Upgrade match-at and flow versions to resolve the match-at flow
errors, allowing us to remove match-at from the .flowconfig ignore
Test plan:
run `jest` and get the following output:
PASS test/unicode-spec.js
PASS test/errors-spec.js
PASS test/mathml-spec.js
PASS test/katex-spec.js (5.104s)
run `flow` and get:
No errors!
Summary:
Now that we're using ES6 import statements in our source code
it makes it difficult for people to consume the katex package
as a node module unless they're using node.js version 8.x.
This diff points the node entry to dist/katex.js which
is the compiled version of katex.js.
Test Plan:
- publish
- create a new project node project and add the new npm katex package as a deep
- require katex in a test file and run it using node.js version 6.x

This diff extracts MathML builder tests out into a separate file and
updates them to use jest snapshot testing. It updates the output of
prime ' from using identifier nodes <mi> to operator nodes <mo>. It
also updates large operators with limits to use munderover instead
of msupsub. I added an option to remove unnecessary mrows to buildGroup.
Right now it's only used for by groupTypes.supsub. I'll see if it can be used
elsewhere (everywhere?) in a follow up PR.
Test Plan:
- make test w/o errors
- verify mathml snapshots contain the desired markup
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
* Add babel transform-class-properties to have static class properties
* Upgrade Lexer and Parser files to use ES6 classes
* Update eslint max line length to 90 character (more indent because of using ES6 classes)
* Upgrade eslint and jasmin to support ES stage-2 features
* Use static properties to place constants near their functions
* Migrate all remaining sources to ES6 syntax
* Increase eslint max line length to 84
* Remove non-babelified endpoint in dev server.js
* Clean up server.js functions after removing browserified
* Make screenshotter not to use babel endpoint as we babelify everything now
* Ship predefined macros with the library, in macros.js.
* Allow macro arguments #1 and so on, with argument count deduced from string.
* Use these features to implement \overset and \underset, fixes#484.
This is motivated by the recent switch to Express 4.
Without this commit, “make serve” will print the following message:
Error: Most middleware (like logger) is no longer bundled
with Express and must be installed separately. Please see
https://github.com/senchalabs/connect#middleware.
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.
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.

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.
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.
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.
The combination of jspngopt and pako should eliminate possible causes for
different PNG encodings, although the core reason for #325 remains unknown.
Pako has poorer compression rates than native libz, but optimization can
counter that effect, and actually reduce the size of the screenshots.
The screenshots for LimitControls and UnsupportedCmds on Firefox used to
exhibit subpixel rendering before, for reasons unknown. The regenerated
versions don't exhibit this. See #324 for a discussion.
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.
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.
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.

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 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...)
