5 * Returns a Parser object of the following structure:
6 *
7 * Parser: {
8 * yy: {} The so-called "shared state" or rather the *source* of it;
9 * the real "shared state" `yy` passed around to
10 * the rule actions, etc. is a derivative/copy of this one,
11 * not a direct reference!
12 * }
13 *
14 * Parser.prototype: {
15 * yy: {},
16 * EOF: 1,
17 * TERROR: 2,
18 *
19 * trace: function(errorMessage, ...),
20 *
21 * JisonParserError: function(msg, hash),
22 *
23 * quoteName: function(name),
24 * Helper function which can be overridden by user code later on: put suitable
25 * quotes around literal IDs in a description string.
26 *
27 * originalQuoteName: function(name),
28 * The basic quoteName handler provided by JISON.
29 * `cleanupAfterParse()` will clean up and reset `quoteName()` to reference this function
30 * at the end of the `parse()`.
31 *
32 * describeSymbol: function(symbol),
33 * Return a more-or-less human-readable description of the given symbol, when
34 * available, or the symbol itself, serving as its own 'description' for lack
35 * of something better to serve up.
36 *
37 * Return NULL when the symbol is unknown to the parser.
38 *
39 * symbols_: {associative list: name ==> number},
40 * terminals_: {associative list: number ==> name},
41 * nonterminals: {associative list: rule-name ==> {associative list: number ==> rule-alt}},
42 * terminal_descriptions_: (if there are any) {associative list: number ==> description},
43 * productions_: [...],
44 *
45 * performAction: function parser__performAction(yytext, yyleng, yylineno, yyloc, yystate, yysp, yyvstack, yylstack, yystack, yysstack),
46 *
47 * The function parameters and `this` have the following value/meaning:
48 * - `this` : reference to the `yyval` internal object, which has members (`$` and `_$`)
49 * to store/reference the rule value `$$` and location info `@$`.
50 *
51 * One important thing to note about `this` a.k.a. `yyval`: every *reduce* action gets
52 * to see the same object via the `this` reference, i.e. if you wish to carry custom
53 * data from one reduce action through to the next within a single parse run, then you
54 * may get nasty and use `yyval` a.k.a. `this` for storing you own semi-permanent data.
55 *
56 * `this.yy` is a direct reference to the `yy` shared state object.
57 *
58 * `%parse-param`-specified additional `parse()` arguments have been added to this `yy`
59 * object at `parse()` start and are therefore available to the action code via the
60 * same named `yy.xxxx` attributes (where `xxxx` represents a identifier name from
61 * the %parse-param` list.
62 *
63 * - `yytext` : reference to the lexer value which belongs to the last lexer token used
64 * to match this rule. This is *not* the look-ahead token, but the last token
65 * that's actually part of this rule.
66 *
67 * Formulated another way, `yytext` is the value of the token immediately preceeding
68 * the current look-ahead token.
69 * Caveats apply for rules which don't require look-ahead, such as epsilon rules.
70 *
71 * - `yyleng` : ditto as `yytext`, only now for the lexer.yyleng value.
72 *
73 * - `yylineno`: ditto as `yytext`, only now for the lexer.yylineno value.
74 *
75 * - `yyloc` : ditto as `yytext`, only now for the lexer.yylloc lexer token location info.
76 *
77 * WARNING: since jison 0.4.18-186 this entry may be NULL/UNDEFINED instead
78 * of an empty object when no suitable location info can be provided.
79 *
80 * - `yystate` : the current parser state number, used internally for dispatching and
81 * executing the action code chunk matching the rule currently being reduced.
82 *
83 * - `yysp` : the current state stack position (a.k.a. 'stack pointer')
84 *
85 * This one comes in handy when you are going to do advanced things to the parser
86 * stacks, all of which are accessible from your action code (see the next entries below).
87 *
88 * Also note that you can access this and other stack index values using the new double-hash
89 * syntax, i.e. `##$ === ##0 === yysp`, while `##1` is the stack index for all things
90 * related to the first rule term, just like you have `$1`, `@1` and `#1`.
91 * This is made available to write very advanced grammar action rules, e.g. when you want
92 * to investigate the parse state stack in your action code, which would, for example,
93 * be relevant when you wish to implement error diagnostics and reporting schemes similar
94 * to the work described here:
95 *
96 * + Pottier, F., 2016. Reachability and error diagnosis in LR(1) automata.
97 * In Journées Francophones des Languages Applicatifs.
98 *
99 * + Jeffery, C.L., 2003. Generating LR syntax error messages from examples.
100 * ACM Transactions on Programming Languages and Systems (TOPLAS), 25(5), pp.631–640.
101 *
102 * - `yyrulelength`: the current rule's term count, i.e. the number of entries occupied on the stack.
103 *
104 * This one comes in handy when you are going to do advanced things to the parser
105 * stacks, all of which are accessible from your action code (see the next entries below).
106 *
107 * - `yyvstack`: reference to the parser value stack. Also accessed via the `$1` etc.
108 * constructs.
109 *
110 * - `yylstack`: reference to the parser token location stack. Also accessed via
