* constant like PR_PLAIN. index_n-1 <= index_n, and style_n-1 applies to
* all characters in sourceCode[index_n-1:index_n].
*
* The stylePatterns is a list whose elements have the form
* [style : string, pattern : RegExp, DEPRECATED, shortcut : string].
*
* Style is a style constant like PR_PLAIN, or can be a string of the
* form 'lang-FOO', where FOO is a language extension describing the
* language of the portion of the token in $1 after pattern executes.
* E.g., if style is 'lang-lisp', and group 1 contains the text
* '(hello (world))', then that portion of the token will be passed to the
* registered lisp handler for formatting.
* The text before and after group 1 will be restyled using this decorator
* so decorators should take care that this doesn't result in infinite
* recursion. For example, the HTML lexer rule for SCRIPT elements looks
* something like ['lang-js', /<[s]cript>(.+?)<\/script>/]. This may match
* '<script>foo()<\/script>', which would cause the current decorator to
* be called with '<script>' which would not match the same rule since
* group 1 must not be empty, so it would be instead styled as PR_TAG by
* the generic tag rule. The handler registered for the 'js' extension would
* then be called with 'foo()', and finally, the current decorator would
* be called with '<\/script>' which would not match the original rule and
* so the generic tag rule would identify it as a tag.
*
* Pattern must only match prefixes, and if it matches a prefix, then that
* match is considered a token with the same style.
*
* Context is applied to the last non-whitespace, non-comment token
* recognized.
*
* Shortcut is an optional string of characters, any of which, if the first
* character, gurantee that this pattern and only this pattern matches.
*
* @param {Array} shortcutStylePatterns patterns that always start with
* a known character. Must have a shortcut string.

CSS Beautifier
---------------
Written by Harutyun Amirjanyan, (amirjanyan@gmail.com)
Based on code initially developed by: Einar Lielmanis, <einar@beautifier.io>
https://beautifier.io/
Usage:
css_beautify(source_text);
css_beautify(source_text, options);
The options are (default in brackets):
indent_size (4) — indentation size,
indent_char (space) — character to indent with,
selector_separator_newline (true) - separate selectors with newline or
not (e.g. "a,\nbr" or "a, br")
end_with_newline (false) - end with a newline
newline_between_rules (true) - add a new line after every css rule
space_around_selector_separator (false) - ensure space around selector separators:
'>', '+', '~' (e.g. "a>b" -> "a > b")
e.g
css_beautify(css_source_text, {
'indent_size': 1,
'indent_char': '\t',
'selector_separator': ' ',
'end_with_newline': false,
'newline_between_rules': true,
'space_around_selector_separator': true
});

Style HTML
---------------
Written by Nochum Sossonko, (nsossonko@hotmail.com)
Based on code initially developed by: Einar Lielmanis, <einar@beautifier.io>
https://beautifier.io/
Usage:
style_html(html_source);
style_html(html_source, options);
The options are:
indent_inner_html (default false) — indent <head> and <body> sections,
indent_size (default 4) — indentation size,
indent_char (default space) — character to indent with,
wrap_line_length (default 250) - maximum amount of characters per line (0 = disable)
brace_style (default "collapse") - "collapse" | "expand" | "end-expand" | "none"
put braces on the same line as control statements (default), or put braces on own line (Allman / ANSI style), or just put end braces on own line, or attempt to keep them where they are.
inline (defaults to inline tags) - list of tags to be considered inline tags
unformatted (defaults to inline tags) - list of tags, that shouldn't be reformatted
content_unformatted (defaults to ["pre", "textarea"] tags) - list of tags, whose content shouldn't be reformatted
indent_scripts (default normal) - "keep"|"separate"|"normal"
preserve_newlines (default true) - whether existing line breaks before elements should be preserved
Only works before elements, not inside tags or for text.
max_preserve_newlines (default unlimited) - maximum number of line breaks to be preserved in one chunk
indent_handlebars (default false) - format and indent {{#foo}} and {{/foo}}
end_with_newline (false) - end with a newline
extra_liners (default [head,body,/html]) -List of tags that should have an extra newline before them.
e.g.
style_html(html_source, {
'indent_inner_html': false,
'indent_size': 2,
'indent_char': ' ',
'wrap_line_length': 78,
'brace_style': 'expand',
'preserve_newlines': true,
'max_preserve_newlines': 5,
'indent_handlebars': false,
'extra_liners': ['/html']
});

