- Here is how to build a version of KaTeX that works with gitlab.
-
- The problem is that the standard procedure for changing font location doesn't work for the empty string.
-
- 1. Clone KaTeX. Anything later than 4fb9445a9 (is merged into master) will do.
- 2. make (requires node)
- 3. sed -e 's,fonts/,,' -e 's/url\(([^)]*)\)/url(font-path\1)/g' build/katex.css > build/katex.scss
- 4. Copy build/katex.js to gitlab/vendor/assets/javascripts/katex.js,
-    build/katex.scss to gitlab/vendor/assets/stylesheets/katex.scss and
-    fonts/* to gitlab/vendor/assets/fonts/.
