Fix the vertical alignment so that it correctly takes into account the descender of the lower element.
Fixes issue 1303.
* Update screenshots
* Revert frac-lines to borders
This PR reverts the rendering of frac-lines from SVG paths back to span borders. This solves the thick grey bar reported by @mbourne in issue #1173.
The result is a frac-line similar to KaTeX v0.9.0-alpha1. The frac-lines are span borders and the CSS contains a `min-width: 1px;` rule to keep those borders visible.
There is one difference between this PR and v0.9.0-alpha1. The earlier work contained a second CSS rule:
```
@media screen and (-webkit-min-device-pixel-ratio: 2), screen and (min-resolution: 192dpi) {
.katex.mfra.fracline {
min-height:0.5px;
}
}
That second CSS rule did not help much. Instead, it caused some lines to disappear. In the thread to issue 1173, people tested the rendering from the proposed approach and reported that frac-lines disappeared only at sized that were already too small to read.

1. Fixes vertical alignment by keeping the base element on the baseline.
2. Assigns horizontal spacing to \underset in a manner that aligns with LaTeX `\binrel`
* Fix flow error
* Add comment
* Allow for shift of mathops
* Update screenshots

* Fix lint error
* Better determination of atom type
* Add comment.
* Add `suppressBaseShift` to ParseNodeTypes
* Make ParseNode `value` payload type-safe.
* Make defineFunction handlers aware of ParseNode data types.
* Add `type` to all function definitions to help determine handler return type.
* Added unit test for case caught only in screenshot test and fixed issue.
* Rename some symbol `Group`s to avoid conflicts with `ParseNode` groups.
Symbol `Group`s are also used as `ParseNode` types. However, `ParseNode`s of
these types always contain a raw text token as opposed to any structured
content. These `ParseNode`s are passed as arguments into function handlers to
create more semantical `ParseNode`s with more structure.
Before this change, "accent" and "op" were both symbol `Group`s and `ParseNode`
types. With this change, these two types (the raw accent token `ParseNode`, and
the structured semantical `ParseNode` are separated for better type-safety on
the `ParseNode` payload).
* stretchy: Remove FlowFixMe for a forced typecast that's no longer needed.
* Stop throwing ParseError when throwOnError is false
`render`, `renderToString`, etc. now catch ParseError and render it to the
raw LaTeX (with proper escaping) and a hover title with the error.
Along the way:
* Use new `katex.__renderToDomTree` in katex-spec's `_getBuilt`.
(This was necessary to get the new error handling in `_getBuilt`.)
* Fix jest results which must always be functions, not strings.
* fix lint
* Fix flow error
Leave error type unspecified, as we check it with instanceof.
* Update katex-spec.js
* \textasciitilde and fix ~ in \verb
* Add support for `\textasciitilde` which reproduces tilde character
in text mode.
* Make `~` render as tilde instead of space within `\verb`,
by manually mapping that character to `\textasciitilde`.
This seems to be the only character that needs such manual mapping
to reproduce LaTeX's `\verb` behavior.
* Add `, -, ', ~ to Verb screenshot test
* Support some Unicode Mathematical Alphanumeric Symbols
This PR adds support for some of the characters in Unicode range U+1D400 to U+1D7FF, [Mathematical Alphanumeric Symbols](https://www.unicode.org/charts/PDF/U1D400.pdf). Specifically, it adds support for:
* A-Z a-z bold
* A-Z a-z bold italic
* A-Z a-z Fractur
* A-Z a-z sans-serif
* A-Z double struck
• A-Z script
Addresses issue #1215 and parts of #260.
* Fix lint error
* Fix MathML, and pick up review comments
* Fix lint error
* Add text mode. Remove sans-serif.
* Fix lint error
* Fixed \mathrm, added screenshotter test
* Change screenshotter test to an array
* Add screenshots
* Picked up review comments. Add characters
* Fix \underset
This PR modifies `\underset` and `\overset` to align with LaTeX behavior when a superscript is applied after the `\underset`. Fixes issue #1275.
I also changed the spacing from KaTeX `mop` to KaTeX `rmel`. The result seems to be a closer visual match to LaTeX.
