catj

Displays JSON files in a flat format.

Input:

{
  "mappings": {
    "templates": [
      {
        "fields": {
          "mapping": {
            "norms": false,
            "type": "text",
            "fields": {
              "keyword": {
                "ignore_above": 256,
                "type": "keyword"
              }
            }
          }
        }
      }
    ]
  }
}

Output:

.mappings.templates[0].fields.mapping.norms = false
.mappings.templates[0].fields.mapping.type = "text"
.mappings.templates[0].fields.mapping.fields.keyword.ignore_above = 256
.mappings.templates[0].fields.mapping.fields.keyword.type = "keyword"

Why?

• It makes it easier to understand the structure of JSON files.
• The output is valid JavaScript which can be used directly in code.
• It's very helpful when writing queries for tools like jq.

Install