111 * the `@1` etc. constructs.
112 *
113 * WARNING: since jison 0.4.18-186 this array MAY contain slots which are
114 * UNDEFINED rather than an empty (location) object, when the lexer/parser
115 * action code did not provide a suitable location info object when such a
116 * slot was filled!
117 *
118 * - `yystack` : reference to the parser token id stack. Also accessed via the
119 * `#1` etc. constructs.
120 *
121 * Note: this is a bit of a **white lie** as we can statically decode any `#n` reference to
122 * its numeric token id value, hence that code wouldn't need the `yystack` but *you* might
123 * want access this array for your own purposes, such as error analysis as mentioned above!
124 *
125 * Note that this stack stores the current stack of *tokens*, that is the sequence of
126 * already parsed=reduced *nonterminals* (tokens representing rules) and *terminals*
127 * (lexer tokens *shifted* onto the stack until the rule they belong to is found and
128 * *reduced*.
129 *
130 * - `yysstack`: reference to the parser state stack. This one carries the internal parser
131 * *states* such as the one in `yystate`, which are used to represent
132 * the parser state machine in the *parse table*. *Very* *internal* stuff,
133 * what can I say? If you access this one, you're clearly doing wicked things
134 *
135 * - `...` : the extra arguments you specified in the `%parse-param` statement in your
136 * grammar definition file.
137 *
138 * table: [...],
139 * State transition table
140 * ----------------------
141 *
142 * index levels are:
143 * - `state` --> hash table
144 * - `symbol` --> action (number or array)
145 *
146 * If the `action` is an array, these are the elements' meaning:
147 * - index [0]: 1 = shift, 2 = reduce, 3 = accept
148 * - index [1]: GOTO `state`
149 *
150 * If the `action` is a number, it is the GOTO `state`
151 *
152 * defaultActions: {...},
153 *
154 * parseError: function(str, hash, ExceptionClass),
155 * yyError: function(str, ...),
156 * yyRecovering: function(),
157 * yyErrOk: function(),
158 * yyClearIn: function(),
159 *
160 * constructParseErrorInfo: function(error_message, exception_object, expected_token_set, is_recoverable),
161 * Helper function **which will be set up during the first invocation of the `parse()` method**.
162 * Produces a new errorInfo 'hash object' which can be passed into `parseError()`.
163 * See it's use in this parser kernel in many places; example usage:
164 *
165 * var infoObj = parser.constructParseErrorInfo('fail!', null,
166 * parser.collect_expected_token_set(state), true);
167 * var retVal = parser.parseError(infoObj.errStr, infoObj, parser.JisonParserError);
168 *
169 * originalParseError: function(str, hash, ExceptionClass),
170 * The basic `parseError` handler provided by JISON.
171 * `cleanupAfterParse()` will clean up and reset `parseError()` to reference this function
172 * at the end of the `parse()`.
173 *
174 * options: { ... parser %options ... },
175 *
176 * parse: function(input[, args...]),
177 * Parse the given `input` and return the parsed value (or `true` when none was provided by
178 * the root action, in which case the parser is acting as a *matcher*).
179 * You MAY use the additional `args...` parameters as per `%parse-param` spec of this grammar:
180 * these extra `args...` are added verbatim to the `yy` object reference as member variables.
181 *
182 * WARNING:
183 * Parser's additional `args...` parameters (via `%parse-param`) MAY conflict with
184 * any attributes already added to `yy` by the jison run-time;
185 * when such a collision is detected an exception is thrown to prevent the generated run-time
186 * from silently accepting this confusing and potentially hazardous situation!
187 *
188 * The lexer MAY add its own set of additional parameters (via the `%parse-param` line in
189 * the lexer section of the grammar spec): these will be inserted in the `yy` shared state
190 * object and any collision with those will be reported by the lexer via a thrown exception.
191 *
192 * cleanupAfterParse: function(resultValue, invoke_post_methods, do_not_nuke_errorinfos),
193 * Helper function **which will be set up during the first invocation of the `parse()` method**.
194 * This helper API is invoked at the end of the `parse()` call, unless an exception was thrown
195 * and `%options no-try-catch` has been defined for this grammar: in that case this helper MAY
196 * be invoked by calling user code to ensure the `post_parse` callbacks are invoked and
197 * the internal parser gets properly garbage collected under these particular circumstances.
198 *
199 * yyMergeLocationInfo: function(first_index, last_index, first_yylloc, last_yylloc, dont_look_back),
200 * Helper function **which will be set up during the first invocation of the `parse()` method**.
201 * This helper API can be invoked to calculate a spanning `yylloc` location info object.
202 *
203 * Note: %epsilon rules MAY specify no `first_index` and `first_yylloc`, in which case
204 * this function will attempt to obtain a suitable location marker by inspecting the location stack
205 * backwards.
206 *
207 * For more info see the documentation comment further below, immediately above this function's
208 * implementation.
209 *

