* 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
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.
* Correct (type-wise) raisebox's usage of sizing's buildHtml.
* Move HTML and MathML groupTypes into defineFunction.
Currently, functions defined in functions/* import all exports from buildHtml
and buildMathML, but they should never use `groupTypes` directly as it loses
type-safety. They should instead use more type-safe `htmlBuilder`s and
`mathmlBuilder`s exported directly from other definitions `functions/*` to allow
flow to catch errors.
* Rename groupTypes to groupBuilders.
This is particularly important as update-sri.js only updates jsdelivr links.
I was able to get update-sri.js to do the heavy lifting (computing checksums)
after updating the links in general, and downloading v0.10.0-alpha from CDN.
* Move "supsub" handlers to functions/subsub.js.
* Add flow types to functions/supsub.js.
* Simplify getBaseElem's output type based on all existing uses.
Before supsub was ported to flow, it had an instance where it could pass a
nullable to isCharacterBox which would pass it into getBaseElem and receive a
false. The refactor and strict typing of supsub now ensures that only a
non-nullable value is passed in to isCharacterBox and getBaseElem.
* Remove warnings at the top of buildMathML and buildHTML.
* Fix silly mistake.
* Fix lap vertical alignment.
Fixes issue #1153.

* Update screenshots
* Update screenshots
* generated updated screenshots for Lap
* Change double strut to single strut
* Delete screenshotter test
* Add (commented out) test
* Fix mis-spelled word
* 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>

* @ylemklemon's comment: use buildAndSetResult
* Use template literals
Change symbol parsing to allow all Unicode symbols when the appropriate strict setting allows it. By default, this allows all symbols, but the user will get (probably two) warnings about them.
* 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
* Implement strict mode (replacing unicodeTextInMathMode)
Add new "strict" setting (default value false) that can take a boolean
(whether to throw an error or silently ignore), string ("ignore",
"warn", or "error"), or a function possibly returning such a value.
This enables a variety of ways of handling or ignoring transgressions
from "true" LaTeX behavior, making KaTeX easier to use while still
providing the ability for strict LaTeX adherance.
Resolve#1226, implementing that spec, for two existing
transgressions from regular LaTeX:
* src/functions/kern.js had some errors and warnings about use of
(units in) math vs. text mode commands.
* The former setting unicodeTextInMathMode (not in any released version)
needed to be set to true to enable Unicode text symbols in math mode.
Now these are controlled by the strict setting. By default, KaTeX is now
very permissive, but if desired, the user can request warnings or errors.
* Rewrite strict description
* Add tests for strict functions
* Stricter type for strict
* Switch default strict setting to "warn"
* Fix new flow error
* Fix another flow bug
* Support for top-level \newline and \\ in inline math
This was a little tricky because `\\` was defined as an endOfExpression.
Instead made `\\` a termination specific to an array environment.
Outside an array environment, buildHTML handles the `cr` object,
resulting in a `.newline` class. Currently this turns into a
`display: block` (with appropriate vertical spacing) only in inline math,
matching LaTeX.

Fix the vertical alignment so that it correctly takes into account the descender of the lower element.
Fixes issue 1303.
* Update screenshots
* Revert frac-lines to borders
This PR reverts the rendering of frac-lines from SVG paths back to span borders. This solves the thick grey bar reported by @mbourne in issue #1173.
The result is a frac-line similar to KaTeX v0.9.0-alpha1. The frac-lines are span borders and the CSS contains a `min-width: 1px;` rule to keep those borders visible.
There is one difference between this PR and v0.9.0-alpha1. The earlier work contained a second CSS rule:
```
@media screen and (-webkit-min-device-pixel-ratio: 2), screen and (min-resolution: 192dpi) {
.katex.mfra.fracline {
min-height:0.5px;
}
}
That second CSS rule did not help much. Instead, it caused some lines to disappear. In the thread to issue 1173, people tested the rendering from the proposed approach and reported that frac-lines disappeared only at sized that were already too small to read.

* Add `suppressBaseShift` to ParseNodeTypes
* Make ParseNode `value` payload type-safe.
* Make defineFunction handlers aware of ParseNode data types.
* Add `type` to all function definitions to help determine handler return type.
* Added unit test for case caught only in screenshot test and fixed issue.
* Rename some symbol `Group`s to avoid conflicts with `ParseNode` groups.
Symbol `Group`s are also used as `ParseNode` types. However, `ParseNode`s of
these types always contain a raw text token as opposed to any structured
content. These `ParseNode`s are passed as arguments into function handlers to
create more semantical `ParseNode`s with more structure.
Before this change, "accent" and "op" were both symbol `Group`s and `ParseNode`
types. With this change, these two types (the raw accent token `ParseNode`, and
the structured semantical `ParseNode` are separated for better type-safety on
the `ParseNode` payload).
* stretchy: Remove FlowFixMe for a forced typecast that's no longer needed.
* Update texcmp
I found that the existing docker rules for texcmp did not make a working
installation of LaTeX; in particular, it was missing a lot of the recently
added packages. I updated to Ubuntu 17.10 and tweaked the package listings
until things compiled again. Now I can run texcmp again.
* texlive-font-utils not necessary
