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.
-
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
