See nlcst for a list of utilities that work with the syntax tree. See unist for other utilities which work with nlcst and other syntax trees too. Finally, see vfile for a list of utilities working with virtual files.

To use a plugin programmatically, call the use() function.

To create a plugin, first read up on the concept of plugins. Then, read the guide on “Creating a plugin with unified”. Finally, take one of existing plugins, which looks similar to what you’re about to make, and work from there. If you get stuck, discussions is a good place to get help.

You should pick a name prefixed by 'retext-' (such as retext-emoji). Do not use the retext- prefix if the thing you create doesn’t work with retext().use(): it isn’t a “plugin” and will confuse users. If it works with nlcst, use 'nlcst-', if it works with any unist tree, use unist-util-, and if it works with virtual files, use vfile-.

Use default exports to expose plugins from your packages, add retext-plugin keywords in package.json, add a retext-plugin topic to your repo on GitHub, and create a pull request to add the plugin here on this page!
