A set of KaTeX macros that don't use a backslash could be written at
\gdef A{{\char65}}, \gdef B{{\char66}}, etc. If you don't want to write those macros into each document, you can write them in the rendering options
Also,
katex.js exposes the defineMacro function. So you could write your set of macros in a separate file. Say we call it frenchmath.js. That file would go into the same folder as katex.js. The HTML document would include in its <head> a line saying <script src="frenchmath.js"></script>, placed after the call to katex.js, and the french math file would contain a set of macros, each resembling: katex.__defineMacro("A", function(context) {
return "{\\char 65}"
});
Ah! I see now that the documentation for the rendering option mentions the single character use. This all looks perfect – except it seems I'm using KaTeX the wrong way, so I can't get any of this to work. I'm using the minified version, which I guess maybe means
https://xuc.me/blog/katex-and-jekyll/
I mean, it works for normal use, but the fact that I can't get the above things to work is probably a sign that I should be doing things differently :->
__defineMacro isn't available…? (At least I'm told it's not a function.) Trying to use \gdef inside formulas gives me an error, and the display options don't seem to do much. (The displayMode option, for example, doesn't change mode, so I've used \displaystyle as a workaround.) I'm using it with Jekyll and Kramdown, and essentially followed the setup here, which I guess may be not altogether sound:https://xuc.me/blog/katex-and-jekyll/

Eh … I realize I'm using 0.1.1, while the current version is 0.10.0 xD OK, I'll have another go.
Back with another question … I'm typesetting figures in TikZ and converting them to SVG (using
pdf2svg), and using them alongside KaTeX in the main text – and I haven't been able to figure out a proper combination of font sizes and scaling (in my TikZ/pdflatex) to emulate the look of KaTeX. It seems (for example) subscripts in KaTeX have the same design as normal-sized text, and are just scaled down? And beside that, everything looks more solid/black – and I don't think it's just a matter of SVG rendering (though I may be wrong).
(The scaling might not be perfect either, but that's easier to fix.)
In part, it does seem like the SVG rendering is too wispy, in and of itself – like, e.g., the capacities in these flow networks:
https://algdat.idi.ntnu.no/faq/2018/11/07/kapasitets-og-flytokning.html
https://algdat.idi.ntnu.no/faq/2018/11/07/kapasitets-og-flytokning.html
I've tried just using smaller font sizes (which tend to be blacker) and scaling them up (in the PDF/SVG), but then, of course, the letter shapes start looking a bit off.
Any thoughts of harmonizing the looks of the KaTeX math and the figures? (I could use a completely different, blacker font in the SVG, but that won't exactly make things more harmonious…)
In the browser, it is rendering fractions with an SVG element for the horizontal bar. In Node,
renderToText produces span elements with borders that wind up not being displayed correctly.
I have tested
renderToText in the console in the browser, and it produces the SVG version
input:
\frac{\mathrm{TP}}{\mathrm{TP}+\mathrm{FN}}

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.

yarn build in turn fails with this

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
