* 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

* Add accented Greek letter support (for supported Greek symbols)
* Update screenshot
* remove Æ, æ, Ø, ø, and ß from math mode test
* copy-tex contrib module

* Fix HTML handling, in particular for Edge
* Convert DocumentFragment to HTML directly (via children' outerHTML)
* Set HTML content *before* text content; Edge takes the last only
* Handle .katex-html and .katex-mathml separately
* Implement option 2: CSS user-select: all
Also fix auto-render.js build location
* Revise documentation according to @kevinbarabash's comments
* Split copy-tex.js into it + katex2tex.js
This supports re-use of code in a custom copy handler.
* Document custom copy handler
* Add missing file
* Added MathJax compatibility script
* Removed make integrity, which release.sh handles
* Renamed scripts
* Use katex.render (and options) instead of manually string munging
* Rewrote code based on feedback
* Renamed file correctly
* Extended README with an example of usage
* Removed CDN paths in place of an abstract path
* Revert "Removed CDN paths in place of an abstract path"
This reverts commit 857f8de2e449d9ac5a3d8eab5104dac561c533c4.
* Replace versions with `...`, with note to avoid confusing users
* Revert some `...` replacements to files that do exist.
* Use inline SVG for stretchy elements
Replace all background-images with inline SVG code.
Pros:
* `\color` works in all browsers, even IE/Edge
* Better printing
* Much simpler CSS
* No links to background-images
* No `mask`
* No browser-detection
* No external SVG files
* Faster first rendering
Cons
* No image caching
* Heavier HTML load
* Larger JavaScript file
* `\cancel` line is in `px` units, not `em` units
* Remove static/images from make file
* Change \cancel from px to em
* regenerate screenshots for functions using inline svg
Summary:
The reasons for switching to jest:
- easy snapshot testing so that we can easily verify the structure of the parse tree and MathML tree
- easy compilation of ES6 features for tests as we continue to expand our use of ES6
Test Plan:
- npm test
All these version ranges include the latest version at the time of this
commit, except for the selenium webdriver. There version 3 is incompatible
with version 2, and switching to a version 3 library appears to require
switching to version 3 docker images as well, which would entail using
different browser versions which in turn would lead to differences for a
large number of screenshots. That doesn't appear warranted at this time.
* Let git ignore .npm-install.stamp and dist
The former is created for most makefile targets after dependencies have been
retrieved. The latter is created by typical operations like “make” without
arguments or “npm install”. Having these around is to be expected.
Adding this to .gitignore should NOT affect npm packaging, since that is
based on a whitelist in package.json which does mention dist.
* Allow installing dependencies without actually building KaTeX
We have been using “npm install” to install dependencies, but since that
also does build KaTeX itself, it may fail if e.g. there are any style guide
violations. Now we only fetch dependencies but do not build KaTeX itself.
The make conditionals used here are not part of POSIX make but a GNU
extension. But we already use functionality not mandated by POSIX (namely
many of the functions like “wildcard”), so this should not make portability
any worse than it already is.
This adds a stamp file which is used to detect whether the `package.json`
file got updated since the last `npm install`. If so, `npm install` is run
again to update all modules to the version described in `package.json`.
This happens as a dependency of only those modules which actually need some
npm-installed module.
Setting the corresponding make variable to the empty string disables the
feature, which is used by the `make` invocation in the `prepublish` script
inside `package.json` to avoid infinite loops. It can also be used by
developers working in an environment with reduced connectivity, as long as
they know what they are doing.
Summary:
This diff provides support for Latin-1, Cyrillic, and CJK characters
inside \text{} groups. For Latin-1 and Cyrillic characters we use
glyph metrics from a glyph from Basic Latin that has roughly the same
bounding box. We use the metrics for a capital 'M' to approximate the
full-width CJK characters. Half-width characters are not supported yet.
Test Plan:
- make test
- make screenshots

Summary
We'd like contributors to use the same linter and lint rules that we use
internally. This diff swaps out eslint for jshint and fixes all lint failures
except for the max-len failures in the test suites.

Jasmine supports node these days, so there is no longer a need to use a
separate (and unmaintained) package to provide such bindings.
Making the switch exposed several misuses of the `toMatch` assertion in the
existing specification. Most of them were converted to `toEqual`, since
`toMatch` is only for matching against regular expressions.
Summary:
The ability to use pre-determined character widths will benefit alternative
layout engines such as gagern's canvas layout engine. I would also like to
experiment would using CSS transforms to absolutely position each glyph. This
diff adds a new make rule, make extended_metrics, which generates metrics that
also containing glyph widths.
Test Plan:
- run `make extended_metrics`
- verify that fontMetricsData.js contains entries with 5 numbers instead of 4

This will make reviewing modifications easier, since the affected glyphs
will be more readily visible in the diff.
The formatting tool was applied to the existing data, instead of
regenerating the data, so the semantic content should be unmodified.
This separates auto-generated code from manually created code.
We need a more recent version of browserify to directly require JSON.
Note that the data was copied, not recreated, so it has not been changed.
This addresses issue #301.
We now try whether there is an executable called python2, and if so,
use that in preference to python when executing the metric computation.
Furthermore, we allow the user to specify the path of the python binary
using the PYTHON variable of make, i.e. “make PYTHON=/foo/python2 metrics”.
The same test cases we use for our screenshots from Firefox are now also
being rendered by pdflatex, so the resulting images can be used as reference
for how things are supposed to look (if we concentrate on compatibility with
LaTeX). To make comparisons even easier, the differences between LaTeX and
Firefox snapshots are rendered in a visual way, using different colors.
Discussed in pull request #268.

Summary:
Create our own screenshotting script which takes screenshots. This
improves over huxley for a couple reasons:
- It makes the screenshots the correct size (for some reason, huxley struggles
with this).
- Its configuration matches more with what we want (we don't need multiple
screenshots or interaction, we just want a single static shot)
- It runs faster
I also changed the docs to reflect this change.
Test Plan:
- Make sure all of the tests that were in the Huxleyfile are now in ss_data.json
- Run the screenshotter docker
- Make sure all of the images look reasonable and don't change (except
sometimes the Lap test, which has some strange pixel-positioning
differences...)

Create a fonts.less file which generates identical css to fonts.css, but using
less rules to be more understandable and customizable. For example, add the
ability to change where the fonts directory is located (instead of mandating it
be located next to the less file), and add the ability to disable specific font
formats (like disable EOTs when IE8 support isn't needed).
Test Plan:
- Ensure that the test page and huxley page still work
- Ensure that the output of `./node_modules/.bin/lessc static/fonts.less` is
the same as the original css by running both through
`./node_modules/.bin/cleancss` and diffing them.

Summary:
Upon switching over from ttf metrics to TeX metrics, we lost metrics for a
couple of the characters that are dynamically generated by TeX. Thus TeX doesn't
have metrics for them, but our fonts do have the characters because the MathJax
scripts also dynamically build them. This adds the ability to extract metrics
from the generated font files so that we can use the generated characters
correctly. A better solution would be to dynamically generate the characters
ourselves, but that is much harder, and will be left to a future time.

- Make sure typing "\neq \cong \text{ }" produces no warnings in the console.
- Make sure huxley screenshots look the same

TeX ships with. Pull the mapping out of the MathJax-dev repo from makeFF to get
the correct mapping of metrics to font characters, and use our own tfm reader to
extract metrics out of the tfm files into a useable format. Add a README and
Makefile rule to make this process easier in the future.
Also remove the silly 0.05em we put on supsubs because our italic correction
works now.
