That left-over shaft is not shown.\n// Instead, it is sliced off because the span's CSS has overflow: hidden.\n// Thus, the reader sees an arrow that matches the subject matter width\n// without distortion.\n// Some functions, such as \\cancel, need to vary their aspect ratio. These\n// functions do not get the overflow SVG treatment.\n// Second Brush Stroke\n// Low resolution monitors struggle to display images in fine detail.\n// So browsers apply anti-aliasing. A long straight arrow shaft therefore\n// will sometimes appear as if it has a blurred edge.\n// To mitigate this, these SVG files contain a second \"brush-stroke\" on the\n// arrow shafts. That is, a second long thin rectangular SVG path has been\n// written directly on top of each arrow shaft. This reinforcement causes\n// some of the screen pixels to display as black instead of the anti-aliased\n// gray pixel that a single path would generate. So we get arrow shafts\n// whose edges appear to be sharper.\n// In the katexImagesData object just below, the dimensions all\n// correspond to path geometry inside the relevant SVG.\n// For example, \\overrightarrow uses the same arrowhead as glyph U+2192\n// from the KaTeX Main font. The scaling factor is 1000.\n// That is, inside the font, that arrowhead is 522 units tall, which\n// corresponds to 0.522 em inside the document.\n\n\nvar katexImagesData = {\n // path(s), minWidth, height, align\n overrightarrow: [[\"rightarrow\"], 0.888, 522, \"xMaxYMin\"],\n overleftarrow: [[\"leftarrow\"], 0.888, 522, \"xMinYMin\"],\n underrightarrow: [[\"rightarrow\"], 0.888, 522, \"xMaxYMin\"],\n underleftarrow: [[\"leftarrow\"], 0.888, 522, \"xMinYMin\"],\n xrightarrow: [[\"rightarrow\"], 1.469, 522, \"xMaxYMin\"],\n \"\\\\cdrightarrow\": [[\"rightarrow\"], 3.0, 522, \"xMaxYMin\"],\n // CD minwwidth2.5pc\n xleftarrow: [[\"leftarrow\"], 1.469, 522, \"xMinYMin\"],\n \"\\\\cdleftarrow\": [[\"leftarrow\"], 3.0, 522, \"xMinYMin\"],\n Overrightarrow: [[\"doublerightarrow\"], 0.888, 560, \"xMaxYMin\"],\n xRightarrow: [[\"doublerightarrow\"], 1.526, 560, \"xMaxYMin\"],\n xLeftarrow: [[\"doubleleftarrow\"], 1.526, 560, \"xMinYMin\"],\n overleftharpoon: [[\"leftharpoon\"], 0.888, 522, \"xMinYMin\"],\n xleftharpoonup: [[\"leftharpoon\"], 0.888, 522, \"xMinYMin\"],\n xleftharpoondown: [[\"leftharpoondown\"], 0.888, 522, \"xMinYMin\"],\n overrightharpoon: [[\"rightharpoon\"], 0.888, 522, \"xMaxYMin\"],\n xrightharpoonup: [[\"rightharpoon\"], 0.888, 522, \"xMaxYMin\"],\n xrightharpoondown: [[\"rightharpoondown\"], 0.888, 522, \"xMaxYMin\"],\n xlongequal: [[\"longequal\"], 0.888, 334, \"xMinYMin\"],\n \"\\\\cdlongequal\": [[\"longequal\"], 3.0, 334, \"xMinYMin\"],\n xtwoheadleftarrow: [[\"twoheadleftarrow\"], 0.888, 334, \"xMinYMin\"],\n xtwoheadrightarrow: [[\"twoheadrightarrow\"], 0.888, 334, \"xMaxYMin\"],\n overleftrightarrow: [[\"leftarrow\", \"rightarrow\"], 0.888, 522],\n overbrace: [[\"leftbrace\", \"midbrace\", \"rightbrace\"], 1.6, 548],\n underbrace: [[\"leftbraceunder\", \"midbraceunder\", \"rightbraceunder\"], 1.6, 548],\n underleftrightarrow: [[\"leftarrow\", \"rightarrow\"], 0.888, 522],\n xleftrightarrow: [[\"leftarrow\", \"rightarrow\"], 1.75, 522],\n xLeftrightarrow: [[\"doubleleftarrow\", \"doublerightarrow\"], 1.75, 560],\n xrightleftharpoons: [[\"leftharpoondownplus\", \"rightharpoonplus\"], 1.75, 716],\n xleftrightharpoons: [[\"leftharpoonplus\", \"rightharpoondownplus\"], 1.75, 716],\n xhookleftarrow: [[\"leftarrow\", \"righthook\"], 1.08, 522],\n xhookrightarrow: [[\"lefthook\", \"rightarrow\"], 1.08, 522],\n overlinesegment: [[\"leftlinesegment\", \"rightlinesegment\"], 0.888, 522],\n underlinesegment: [[\"leftlinesegment\", \"rightlinesegment\"], 0.888, 522],\n overgroup: [[\"leftgroup\", \"rightgroup\"], 0.888, 342],\n undergroup: [[\"leftgroupunder\", \"rightgroupunder\"], 0.888, 342],\n xmapsto: [[\"leftmapsto\", \"rightarrow\"], 1.5, 522],\n xtofrom: [[\"leftToFrom\", \"rightToFrom\"], 1.75, 528],\n // The next three arrows are from the mhchem package.\n // In mhchem.sty, min-length is 2.0em.

