jupyter-retext-language-server

A retext language server for Jupyter LSP. This builds upon the unified-language-server by exposing a simple configuration mechanism.

Plugins

By default, the jupyter-retext-language-server ships with pre-installed with the retext-spell plugin out of the box.

Extending

New retext plugins can be defined through Python entry points, e.g.

[project.entry-points.jupyter_retext_language_server_plugin_v1]
retext-spell = "jupyter_retext_language_server.plugins:retext_spell"

The retext_spell name in the jupyter_retext_language_server.plugins module has the following form:

Entry points

retext_spell = {
    "path": /path/to/retext-spell.mjs",
    "properties_schema": {
        "retext.plugins.retext-spell.enabled": {
            "type": "boolean",
            "default": True,
            "description": "Enable retext-spell plugin.",
        },
        // ... etc
    }
}

It is through this entry point that the settings schema and path to the ESM module can be defined.

ESM plugin

The ESM plugin exposed by the Python entry point must define two named exports, e.g.

export const name = "retext-spell";

export async function plugin(spellConfig) {
  // Plugin impl
  return (tree, file, next) => {};
}

These define the name (which maps to the plugin name in the properties schema), and the plugin implementation that is invoked by the plugin manager.

Future development ideas

• Generalise the project to allow multiple ecosystems (unified, retext, etc).
• Add proper schema merging.
• Validate plugin subschemas
• Validate plugin ESM modules
• Implement upstream fixes to expose the config — https://github.com/unifiedjs/unified-language-server/issues/69
