yamlfmt

I tried various beautifier of YAML files, but none of them satisfies me.

• https://pypi.org/project/yamlfmt cannot handle a file with multiple YAML objects separated by ---.
• https://github.com/devopyio/yamlfmt cannot handle multiple files.
• https://github.com/miekg/yamlfmt/blob/master/fmt.go cannot replace (inline edit) the input files.

So, I decided to write this one based on https://github.com/miekg/yamlfmt/blob/master/fmt.go.

Usage

• To beautify one or more files and write to stdout:

  yamlfmt a.yaml b.yaml c.yaml

• To beautify one or more files in the replace mode:

  yamlfmt -w a.yaml b.yaml c.yaml

• To beautify stdin and write to stdout:

  cat a.yaml | yamlfmt

• To beautify stdin and write to a file:

  cat a.yaml | yamlfmt > b.yaml
