0,"$end":1}, +terminals_: {2:"error",5:"%%",8:"EOF",9:"CODE",11:"ACTION",13:"START",15:"LEX_BLOCK",19:"OPTIONS",21:"PARSE_PARAM",23:"LEFT",24:"RIGHT",25:"NONASSOC",29:":",31:";",32:"|",41:"ALIAS",42:"ID",43:"STRING",44:"(",45:")",46:"*",47:"?",48:"+",49:"PREC",50:"{",52:"}",53:"ARROW_ACTION",55:"ACTION_BODY"}, +productions_: [0,[3,5],[3,6],[7,0],[7,1],[10,0],[10,2],[4,2],[4,0],[12,2],[12,1],[12,1],[12,1],[12,1],[12,1],[18,2],[17,2],[16,2],[22,1],[22,1],[22,1],[20,2],[20,1],[6,2],[27,2],[27,1],[28,4],[30,3],[30,1],[33,3],[34,2],[34,0],[38,3],[38,1],[37,3],[37,2],[39,1],[39,1],[39,3],[40,0],[40,1],[40,1],[40,1],[35,2],[35,0],[26,1],[26,1],[14,1],[36,3],[36,1],[36,1],[36,0],[51,0],[51,1],[51,5],[51,4],[54,1],[54,2]], performAction: function anonymous(yytext, yyleng, yylineno, yy, yystate /* action[1] */, $$ /* vstack */, _$ /* lstack */) { /* this == yyval */ var $0 = $$.length - 1;

feature: added `%include \` support where you include any JavaScript code instead of dumping it into the lexer/grammar file itself; see the `examples/precedence.jison` file for a *minimal demo* of its potential uses -- particularly handy when certain actions, surplus/trailing code chunks and/or `%{...%}` code preludes have become pretty huge as you use JISON for a (complex) production grammar. - minor cleanup: several `yytext` uses in the *grammars* have been replaced by their preferred way of coding such references, i.e. using the `$`-prefixed rule atom name as a reference instead. **TBD**: the code is still littered with debug statements as we had a hard time finding one lexer issue -- see also lexer commit https://github.com/GerHobbelt/lex-parser/commit/34386d2e20c6e39f27c36d90ad6796c2fc3b803f#diff-59204921b9c3a0d61b7272c7bce37df1R49 --- bnf.l | 21 +- bnf.y | 67 +- ebnf-parser.js | 5 +- parser.js | 1767 ++++++++++++++++++++++++++++-------------------- 4 files changed, 1126 insertions(+), 734 deletions(-) diff --git a/bnf.l b/bnf.l index 1230a94..0fc7cbf 100644 --- a/bnf.l +++ b/bnf.l @@ -4,7 +4,7 @@ hex_number "0"[xX][0-9a-fA-F]+ BR \r\n|\n|\r -%x action code +%x action code path %s token %s bnf ebnf @@ -49,9 +49,12 @@ BR \r\n|\n|\r "%parse-param" return 'PARSE_PARAM'; "%options" return 'OPTIONS'; "%lex"[\w\W]*?{BR}\s*"/lex"\b return 'LEX_BLOCK'; + +"%include" this.pushState('path'); return 'INCLUDE'; + "%"{id}[^\r\n]* %{ /* ignore unrecognized decl */ -

lexer rule, or we won't be able to use it for things like keyword-ing lexer rules like `"%options"` (due to that `%` in there) - reverted and updated: 'easy keyword rules' option now accepts lexer rules which carry a keyword with any non-keyword prefix - 'easy keyword rules' option now accepts Unicode/hex/octal escapes as part of a 'keyword' as long as these produce a 'alphanumeric' character i.e. part of the keyword - 'easy keyword rules' option now accepts Unicode literals as part of a 'keyword' as long as these are 'alphanumeric' characters i.e. part of the keyword --- bnf.l | 2 +- 1

This is *not* the look-ahead token, but the last token + * that's actually part of this rule. + * + * Formulated another way, `yytext` is the value of the token immediately preceeding + * the current look-ahead token. + * Caveats apply for rules which don't require look-ahead, such as epsilon rules. + * + * - `yyleng` : ditto as `yytext`, only now for the lexer.yyleng value. + * + * - `yylineno`: ditto as `yytext`, only now for the lexer.yylineno value. + * + * - `yyloc` : ditto as `yytext`, only now for the lexer.yylloc lexer token location info. + * + * - `yystate` : the current parser state number, used internally for dispatching and + * executing the action code chunk matching the rule currently being reduced. + * + * - `yysp` : the current state stack position (a.k.a.

