gt@2.13.0

Overview

The t() function now automatically derives dynamic content — there is no longer any need to wrap variables in derive(). This is enabled by default and works out of the box with the GT CLI.

This is the latest step in a series of derive() improvements. First, gt-react@10.15.0 brought derive() support to the t tagged template literal. Then gt@2.12.0 extended derive() to resolve values from objects and arrays. Now, gt@2.13.0 removes the need to call derive() at all when using t().

Before & after

Previously, dynamic values in t() required an explicit derive() call:

const noun = cond ? "boy" : "girl"
const result = t("The " + derive(noun))

Now, just use the variable directly:

const noun = cond ? "boy" : "girl"
const result = t("The " + noun)

The CLI handles derivation automatically when it parses your t() calls — it detects variables with a finite set of possible string values and derives them behind the scenes.

Configuration

Auto-derive is enabled by default. To disable it, set autoDerive to false in your gt.config.json:

{
  "files": {
    "gt": {
      "parsingFlags": {
        "autoDerive": false
      }
    }
  }
}

Note: This applies only to the t() function. The t tagged template macro is unaffected — it already handles derivation through the template literal syntax introduced in gt-react@10.15.0.
