This pull request seeks to introduce a new ESLint rule to help protect against invalid use of sprintf.

Specifically, it enforces:

  • That it's called with a format string
  • That it's called with 1 or more placeholder substitute values
  • That the format string contains at least one placeholder
  • That each format string option (if using _n or _nx) contain an identical number of placeholders (a common error is forming a string like sprintf( _n( 'One cat', '%d cats', num ) ))

It does not (yet) enforce:

  • That the placeholder formats are valid
  • That the number of placeholders matches the number of arguments passed (this becomes tricky, especially with named placeholders and re-use of positional arguments e.g. sprintf( '%1$s %1$s', '1' ) is valid)

Testing instructions:

Verify that the description for the Embed block shows as expected:

Add a block that displays content pulled from other sites, like Twitter, Instagram or YouTube.

Ensure tests pass:

npm test
