Currently, this serves to + * limit the functions which can be used in text mode. + * + * The main functions then return an object which contains the useful data that + * was parsed at its given point, and a new position at the end of the parsed + * data. The main functions can call each other and continue the parsing by + * using the returned position as a new starting point. + * + * There are also extra `.handle...` functions, which pull out some reused + * functionality into self-contained functions. + * + * The earlier functions return ParseNodes. + * The later functions (which are called deeper in the parse) sometimes return + * ParseFuncOrArgument, which contain a ParseNode as well as some data about + * whether the parsed object is a function which is missing some arguments, or a + * standalone object which can be used as an argument to another function. + */ + +/** + * Main Parser class + */ +function Parser(input, settings) { + // Create a new macro expander (gullet) and (indirectly via that) also a + // new lexer (mouth) for this parser (stomach, in the language of TeX) + this.gullet = new MacroExpander(input, settings.macros); + // Store the settings for use in parsing + this.settings = settings; +} + +var ParseNode = parseData.ParseNode; + +/** + * An initial function (without its arguments), or an argument to a function. + * The `result` argument should be a ParseNode. + */ +function ParseFuncOrArgument(result, isFunction, token) { + this.result = result; + // Is this a function (i.e. is it something defined in functions.js)? + this.isFunction = isFunction; + this.token = token; +} + +/** + * Checks a result to make sure it has the right type, and throws an + * appropriate error otherwise. + * + * @param {boolean=} consume whether to consume the expected token, + * defaults to true + */ +Parser.prototype.expect = function(text, consume) { + if (this.nextToken.text !== text) { + throw new ParseError( + "Expected '" + text + "', got '" + this.nextToken.text + "'", + this.nextToken + ); + } + if (consume !== false) { + this.consume(); + } +}; + +/** + * Considers the current look ahead token as consumed, + * and fetches the one after that as the new look ahead. + */ +Parser.prototype.consume = function() { + this.nextToken = this.gullet.get(this.mode === "math"); +}; + +Parser.prototype.switchMode = function(newMode) { + this.gullet.unget(this.nextToken); + this.mode = newMode; + this.consume(); +}; + +/** + * Main parsing function, which parses an entire input. + * + * @return {?Array.} + */ +Parser.prototype.parse = function() { + // Try to parse the input + this.mode = "math"; + this.consume(); + var parse = this.parseInput(); + return parse; +}; + +/** + * Parses an entire input tree. + */ +Parser.prototype.parseInput = function() { + // Parse an expression + var expression = this.parseExpression(false); + // If we succeeded, make sure there's an EOF at the end + this.expect("EOF", false); + return expression; +}; + +var endOfExpression = ["}", "\\end", "\\right", "&", "\\\\", "\\cr"]; + +/** + * Parses an "expression", which is a list of atoms. + * + * @param {boolean} breakOnInfix Should the parsing stop when we hit infix + * nodes?

a number + * instead of an element of a properties object. + * - argTypes: (optional) An array corresponding to each argument of the + * function, giving the type of argument that should be parsed.

Valid + * types: + * - "size": A size-like thing, such as "1em" or "5ex" + * - "color": An html color, like "#abc" or "blue" + * - "original": The same type as the environment that the + * function being parsed is in (e.g. used for the + * bodies of functions like \color where the first + * argument is special and the second argument is + * parsed normally) + * Other possible types (probably shouldn't be used) + * - "text": Text-like (e.g. \text) + * - "math": Normal math + * If undefined, this will be treated as an appropriate length + * array of "original" strings + * - greediness: (optional) The greediness of the function to use ungrouped + * arguments. + * + * E.g. if you have an expression + * \sqrt \frac 1 2 + * since \frac has greediness=2 vs \sqrt's greediness=1, \frac + * will use the two arguments '1' and '2' as its two arguments, + * then that whole function will be used as the argument to + * \sqrt.

If the optional arguments aren't found, + * `null` will be passed to the handler in their place. + * (default 0) + * - infix: (optional) Must be true if the function is an infix operator. + * + * The last argument is that implementation, the handler for the function(s). + * It is called to handle these functions and their arguments. + * It receives two arguments: + * - context contains information and references provided by the parser + * - args is an array of arguments obtained from TeX input + * The context contains the following properties: + * - funcName: the text (i.e. name) of the function, including \ + * - parser: the parser object + * - lexer: the lexer object + * - positions: the positions in the overall string of the function + * and the arguments. + * The latter three should only be used to produce error messages. + * + * The function should return an object with the following keys: + * - type: The type of element that this is.
