/*
* The English command grammar. These rules define the overall sentence
* syntax its various components.
*
* We start parsing a new command at firstCommandPhrase (for the first
* command on a line) or commandPhrase (for the second and subsequent
* commands on the same line). The difference between the two is that
* firstCommandPhrase accepts actor orders (BOB, GO NORTH or TELL BOB TO
* OPEN DOOR), while commandPhrase doesn't.
*
* Other language modules are NOT required to duplicate the English
* grammar tree rule-for-rule. You must only define the rules marked
* with [Required], since these are referenced from the base library
* parser. The [Required] grammar objects must exist and use the given
* base names, but the number of rules for a given grammar, the tag
* names, and the syntax defined within the rules are all up to the
* language module.
*
* Rules NOT marked [Required] are internal to the English grammar:
* they're only referenced from other parts of the English grammar, so
* they're not required to exist in other languages. A language module
* is free to use its own completely different structure for the internal
* rules, and should - the structure should be based on the natural
* grammar of the implemented language, not on how the English rules here
* are structured.
*
* Note that the base library provides a number of XxxProduction classes
* for structural elements that should be common to most or all languages
* - NounPhraseProduction, PossessiveProduction, PronounProduction, etc.
* As a language implementer, you're NOT required to implement any
* grammar rules based on any of these classes. But you'll probably want
* to anyway, because these classes are designed to make your life a lot
* easier by doing most of the work for you. These classes provide code
* that translates the information in the syntax tree into the
* corresponding semantic information in the parser. If you don't create
* rules based on these classes, you'll have to instead write your own
* code in the rules that propagates the required information into the
* parser parser. The XxxProduction classes are designed to be abstract
* and language-independent, so if the base library does its job
* correctly, it should be straightforward to use these classes at the
* appropriate points in the grammar.

/*
* Verb grammar (predicate) rules for English.
*
* English's predicate syntax is highly positional. That is, the role of
* each word in a predicate is determined largely by its position in the
* phrase. There are a several common patterns to the predicate word
* order, but the specific pattern that applies to a given verb is
* essentially idiomatic to that verb, especially with respect to
* complement words (like the "up" in "pick up"). Our approach to
* defining the predicate grammar is therefore to define a separate,
* custom syntax rule for each verb. This makes it easy to add rules for
* the odd little idioms in English verbs.
*
* For verbs that take indirect objects, the indirect object is usually
* introduced by a preposition (e.g., PUT KEY IN LOCK). Since we
* consider the preposition in such a case to be part of the verb's
* grammatical structure, we write it directly into the grammar rule as a
* literal. This means that we wouldn't be able to parse input that's
* missing the whole indirect object phrase (e.g., PUT KEY). We don't
* want to just reject those without explanation, though, which means we
* have to define separate grammar rules for the truncated verbs. Some
* of these cases are valid commands in their own right: UNLOCK DOOR and
* UNLOCK DOOR WITH KEY are both valid grammatically. But PUT KEY isn't,
* so we need to mark this as missing its indirect object. We do this by
* setting the missingRole property for these rules to the role (usually
* IndirectObject) of the phrase that's missing.
*
* Each VerbRule has several properties and methods that it can or must
* define:
*
* action [Required] - The associated Action that's executed when this
* verb is parsed. The base library requires this property.
*
* verbPhrase - The message-building template for the verb. The library
* uses this to construct messages to describe the associated action.
* The format is 'verb/verbing (dobj) (iobj) (accessory)'. Each object
* role in parentheses consists of an optional preposition and the word
* 'what' or 'whom'. For example, 'ask/asking (whom) (about what)'.
* Outside of the parentheses, you can also include verb complement words
* before the first object or after the last, but never between objects:
* for example, 'pick/picking up (what)'.
*
* missingQ - the template for asking missing object questions. This
* consists of one question per object, separated by semicolons, in the
* order dobj, iobj, accessory. You only need as many questions as the
* verb has object slots (i.e., you only need an iobj question if the
* verb takes an indirect object). The question is simply of the form
* "what do you want to <verb>", but you can also include the words "it"
* and "that" to refer to the "other" object(s) in the verb. "It" will
* be replaced by it/him/her/them as appropriate, and "that" by
* that/them. Use it-dobj, it-iobj, it-acc to specify which other object
* you're talking about (which is never necessary for two-object verbs,
* since there's only one other object). Put the entire 'it' phrase,
* including prepositions, in parentheses to make it optional; it will be
* omitted if the object isn't part of the command input. This is only
* necessary for objects appearing earlier in the verb rule, since it's
* resolved left to right.
*
* missingRole - the object role (DirectObject, etc) that's explicitly
* missing from this grammar syntax. This is for rules that you define
* specifically to recognize partial input, like "PUT <dobj>". The
* parser will ask for the missing object when it resolves such a rule.
*
* answerMissing(cmd, np) - the base library calls this when the player
* answers the parser's question asking for the missing noun phrase.
* 'cmd' is the Command, and 'np' is the noun phrase parsed from the
* user's answer to the query. This is called from the base library but
* isn't required, in that it's purely advisory. The point of this
* routine is to let the verb change the command according to the reply.
* For example, in English, we have a generic Put <dobj> verb that asks
* where to put the dobj. If the user says "in the box", we can change
* the action to Put In; if the user says "on the table", we can change
* the action to Put On.
*
* dobjReply, iobjReply, accReply - the noun phrase production to use for
* parsing a reply to the missing-object question for the corresponding
* role. Players sometimes reply to a question like "What do you want to
* put it in?" by starting the answer with the same preposition in the
* question: "in the box". To support this, you can specify a noun
* phrase production that starts with the appropriate preposition
* (inSingleNoun, onSingleNoun, etc).
*
* (Note that the base library doesn't place any requirements on exactly
* how the verb rules are defined. In particular, you don't have to
* define one rule per verb, the way we do in English. The English
* module's one-verb/one-rule approach might not be a good fit when
* implementing a highly inflected language, since such languages are
* typically a lot more flexible about word order, creating a wide range
* of possible phrasings for each verb. It might be easier to for such a
* language to define a set of universal verb grammar rules that cover
* the common structures for all verbs, and then define the individual
* verbs as simple vocabulary words that slot into this universal phrase
* structure.)

