eslint-plugin-max-tokens is an ESLint plugin that enforces a maximum token length for files in your project. It helps ensure that your source code files do not exceed a specified token limit, which can be useful for optimizing code size and adhering to certain constraints.

You can install eslint-plugin-max-tokens using npm:

npm install eslint-plugin-max-tokens --save-dev

To use the plugin, you need to add it to your ESLint configuration file (e.g., .eslintrc.json) and enable the max-tokens/max-tokens rule:

{
  "plugins": ["max-tokens"],
  "rules": {
    "max-tokens/max-tokens": ["warn", { "maxTokenLength": 8192 }]
  }
}

In the above example, the max-tokens/max-tokens rule is set to "warn", and the maxTokenLength option is set to 8192. You can adjust the maxTokenLength value according to your project's requirements.

The max-tokens/max-tokens rule enforces a maximum token length for each file in your project. It uses the gpt-tokenizer library to tokenize the source code and counts the number of tokens.

If the token length of a file exceeds the specified maxTokenLength, the rule will report a warning or error (depending on the rule configuration).

The max-tokens/max-tokens rule accepts an optional options object with the following property:

• maxTokenLength (number): The maximum allowed token length for a file. Default value is 4096.

{
  "plugins": ["max-tokens"],
  "rules": {
    "max-tokens/max-tokens": ["error", { "maxTokenLength": 10000 }]
  }
}

In this example, the max-tokens/max-tokens rule is set to "error", and the maxTokenLength option is set to 10000. Files exceeding 10,000 tokens will trigger an error.