JS Beautifier
---------------
Written by Einar Lielmanis, <einar@beautifier.io>
https://beautifier.io/
Originally converted to javascript by Vital, <vital76@gmail.com>
"End braces on own line" added by Chris J. Shull, <chrisjshull@gmail.com>
Parsing improvements for brace-less statements by Liam Newman <bitwiseman@beautifier.io>
Usage:
js_beautify(js_source_text);
js_beautify(js_source_text, options);
The options are:
indent_size (default 4) - indentation size,
indent_char (default space) - character to indent with,
preserve_newlines (default true) - whether existing line breaks should be preserved,
max_preserve_newlines (default unlimited) - maximum number of line breaks to be preserved in one chunk,
jslint_happy (default false) - if true, then jslint-stricter mode is enforced.
jslint_happy !jslint_happy
---------------------------------
function () function()
switch () { switch() {
case 1: case 1:
break; break;
} }
space_after_anon_function (default false) - should the space before an anonymous function's parens be added, "function()" vs "function ()",
NOTE: This option is overridden by jslint_happy (i.e. if jslint_happy is true, space_after_anon_function is true by design)
brace_style (default "collapse") - "collapse" | "expand" | "end-expand" | "none" | any of the former + ",preserve-inline"
put braces on the same line as control statements (default), or put braces on own line (Allman / ANSI style), or just put end braces on own line, or attempt to keep them where they are.
preserve-inline will try to preserve inline blocks of curly braces
space_before_conditional (default true) - should the space before conditional statement be added, "if(true)" vs "if (true)",
unescape_strings (default false) - should printable characters in strings encoded in \xNN notation be unescaped, "example" vs "\x65\x78\x61\x6d\x70\x6c\x65"
wrap_line_length (default unlimited) - lines should wrap at next opportunity after this number of characters.
NOTE: This is not a hard limit. Lines will continue until a point where a newline would
be preserved if it were present.
end_with_newline (default false) - end output with a newline
e.g
js_beautify(js_source_text, {
'indent_size': 1,
'indent_char': '\t'
});

/**
* This file contains metrics regarding fonts and individual symbols. The sigma
* and xi variables, as well as the metricMap map contain data extracted from
* TeX, TeX font metrics, and the TTF files. These data are then exposed via the
* `metrics` variable and the getCharacterMetrics function.
*/
// In TeX, there are actually three sets of dimensions, one for each of
// textstyle (size index 5 and higher: >=9pt), scriptstyle (size index 3 and 4:
// 7-8pt), and scriptscriptstyle (size index 1 and 2: 5-6pt). These are
// provided in the the arrays below, in that order.
//
// The font metrics are stored in fonts cmsy10, cmsy7, and cmsy5 respsectively.
// This was determined by running the following script:
//
// latex -interaction=nonstopmode \
// '\documentclass{article}\usepackage{amsmath}\begin{document}' \
// '$a$ \expandafter\show\the\textfont2' \
// '\expandafter\show\the\scriptfont2' \
// '\expandafter\show\the\scriptscriptfont2' \
// '\stop'
//
// The metrics themselves were retreived using the following commands:
//
// tftopl cmsy10
// tftopl cmsy7
// tftopl cmsy5
//
// The output of each of these commands is quite lengthy. The only part we
// care about is the FONTDIMEN section. Each value is measured in EMs.

// Very Long SVGs
// Many of the KaTeX stretchy wide elements use a long SVG image and an
// overflow: hidden tactic to achieve a stretchy image while avoiding
// distortion of arrowheads or brace corners.
// The SVG typically contains a very long (400 em) arrow.
// The SVG is in a container span that has overflow: hidden, so the span
// acts like a window that exposes only part of the SVG.
// The SVG always has a longer, thinner aspect ratio than the container span.
// After the SVG fills 100% of the height of the container span,
// there is a long arrow shaft left over. That left-over shaft is not shown.
// Instead, it is sliced off because the span's CSS has overflow: hidden.
// Thus, the reader sees an arrow that matches the subject matter width
// without distortion.
// Some functions, such as \cancel, need to vary their aspect ratio. These
// functions do not get the overflow SVG treatment.
// Second Brush Stroke
// Low resolution monitors struggle to display images in fine detail.
// So browsers apply anti-aliasing. A long straight arrow shaft therefore
// will sometimes appear as if it has a blurred edge.
// To mitigate this, these SVG files contain a second "brush-stroke" on the
// arrow shafts. That is, a second long thin rectangular SVG path has been
// written directly on top of each arrow shaft. This reinforcement causes
// some of the screen pixels to display as black instead of the anti-aliased
// gray pixel that a single path would generate. So we get arrow shafts
// whose edges appear to be sharper.
// In the katexImagesData object just below, the dimensions all
// correspond to path geometry inside the relevant SVG.
// For example, \overrightarrow uses the same arrowhead as glyph U+2192
// from the KaTeX Main font. The scaling factor is 1000.
// That is, inside the font, that arrowhead is 522 units tall, which
// corresponds to 0.522 em inside the document.

