I'm running into some issues
This appears to work
$ pkg cli.js
> pkg@4.3.7
> Targets not specified. Assuming:
node10-linux-x64, node10-macos-x64, node10-win-x64but then I get
$ ./cli-linux --help
KaTeX could not import, likely because dist/katex.js is missing.
Please run 'yarn' and 'yarn build' before running
cli.js from the KaTeX repository.

yarn build in turn fails with this

$ node src/unicodeMake.js
./katex.js → dist/katex.mjs...

Error: Could not resolve '../submodules/katex-fonts/fontMetricsData' from src/macros.js
I followed the instructions in katex-fonts, installed texlive, perl, JSON for perl , fonttools on python2.7 and now I'm stumped at this
$ sh buildMetrics.sh

I've just published 0.10.2. Please file issues in https://github.com/KaTeX/KaTeX/issues if you see any problems with the release.
@MadLittleMods thanks for upgrading KaTeX in gitter. 🙂
@mbarkhau I'm not familiar with
pkg. You might try changing the require("./") to require("./katex.js") or the path to the built files if that makes more sense for your purposes. To fix the issue with submodules see https://github.com/KaTeX/KaTeX/blob/master/CONTRIBUTING.md#working-with-submodules.
I want to implement in my application
here we need to implement in ckeditor
requirement is math equations, special characters, , images and text
actually we have implemented this, to execute this, we are using $ symbol before and after equations
we need without $ symbol
I am having the battle of my life trying to get auto-loader to work properly in my ember app
I'm wondering if anyone here's whether familiar w/ ember or not can help shed the light on what's going on
*auto-render
not auto-loader
Katex's auto-render ofc
Uncompiled it's
\begin{aligned}
\text{Combine like terms} \
10 & = y\
\text{Now add 3 to both sides and then do something else} \
3 + 10 & = y + 3
\end{aligned}
\begin{aligned}
\text{Combine like terms} \

i'm an actuary (and katex newby) and am interested in being able to use katex for actuarial symbols (see above). i don't see native support in katex, but found this library: https://ctan.org/pkg/actuarialangle which can do it. is there a way to have this library loaded into katex?
Hey Shaneleib, Katex is pretty limited when it comes to adding your own latex packages/symbols. My understanding is that you can't use a symbol unless it's explicitly supported: https://katex.org/docs/supported.html
Hi, at LMFDB we have a few pages with incredibly large math strings, such as http://beta.lmfdb.org/NumberField/47.47.6807739517051283990370106856968124192474229146184900948675688481754810058334971205734548194436392534997735758198660848138706901604387352879006731328411841.1 on these large strings KaTeX does not run, I was wondering if anyone knew the mechanism by this fails, and any way I could convince KaTeX to try really hard here or whatever? thank!
Is there any "for dummies" guide to KaTeX, starting with "here is where you put the stylesheet call" and extending through "here is how to enter an expression within, say, a paragraph (as a span); or on its own line (as a div)", including what is meant by "element" in "katex.render("c = \pm\sqrt{a^2 + b^2}", element, {throwOnError: false});" and whether a third argument (here, the "throwOnError" portion) is required? Thank you!
my current renderMathInElement is :
renderMathInElement(latexElementID,
{delimiters: [ // mind the order of delimiters(!?)
{left: "$", right: "$", display: true},
{left: "$", right: "$", display: false},
{left: "\\[", right: "\\]", display: true},
{left: "\\(", right: "\\)", display: false},
]}
);
[
\begin{bmatrix}
a & b \
c & d
\end{bmatrix}
]
\begin{bmatrix}
a & b \
c & d
\end{bmatrix}
]
I have no problem to display the matrix,
but add '% my comment' will be problem
Heya, quick question to devs familiar with KaTeX: if one wanted to convert KaTeX output into another markup than HTML, would it be best to work from the HTML generated (with all the <span>s), or would it be better to use some other internal structure of KaTeX? If the latter, is there a good place to start looking? And for the former, is there a good place to get an overview of all the different classes and styles that KaTeX might apply?
@lazingor There another option, which is to use the KaTeX's MathML output instead of it's HTML output.
Browser support for MathML is limited, for now, to Firefox and Safari. The Chromium browsers will support it later this year. So yes, if you need it now and you need positioning information, then MathML is not sufficient.
I only offer the MathML option because manipulation of the KaTeX HTML sounds like a daunting task and the KaTeX/KaTeX#376 is now over four years old.
