Build

mvn -P uberjar package

Requires 'maven' build automation tool.

Install maven on OS X using homebrew: brew install maven

Usage

./bin/merge-yml.sh file1.yml file2.yml ... > merged-result.yml

Files are merged in order, such that files listed later will override files listed earlier.

The merged result is written to stdout. Logs (for info & errors) are written to stderr.

Within the YML files to be merged, you may include references to system environment variables using mustache-style syntax, for example:

callbackUrl: http://www.{{DEPLOY_HOST_NAME}}.example.com:8102/my_callback

Then make sure you've exported the DEPLOY_HOST_NAME environment variable to whatever place you invoke merge-yml from.
