* Remove redundant consumeSpaces()
- Spaces after command sequence are ignored in Lexer
- parseExpression consumes spaces in the math mode
* Add catcode to Lexer, move comment parsing back to Lexer
- Fix parsing a comment before a sup/subscript argument
- Fix parsing a comment before an expression
- Fix parsing a comment before or between \hline
- Fix parsing a comment in the macro definition
- Fix parsing a comment including a command sequence
* Update Lexer.js
* Update Parser.js
* catcode -> catcodes
* Add support for `\lparen` and `\rparen` delimiters.
* Add missing math delimiter. Fix alphabetic order.
* Add test.
* Add spaces between parenthesis and square brackets.
* Update comment for defineFunction handler.
* Rename .value to .text in all token-style ParseNodes.
* Rename symbolNode's .value to .text.
* Rename color-token's .value to .color.
* Fix roots

* Added a test in a craven gambit to get a green check mark
* Adjust small radicals
* Fix lint error
* Update screenshots
* 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
* Refactor test helpers
* Combine common codes from `parse` and `build`, and dispatch using
`Mode`
* Remove `toNotBuild` and `toNotParse` and use `expect.not`
* Remove `Warning` and instead mock `console.warn`
* Add `expect.toHavePassed` and check whether parse/build succeeded
lazily
* Improve failed test `message`:
- Use color
- Print stack traces(excluding internals)
- Print diff
- Follow jest matcher output style
* Update helpers.js
* Remove toBeTruthy checks
getParsed throws an error if parsing fails.
* Used tagged literals
* Use .toHaveLength
* Use tagged literals
* Use to{Build,Parse}Like where possible
* Remove compareParseTree
* Use snapshot where possible
* Join into one line where <88 chars
* Revert console.warn() to throw an error
Merge `expectToWarn` to `expectKaTeX`, like
`expect.toFailWithParseError`
* Remove call to console.warn from stack traces
* Fix merge errors
* Remove `getTree`
* Move `_getBuilt` into `getBuilt`
* Move default settings and tagging literal support in to `getParsed`
and `getBuilt`
* Remove stack traces clean-up
* Remove `toHavePassed` matcher
* Extract `expected` string construction into `printExpectedResult`
* \@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
* \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
* 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
* 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
* 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
* Make letter tests strict
The recently added rendering mode `strict:"warn"` will allow any Unicode characters to be accepted. We expect `strict: true` to be pickier than that.
This PR sets `strict: true` on tests in `katex-spec.js` that should enforce that pickiness.
* Pick up comments
* Fix import of strictSettings
* 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
