Gettext linting rules for ESLint.

We're using this rule to lint against misuse of the jed gettext integration and the django JS catalog; so we're confident it should work against any gettext integration.

Installation

  1. Install ESLint.
  2. Install eslint-plugin-gettext plugin.
npm install eslint --save-dev
npm install eslint-plugin-gettext --save-dev

Configuration

  1. Load plugin.
  2. Enable rules.
{
  "plugins": ["gettext"],
  "rules": {
    "gettext/no-variable-string": "error",
    "gettext/required-positional-markers-for-multiple-variables": "error"
  }
}

Rules

gettext/no-variable-string

Disallow non literal strings inside common gettext functions. This is a very common mistake that disallow translation system from statically collecting the translatable strings.

// Disallows any non string literals in string reserved fields:
gettext(variable)
gettext(123)
ngettext(varA, varB, 5)
pgettext(varA, varB)
npgettext(varA, varB, varC, 5)

// Allows:
gettext('hello')
ngettext('cat', '%d cats', 5)
pgettext('homepage', 'hello')
npgettext('homepage', 'cat', '%d cats', 5)
i18n.gettext('hello') // any object can expose the gettext API
this.gettext('hello')

gettext/required-positional-markers-for-multiple-variables

Require that all strings containing multiple variables also includes positional marker. This allows translator to reorder variables, and prevents sprintf() errors if someone change the order of %s and %d.

// Disallows:
gettext('There is %d more event in the %s.')
gettext('There is %d more event in the %1$s.')

// Allows:
gettext('There is %d more event in the game.')
ngettext('cat %1$s $2$s', '%1$d cats %2$d dogs', count)
