CLI tool to convert HOCON into valid JSON or YAML written in Rust.

Overview

{hocon:vert}

CLI Tool to convert HOCON into valid JSON or YAML.

Under normal circumstances this is mostly not needed because hocon configs are parsed within the application – case closed. But for example in conjunction with Kubernetes where .conf files can reside in ConfigMaps there was that need to extract information on command line from time to time. And what would be more comfortable than to use jq for this.

Usage

hoconvert [input] [--yaml]

Either provide the hocon as first argument:

hoconvert "foo = bar"

or provide it from stdin,

echo "foo = bar" | hoconvert

which leads to the following output:

{
  "foo": "bar"
}

Here is an example of a real-life Kubernetes problem as stated above:

kubectl get cm <any ConfigMap> -o jsonpath='{.data.myHocon}' | jq -r | hoconvert | jq '.doWhatEverYouWant'
