Hugo codeblock highlight

Hugo highlight plugin

This is a plugin for Obsidian, which highlights lines in code blocks using the same syntax as Hugo.

Usage

Add the hl_lines option after the language like this:

```js {hl_lines=[1]}
let a = 1;
let b = 2;
```

hl_lines can be a single number, or an array of numbers/ranges (hl_lines=[1, "2", "3-5"])

You can also select lines you want to highlight inside codeblocks and click Highlight selected lines in the right-click menu:

Only the hl_lines property is supported.

[!NOTE]
Currently, the plugin only works in 'Live Preview' or 'Source mode'. Reader mode uses a different html presentation & syntax highlighter, which are harder to support.

Developing this plugin

• Install dependencies: pnpm install
• Compile & watch changes: pnpm dev
• Build production release: pnpm build

Check the Obsidian documentation for more information.

Releasing new releases

• Update your manifest.json with your new version number, such as 1.0.1, and the minimum Obsidian version required for your latest release.
• Update your versions.json file with "new-plugin-version": "minimum-obsidian-version" so older versions of Obsidian can download an older version of your plugin that's compatible.
• Create new GitHub release using your new version number as the "Tag version". Use the exact version number, don't include a prefix v. See here for an example: https://github.com/obsidianmd/obsidian-sample-plugin/releases
• Upload the files manifest.json, main.js, styles.css as binary attachments. Note: The manifest.json file must be in two places, first the root path of your repository and also in the release.
• Publish the release.

You can simplify the version bump process by running npm version patch, npm version minor or npm version major after updating minAppVersion manually in manifest.json. The command will bump version in manifest.json and package.json, and add the entry for the new version to versions.json
