## How to build KaTeX for Discourse
|
|
|
|
|
|
|
|
|
|
1. `git clone https://github.com/KaTeX/KaTeX.git && cd KaTeX`
|
|
|
|
|
|
|
|
|
|
`git submodule update --init --recursive`
|
|
|
|
|
|
|
|
|
|
2. Disable TTF fonts:
|
|
|
|
|
|
|
|
|
|
`export USE_TTF=false`
|
|
|
|
|
|
|
|
|
|
3. Run build to fetch the fonts into `dist/fonts/`
|
|
|
|
|
|
|
|
|
|
`npm run build`
|
|
|
|
|
|
|
|
|
|
4. Copy fonts to this plugin
|
|
|
|
|
|
|
|
|
|
`cp dist/fonts/* discourse-math/public/katex/fonts/`
|
|
|
|
|
|
|
|
|
|
5. Change paths to fonts ((otherwise the fonts won't load in Discourse):
|
|
|
|
|
|
|
|
|
|
`sed -ri 's/@font-folder.+$/@font-folder:
|
|
|
|
|
"\/plugins\/discourse-math\/katex\/fonts";/'
|
|
|
|
|
submodules/katex-fonts/fonts.less`
|
|
|
|
|
|
|
|
|
|
3. Build KaTeX:
|
|
|
|
|
|
|
|
|
|
`yarn && yarn builld`
|
|
|
|
|
|
|
|
|
|
4. Copy `katex.min.js` and `katex.min.css` from `dist/` to
|
|
|
|
|
`discourse-math/public/katex/`
|
|
|
|
|
|
