ox-hugo currently supports the following syntax for latex equations: - https://orgmode.org/manual/LaTeX-fragments.html - https://ox-hugo.scripter.co/doc/equations This syntax is supported by mathjax as is mentioned in the ox-hugo documentation. But quartz uses remark-math which has some issues with the \( \) syntax. See https://github.com/remarkjs/remark-math/issues/39 This change adds few more transformations to the OxHugoFlavouredMarkdown plugin, which makes a best effort conversion of this syntax into what the Quartz Latex transformer plugin supports. With these changes, the generated files show latex formatting with default quartz configuration. Sidenote on `\_` escape by ox-hugo: ox-hugo escapes, _ using \_, we match against it after we transform equations into what quartz supports($$ and $). This could be achieved using lookaround like regex as follows ```js (?<=(\$|\$\$)[\s\S]*) -> Positive lookbehind for $ or $$ \\_ -> Matches \_ (?=[\s\S]*(?:\1)) Positive lookahead for $ or $$ if matched const escapedUnderscoreRegex = new RegExp(/(?<=(\$|\$\$)[\s\S]*)\\_(?=[\s\S]*(?:\1))/, "g") ```` But since lookahead/behind can slow things down on large files, we just look up all equations with $ and $$ delimiters and then try replacing \_

[org-roam](https://www.orgroam.com/) is a plain-text personal knowledge management system for [emacs](https://en.wikipedia.org/wiki/Emacs). [ox-hugo](https://github.com/kaushalmodi/ox-hugo) is org exporter backend that exports `org-mode` files to [Hugo](https://gohugo.io/) compatible Markdown.
|
|
|
|
Because the Markdown generated by ox-hugo is not pure Markdown but Hugo specific, we need to transform it to fit into Quartz. This is done by `Plugin.OxHugoFlavouredMarkdown`. Even though this [[making plugins|plugin]] was written with `ox-hugo` in mind, it should work for any Hugo specific Markdown.

|
|
|
```typescript title="quartz.config.ts"
|
|
plugins: {
|
|
transformers: [
|
|
Plugin.FrontMatter({ delims: "+++", language: "toml" }), // if toml frontmatter
|
|
// ...
|
|
Plugin.OxHugoFlavouredMarkdown(),
|
|
Plugin.GitHubFlavoredMarkdown(),
|
|
// ...
|
|
],
|
|
},
|
|
```

## Usage
|
|
|
|
Quartz by default doesn't understand `org-roam` files as they aren't Markdown. You're responsible for using an external tool like `ox-hugo` to export the `org-roam` files as Markdown content to Quartz and managing the static assets so that they're available in the final output.

|
> While you can use `Plugin.OxHugoFlavoredMarkdown` and `Plugin.ObsidianFlavoredMarkdown` together, it's not recommended because it might mutate the file in unexpected ways. Use with caution.
