* 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
This is a workaround for #836 for the command case of using \bmod,
without changing any spacing (and making the code and generated output
slightly more efficient). In particular, fix#982.
* \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%
}}}
```
