Buidler-ast-doc

Quickstart

npm install buidler-ast-doc

Add this to your buidler.config.js:

const { usePlugin } = require("@nomiclabs/buidler/config");

usePlugin("buidler-ast-doc");

module.exports = {
  // All fields are optional,
  // path defaults to cache path
  // file defaults to ast-doc.json
  // ignores nothing by default
  astdocs: {
    path: "./ast-docs",
    file: "ast-doc.json",
    ignores: "test"
  }
  // ...
};

npx buidler compile

What does it do

Parses the AST to generate (richer) documentation.