256 *
257 * The `parseError` function receives a 'hash' object with these members for lexer and
258 * parser errors:
259 *
260 * {
261 * text: (matched text)
262 * token: (the produced terminal token, if any)
263 * token_id: (the produced terminal token numeric ID, if any)
264 * line: (yylineno)
265 * loc: (yylloc)
266 * }
267 *
268 * parser (grammar) errors will also provide these additional members:
269 *
270 * {
271 * expected: (array describing the set of expected tokens;
272 * may be UNDEFINED when we cannot easily produce such a set)
273 * state: (integer (or array when the table includes grammar collisions);
274 * represents the current internal state of the parser kernel.
275 * can, for example, be used to pass to the `collect_expected_token_set()`
276 * API to obtain the expected token set)
277 * action: (integer; represents the current internal action which will be executed)
278 * new_state: (integer; represents the next/planned internal state, once the current
279 * action has executed)
280 * recoverable: (boolean: TRUE when the parser MAY have an error recovery rule
281 * available for this particular error)
282 * state_stack: (array: the current parser LALR/LR internal state stack; this can be used,
283 * for instance, for advanced error analysis and reporting)
284 * value_stack: (array: the current parser LALR/LR internal `$$` value stack; this can be used,
285 * for instance, for advanced error analysis and reporting)
286 * location_stack: (array: the current parser LALR/LR internal location stack; this can be used,
287 * for instance, for advanced error analysis and reporting)
288 * yy: (object: the current parser internal "shared state" `yy`
289 * as is also available in the rule actions; this can be used,
290 * for instance, for advanced error analysis and reporting)
291 * lexer: (reference to the current lexer instance used by the parser)
292 * parser: (reference to the current parser instance)
293 * }
294 *
295 * while `this` will reference the current parser instance.
296 *
297 * When `parseError` is invoked by the lexer, `this` will still reference the related *parser*
298 * instance, while these additional `hash` fields will also be provided:
299 *
300 * {
301 * lexer: (reference to the current lexer instance which reported the error)
302 * }
303 *
304 * When `parseError` is invoked by the parser due to a **JavaScript exception** being fired
305 * from either the parser or lexer, `this` will still reference the related *parser*
306 * instance, while these additional `hash` fields will also be provided:
307 *
308 * {
309 * exception: (reference to the exception thrown)
310 * }
311 *
312 * Please do note that in the latter situation, the `expected` field will be omitted as
313 * this type of failure is assumed not to be due to *parse errors* but rather due to user
314 * action code in either parser or lexer failing unexpectedly.
315 *
316 * ---
317 *
318 * You can specify parser options by setting / modifying the `.yy` object of your Parser instance.
319 * These options are available:
320 *
321 * ### options which are global for all parser instances
322 *
323 * Parser.pre_parse: function(yy)
324 * optional: you can specify a pre_parse() function in the chunk following
325 * the grammar, i.e. after the last `%%`.
326 * Parser.post_parse: function(yy, retval, parseInfo) { return retval; }
327 * optional: you can specify a post_parse() function in the chunk following
328 * the grammar, i.e. after the last `%%`. When it does not return any value,
329 * the parser will return the original `retval`.
330 *
331 * ### options which can be set up per parser instance
332 *
333 * yy: {
334 * pre_parse: function(yy)
335 * optional: is invoked before the parse cycle starts (and before the first
336 * invocation of `lex()`) but immediately after the invocation of
337 * `parser.pre_parse()`).
338 * post_parse: function(yy, retval, parseInfo) { return retval; }
339 * optional: is invoked when the parse terminates due to success ('accept')
340 * or failure (even when exceptions are thrown).
341 * `retval` contains the return value to be produced by `Parser.parse()`;
342 * this function can override the return value by returning another.
343 * When it does not return any value, the parser will return the original
344 * `retval`.
345 * This function is invoked immediately before `parser.post_parse()`.
346 *
347 * parseError: function(str, hash, ExceptionClass)
348 * optional: overrides the default `parseError` function.
349 * quoteName: function(name),
350 * optional: overrides the default `quoteName` function.
351 * }
352 *
353 * parser.lexer.options: {
354 * pre_lex: function()
355 * optional: is invoked before the lexer is invoked to produce another token.
356 * `this` refers to the Lexer object.
357 * post_lex: function(token) { return token; }
358 * optional: is invoked when the lexer has produced a token `token`;
359 * this function can override the returned token value by returning another.
360 * When it does not return any (truthy) value, the lexer will return
361 * the original `token`.
362 * `this` refers to the Lexer object.
363 *
364 * ranges: boolean
365 * optional: `true` ==> token location info will include a .range[] member.
366 * flex: boolean
367 * optional: `true` ==> flex-like lexing behaviour where the rules are tested
368 * exhaustively to find the longest match.
369 * backtrack_lexer: boolean
370 * optional: `true` ==> lexer regexes are tested in order and for invoked;
371 * the lexer terminates the scan when a token is returned by the action code.
372 * xregexp: boolean
373 * optional: `true` ==> lexer rule regexes are "extended regex format" requiring the
374 * `XRegExp` library. When this `%option` has not been specified at compile time, all lexer
375 * rule regexes have been written as standard JavaScript RegExp expressions.
376 * }

