Configuration

For the userscript, you can find the configuration from monkey menu.

For the extension, you can open the options page by clicking the browser button.

Embed images

The script uses the following regular expression to detect images:

/^[^?#]+\.(?:jpg|jpeg|png|apng|gif|svg|webp)(?:$|[?#])/i

Source

Custom rules

A list of regex pattern that will be likified, which is aimed to linkify non-http links. For example:

magnet:\?xt=\S+
evernote:///\S+

Build the extension

Files inside dist-extension/ and dist/ are built from the src/ folder:

1. Install Node.js.
2. Run npm install to install dependencies.
3. Run npm run build to build the extension and the userscript.

Some sites are excluded by default

You can check the default exclusion list in package.json. The list is also used by the extension. However, since the list is written into the manifest directly, it is not configurable. Unlike the userscript which allows you to modify the list in the script manager.

File an issue if you think a site should be added/removed from the list.
