          cspell:fullstack/dict/fullstack.txt
          cspell:java/src/java.txt
          cspell:filetypes/filetypes.txt
          cspell:java/src/java-terms.txt

To stop checking additional dictionaries, add (in .github/workflows/spell.yml):

check_extra_dictionaries: ''

• binary file (or some other file you wouldn't want to check at all).

  Please add a file path to the excludes.txt file matching the containing file.

  File paths are Perl 5 Regular Expressions - you can test yours before committing to verify it will match your files.

  ^ refers to the file's path from the root of the repository, so ^README\.md$ would exclude README.md (on whichever branch you're using).

• well-formed pattern.

  If you can write a pattern that would match it,
  try adding it to the patterns.txt file.

  Patterns are Perl 5 Regular Expressions - you can test yours before committing to verify it will match your lines.

  Note that patterns can't match multiline strings.
