We updated Gitter to use the latest katex@0.10.0, gitlab-org/gitter/webapp!1308
You can test it out on Gitter next/staging, https://next.gitter.im/ (part of Gitter 19.32.0)
If you see anything wrong, feel free to create an issue, https://gitlab.com/gitlab-org/gitter/webapp/issues
Hi, I'm trying to build KaTeX and it fails.
What I did is this:
git clone git@github.com:KaTeX/KaTeX.git
cd KaTeX/
npm install
npm run buildand the build output started as follows:
$ npm run build
> katex@0.10.1-pre build /home/username/KaTeX
> yarn prestart && rimraf dist/ && mkdirp dist && cp README.md dist && rollup -c && webpack
yarn run v1.13.0
$ yarn check && node src/unicodeMake.js
info fsevents@1.2.4: The platform "linux" is incompatible with this module.
info "fsevents@1.2.4" is an optional dependency and failed compatibility check. Excluding it from installation.
error "@babel/generator" is wrong version: expected "7.0.0", got "7.3.0"
error "@babel/helper-function-name" is wrong version: expected "7.0.0", got "7.1.0"
error "@babel/parser" is wrong version: expected "7.0.0", got "7.3.1"
...The same failure occurs when I run yarn build.
What am I doing wrong? I have node version v8.10.0, npm version 3.5.2, and yarn version 1.13.0. And current KaTeX commit is 7f778d1543fc1a9021609fa29067073658fb0d4b.
Hi, is there any idea when 0.10.2 will be released? KaTeX/katex-fonts#60 is pretty bad for us as safari users are being told that not equal things are actually equal! So a hotfix release with this in would be great. Thanks
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.
/snapshot/KaTeX/cli.js:18
throw e;
^
Error: Cannot find module './'
yarn build in turn fails with this
$ yarn build
yarn run v1.15.2
$ yarn prestart && rimraf dist/ && mkdirp dist && cp README.md dist && rollup -c && webpack
$ 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
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},
]}
);