* Update screenshots
* Fix anchor.toMarkup
* Add space between `a`(tag name) and `href`(attribute name)
* Remove `this.href` appended to `markup` in the template literal
* Add regression test on #1245
* Fix#1212 by supporting `\(...\)` in addition to `$...$` inline math nested inside `\text`. This turned out to be harder than one would think because of the way `$` was being handled specially, while `\(` needed to be handled as a function, which immediately consumed the `\(` token, which meant that the first following token got consumed in text mode instead of math mode (unlike `$` where we could switch the mode before consumption).
* Added new `consumeMode` setting for functions which tells the parser to switch modes just for the consumption of the command token.
* Now that we're working with functions, move all the `$` handling code into `functions/math.js`. Somewhat bizarrely, we can define `$` as a function (nearly identical to `\(`) and it all works (just like we can have single-character macros). This move removed a lot of messy stuff from `Parser.js`: `ParsedDollar`, `ParsedFuncOrArgOrDollar`, `newDollar`, `assertFuncOrArg`, and at least three explicit checks for `if (... === "$")`.
* Moved the `consume()` for the command token from `parseSymbol` to `parseGivenFunction`. This ended up not being strictly necessary, but seems conceptually cleaner.
* Partially address #1027 by setting `consumeMode: "text"` for `\text` commands. As a result, `\text` now instantly switches the mode to `"text"`, so even an unbraced macro argument will properly detect text mode. I added a test for this, which is a slightly weaker form of #1027.
* Support Unicode delimiters
This PR adds support for the Unicode versions of \lfloor, \rfloor, \lceil, \rceil, \lgroup, \rgroup, \lmoustache, \rmoustache, \ulcorner, \urcorner, \llcorner, and \lrcorner.
All the mappings agree with `unicode math`
* Change tests from Parse to Build
Fix#1204 by adding `\yen` support to text mode.
More generally, I checked all the text+mode symbols supported by
[amsfonts](http://mirrors.ctan.org/fonts/amsfonts/doc/amsfonts.pdf)
(see Section 6), and found that `\yen` is the only one lacking text-mode
support.
* Fix \nobreakspace, refactor "regular space" checking
Fix#1199 by adding \nobreakspace to the list of commands/symbols that
behave like a regular space character. Refactor to put that list in one
place, and use an object so it checks instantly instead of sequentially.
* Copy test from #1201
* Work around negative space bug in Chrome
Fix#984
The screenshot test is still somewhat defective, showing a space before
the "post" text (a period). This seems limited to the screenshotter, however,
as it works fine in the tester via
http://localhost:7936/?text=%5Cfbox%7B%5C%241%2C%5C!000%2C%5C!000%7D%5CKaTeX&display=0&after=.
* Update screenshots
* Switch to inherited `width: min-content`
* unicodeTextInMathMode setting
* When `unicodeTextInMathMode` is `true`, accented letters from
`unicodeSymbols.js`, and CJK and other supported languages,
get added support in math mode (as requested in #895).
* When `unicodeTextInMathMode` is `false, all of these stop working in
math mode, and are only supported in text mode (matching XeTeX behavior).
Note that this is a backwards incompatibility with some 0.9.0 alpha/betas.
* Fix handling of Unicode characters ð, Å, å
* Fix double handling of ð (math maps to \eth, not special Unicode character)
* Remove Åå special math handling, thanks to #1125
* Forbid extraLatin when unicodeTextInMathMode is false
* Padding over \sqrt and Paths for frac-line
This replaces two earlier PRs.
* Restore reaction arrows
* regenerate screenshots
* Set line padding in a constant
* Update with latest master
* Fix lint error
* update screenshots
* Support Reaction Arrows
This PR is written to supply reaction arrows for a future `mhchem` extension. `mhchem` uses seven reaction arrows. Four of them correspond to extensible arrows already available in KaTeX. This PR creates the other three.
These arrows will also be useful to chemists writing about reactions when `mhchem` is unavailable.
Three new extensible arrows are introduced: `\xrightleftarrows`, `\xrightequilibrium`, and `\xleftequilibrium`.
