* \@binrel command and refactor
New `\@binrel{x}{y}` command renders `y` as if it's a bin/rel/ord like `x`.
This is equivalent to AMSTeX's `\binrel@{x}\binrel@@{y}`.
It will hopefully be useful for macros, such as `\pmb` (#1418).
Also refactor the (already duplicated) code for implementing this
functionality into buildCommon.binrelClass.
* Add tests; fix flow error
* Another test
* Move binrelClass to functions/mclass.js
* Remove expensive array destructuring polyfill
* Make MathNodeClass include documentFragment for ergonomics.
* Separate out the HTML and MathML documentFragments.
These two documentFragments have different additional properties/methodsi
and limitations. This separation is needed for porting buildMathML to
flow.
* Coalesce the documentFragment subclasses to avoid subclassing polyfill.
* Make DomSpan and SvgSpan type aliases again instead of subclasses.
* Remove type MathNodeClass in favor of MathDomNode.
* Resolve $FlowFixMes by reordering variants of a union type.
* \html@mathml
Fix#1452
* Add missing file
* Implement \char (via internal \@char)
* Remove excess <mstyle> wrapper on \mathbin etc.
* Fix tests
* Add Unicode support for \copyright and \textregistered
Testing that this doesn't lead to an infinite loop thanks to \char` escaping.
* Add tests
* Use assertNodeType
* Switch from regex to lookup table, and no parseInt
* Reset `supSub.value.base` after building `supSubGroup`
* Remove tree cloning before building HTML
`buildExpression` is no longer destructive, added comment regarding it,
* Support \genfrac and \above
* Accommodate delimiters inside groups
* Update screenshots take one`
* Update screenshots take two
* Fix flow error
* Fix lint error
Within a single call to `renderMathInElement`, default `macros` to a shared
empty object (same as if you specified an object) so that global macros
defined via `\gdef` can be defined and shared.
* Automatic mrel/mbin spacing for \boldsymbol
Fix#1154
* Add test
* Add missing mode
* Separate out \boldsymbol support to correct flow types
* Fix ternaries thanks to @ronkok's comment
* Revert package-lock.json
* Add screenshot test
* Add and expose addFontMetrics function
* fix typo
* recreate package.json-lock
* Add setFontMetrics function to change the defualt metricMap - change getFontMetrics to getGlobalMetrics
* use new setFontMetrics on main KaTeX object
* fix package-lock.json error by rebuilding it
* Add appropriate tests
* update the snapshot
* \newcommand, \renewcommand, \providecommand
* Tests
* Add comment
* Add symbols to the set of already defined things
* Add implicitCommands, catch \hline outside array
* Add \relax
* Move isDefined to be a method of MacroExpander
* Namespace.has
* Reword error messages
* Add \hdashline given #1407
* Support \hdashline
Support `\hdashline` from package `arydshln`. This PR acts as a complement to PR #1395.
Similarly to #1395, the dashed line is rendered as `border-bottom-style: dashed;`. That does not exactly match the `dashsegment` and `dashgap` lengths in `arydshln`, but it does render black lines with sharp edges.
* Fixed top line position
* Add screenshots
* Fix lint error
* Fix another lint error
* Deleted HLine screenshots
* Pick up comments
* Fix ligatures not always triggering
Example: \text{\rm --} would not cause ligature but should
* Remove ligatures in \texttt mode
* Add screenshot tests
* Fix MathML ligatures
* Fix type
* Handle \text... fonts in MathML building
* Remove leftover console deubgging
* Replace ParseNode<*> with a more accurate AnyParseNode and fix flow errors.
* Allow "array" environment type spec to use any all symbol type.
Before this commit, it was constrained to use "mathord" and "textord", but a
recent change in HEAD resulted in a "rel" node being used in the spec for, e.g.
\begin{array}{|l||c:r::}\end{array}
* Address reviewer comments: rename `lastRow` to `row` in array.js.
* hacked together a dashed vertical bar
* Updated tests and spec.
* tidied up the screenshot template for arrays
* added the vertical lines at the end back
* Updated screenshots for arrays
* Support \arraystretch as a macro definition
Also add `expandMacro` and `expandMacroAsText` helpers to `MacroExpander`.
* Remove excess defaulting
* Add test
* Fix \cancel
Fixes#1080.
Improve `\cancel` in three ways:
1. Better lateral spacing.
2. Steeper `\cancel` lines on single characters.
3. Treat height and depth to match the `cancel` package behavior, not its documentation.
* Update screenshots
* Support \cfrac
This was an easier PR to write than #135 since KaTeX now has well established methods for pt-to-em conversions and nulldelimiter.
As in #135, this does not support the LaTeX optional argument for numerator justification. It supports a `\cfrac #1#2 ` syntax.
* Added screenshotter files
* fix ref to context in genfrac handler
