53203ed92c Add a screenshot test to ensure that we don't inherit svg-only CSS properties (#1092)
We want to inherit CSS properties that apply to both text and SVG
but we don't want to inherit styles that affect SVG without affecting text.

This patch adds a screenshot test to verify this.

5f32b71c85 Use webpack to build files and webpack-dev-server for testing (#1068)
* Create a separate entry point for webpack

Created a webpack entry point for KaTeX, which imports katex.less. As
flow[1] and jest[2] doesn't support CSS modules natively, a separate
entry point is used and it is not flowtyped.

* Use webpack to build files

* Made webpack.config.js export valid webpack configuration
* Use:
browserify -> webpack
babelify -> babel-loader
UglifyJS CLI -> UglifyJsPlugin
Less CLI -> less-loader
cleancss -> cssnano in css-loader
build/fonts -> file-loader
* Inline CSS(Less) using style-loader and export them using
ExtractTextPlugin
* Add `watch` npm script calling `webpack --watch`

* Improve local testing(webpack-dev-server)

* Made webpackDevServer export a valid webpack configuration
* Compile Less and inline CSS using less-loader and style-loader
* Instead of copying files serve files from /static and use file-loader
* Remove old server.js and its dependencies

* Use webpack-dev-server in Screenshotter

* Include contrib in webpack-dev-server

+ Moved common configurations to webpack.common.js

* Rename webpackDevServer.js to webpack.dev...

to be consistent, avoid confusion with webpack-dev-server and follow
webpack configuration naming convention.

* Remove unnecessary conditional output.path

* Use map instead of reduce

+ Add comments regarding function arguments

* Remove unnecessary mkdir and clean build/* before build

* Use katex as external dependency instead of global variable in contrib

Fixes #692.

* Unblock codes as they are built as a module

* Update package-lock.json

* Add comments regarding devServer option

* Lint renamed webpack.dev.js

a0d8b33

* Export ES6 module and expose its default export

* Revert "Browserify hotfix (#1057)"

This reverts commit f6b509123b.

* Enables colors on the console when running the dev server in Screenshotter

* Add context to webpack configuration

Allows webpack to be run from other directories

* Move `rm -rf build/*` to npm scripts

* Check dependencies before build

* Move UglifyJsPlugin into config creation

* Let webpack handle ES6 modules

Do not transform modules to commonjs in Babel. However Jest doesn't not
support ES6 modules, so transfrom modules to commonjs when NODE_ENV is
`test`.

* Add documentation on testing in IE 9 and 10 using webpack-dev-server

Changed version range to include IE-compatible version

d93a958379 Make KaTeX work in Quirks mode (#608)
* Make KaTeX work in Quirks mode

Summary: In issue #601, it was noticed that the KaTeX bug with the fraction
bars overlapping the text was occuring with an XHTML doctype. This indicated
that the bug we were seeing was caused by both quirks mode and limited-quirks
mode (which is a version of quirks mode with fewer quirks and is enabled for
various doctypes including some XHTML ones).

Based on the [quirks spec](https://quirks.spec.whatwg.org/), it appears that
there are only two quirks in limited-quirks mode, both having to do with a
line-height calculation. @gagern figured out that if we added some zero-width
spaces in our elements, we would stop triggering the quirk, which would make
our fractions render correctly in limited-quirks mode.

I implemented that change, and ran the screenshotter in limited-quirks mode.
There were several other places that suffered from the same quirk, but were
also easily fixed via adding zero-width spaces. I then ran the screenshotter in
quirks mode, and discovered that (once an appropriate meta charset was added),
everything looked correct still.

So, this diff fixes all of the places that the limited-quirks mode quirks
affect our rendering, and removes the warning about rendering in quirks mode.

I also added support to our screenshotter to render things in both no-quirks
and quirks mode, to ensure that things don't break in the future. I copied the
non-quirks images to the quirks images, and ran the screenshotter with
`--verify` to make sure that they look the same.

