Natspec Smells

Just like code, documentation can smell too. Natspec Smells aims to help automatically identify missing or incomplete natspec.

What can it do?

• Verifies natspec for: constructors, variables, functions, ~~structs~~, errors, events, modifiers
• Finds misspelled or missing @param or @return's.
• Lets you enforce the need for @inheritdoc in public/external functions.
• Can integrate on your daily workflow, or just as a final check.

No setup usage

Want to quickly check if your natspec smells?

Just run:

npx @defi-wonderland/natspec-smells --include "src/**/*.sol"

[!NOTE] Remember to put quotes around the glob strings when using the include and exclude options.

Recommended setup

1. Install the package:

   yarn add --dev @defi-wonderland/natspec-smells

2. Create a config file named natspec-smells.config.js, you can use the following as an example:

   /**
    * List of supported options: https://github.com/defi-wonderland/natspec-smells?tab=readme-ov-file#options
    */
   
   /** @type {import('@defi-wonderland/natspec-smells').Config} */
   module.exports = {
     include: 'src/**/*.sol',
     exclude: '(test|scripts)/**/*.sol',
   };

3. Run

   yarn natspec-smells

Verify your natspec in CI

With the setup defined above, it's possible to invoke the executable from within a github workflow, as long as node.js is available in that environment:

    steps:
      - uses: actions/checkout@v3

      - name: Use Node.js
        uses: actions/setup-node@v3

      - name: Check natspec
        run: yarn natspec-smells

Options

| Option | Description | Required | Default | | -------------------- | ------------------------------------------------------------------ | -------- | ------- | | include | Glob pattern of files to process. | Yes | | | exclude | Glob pattern of files to exclude. | No | "" | | root | Project root directory. | No | ./ | | enforceInheritdoc | True if all external and public functions should have @inheritdoc. | No | true | | constructorNatspec | True if the constructor should have natspec. | No | false |
