* Fix frac lline
For frac-line, use an SVG line in an extra tall span.
I still need to think of a way to adust `vertical-separator`.
* Fix spaces in katex.less
* regenerate screenshots
* update HorizontalBraces and StrikeThrough screenshots
* Make accents zero width
Make the width of an accented character equal to the width of the character,
by making accents zero width. In particular, fixes#1028 (`\ddot\imath`).
This involved reworking all of the accent offset machinery, in particular
skew and accent-hungarian. A bit cleaner now.
Also added support for the new width character metrics in symbolNode.
* Update AccentsText test
* Fix comment
* Implement \TextOrMath, \@secondoftwo
* Parser now tells MacroExpander about mode switching. (This seems preferable
to a circular reference between Parser and MacroExpander.)
* Implement \TextOrMath
* Improve when we switch modes so that this actually works,
in all cases except single-symbol arguments.
* Add \@secondoftwo to match \@firstoftwo.
* Add comments documenting all the conditional macros
* Define type for switchMode
* Fix mode detection for ligatures
* Switch mode before the call to parseSymbol() in parseGroup
This fixes the Colorbox screenshot test.
* Adding support for SansSerif-Bold
* Updating to include SansSerif Italic.
* WIP
* Working text stacking
* More robust screenshot.
* Don't want to break users :)
* Updating per PR comments.
* Fixing Unicode and updating snapshots.
* Adding suggested tests.
* Opting to use old method for unit testing.
* Adding TODO
* added support for \boldsymbol
* added \boldsymbol tests
* added \boldsymbol screenshots
* added \bm, snapshot, updated screenshots
* updated snapshot for \boldsymbol
* properly display \imath and 2 in boldsymbol
* implemented \boldsymbol for +
* fix typo, remove boldsymbolLetters hardcode
* make comment about using Main-Bold more general
* fixed trailing space CI error
* Support Unicode middle dot
This PR adds support for Unicode characters U+00B7 MIDDLE DOT and U+22C5 DOT OPERATOR.
* Use escapes for tests. Edit macro comment.
* Refactor \kern, proper \mkern support, add \hskip
* Move \kern, \mkern into functions directory
* Add \hskip, \mskip support (but without supporting plus/minus)
* Properly separate \kern, \hskip from \mkern, \mskip.
(The former work in both modes, and don't support mu units.
The latter work only in math mode and only support mu units.)
* Render \kern etc. using MathML <mspace>
* Implement \TeX macro
* Implement \LaTeX
* New KaTeX logo \katex
* Rename hskip.js -> kern.js
* Tweak katex \kern to 0.16em
* \katex kern -.17em
* Compute A raise height in \LaTeX and \katex
* Switch mu unit errors to warnings
* LaTeX screenshot test
* Replace \KaTeX with macro definition
* Update screenshots with \KaTeX in them
* Fix font selection for \*TeX macros
* \hspace*, \@ifstar, \@ifnextchar, \@firstoftwo
* Support both \hspace and \hspace* (still aliasing to \kern)
using new \@ifstar
* \@ifstar is a macro using new \@ifnextchar and \@firstoftwo
(same definition as LaTeX)
* \@firstoftwo and \@ifnextchar use available MacroParser features
to act as they do in LaTeX.
* Also new method pushTokens (which I almost used but didn't end up),
and moved pushToken next to it and popToken.
* Fix flow errors; generalize MacroDefinition
* Add tests for macros
* Support Unicode Symbols
This is the third in a series of PRs to give KaTeX the ability to recognize Unicode character input. This one supports some but not all letter-like symbols and some other symbols. All the characters in this PR will produce `textord` atoms in `math` mode.
The list is not comprehensive. It’s a bit eclectic. Some of these characters are important. Others were just easy to include. A few important characters are omitted because it wasn’t clear to me which is the best way to implement them. I’ll address those characters in future PRs.
* Add comments. Remove RegEx.
* Fix omitted parens
* Change frac-line from border to full span
Change `frac-line` and `vertical-separator`. Instead of using span borders, fill entire span using a `box-shadow`.
This change will enable more dependable engagement of the `min-height` CSS.
* Fix indentation
* Fix indent again
* Change box shadow to inline SVG
* Fix lint error
* regenerate screenshots after switching to SVG for fraction bars
* Change \undeertilde to \utilde
In PR #670, I made an error. The function that should have been `\utilde` I named instead `\undertilde`.
There is an `\undertilde` from the `wsuipa` package, but it is a text-mode non-stretchy function. The proper command name is `\utilde`, a math-mode, stretchy function from packge `undertilde`.
This PR fixes my error.
* Fix screenshotter test
* Support Unicode Big Operators
This is the sixth in a series of PRs to give KaTeX the ability to recognize Unicode character input.
This is the final PR in this series that will submit characters in bulk. After this, there come some characters whose alias or atom type was not obvious. I'll turn in PRs for them, too, but only after they are vetted.
* Move constants outside of main functions
* Replace ∫ with \u222b
* Add backslash
* Support Unicode Arrows
This is the second in a series of PRs to give KaTeX the ability to recognize Unicode character input.
