or we could move generating just grammar.js into its own function

Potential solution

The user's issue suggests that there is uncertainty about whether to keep the automatic generation of grammar.js or to move it to a manual process. The user also proposes the possibility of moving the generation of grammar.js into its own function. The decision should be based on the project's goals, ease of use for the end-user, and maintainability of the codebase.

Given the context, creating a dedicated function to generate grammar.js seems to be a balanced approach. It maintains the convenience of having a template while also providing flexibility for users who may want to customize or extend the generation process. This approach would also allow for easier testing and documentation updates.

How to implement

1. Implement a new function in src/generate-grammar.js:
   • Create a function named generateGrammarTemplate that generates grammar.js using a default template.
   • Ensure that the function is exportable so that it can be called externally.

// src/generate-grammar.js

function generateGrammarTemplate() {
  const defaultTemplate = `// Default grammar template content`;
  // Logic to write the defaultTemplate to a grammar.js file
}

module.exports = { generateGrammarTemplate };

2. Update README.md with instructions for using the new function:
   • Include a section that explains the purpose of grammar.js.
   • Document the generateGrammarTemplate function and provide a usage example.

## Generating `grammar.js`

### Using the Generation Function

`grammar.js` can be generated using the `generateGrammarTemplate` function provided by the library.

#### How to Use the Generation Function

To generate `grammar.js`, follow these steps:

1. Import the `generateGrammarTemplate` function from the library.
2. Call the function to create the `grammar.js` file.

Example:

```javascript
const { generateGrammarTemplate } = require('path-to-generate-grammar');

generateGrammarTemplate();

3. **Write tests in `tests/generate-grammar-tests.js`:**
   - Create tests that check if `generateGrammarTemplate` function generates `grammar.js` correctly.
   - Test for correct file creation and content matching the default template.

```javascript
// tests/generate-grammar-tests.js

const { generateGrammarTemplate } = require('../src/generate-grammar');
const fs = require('fs');
const path = require('path');
const assert = require('assert');

describe('generateGrammarTemplate', () => {
  it('should generate grammar.js with the default template', () => {
    generateGrammarTemplate();
    const grammarContent = fs.readFileSync(path.join(__dirname, 'grammar.js'), 'utf8');
    const expectedContent = `// Default grammar template content`;
    assert.strictEqual(grammarContent, expectedContent);
  });
});

By implementing these changes, the project will provide a clear and maintainable way to generate grammar.js, while also offering the flexibility for users to create or modify it manually if they choose to do so.

Changes on tests/generate-grammar-tests.js

Since the tests/generate-grammar-tests.js file is new and contains no actual tests or code, there is no immediate action required for this file in response to the user's issue. However, once changes are made to the src/generate-grammar.js file based on the decision taken (either moving grammar.js generation into its own function or removing the generation code), tests will need to be written or updated in this file to reflect those changes.

Here's a practical proposal for when the time comes to implement tests:

1. If a new function is created for generating grammar.js:

   • Write tests that ensure the new function correctly generates grammar.js using the default template.
   • Test different scenarios, including edge cases, to ensure robustness.
   • Verify that the generated grammar.js file meets the expected format and content standards.

2. If the generation code is removed:

   • Since there would be no generation code to test, this file would remain empty until there are other related features or functions that require testing.
   • If instructions are provided for users to create grammar.js manually, consider writing tests that validate user-created grammar.js files against the expected format and content standards, if such validation becomes part of the tool's functionality.

For now, you can leave this file as is, and once the decision is made and implemented in src/generate-grammar.js, you can proceed to write the appropriate tests.

Changes on README.md

Since the README.md file is new and contains no information, we will need to create documentation that reflects the changes made to the generation process of grammar.js. Depending on the decision made regarding the generation of grammar.js, the documentation will vary.

If the decision is to move the generation of grammar.js into its own function, the README.md should include:

1. An explanation of the purpose of grammar.js and why it is important.
2. A clear description of the new function that generates grammar.js, including its name and any parameters it takes.
3. Step-by-step instructions on how to use the new function to generate grammar.js.
4. Any additional options or configurations that can be applied when generating grammar.js.

If the decision is to remove the automatic generation of grammar.js and require users to create it manually, the README.md should include:

1. An explanation of the change and the reasons behind it.
2. Instructions on how to manually create grammar.js, including the default template that users can start with.
3. Best practices for creating and maintaining grammar.js.
4. Any necessary information about the structure and content that grammar.js should contain.

In either case, the README.md should be written in clear, concise language that is accessible to users with varying levels of technical expertise. It should also be formatted in a way that is easy to read, with proper use of headings, code blocks, and lists where appropriate.

Here is a template for the README.md that can be adapted based on the final decision:

# Project Name

Brief description of the project and its purpose.

## Generating `grammar.js`

### Option 1: Using the Generation Function (if applicable)

Explain that `grammar.js` can be generated using a provided function.

- Option 2: Description of option 2.

### Option 2: Manual Creation (if applicable)

Explain that users need to manually create `grammar.js` and provide the reasons for this change.

#### How to Manually Create `grammar.js`

1. Step 1: Description of step 1.
2. Step 2: Description of step 2.

  <summary>Changes on src/generate-grammar.js</summary>
  
  Since the `src/generate-grammar.js` file is new and currently empty, there is no existing code to refactor or remove. The task at hand is to decide on the best course of action regarding the generation of `grammar.js`.

Based on the user's issue, there are a few options:

1. **Create a function to generate `grammar.js`:** If the decision is to provide a function for generating `grammar.js`, then the new function should be implemented in this file. The function would use a default template to create the `grammar.js` file, and it should be designed to be easily called by the user when needed.

2. **Remove the generation code:** If the decision is to not include a generation function and instead have users create `grammar.js` manually, then this file would remain empty or could be removed from the project altogether. In this case, the documentation would need to be updated to guide users on how to create `grammar.js` themselves.

3. **Update the generation process to use the default template correctly:** If the generation process is to be kept but needs to be updated to use the default template correctly, then the code for this process should be implemented in this file. This would involve writing the logic to correctly apply the default template when generating `grammar.js`.

Given that the file is currently empty, the practical proposal would be to:

- Discuss with the team or stakeholders to decide on the preferred approach.
- If a generation function is preferred, implement the function in this file.
- If manual creation is preferred, provide instructions in the documentation and consider removing this file.
- If updating the generation process is preferred, write the necessary code in this file to use the default template correctly.

Once the decision is made and the appropriate action is taken, the README.md and tests in `tests/generate-grammar-tests.js` should be updated accordingly to reflect the changes made to the generation process of `grammar.js`.
