Kawa is a small command-line tool to manage some key-value store in a single file. It manages files containing key-value pairs like the following. These files are meant to be human-readable.

hostname = localhost
port = 5432
username = myuser
password = secret
database = mydb

There are three commands supported by the executable: get, set and replace which, respectively, gets the value assigned to a key from a store, sets a new value to a key in a store and replaces all occurences of keys by their values in a file.

This can be used to generate a file from a template and some secrets contained in such a store. For instance, a provisioning tool could create a file config.template.yml for some application containing its configuration with lines like username: USERNAME and the variables would be stored in secrets.kawa. Then, before launching the application, a systemd service could run kawa replace secrets.kawa -i config.template.yml -o config.yml.