*
* The functions take a parameter `center`, which determines if the delimiter
* should be centered around the axis.
*
* Then, there are three exposed functions. `sizedDelim` makes a delimiter in
* one of the given sizes. This is used for things like `\bigl`.
* `customSizedDelim` makes a delimiter with a given total height+depth. It is

/**
* This file contains the parser used to parse out a TeX expression from the
* input. Since TeX isn't context-free, standard parsers don't work particularly
* well.
*
* The strategy of this parser is as such:
*
* The main functions (the `.parse...` ones) take a position in the current
* parse string to parse tokens from. The lexer (found in Lexer.js, stored at
* this.gullet.lexer) also supports pulling out tokens at arbitrary places. When
* individual tokens are needed at a position, the lexer is called to pull out a
* token, which is then used.
*
* The parser has a property called "mode" indicating the mode that
* the parser is currently in. Currently it has to be one of "math" or
* "text", which denotes whether the current environment is a math-y
* one or a text-y one (e.g. inside \text). 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 functions return ParseNodes.

/**
* Creates a `lodash` object which wraps `value` to enable implicit method
* chain sequences. Methods that operate on and return arrays, collections,
* and functions can be chained together. Methods that retrieve a single value
* or may return a primitive value will automatically end the chain sequence
* and return the unwrapped value. Otherwise, the value must be unwrapped
* with `_#value`.
*
* Explicit chain sequences, which must be unwrapped with `_#value`, may be
* enabled using `_.chain`.
*
* The execution of chained methods is lazy, that is, it's deferred until
* `_#value` is implicitly or explicitly called.
*
* Lazy evaluation allows several methods to support shortcut fusion.
* Shortcut fusion is an optimization to merge iteratee calls; this avoids
* the creation of intermediate arrays and can greatly reduce the number of
* iteratee executions. Sections of a chain sequence qualify for shortcut
* fusion if the section is applied to an array and iteratees accept only
* one argument. The heuristic for whether a section qualifies for shortcut
* fusion is subject to change.
*
* Chaining is supported in custom builds as long as the `_#value` method is
* directly or indirectly included in the build.
*
* In addition to lodash methods, wrappers have `Array` and `String` methods.
*
* The wrapper `Array` methods are:
* `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
*
* The wrapper `String` methods are:
* `replace` and `split`
*
* The wrapper methods that support shortcut fusion are:
* `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,
* `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
* `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
*
* The chainable wrapper methods are:
* `after`, `ary`, `assign`, `assignIn`, `assignInWith`, `assignWith`, `at`,
* `before`, `bind`, `bindAll`, `bindKey`, `castArray`, `chain`, `chunk`,
* `commit`, `compact`, `concat`, `conforms`, `constant`, `countBy`, `create`,
* `curry`, `debounce`, `defaults`, `defaultsDeep`, `defer`, `delay`,
* `difference`, `differenceBy`, `differenceWith`, `drop`, `dropRight`,

/**
* @ignore
* Sub-class specialization of EventHandler base class.
*
* TaskLoop allows to schedule a task function being called (optionnaly repeatedly) on the main loop,
* scheduled asynchroneously, avoiding recursive calls in the same tick.
*
* The task itself is implemented in `doTick`. It can be requested and called for single execution
* using the `tick` method.
*
* It will be assured that the task execution method (`tick`) only gets called once per main loop "tick",
* no matter how often it gets requested for execution. Execution in further ticks will be scheduled accordingly.
*
* If further execution requests have already been scheduled on the next tick, it can be checked with `hasNextTick`,
* and cancelled with `clearNextTick`.
*
* The task can be scheduled as an interval repeatedly with a period as parameter (see `setInterval`, `clearInterval`).
*
* Sub-classes need to implement the `doTick` method which will effectively have the task execution routine.
*
* Further explanations:
*
* The baseclass has a `tick` method that will schedule the doTick call. It may be called synchroneously
* only for a stack-depth of one. On re-entrant calls, sub-sequent calls are scheduled for next main loop ticks.
*
* When the task execution (`tick` method) is called in re-entrant way this is detected and
* we are limiting the task execution per call stack to exactly one, but scheduling/post-poning further
* task processing on the next main loop iteration (also known as "next tick" in the Node/JS runtime lingo).
