tern-local-scope-condense-plugin

A tern plugin for including local scope entries in condenser output.

The tern condenser is designed to "condense" a set of JavaScript files into a concise and type-inferred description of their public API. It doesn't include local variables or any other entries not reachable by an external caller.

This plugin hooks into the condenser to output such information. It's useful if you wish to have a near-complete representation of the structure of a JavaScript program, for static analysis tools (such as Sourcegraph).

Usage

To install dependencies, run npm install.

With the tern condenser

Load the plugin:

$ node_modules/tern/bin/condense --plugin local-scope-condense testdata/simple.js