These names are not `mhchem`’s user-facing function names. In `mhchem`, users would call these arrows with syntax such as: `\ce{A<-->B}`, or `\ce{A<=>>B}`, or `\ce{A<<=>B}`. I’ve provided names that look more like the other extensible arrow names. That’s probably worth some discussion.
* generate screenshots for ReactionArrows
* Increase overlap in arrow shaft
To prevent a small gap when rendering in very large font sizes.
* Adjust upper text vert alignment. Add warning.
* Limit alignment adjustment to \xleftequilibrium
* generate screenshots for reaction arrows
* Enable spacing functions in text mode
Spacing functions such as `\;` or `\quad` should be accepted in either math mode or text mode
* Add tests
* Fix tests
* Fix lint error
* update fonts and metrics so that accents are positioned correctly
* fix degree symbol, move more accents into the 0x2c0-0x2df range

We want to inherit CSS properties that apply to both text and SVG
but we don't want to inherit styles that affect SVG without affecting text.
This patch adds a screenshot test to verify this.
* Use JS for spacing between atoms instead of CSS
Summary:
This is the first step towards creating an intermediate representation
that can be used to generate HTML, SVG, and Canvas commands for rendering.
By generating spans that contain the width of the spaces instead of
relying on CSS sibling rules we'll be able to one day replaces the spans
with intermeidate 'Glue' nodes (in a later PR).
An added benefit of this approach is that is enables us to programmatically
change the values for thinspace, mediumspace, and thickspace which will
allow us to implement the \setlength command.
Test Plan:
- npm test
- dockers/Screenshotter/screenshotter.sh --verify
* fixed failures in BinCancellation, BoldSymbol, and OperatorName
* update screenshots
* don't use current size when determining size of spaces, update more screenshots
* fix spacing in SizingBaseline and StyleSwitching
* actually do the right thing for sizing groups
* fix \not for Chrome and Firefox
* do TODOs
* address feedback from the code review
* fix issue in delimsizing.js
* add TODO to think about a better solution in href.js
* fix typos, simplify href, be honest about paddingLeft for \not
* Support more scripts in \text{} environments.
This diff is a follow-up to PR #1060 which added support for Indic scripts.
In order to support Czech, Turkish and Hungarian text (at least) inside
\text{} environments, we need to recognize the Latin Extended A and B
Unicode blocks. The patch also adds support for Georgian, and enhances
support for Cyrillic by defining the entire Cyrillic unicode block instead
of defining symbols for a subset of Cyrillic letters as we did previously.
* Only return fontMetrics for supported Unicode scripts in text mode
The Unicode scripts listed in unicodeScripts.js are supported in text mode
but getCharacterMetrics() was returning fake metrics for them even in
math mode. This caused bad handling of \boldsymbol\imath
* use Mode from types.js
* Create a separate entry point for webpack
Created a webpack entry point for KaTeX, which imports katex.less. As
flow[1] and jest[2] doesn't support CSS modules natively, a separate
entry point is used and it is not flowtyped.

Changed version range to include IE-compatible version
* Add support for \aa, \AA, \lq, \rq, \lbrack, \rbrack
The lack of \aa and \AA was reported in #1066. Added these
via simple macros, with supporting tests. Also add \lq, \rq,
\lbrack, \rbrack as aliases for "`", "'", "[", "]" which were
in the same area of latex.ltx.
* removed duplicate comment
This patch just makes KaTeX recognize Unicode codepoints in the
range \u0900-\u109f so that those South and Southeast Asian scripts
do not get automatically rejected.
The patch also generalizes the way that Unicode blocks are handled
to make it easier to add support for new scripts in the future.
src/unicodeRegexes.js is replaced with the new file src/unicodeScripts.js
* Unicode accents
* Lexer now looks for combining dicritical marks and adds them to the same character
* Parser's `parseSymbol` now recognizes both combined and uncombined forms of Unicode accents, and builds accent objects just like the accent functions
* Added CJK support to math mode (not just text mode)
* Add invalid combining character test
* Add MathML test
* Add weak support for other Latin-1 characters
This maintains backwards compatibility, but it uses the wrong font.
There's a TODO to fix this later.
