Newline Linter

3.206 Line
A sequence of zero or more non-<newline> characters plus a terminating <newline> character.

Overview

No, newline at end of file.

Lint tracked non-binary files that do not end in a newline, either locally with a Git subcommand or in CI with GitHub Actions.

Git Subcommand

Install git-no-newlines in your path and run

git no-newlines

in a Git repository to list non-binary files that do not terminate in a newline. Setting EXCLUDE_PATTERN to an extended-grep-compatible pattern will exclude matching files.

GitHub Action

Inputs

• exclusion_pattern
  • Optional extended-grep-compatible pattern of filenames to exclude.

Example

- name: Lint newlines
  uses: fionn/newline-linter@master
  with:
    exclusion_pattern: intentionally_unterminated_file
