invert-text

A simple tool to generate inverted/upside-down/australiaized/upended/upturned text. Generates inverted text using Unicode characters.

A better mechanism for testing Localization (L10N) compared to translations of a different language, for two reasons:

• It's easy to quickly generate a JSON with inverted texts. (You don't need a paid translation API).
• When testing l10n on the interface, it's easy to identify if the right word/phrase is being translated (just need to rotate your head enough 🙃 ).

Installation

• Install Node.js and npm
• Install the invert-text CLI globally using npm i -g invert-text
  • Or, run it directly using npx

Usage

Invert a JSON file

To invert all leaf-level text phrases in a given JSON file, use the invert-text command as below:

foo@bar:~$ invert-text -i path/to/input.json -o path/to/output.json

✅ Generated the inverted output file at "path/to/output.json"

Invert phrase(s)

To invert single/multiple text phrases, use the invert-text command as below:

foo@bar:~$ invert-text -p this that "and something else"

⚠️  Limitations

• Works mainly with AlphaNumeric characters. Most other characters are returned without any inversion.
• Depending on the font used, some of the inverted characters can look odd/incorrect when inverted.
