Exit Codes

FSH Lint uses specific exit codes to indicate different outcomes.

Exit Code Reference

0 - Success

No errors found. May contain warnings or hints.

maki lint file.fsh
echo $?  # 0

1 - Lint Errors

Lint errors were found in the files.

maki lint invalid.fsh
echo $?  # 1

2 - Invalid Configuration

Configuration file is invalid or malformed.

maki lint --config invalid.json *.fsh
echo $?  # 2

3 - File Not Found

Specified files or directories not found.

maki lint nonexistent.fsh
echo $?  # 3

4 - Invalid Arguments

Invalid command-line arguments provided.

maki lint --unknown-flag *.fsh
echo $?  # 4

5 - Internal Error

An internal error occurred.

# Should not happen in normal use
echo $?  # 5

CI/CD Integration

Use exit codes in CI/CD pipelines:

GitHub Actions

- name: Lint FSH files
  run: |
    maki lint **/*.fsh
    if [ $? -eq 1 ]; then
      echo "Lint errors found"
      exit 1
    fi

GitLab CI

lint:
  script:
    - maki lint **/*.fsh
  allow_failure: false

Jenkins

stage('Lint') {
  steps {
    sh '''
      maki lint **/*.fsh
      EXIT_CODE=$?
      if [ $EXIT_CODE -ne 0 ]; then
        echo "Linting failed with code $EXIT_CODE"
        exit $EXIT_CODE
      fi
    '''
  }
}

Warning-Only Mode

Treat warnings as errors for stricter CI:

maki lint --severity warn **/*.fsh

This will exit with code 1 if any warnings are found.

Ignoring Specific Exit Codes

Continue on warnings but fail on errors:

maki lint **/*.fsh || [ $? -eq 0 -o $? -eq 1 ] && echo "OK"
