417383e002 Rewrite spacing commands as macros (#1156)
* 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

acccce801d \def support (and \gdef and \global\def) (#1348)
* 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

2974639877 Fix coloneq etc (#1372)
Fix issue #1333.

`\coloneq` and several similar functions are written as macros. When expanded, these result in atoms like ":" and "=" placed adjacent to each other at the top level. So they exposed to a split by an automatic line break.

This PR wraps each of these macros in an `\mathrel{ }`. This prevents the line break.

1ed99d9ff3 Strict setting controls \newline display-mode behavior; fix MacroExpander space handling (#1314)
* Strict setting controls \newline display-mode behavior

* Bug-fix space handling in macros

Whitespace after a \controlWord is now handled within the lexer, not by the
MacroExpander.  This way, \\ expanding to \newline doesn't accidentally
cause spaces to get consumed.

* Rename nonstrict -> reportNonstrict; strictBehavior -> useStrictBehavior

* Second category of errorCodes

7fec5ae5dc Fix \underset (#1277)
* Fix \underset

This PR modifies `\underset` and `\overset` to align with LaTeX behavior when a superscript is applied after the `\underset`.  Fixes issue #1275.

I also changed the spacing from KaTeX `mop` to KaTeX `rmel`. The result seems to be a closer visual match to LaTeX.

The lack of \aa and \AA was reported in #1066.  Added these
via simple macros, with supporting tests.  Also add \lq, \rq,
\lbrack, \rbrack as aliases for "`", "'", "[", "]" which were
in the same area of latex.ltx.

484d44ee70 Unicode accents (#992)
* 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

* Update Unicode screenshot

* Remove dot from accented i and j (in math mode)

Also add dotless Unicode characters to support some accented i's and j's

* Fix \imath, \jmath, \pounds, and more tests

* Switch from for..of to .split().forEach()

Save around 800 bytes in minified code

* Fix split

* normalize() detection

* Convert back to vanilla for loops

* Fix merge

* Move normalize dependency to unicodeMake.js

* Make unicodeSymbols into a lookup table instead of macros

This is important for multi-accented characters.

* Add comments about when to run

* Move symbols definition into unicodeMake/Symbols.js

* Remove CJK support in text mode

* Add missing semicolon

* Refactor unicodeAccents to its own file

* Dotless i/j support in text mode

* Remove excess character mappings

* Fix Åå in math mode (still via Times)

* Update to support #1030

* Add accented Greek letter support (for supported Greek symbols)

* Update screenshot

* remove Æ, æ, Ø, ø, and ß from math mode test

c30edaaf5b Implement \TextOrMath, \@secondoftwo (#1024)
* 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

  The latter work only in math mode and only support mu units.)

* 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
