* Define the nested version of ParseNodes structs explicitly.
Passes test:jest, but fails test:flow.
* Fix additional type errors reported by flow.
* Migrate rebased code from master.
* Rename ParseNode.js to parseNode.js.
* Update defineEnvironment output type to fix the flow errors in environment/array.js.
* Comments without terminating newlines in nonstrict mode
Fix#1506 by allowing single-line comments (`%` without terminating newline)
in nonstrict mode. `Lexer` and `MacroExpander` now store the `Settings`
object, so the `Lexer` can complain about missing newline according to the
`strict` setting. I filtered this out from the snapshot tests with a slightly
different `replacer`.
* Reimplement \href like \verb, add \url
Major restructuring to lex URL arguments differently, e.g. to support
`\href%{hello}` and `\href{http://foo.com/#test%}{hello}`. The new URL
parsing code is simpler, but involves a special case in `parseSymbol`
like `\verb`.
Also add support for `\url` while we're here.
* Cleanup
* Fix flow errors and improve error messages
* Add \url to documentation
* Improve doc formatting
* Fix \not vertical alignment
Fix#1491 by changing from `position: absolute` to `position: relative`.
* Switch to \rlap implementation of \not
* Separate \not the macro from \not the symbol via \@not
* Fix test
* Support \pmb
* Fix lint error
* Add phony screenshots
* Screenshots take two
* Screenshots take three
* Simplify copies
* Move determination of mclass from handler to htmlBuilder
* Change to a macro definition
* Update screenshots
* Pick up review comments
* Clean up nesting of braces
* Update screenshot
* \@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
* 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
* Rewrite spacing commands as macros
Fix#1130 by defining `\!`, `\negthinspace`, `\,`, `\thinspace`, `\:`,
`\medspace`, `\;`, `\thickspace`, `\negmedspace`, `\negthickspace`,
`\enspace`, `\enskip`, `\qquad`, `\quad` as macros.
Fix#1036 by defining a new `SpaceNode` in mathMLTree that recognizes
all special space amounts from
https://www.w3.org/TR/2000/WD-MathML2-20000328/chapter6.html
* Fix <mspace> rendering and add a test to catch it
* Update screenshots
* Wrap special space characters in <mtext>
* Update screenshots
* Fix MathML escaping behavior
* Fix flow typos
* Fix Unicode-chrome
* Reimplement mod operators in terms of macros
* Rerun ModScript
* Remove excess table entries (now already macros)
* Fix bmod
* Nested environments of macro definitions
* Rename environment -> namespace
* \def support
* Clean up \df@tag at beginning
* \global\def support
* Fix \global via new setMacro helper
* Fix caching behavior and build array on top of it
Also avoid double lookup of macros
* Add tests
* Add argument tests
* Remove global pointer
* Note about macros object being modified
* add __defineMacro
* Add \global\def test
* More \global tests
* Constant-time lookup
Rewrite to use an "undo" stack similar to TeX, so get and set are
constant-time operations. get() still has to check two objects: one with all
current settings, and then the built-ins. Local set() sets the current value
and (when appropriate) adds an undo operation to the undo stack. Global set()
still takes time linear in the number of groups, possibly changing the undo
operation at every level.
`Namespace` now refers to a space of things like macros or lengths.
* Add \def to-dos
* Put optional arguments in their own group
* Rename `pushNamespace` -> `beginGroup`
* Wrap each expression in a group namespace
* Add comments
