cfn-lint-to-codeframe

1.0.6 verified Fri May 01 auth: no javascript

A CLI tool that converts the parseable output from cfn-lint (the Python AWS CloudFormation linter) into a human-friendly, code-frame style error display. Current version 1.0.6 takes stdin from cfn-lint's --format parseable output and reformats it with line-by-line context. Regular patch releases fix edge cases like multi-line messages and JSON parse errors. Simpler than using cfn-lint's own formatter, especially for CI pipelines.
