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.
* 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
* Associate font metrics with Options, not Style.
Font metrics are associated with a given font and size combination.
Before KaTeX understood sizing commands, sizes were associated with
a Style. That's not true now. So instead of `style.metrics`, use
`options.fontMetrics()`, since `options` knows the font and the
size.
This is a cleanup commit with no visible effects on most tests (there
could be some small effect on size + style combinations). It will
make other changes possible later.
* Fix interaction between styles and sizes by implementing styles as sizes.
Rather than having both `textstyle` CSS classes and `size5` CSS classes
affect the font size (and step on each other), implement sizes more the
way TeX does: a command like `\displaystyle` changes the current size.
This is actually a simplification, since now only `size` affects the size.
Simplifies CSS and computation. Many screenshotter tests change; they
change to be more like TeX. For instance, `\sqrt` fixes some
discrepancies in size treatment.
Also:
Remove the `Options.withX()` methods in favor of `.havingX()`, which
might return the same `options`.
Remove `Style.cls()` and `Style.reset()`.
Remove `Options.reset()`. You should never modify an `Options`; they
should change only by the `havingX()` methods.
* Implement TeX sizing for scriptsize/scriptscriptsize.
At every size level. Also make the sizes match TeX to the last decimal.
* Review comments.
* Show correct browser support
KaTeX runs in IE 9 but not in IE 8. This PR edits the README and
Contributing files to reflect that fact.
Resolves issue #377.
* Show correct browser support
KaTeX runs in IE 9 but not in IE 8. This PR edits the README and
Contributing files to reflect that fact and adds Edge to browser list.
Resolves issue #377.
* Update texcmp to ubuntu 17.04 and avoid mounted host directory
Switch to linux 17.04 in order to have a version of nodejs which understands
ES6 syntax, for the sake of a consistent codebase.
Avoid mounting the host directory, but use “docker cp” instead to transfer
files between host and container. This should avoid ownership and
permission issues.
Support macros with positional arguments.
Fix one overline example which caused LaTeX failure due to missing braces.
* Extract texcmp results as current user
This allows running the texcmp.sh script using sudo on afs.
* Change texcmp conversion to gray
As per #708, this should increase compatibility with older versions of
imagemagick, and might also do a better job of preserving the original sRGB
color space.
* Abandon tar and use plain docker cp instead
Thanks to Erik Demaine for suggesting this.
* Move npm install into creation of texcmp docker image
The previous code incorrectly implemented TeXbook rules. First off,
the font metrics at issue should be those for the superscript/
subscript style, not the main style. Secondly, the metrics should be
scaled by the font size.
This changes some screenshotter tests (and they look more like TeX
now).

As the dist directory isn't available on the original branch, we cant use
its files to update the SRI hashes. Checking out from the release tag is
therefore the better option. A checkout will automatically stage its files.