* Additional English grammar properties.
*
* For each Action, we set up the property grammarTemplates with a list
* of all of the possible command input syntax templates that can be used
* to generate the action from a user command. These are of the form
* "put (dobj) in (iobj)", which we can easily use to generate messages
* or compare to input phrases. This is sometimes useful for determining
* the specific phrasing the player used in input, when a given action
* has multiple possible phrasings.
*
* For each VerbProduction (which is generally the same as a VerbRule
* definition), we set the property grammarAlts to a list of the grammar
* rules for the verb. This is useful for finding the specific rule we
* matched for a given parsed input.
*
* These lists, and the procedure for building them, are inherently
* specific to the English library. Other languages might not define
* their verb grammars with the same structures, so the assumptions we
* make about the grammar trees might not hold in all languages. These
* lists are only used within the English part of the library, since the
* generic library can't count on them being available in other
* translations.

/*
* Initialize the DoerParser table. This populates the given
* DoerParserTable with DoerParser objects that describe the syntax
* available for use in Doer 'cmd' strings.
*
* Each DoerParser object simply provides a regular expression for
* parsing one action phrasing. The regular expression defines the
* language-specific template for the action phrasing, with the proviso
* that each noun phrase is replaced with an object or class name, or a
* list of object or class names separated with '|' characters.
*
* For example, for a Give To command in English, we might define one
* DoerParser for each of the following regular expressions:
*
*. 'give (<alphanum|_|vbar>+) to (<alphanum|_|vbar>+)'
*. 'give (<alphanum|_|vbar>+) (<alphanum|_|vbar>+)'
*
* After you create a DoerParser, simply call ptab.addParser() to add the
* new parser to the table.
*
* Note that, regardless of the language, you MUST use a verb syntax that
* starts with a verb word, because of the way the parser lookup table is
* built. Most languages naturally start an imperative with a verb
* anyway, so this is usually what you'd do even without this
* requirement. For a language that uses another word order for
* imperatives, though, you'll have to use an unnatural syntax for the
* DoerParser syntax, and thus for the Doer 'cmd' string syntax. This
* unnatural syntax is purely internal to the library and games, though -
* players won't see it.
*
* It's up to the language module to determine how to come up with the
* list of verb phrases, and how to build the verb regular expression
* patterns. The English library builds the list directly from the
* player command grammar - specifically, the syntax token lists defined
* for the VerbRule productions.
*
* This English implementation also takes the opportunity to build
* grammar templates for each Action. This is purely for our own use in
* the English library, so other languages don't have to replicate that
* functionality. We do this here because we build these from the same
* information that we use to build the DoerParsers.
