Summary

When running ./scripts/generate_baseline.py -l error output contains...

/Users/notme/macos_security/./scripts/generate_baseline.py:135: SyntaxWarning: invalid escape sequence '\|'
  all_rules.append(MacSecurityRule(rule_yaml['title'].replace('|', '\|'),
/Users/notme/macos_security/./scripts/generate_baseline.py:136: SyntaxWarning: invalid escape sequence '\|'
  rule_yaml['id'].replace('|', '\|'),
/Users/notme/macos_security/./scripts/generate_baseline.py:137: SyntaxWarning: invalid escape sequence '\|'
  rule_yaml['severity'].replace('|', '\|'),
/Users/notme/macos_security/./scripts/generate_baseline.py:138: SyntaxWarning: invalid escape sequence '\|'
  rule_yaml['discussion'].replace('|', '\|'),
/Users/notme/macos_security/./scripts/generate_baseline.py:139: SyntaxWarning: invalid escape sequence '\|'
  rule_yaml['check'].replace('|', '\|'),
/Users/notme/macos_security/./scripts/generate_baseline.py:140: SyntaxWarning: invalid escape sequence '\|'
  rule_yaml['fix'].replace('|', '\|'),

Afterward the expected list of tags shows.

Steps to reproduce

Stated above. Most likely due to an issue in the collect_rules function.

Operating System version

Sonoma 14.3 (23D56)

Intel or Apple Silicon

Apple silicon

What is the expected correct behavior?

No associated syntax errors are included in output. Rules are read correctly.

Possible fixes

Output indicates the problem is around here with how text is being parsed.
