buidler-ast-doc
Advanced tools
A buidler plugin to generate richer documentation for your solidity contracts
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
Parses the AST to generate (richer) documentation.
Data is serialized in a JSON blob, e.g.
