StippleLatex uses Vue-Katex to imlement LaTeX-Formatting in Stipple. There are three possibilities of entering LaTeX content in your web page
-
Latex-span element.
latex(<LaTeX formula>, <formatting options>)
-
HTML element with latex content via string macro with an optional modifier which can take the values
auto
ordisplay
span(latex"<LaTeX formula>")
span(latex"<LaTeX formula>"display)
-
HTML element with latex content via
@latex
macro with additional optionsspan(@latex(raw"<LaTeX formula>")
span(@latex(raw"<LaTeX formula>", display = true)
All arguments also support Symbols to bind to model fields. Here's a demo app that shows possible use cases.