I have some thoughts that I'd like to hear opinions about:
 - I'm not super happy with how the screenshot tests work. Ideally we'd test
   both quirks mode and non-quirks mode against the same images, since we'd
   like them to be the same. I'm not sure how to make that work well, though,
   since then people wouldn't be able to tell if it's a quirks-mode problem or
   not.
 - I removed the doctype in the testing page file, so all testing would now be
   done in quirks-mode. Not sure if we really want that.
 - I need to test this in IE, but it looks like the trailing commas change we
   made with eslinting is causing problems (cause IE doesn't like trailing
   commas).

Test Plan:
 - `./dockers/Screenshotter/screenshotter.sh --verify`

* Compare quirks mode against same screenshot files

Now the screenshotter itself can run more than one mode.  It does serve the
HTML file from its own JavaScript code now, so that it can include different
doctype headers without needing distinct files for each.  There is a
provision to mark specific tests as quirky in case they produce different
results depending on the mode.

* Some cleaning up and comments

* Restore access to the babelified version of the HTML page for screenshots

* Reference unicode fonts using absolute path names

This avoids issues caused by the fact that the dynamically generated
ss-render.html is mounted to a different location than the test.html from
which it is derived.

* do chrome screenshots first

* remove commented out code, simplify hadle_search_string call

1704d3b003 Speed up screenshot by avoid a full page + asset load for each test
The slowest part of screenshotter tests is the page load, probably
because so many assets must be loaded over the slow docker
connection. On my laptop this takes ~4s per test. The new default
avoids this cost by rendering new TeX on the existing
page. For second and subsequent tests, use `executeAsyncScript`
to call KaTeX, rather than performing a full page + asset load.
(If too many errors happen in `--verify` mode, we fall back to
full loads.)  The `--reload` flag will enable the previous behavior.

On my laptop, a full verify (chrome + FF) used to take 12m20s+.
It now takes 2m23s, a speed up of 6x.

38ba9f9187 Serve files with and without babelify step
As babelify is slow, it may be desriable to not run it during development.
This is OK if the browser is recent enough to understand ES6 natively.
(This does not include current Firefox due to it having problems with
for(const … in …), https://bugzilla.mozilla.org/show_bug.cgi?id=1094995.)
For older browsers, or to check issues possibly introduced by babelify,
adding /babel as the first component of the path will switch to a version
which has been processed by babelify.  This is also used for screenshots.

ec62ec39d8 Add support for Latin-1, Cyrillic, and CJK characters inside \text{} (#508)
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

d6cec8a861 Rename breakOnUnsupportedCmds to throwOnError.
Also, the MathBb-chrome test changed, to what I believe is the correct
result? Not sure why it looked wrong before.

Test plan:
 - `make test`
 - take screenshots, see nothing changed.

fb403fa9eb Switch Screenshotter data from JSON to YAML
Escaping TeX in JSON as query strings is a pain: you have to double all the
\\, you have to escape the & and the #, you can't easily include line breaks
for readability, and so on.  YAML solves most of these problems for most of
the situations.  Now each test case can be structured, while simple test
cases only consist of a line of verbatim TeX code, with no escaping.

The most troublesome items remaining are lines starting in { since in YAML
these would denote inline mapping types. We use block notation for these.

5d155c75db Switch from own docker image to standard selenium images
Since the Selenium images are available for download, and downloading them
is usually faster than building them from scratch, this makes taking
screenshots easier.  Furthermore, since the Selenium image is not specific
to KaTeX, it could as well be used for other purposes, thus saving space
since a single image can be used in multiple projects.

This change also deals with the non-determinism in the Lap screenshot:
We detect the one known (and accepted) alternate rendering and change the
output file name to Lap_alt in this case.  So either Lap or Lap_alt gets
saved to, and if the image is different from both, then one of these files
will show a modification.  On the other hand, if it is equal to either of
these, then the matching one will get overwritten, showing no change.

2f552af02d Make our own screenshotting script instead of using huxley
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...)
