json_injector

Description

This is a tool to manipulate json files. It's main purpose is to reduce redundancy in VSCode workspaces.

It can inject missing keys from one json file into another, treat List<Map>s as Maps for the purpose of merging and apply templates.

Usage

The following invocation will update //engine.code-workspace, injecting the json data from injectors/engine.code-workspace and also applying the templates at ./injectors/engine-templates.json. List<Map>s who have the key named 'label' will be treated as Maps whose key is "label".

dart run bin/main.dart \
  --input ~/dev/engine/src/flutter/engine.code-workspace \
  --injector injectors/engine.code-workspace \
  --output ~/dev/engine/src/flutter/engine.code-workspace \
  --name-key label \
  --templates injectors/engine-templates.json
