yamlctl

An experimental tool to modify YAMLs without losing (most of) comment lines.

yamlctl edit --set $.foo.bar=baz <input.yaml >output.yaml

Inline comments and some whitespaces are not preserved.

Install

go install github.com/AkihiroSuda/yamlctl/cmd/[email protected]

Usage

yamlctl editable

yamlctl editable input.yaml

Prints true if the YAML is well formatted for yamlctl edit.

Misformatted YAMLs are not safely editable, but can be edited forcibly with yamlctl edit --force.

yamlctl edit

yamlctl edit --set $.foo.bar=baz <input.yaml >output.yaml

Set -w to write back the result to input.yaml directly:

yamlctl edit -w --set $.foo.bar=baz input.yaml

Set --bak to create backup files like input.yaml.bak.0, input.yaml.bak.1, …

Set --force to edit a misformatted YAML forcibly.

yamlctl query

yamlctl query $.foo.bar input.yaml

yamlctl yaml2json

yamlctl yaml2json input.yaml

Go library (yamlutil)

See the unit tests for the usage.