Since TeX isn't context-free, standard parsers don't work particularly\n * well.\n *\n * The strategy of this parser is as such:\n *\n * The main functions (the `.parse...` ones) take a position in the current\n * parse string to parse tokens from. The lexer (found in Lexer.js, stored at\n * this.gullet.lexer) also supports pulling out tokens at arbitrary places. When\n * individual tokens are needed at a position, the lexer is called to pull out a\n * token, which is then used.\n *\n * The parser has a property called \"mode\" indicating the mode that\n * the parser is currently in. Currently it has to be one of \"math\" or\n * \"text\", which denotes whether the current environment is a math-y\n * one or a text-y one (e.g. inside \\text). Currently, this serves to\n * limit the functions which can be used in text mode.\n *\n * The main functions then return an object which contains the useful data that\n * was parsed at its given point, and a new position at the end of the parsed\n * data. The main functions can call each other and continue the parsing by\n * using the returned position as a new starting point.\n *\n * There are also extra `.handle...` functions, which pull out some reused\n * functionality into self-contained functions.\n *\n * The functions return ParseNodes.\n */\nclass Parser {\n constructor(input, settings) {\n this.mode = void 0;\n this.gullet = void 0;\n this.settings = void 0;\n this.leftrightDepth = void 0;\n this.nextToken = void 0;\n // Start in math mode\n this.mode = \"math\"; // Create a new macro expander (gullet) and (indirectly via that) also a\n // new lexer (mouth) for this parser (stomach, in the language of TeX)\n\n this.gullet = new MacroExpander(input, settings, this.mode); // Store the settings for use in parsing\n\n this.settings = settings; // Count leftright depth (for \\middle errors)\n\n this.leftrightDepth = 0;\n }\n /**\n * Checks a result to make sure it has the right type, and throws an\n * appropriate error otherwise.\n */\n\n\n expect(text, consume) {\n if (consume === void 0) {\n consume = true;\n }\n\n if (this.fetch().text !== text) {\n throw new ParseError(\"Expected '\" + text + \"', got '\" + this.fetch().text + \"'\", this.fetch());\n }\n\n if (consume) {\n this.consume();\n }\n }\n /**\n * Discards the current lookahead token, considering it consumed.\n */\n\n\n consume() {\n this.nextToken = null;\n }\n /**\n * Return the current lookahead token, or if there isn't one (at the\n * beginning, or if the previous lookahead token was consume()d),\n * fetch the next token as the new lookahead token and return it.\n */\n\n\n fetch() {\n if (this.nextToken == null) {\n this.nextToken = this.gullet.expandNextToken();\n }\n\n return this.nextToken;\n }\n /**\n * Switches between \"text\" and \"math\" modes.\n */\n\n\n switchMode(newMode) {\n this.mode = newMode;\n this.gullet.switchMode(newMode);\n }\n /**\n * Main parsing function, which parses an entire input.\n */\n\n\n parse() {\n if (!this.settings.globalGroup) {\n // Create a group namespace for the math expression.\n // (LaTeX creates a new group for every $...$, $$...$$, \\[...\\].)\n this.gullet.beginGroup();\n } // Use old \\color behavior (same as LaTeX's \\textcolor) if requested.\n // We do this within the group for the math expression, so it doesn't\n // pollute settings.macros.\n\n\n if (this.settings.colorIsTextColor) {\n this.gullet.macros.set(\"\\\\color\", \"\\\\textcolor\");\n }\n\n try {\n // Try to parse the input\n var parse = this.parseExpression(false); // If we succeeded, make sure there's an EOF at the end\n\n this.expect(\"EOF\"); // End the group namespace for the expression\n\n if (!this.settings.globalGroup) {\n this.gullet.endGroup();\n }\n\n return parse; // Close any leftover groups in case of a parse error.\n } finally {\n this.gullet.endGroups();\n }\n }\n /**\n * Fully parse a separate sequence of tokens as a separate job.\n * Tokens should be specified in reverse order, as in a MacroDefinition.\n */\n\n\n subparse(tokens) {\n // Save the next token from the current job.\n var oldToken = this.nextToken;\n this.consume(); // Run the new job, terminating it with an excess '}'\n\n this.gullet.pushToken(new Token(\"}\"));\n this.gullet.pushTokens(tokens);\n var parse = this.parseExpression(false);\n this.expect(\"}\"); // Restore the next token from the current job.\n\n this.nextToken = oldToken;\n return parse;\n }\n\n /**\n * Parses an \"expression\", which is a list of atoms.\n *\n * `breakOnInfix`: Should the parsing stop when we hit infix nodes?
