CONFLATE

Library providing routines to merge and validate JSON, YAML, TOML files and/or structs (godoc)

Description

Conflate is a library that provides the following features :

• merge data from multiple formats (JSON/YAML/TOML/go structs) and multiple locations (filesystem paths and urls)
• validate the merged data against a JSON schema
• apply any default values defined in a JSON schema to the merged data
• expand environment variables inside the data
• marshal merged data to multiple formats (JSON/YAML/TOML/go structs)

Data files can include other files using the includes array, meaning that they will be merged (i.e. in JSON this is simply a string array at the top-level). The includes array can support multiple path types (see below), including relative paths to local or remote files. Values present in the containing file override those from any file in the includes array, and values from any file in the includes array override those from files before it in the includes array :

{
  "includes": [
    "./myfile.json",
    "/etc/myfolder/myfile.yaml",
    "file://etc/myfolder/myfile.toml",
    "http://mydomain/myfile"
  ],
  "mydata": 123
}

Usage