1894 *
1895 * This "shared context" object was passed to the lexer by way of
1896 * the `lexer.setInput(str, yy)` API before you may use it.
1897 *
1898 * This "shared context" object is passed to the lexer action code in `performAction()`
1899 * so userland code in the lexer actions may communicate with the outside world
1900 * and/or other lexer rules' actions in more or less complex ways.

1914 * The function parameters and `this` have the following value/meaning:
1915 * - `this` : reference to the `lexer` instance.
1916 * `yy_` is an alias for `this` lexer instance reference used internally.
1917 *
1918 * - `yy` : a reference to the `yy` "shared state" object which was passed to the lexer
1919 * by way of the `lexer.setInput(str, yy)` API before.
1920 *
1921 * Note:
1922 * The extra arguments you specified in the `%parse-param` statement in your
1923 * **parser** grammar definition file are passed to the lexer via this object
1924 * reference as member variables.
1925 *
1926 * - `yyrulenumber` : index of the matched lexer rule (regex), used internally.
1927 *

1936 *
1937 * var infoObj = lexer.constructParseErrorInfo('fail!', true);

1945 * these extra `args...` are added verbatim to the `yy` object reference as member variables.
1946 *
1947 * WARNING:
1948 * Lexer's additional `args...` parameters (via lexer's `%parse-param`) MAY conflict with
1949 * any attributes already added to `yy` by the **parser** or the jison run-time;
1950 * when such a collision is detected an exception is thrown to prevent the generated run-time
1951 * from silently accepting this confusing and potentially hazardous situation!
1952 *
1953 * cleanupAfterLex: function(do_not_nuke_errorinfos),
1954 * Helper function.

