Zero-config Hardhat plugin to generate documentation for all your Solidity contracts.
- 🤪 Zero-configuration required
- ✅ Compatible with latest Solidity versions
- 🔍 Supports events, errors and external / public functions
- 📖 Default output to Markdown
- 🔧 Extendable using custom templates
First thing to do is to install the plugin in your Hardhat project:
# Using yarn
yarn add @primitivefinance/dodoc
# Or using npm
npm i @primitivefinance/dodoc
Next step is simply to include the plugin into your hardhat.config.js
or hardhat.config.ts
file:
// Using JavaScript
require('@primitivefinance/dodoc');
// Using ES6 or TypeScript
import '@primitivefinance/dodoc';
And you're done! Documentation will be automatically generated on the next compilation.
The only thing you have to do is to comment your Solidity contracts using NatSpec format. For example, given the following function:
/// @notice Does another thing when the function is called.
/// @dev More info about doing another thing when the function is called.
/// @param num A random number
/// @return A random variable
function anotherThing(uint256 num) external pure returns (uint256);
Dodoc will take care of everything and will generate the following output:
function anotherThing(uint256 num) external pure returns (uint256)Does another thing when the function is called.
More info about doing another thing when the function is called.
Name Type Description num uint256 A random number
Name Type Description _0 uint256 A random variable
Dodoc is compatible with all the NatSpec tags (except custom ones), and can generate documentation for all the events, custom errors and all the external / public functions.
Dodoc comes with a default configuration but you can still tweak some parameters. To do it, change your Hardhat config file like this:
import { HardhatUserConfig } from 'hardhat/config';
import '@nomiclabs/hardhat-waffle';
import '@nomiclabs/hardhat-ethers';
import '@primitivefinance-dodoc';
const config: HardhatUserConfig = {
solidity: '0.8.9',
dodoc: {
// Put your configuration here
runOnCompile: true,
testMode: true,
},
};
export default config;
Here are all the configuration parameters that are currently available, but as said above, all of them are entirely optional:
Parameter | Description | Default value |
---|---|---|
runOnCompile |
True if the plugin should generate the documentation on every compilation | true |
include |
List of all the contract names to include in the documentation generation. An empty array will generate documentation for all the contracts | [] |
exclude |
List of all the contract names to exclude from the documentation generation | [] |
outputDir |
Output directory of the documentation | docs |
templatePath |
Path to the documentation template | ./template.sqrl |
testMode |
Test mode generating additional JSON files used for debugging | false |
Dodoc integrates a super cool template engine called SquirrellyJS, allowing anyone to create new output formats easily.
You can checkout the default Markdown template to get some inspiration, as well as SquirrellyJS documentation to learn more about it. Feel free to be creative, any kind of output such as Markdown, HTML or even JSON is supported!
Once you're satisfied, simply refer to your template using the templatePath
parameter in your configuration and Dodoc will use it to output the documentation!
Feel free to open an issue if you need help or if you encounter a problem! Here are some already known problems though:
- Due to some technical limitations, the documentation of
private
andinternal
functions is not rendered - Functions that are not commented at all might not be rendered either
- Special functions such as
constructor
,fallback
andreceive
might not be rendered
