Compare to lang-mv

Install

Best installed via bashful CLI.

bashful gist install https://gist.github.com/kyle-west/24b1a6d2b45e971cf4fc3e0b2f57e674

Usage

Assumes your components use this type of i18n structure.

lang-cp <from-dir> <from-file-prefix> <to-dir> <key-name[@<rename-key>]> [...<key-name[@<rename-key>]>]

Example

Context:

~/dev
├── project1
│   ├── locales
│   │   ├── original-component_de.json
│   │   ├── original-component_en.json
│   │   └── ...
│   └── ...
├── project2
│   ├── locales
│   └── ...
└── ...

Inside original-component_en.json:

{
  "SIGN_IN_BTN": "Sign In",
  "LOGOUT_BTN": "Sign Out",
  "GENERAL_ERROR": "An unexpected problem has occurred. Please check back later."
}

Copy the locale keys from project1 to project2 (while also renaming GENERAL_ERROR key to UNEXPECTED_ERROR):

lang-cp ~/dev/project1/locales original-component ~/dev/project2/locales \
  SIGN_IN_BTN \
  LOGOUT_BTN \
  GENERAL_ERROR@UNEXPECTED_ERROR