All the characters in this PR will produce `rel` atoms.
* Support Unicode Negated Relations
This is the fifth in a series of PRs to give KaTeX the ability to recognize Unicode character input.
All the characters in this PR will produce `rel` atoms.
* Add parse tests
* Fix AMS functions
Fix a brain cramp.
* Add internal aliases to code comments
This PR implements `\mathchoice` function.
I once created PR on the wrong branch. Sorry for the mess.
This is particularly useful when one defines custom macro for "big operators".
For example:
```latex
\newcommand{\infdisj}{%
\mathop{%
\mathchoice{% display
\bigvee\hspace{-2ex}\bigvee%
}{ % inline
\bigvee\hspace{-1.75ex}\bigvee%
}{ % script
\bigvee\hspace{-1.4ex}\bigvee%
}{ % scriptscript
\bigvee\hspace{-1ex}\bigvee%
}}}
```
This is the fourth in a series of PRs to give KaTeX the ability to recognize Unicode character input.
All the characters in this PR will produce `bin` atoms.
* Implements the alignat environment for flexible math spacing
* Renames alignat[*] to alignedat and factors out duplicate code of aligned and alignedat as alignedHandler
* Adds aligned at to screenshotter
* alignedat screenshots
* Implements the alignat environment for flexible math spacing
* Renames alignat[*] to alignedat and factors out duplicate code of aligned and alignedat as alignedHandler
* Adds aligned at to screenshotter
* alignedat screenshots
* fix style nit
* fix lint
* Fix#946
Issue #946 identified a case in which `array.js` ate the final row of a well-written `aligned` environment.
This PR modifies code from PR #479 to fix this problem and to also continue to eat a trailing `\\` submitted to any environment.
* Fix bug and add tests
* Add final newline to test.
Doh!
* Support Unicode relations
This is the first in a series of PRs to give KaTeX the ability to recognize Unicode character input. The code in this PR follows the style of PR #410.
All the characters in this PR will produce rel atoms. I’ll submit PRs for other atom types later.
* Fix lint error.
* Correct mapping errors
This commit fixes a brain cramp of mine.
Fixes several issues with space handling: (fix#910)
1. "Control symbols" (as they're called in the TeXbook), such as `\\`, should
not have spaces eaten after them (only "control words" such as `\foo`).
2. In math mode, spaces should be consumed at the parser level, not the
gullet level. This enables `\\ [x]` to parse differently from `\\[x]`
3. Eat spaces between arguments, so `\frac x y` still works.
(This used to work only because math mode ate all spaces.
The analog in text mode wouldn't have worked.)
Also eat spaces in initial arguments in math mode, and before ^ and _ in atoms.

* Fix spaces and style handling
* Implement @kevinbarabash's comments
* Make error clearly an assertion failure
* verb screenshot for Chrome
* Fix \sqrt zoom in Safari
This PR evades a Safari bug which causes nested SVGs to zoom improperly. `\sqrt` and single-ended arrow SVGs have been modified.
These have been converted from nested SVGs to single level. Their long tails are now sliced off using CSS `overflow: hidden`.
Safari will still improperly zoom any double-ended stretchy arrows and horizontal braces.
* Fix \sqrt{}
Even if the function argument is empty, still render an SVG whose width equals the surd glyph.
* Fix tall \sqrt when scaled
* update screenshots affected by sqrt fixes
* more screenshots after changes to fix sqrt
* Pick up review comments
* Support \colorbox and \\fcolorbox
These are functions from the `color` package. They accept text, not math. They also have padding similar to `\fbox`.
Because of the padding, the code in `buildHTML` is intermixed with the `\fbox` code. I have not (yet) created a new file in the functions folder. This way, the reviewer gets a cleaner diff.
* Fix lint error
* colorbox screenshots
* Pick up review comments
* To @flow: fontMetrics, fontMetricsData, Options, Settings, Style
* Don't overuse $Shape, improve type checking for fontMetrics*, make maxSize required in OptionsData and update callers.
* Remove eslintrc globals change, since eslint-plugin-flowtype makes it redundant.
* Remove extra ?s in Options and Settings
* Undo removal of width in fontMetrics and switch to `T | void` for nullable types in Options
* fix typing of FontMetrics
* Improve SVG Performance
This PR introduces three new classes: `svgNode`, `pathNode`, and `lineNode`. SVG data is then loaded into the domTree exclusively via instances of these classes.
`innerHTML` is banished.
* Fix lint errors
* Fix \cancel typo
* Fix sqrt height
* Adjust min-lenght
Adjust some of the extensible arrows to get a min-length that matches glyph length of the long arrows in KaTeX Main font range from Unicode 27F5 to 27FC.
The accent arrows still get min-lengths that match the arrows in the Unicode 2100 range.
* regenerate screenshots after optimizing SVG code
* update DisplayStyle screenshot for Chrome
* update OverUnderset and Smash screenshots for Chrome as well
* Remove escapes from template strings
* Pick up review comments
