Important

This plugin was written for CodeMirror 5 and isn't compatible with CodeMirror 6 (which is the default since Joplin 3.1.x).
For the new CodeMirror version, I recommend this plugin: Extended Markdown editor settings

	Adds some CodeMirror options to Joplin's settings, such as line numbers and line wrapping.

	Built with:	generator-joplin
	Inspired by:	Joplin Line Numbers Plugin
	Other plugins by me:	Search & Replace, MultiMarkdown Table Tools

This is a simple plugin for Joplin that exposes some CodeMirror options to the user, such as line wrapping or line numbers.

Note: This plugin only affects the Markdown editor (CodeMirror), not the WYSIWYG editor (TinyMCE).

Development

Text from "generator-joplin"

This is a template to create a new Joplin plugin.

The main two files you will want to look at are:

• /src/index.ts, which contains the entry point for the plugin source code.
• /src/manifest.json, which is the plugin manifest. It contains information such as the plugin a name, version, etc.

Building the plugin

The plugin is built using Webpack, which creates the compiled code in /dist. A JPL archive will also be created at the root, which can use to distribute the plugin.

To build the plugin, simply run npm run dist.

The project is setup to use TypeScript, although you can change the configuration to use plain JavaScript.

Updating the plugin framework

To update the plugin framework, run npm run update.

In general this command tries to do the right thing - in particular it's going to merge the changes in package.json and .gitignore instead of overwriting. It will also leave "/src" as well as README.md untouched.

The file that may cause problem is "webpack.config.js" because it's going to be overwritten. For that reason, if you want to change it, consider creating a separate JavaScript file and include it in webpack.config.js. That way, when you update, you only have to restore the line that include your file.