This same bug exists in JISON itself and is being fixed there as well. The way to observe this bug and make it cause undesired behaviour is using a rule where the implicit alias numbers would be 11 or greater, e.g. a rule like `a1 a1 a1 a1 a1 a1 a1 a1 a1 a1 a1 a11` which would otherwise be implicitly aliased as `a1[a11] a1[a12] a1[a13] a1[a14] a1[a15] a1[a16] a1[a17] a1[a18] a1[a19] a1[a110] a1[a111] a11[a111]`: note the undesirable clash between implicit alias `a11` which will block the direct term `a11` and thus produce incorrect action code when `$a11` is used in the action code. Now any term or alias with a number tail is properly marked up as blocking any creation of implicit aliases of the same base name. See also the comment chunk in the JISON.JS file, where this same logic originates as we have to duplicate that bit for the EBNF to BNF rewrite logic in this library: ``` var count = {}, names = {}, donotalias = {}; // When the rule is fitted with aliases it doesn't mean that the action code MUST use those: // we therefor allow access to both the original (non)terminal and the alias. // // Also note that each (non)terminal can also be uniquely addressed by [$@] // where N is a number representing the number of this particular occurrence of the given // (non)terminal. // // For example, given this (intentionally contrived) production: // elem[alias] elem[another_alias] another_elem[alias] elem[alias] another_elem[another_alias] // all the items can be accessed as: // $1 $2 $3 $4 $5 // $elem1 $elem2 $another_elem1 $elem3 $another_elem2 // $elem $elem2 $another_elem $elem3 $another_elem2 // $alias1 $another_alias1 $alias2 $alias3 $another_alias2 // $alias $another_alias $alias2 $alias3 $another_alias2 // where each line above is equivalent to the top-most line. Note the numbers postfixed to // both (non)terminal identifiers and aliases alike and also note alias2 === another_elem1: // the postfix numbering is independent. // // WARNING: this feature is disabled for a term when there already exists an // (human-defined) *alias* for this term *or* when the numbered auto-alias already // exists because the user has used it as an alias for another term, e.g. // // e: WORD[e1] '=' e '+' e; // // would *not* produce the `e1` and `e2` aliases, as `e1` is already defined // as an explicit alias: adding auto-alias `e1` would then break the system, // while `e2` would be ambiguous from the human perspective as he *might* then // expect `e2` and `e3`. var addName = function addName(s) { var base = s.replace(/[0-9]+$/, ''); var dna = donotalias[base]; if (names[s]) { count[s]++; if (!dna) { names[s + count[s]] = i + 1; } } else { names[s] = i + 1; count[s] = 1; if (!dna) { names[s + count[s]] = i + 1; } } }; // register the alias/rule name when the real one ends with a number, e.g. `rule5` as // *blocking* the auto-aliasing process for the term of the same base, e.g. `rule`. // This will catch the `WORD[e1]` example above too, via `e1` --> `donotalias['e']` var markBasename = function markBasename(s) { if (/[0-9]$/.test(s)) { s = s.replace(/[0-9]+$/, ''); donotalias[s] = true; } }; for (i = 0; i < rhs.length; i++) { // mark both regular and aliased names, e.g., `id[alias1]` and `id1` rhs_i = aliased[i]; markBasename(rhs_i); if (rhs_i !== rhs[i]) { markBasename(rhs[i]); } } for (i = 0; i < rhs.length; i++) { // check for aliased names, e.g., id[alias] rhs_i = aliased[i]; addName(rhs_i); if (rhs_i !== rhs[i]) { addName(rhs[i]); } } ``` --- ebnf-transform.js | 111 +++++++++++++++++++++++++++++++++------------- 1 file changed, 81 insertions(+), 30 deletions(-) diff --git a/ebnf-transform.js b/ebnf-transform.js index 7f37747..1a9014c 100644 --- a/ebnf-transform.js +++ b/ebnf-transform.js @@ -1,4 +1,4 @@ -var EBNF = (function(){ +var EBNF = (function () { var parser = require('./transform-parser.js'); var XRegExp = require('xregexp'); //var assert = require('assert'); @@ -22,7 +22,7 @@ var EBNF = (function(){ return rv; } -
