Check for Newline at File End

Fend recursively scans all files in a directory and reports those that don't end in a new line character (\n).

It is a POSIX Standard that you should, arguably adhere to.

This StackOverflow post captures the why? better than I could:

https://stackoverflow.com/questions/729692/why-should-text-files-end-with-a-newline

It will mean no more GitHub warnings for 'No newline at EOF' on Pull Request.

By enforcing this check using the GitHub Action you can automate a basic Standard in your project.

Consistent is clean. Clean is good. Don't overthink it. 👌

See .github/workflows/fend.yaml as the Action is run on this repository!

See Configuration for additonal options.

jobs:
  fend:
    name: Fend
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@master
    - uses: njgibbon/fend@main

That's all! 💫

Running Fend on some well known repositories and recording the results!

docs/research/readme.md.

• Fend always ignores all '.git' directories and non-regular files like symlinks.
• To skip anything else see Configuration. You will want to configure the tool to skip any binary file types found in your repository - like any images for instance.

go get -u github.com/njgibbon/fend/cmd/fend
# ensure binary can be found in $PATH e.g
# mv ~/go/bin/fend ~/my/bin
cd <dir-to-scan>

The scanner component can easily be used as a package. See cmd/fend/main.go and pkg/scanner/scanner_test.go for usage examples.

Place a file called .fend.yaml in the working directory to configure your scan. See .fend.yaml for the configuration used for the fend GitHub Action on this repository.

skip:
  file: 
    - skip_file.txt
  file_all: 
    - skip_file_all.txt
  dir:
    - skip-dir
  dir_all:
    - skip-dir-all
  extension: 
    - .skip
    - .ignore

• You can skip specific files or directories by providing the full path.
• You can skip all instances of a file or directory.
• You can skip all files with certain extensions. The Failure Extensions Feature can be used to help you configure a good skip list. See docs/research/checkov/readme.md for an example of how you can quickly configure the right skips.

Project used as a vehicle to help learn some of the basics of tool development using Go and also to explore GitHub Actions from a development point of view as I have had a really positive experience with GitHub Actions from the user perspective.
