### `@babel/development-internal/report-error-message-format`
This rule is inspired by https://github.com/not-an-aardvark/eslint-plugin-eslint-plugin/blob/master/docs/rules/report-message-format.md.
Intended for use in `packages/babel-parser/src/**/*`. When enabled, this rule warns for inconsistently error messages format in arguments of `makeErrorTemplates` function calls.
Basically, it starts with an uppercase Latin letter(A~Z) and ends with a period(.) or a question(?). But it can start with `'keyword'` or `` `code` `` to include JavaScript keywords or code in error messages.
valid:
```js
makeErrorTemplates({ ThisIsAnError: "This is an error." });
makeErrorTemplates({ ThisIsAnError: "'this' is an error." });
makeErrorTemplates({ ThisIsAnError: "`this` is an error." });
makeErrorTemplates({ ThisIsAnError: "This is an error?" });
makeErrorTemplates({ ThisIsAnError: "'this' is an error?" });
makeErrorTemplates({ ThisIsAnError: "`this` is an error?" });
```
invalid:
```js
makeErrorTemplates({ ThisIsAnError: 'this is an error.' });
makeErrorTemplates({ ThisIsAnError: 'This is an error' });
makeErrorTemplates({ ThisIsAnError: 'this is an error?' });
makeErrorTemplates({ ThisIsAnError: '`this` is an error' });
makeErrorTemplates({ ThisIsAnError: "'this' is an error" });
```
Example configuration:
```js
{
rules: {
"@babel/development-internal/report-error-message-format": "error"
}
}
```
