Tips and tricks for Hugo/PaperMod that I have used.

Opening Links in New page

Override default behaviour by adding a render-link.html file under layouts. Follow this page for more details.

Handle Katex

  • Enable Maths on the markdown page:
1
2

math: true
markup: "mmark"
  • Create a shortcode for katex with {{ .Inner }}. This would ensure all text meant for Katex is not processed.
  • Use shortcode \{\{< katex >\}\} before any katex code.

\{\{< katex >\}\} # remove \ here
$$  
\begin{align} 
q(x_t|x_0) &= N(\sqrt\alpha_tx_{t-1}, (1 - \alpha_t )I) \cr   
&= \sqrt\alpha_t x_{t-1} + \sqrt{(1-\alpha_t)}\ast\epsilon_t \cr   
&= \sqrt\alpha_t(\sqrt\alpha_t x_{t-2} + \sqrt{(1-\alpha_{t-1})}\ast\epsilon_{t-1}) + \sqrt(1-\alpha_t)\ast\epsilon_t \cr  
&= \sqrt\alpha_t\sqrt\alpha_t x_{t-2} + \sqrt\alpha_t\sqrt{(1-\alpha_{t-1})}\ast\epsilon_{t-1} + \sqrt(1-\alpha_t)\ast\epsilon_t \cr

&= ... \cr

Adding collapsible Sections in Hugo

Got this from here

The following caveats:

  1. Have an empty line after the </summary> tag or markdown/code blocks will not render.
  2. Have an empty line after each </details> tag if you have multiple collapsible sections.

<details>

  ### Heading
  1. Foo
  2. Bar
     * Baz
     * Qux

  ### Some Code
  ```js
  function logSomething(something) {
    console.log('Something', something);
  }
