NAME

kas-diff - kas diff plugin

SYNOPSIS

kas diff [-h] [--skip STEP] [--force-checkout] [--update]

         [--content-only]


         config1 config2


DESCRIPTION

Compare two kas configurations.

This plugin implements the kas diff command.

This plugin compares two KAS configurations and outputs the differences. The diff includes both content differences in the configuration files and repository differences if commit IDs or tags have changed.

Additionally, you can use the --format json option to output the diff in JSON format.

Note:

The text output of the plugin should not considered to be stable. If stable output is needed, use a machine readable format like json.