2033 * The `parseError` function receives a 'hash' object with these members for lexer errors:
2034 *
2035 * {
2036 * text: (matched text)
2037 * token: (the produced terminal token, if any)
2038 * token_id: (the produced terminal token numeric ID, if any)
2039 * line: (yylineno)
2040 * loc: (yylloc)
2041 * recoverable: (boolean: TRUE when the parser MAY have an error recovery rule
2042 * available for this particular error)
2043 * yy: (object: the current parser internal "shared state" `yy`
2044 * as is also available in the rule actions; this can be used,
2045 * for instance, for advanced error analysis and reporting)
2046 * lexer: (reference to the current lexer instance used by the parser)
2047 * }
2048 *
2049 * while `this` will reference the current lexer instance.
2050 *
2051 * When `parseError` is invoked by the lexer, the default implementation will
2052 * attempt to invoke `yy.parser.parseError()`; when this callback is not provided
2053 * it will try to invoke `yy.parseError()` instead. When that callback is also not
2054 * provided, a `JisonLexerError` exception will be thrown containing the error
2055 * message and `hash`, as constructed by the `constructLexErrorInfo()` API.
2056 *
2057 * Note that the lexer's `JisonLexerError` error class is passed via the
2058 * `ExceptionClass` argument, which is invoked to construct the exception
2059 * instance to be thrown, so technically `parseError` will throw the object
2060 * produced by the `new ExceptionClass(str, hash)` JavaScript expression.
2061 *
2062 * ---
2063 *
2064 * You can specify lexer options by setting / modifying the `.options` object of your Lexer instance.
2065 * These options are available:
2066 *
2067 * (Options are permanent.)
2068 *
2069 * yy: {
2070 * parseError: function(str, hash, ExceptionClass)
2071 * optional: overrides the default `parseError` function.
2072 * }
2073 *
2074 * lexer.options: {
2075 * pre_lex: function()
2076 * optional: is invoked before the lexer is invoked to produce another token.
2077 * `this` refers to the Lexer object.
2078 * post_lex: function(token) { return token; }
2079 * optional: is invoked when the lexer has produced a token `token`;
2080 * this function can override the returned token value by returning another.
2081 * When it does not return any (truthy) value, the lexer will return
2082 * the original `token`.
2083 * `this` refers to the Lexer object.
2084 *
2085 * WARNING: the next set of options are not meant to be changed. They echo the abilities of
2086 * the lexer as per when it was compiled!
2087 *
2088 * ranges: boolean
2089 * optional: `true` ==> token location info will include a .range[] member.
2090 * flex: boolean
2091 * optional: `true` ==> flex-like lexing behaviour where the rules are tested
2092 * exhaustively to find the longest match.
2093 * backtrack_lexer: boolean
2094 * optional: `true` ==> lexer regexes are tested in order and for invoked;
2095 * the lexer terminates the scan when a token is returned by the action code.
2096 * xregexp: boolean
2097 * optional: `true` ==> lexer rule regexes are "extended regex format" requiring the
2098 * `XRegExp` library. When this %option has not been specified at compile time, all lexer
2099 * rule regexes have been written as standard JavaScript RegExp expressions.

2526 * - `cpsArg` is `cpsArg` passed into this API.

2528 * The `this` reference for the callback will be set to
2529 * reference this lexer instance so that userland code
2530 * in the callback can easily and quickly access any lexer
2531 * API.
2532 *
2533 * When the callback returns a non-string-type falsey value,
2534 * we assume the callback did not edit the input and we
2535 * will using the input as-is.
2536 *
2537 * When the callback returns a non-string-type value, it
2538 * is converted to a string for lexing via the `"" + retval`
2539 * operation. (See also why: http://2ality.com/2012/03/converting-to-string.html

2948 * This function pretty-prints the indicated section of the input, with line numbers
2949 * and everything!
2950 *
2951 * This function is very useful to provide highly readable error reports, while
2952 * the location range may be specified in various flexible ways:
2953 *
2954 * - `loc` is the location info object which references the area which should be
2955 * displayed and 'marked up': these lines & columns of text are marked up by `^`
2956 * characters below each character in the entire input range.
2957 *
2958 * - `context_loc` is the *optional* location info object which instructs this
2959 * pretty-printer how much *leading* context should be displayed alongside
2960 * the area referenced by `loc`. This can help provide context for the displayed
2961 * error, etc.
2962 *
2963 * When this location info is not provided, a default context of 3 lines is
2964 * used.
2965 *
2966 * - `context_loc2` is another *optional* location info object, which serves
2967 * a similar purpose to `context_loc`: it specifies the amount of *trailing*
2968 * context lines to display in the pretty-print output.
2969 *
2970 * When this location info is not provided, a default context of 1 line only is
2971 * used.
2972 *
2973 * Special Notes:
2974 *
2975 * - when the `loc`-indicated range is very large (about 5 lines or more), then
2976 * only the first and last few lines of this block are printed while a
2977 * `...continued...` message will be printed between them.
2978 *
2979 * This serves the purpose of not printing a huge amount of text when the `loc`
2980 * range happens to be huge: this way a manageable & readable output results
2981 * for arbitrary large ranges.
2982 *
2983 * - this function can display lines of input which whave not yet been lexed.
2984 * `prettyPrintRange()` can access the entire input!
