* Reset to leftmost spacing mode after newline
Newlines have class "mspace newline" but shouldn't be fully ignored:
they should reset the spacing mode back to "leftmost" so as to not
accidentally create trailing spaces at end of lines. Fix#1828.
* Update snapshots
* Add root detection, and treat newline specially only then

* Re-enable \includegraphics now that we have trust setting
This reverts commit 5806b240b3.
* Include Khan Academy test logo in repo and use in test (fix#1892)
* Update screenshots
* Update documentation
* Add tests, cleanup existing tests
* Update snapshots
* Enable trust testing (trust=true by default)
* Remove forced \normalsize in \raisebox
Fix#1786 (incorrect size of "E" in `\TeX`) by fixing `\raisebox` to
keep the current font size. Previously, `\raisebox` was rendering its
second argument as if it were in `\normalsize\textrm{...}`; now,
the argument is just as if it were in `\textrm{...}`.
* Fix screenshots
* New "hbox" argument type to convert box-like arguments
* Review comments
* Fix \fbox to use hbox argument
* Render A in \LaTeX and \KaTeX in \scriptstyle (not \scriptsize)
* Add screenshot test

* trust option to indicate whether input text is trusted
* Revamp into trust contexts beyond just command
* Document new trust function style
* Fix screenshot testing
* Use trust setting in \url and \href
* Check `isTrusted` in `\url` and `\href` (so now disabled by default)

doesn't need to be passed into every context.
* Document untrusted features in support list/table
* Existing tests trust by default
* remove allowedProtocols and fix flow errors
* remove 'allowedProtocols' from documentation

* default trust to false in MathML tests
* fix test title, remove 'trust: false' from test settings since it's the default
* Improve MathML for classes
* Fix lint errors
* Fix another lint error
* Simplify MathML resulting from single character box
* Fix lint errors
* make some of the arrays in our html/mathml helper functions readonly
* Remove double encoding in MathML via Unicode MathML spaces
We used to have a complex mechanic for escaping strings, marking them as
`needsEscape = false`, and then not escaping those strings (for
combining strings in `\operatorname`). But this doesn't really work
with `render`ing directly to a node, as `document.createTextNode` can't
be stopped from escaping.
I've thus removed this mechanic, which required the following changes:
* Switch MathML "smart space" encoding to use Unicode instead of
`&LongNames;` (which weren't working with `render` for the same reason).
* Hack our HTML/MathML serializer to not use `String.trim`, which wrecks
havoc with emitted Unicode spaces.
Now `toText()` doesn't escape, so strings concatenate in unescaped form,
and `toHTML()` only does the necessary escaping. Thus fix#1782.
* Fix src/utils.js
Co-Authored-By: edemaine <edemaine@mit.edu>
* Fix src/mathMLTree.js documentation
Co-Authored-By: edemaine <edemaine@mit.edu>
* Remove trim hack thanks to diffable-html@4.0.0
* Switch back to jest-serializer-html
* Update mathMLTree.js
* Fix \\ and \newline after operator
Fix#1790. `\\` and `\newline` render as a span with classes
`mspace` and `newline`. We need to check for `newline` when bringing
spaces into the same `base` group.
* Add tests and comment
* 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.
* 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
* 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`

* use new setFontMetrics on main KaTeX object
* fix package-lock.json error by rebuilding it
* Add appropriate tests
* update the snapshot
* 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 excess defaulting
* Add test
* 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
* Avoid unnecessary <mrow> wrapping
buildMathML gains two helpers:
* `makeRow` helper wraps an array of nodes in `<mrow>`,
unless the array has length 1, in which case no wrapping is necessary.
* `buildExpressionRow` for common case of `makeRow(buildExpression(...))`
* Combine adjacent <mtext>s in all cases
No more need for `makeTextRow` helper or anything fancy in text MathML handler.
* Concatenate <mn>s and decimal point into single <mn>
Fix#203

* Wrap tag in group so e.g. ( and ) are formatted the same
* Add `feed` method to MacroExpander for multiple inputs (for tag)
* Bug fixes in buildHTML, makeTextRow, _getBuilt (for display mode)
* Remove excess <mrow> wrapper when unnecessary
* Update screenshot from tag being wrapped in group
* Add maxExpand limit
* Move test helpers into common modules
* helpers.js gets all the helper functions

* @ylemkimon's comments: parsing -> building, settings || defaultSettings
* Default argument for settings
* Fix lint errors
* @ylemklemon's comment: use buildAndSetResult
* Use template literals
* Stop throwing ParseError when throwOnError is false
`render`, `renderToString`, etc. now catch ParseError and render it to the
raw LaTeX (with proper escaping) and a hover title with the error.
Along the way:
* Use new `katex.__renderToDomTree` in katex-spec's `_getBuilt`.
(This was necessary to get the new error handling in `_getBuilt`.)
* Fix jest results which must always be functions, not strings.
* fix lint
* Fix flow error
Leave error type unspecified, as we check it with instanceof.
* Update katex-spec.js
* update fonts and metrics so that accents are positioned correctly
* fix degree symbol, move more accents into the 0x2c0-0x2df range
* fix accents in Unicode screenshots
* update jest snapshots, update AccentsText to include requested characters
* update fonts submodule, add unicode chars to AccentsText test
* update submodules after merging its PR
* Unicode accents
* Lexer now looks for combining dicritical marks and adds them to the same character
* Parser's `parseSymbol` now recognizes both combined and uncombined forms of Unicode accents, and builds accent objects just like the accent functions
* Added CJK support to math mode (not just text mode)
* Add invalid combining character test
* Add MathML test
* Add weak support for other Latin-1 characters
This maintains backwards compatibility, but it uses the wrong font.
There's a TODO to fix this later.
Also refactor symbol code to use for..of
