Summary: IE 9 doesn't like trailing commas. When we introduced eslint, we added
a bunch of trailing commas, which makes IE 9 sad.
Test Plan:
- `make lint`
- Visit http://localhost:7936/ using IE 9 on browserstack.
- See that the math loads, and there are no errors in the F12 developer tools.

* Exit cleanly after invalid screenshot test name
This avoids waiting forever.
* Auto-detect host IP in Docker for Mac environment
This checks all available network addresses to find one which the Selenium
container can connect to. That way we don't have to analyze network
settings or similar to figure out the main public IP address of the machine.
* Make server less sensitive to current working directory
That way it becomes possible to run screenshotter.js from within the
Screenshotter directory, and still server all files as intended.
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

This fixes a problem where the graceful-js dependency of the old less
version is incompatible with node 7, and will cause warnings on node 6.
The resulting katex.min.css is exactly the same as with the previous
version, so the major version upgrade does not seem to affect the outcome.
The less.Parser has been deprecated, and less.render is the supported
approach now, so we have to switch the development server to that.
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.
Test Plan:
- ka-lint src
- make lint
- make test

Instead of having our own copy of jasmine in the repository, we use
jasmine-core as an npm dependency and load it from there. That reduces the
size of the repository and helps keeping up to date. We're not using the
transitive dependency on jasmine-core via jasmine, since the jasmine package
might change its dependency any day (although unlikely).
The katex-spec.js shipped from the server now includes all
`test/*[Ss]pec.js` (as matched via glob) so that additional spec files can
be created and will automatically get included in the browser-side test
suite. The contrib specs are not included at this point.
Visit http://0.0.0.0:7936/test/test.html while running server.js to see this
in action and verify the lack of failures.
This avoids one of the few requirements we have left: you no longer have to
start a KaTeX development server, the script will do it for you, using a
random port number.
To reproduce the old behaviour, explicitely state --katex-port=7936.
Summary:
Make the lint checker check more files. Also, make arc run the
linter.
Test Plan:
- `arc lint`
- `make lint`

Summary:
Add an auto-render extension to render math on a page. It
exposes a global function (maybe we should attach it to `katex`?) to
render math in an element. It comes with a README on how to use it.
Also, make `make build` build the minified file.
Fixes#26
Test Plan:
- Visit http://localhost:7936/contrib/auto-render/
- See that all of the math renders correctly
- `make test`

Summary:
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.
- Ensure that the huxley screenshots haven't changed
- Ensure that the build step still works

Move dom creation into katex.js so our tests can test non-dom things, and add
some buildTree tests. Add some checks make utils.js work in node. Add support
for jasmine-node, to allow for command line unit testing.

Summary:
This diff does a couple different things:
- There is now a metrics/ folder, which contains the property files describing
the metrics if the fonts, as well as a script for reading and printing the
metrics in javascript.
- Fractions and superscripts/subscripts are now rendered in slightly different
ways now (notably, no use of inline-table). This allows for much more precise
positioning of the superscripts, subscripts, numerators, and denominators,
while still having an appropriate baseline. Also, there is no longer a
sup/sub/supsub distinction, there are only supsubs with null sup/sub.
- Using the new font metrics and by implementing the formulas found in The TeX
Book, Appendix G, the heights and depths of all of the sub-expressions in a
formula are now calculated. These are currently used to:
- Correctly position superscripts, subscripts, numerators, and denominators
- Adjust the height and depth of the overall expression so it takes up the
appropriate space
- Because we have to add attributes (height and depth) to every attribute, I
have changed the way DOM nodes are assembled. Now, instead of assembling the
DOM elements inline (which is a problem because we need to track
height/depth, and we shouldn't (and can't in IE 8) attach raw attributes to DOM
nodes), we assemble a pseudo-DOM structure with the extra information, and
then actually assemble it at the very end.
The main page also now has an updated expression to show off and test the new
and improved parsing.
Test Plan:
View the main page, make sure that the expression renders. Make sure
that the tests pass. Make sure that expressions have the correct calculated
height (this is most easily tested by viewing them on the main page and making
sure that the top of the expression lines up with the bottom of the input box).
