max-length

Default severity: error

What it checks

Some strings have a hard length limit (buttons, tabs, app store fields, SMS). The limit comes from the file (XLIFF maxwidth, xcstrings, Android tools:maxLength-style metadata) or from `maxLength` globs in the config. Length is counted in characters as displayed, with tags removed and placeholders counted as written.

Example

Navigation labels limited to 12 characters with a maxLength glob in the config. Config used for both runs:

{
  "sourceLocale": "en",
  "files": [
    {
      "format": "next-intl-json",
      "path": "messages/{locale}.json"
    }
  ],
  "maxLength": {
    "nav.*": 12
  }
}

{
  "nav": {
    "settings": "Settings"
  }
}

{
  "nav": {
    "settings": "Paramètres du compte"
  }
}

{
  "nav": {
    "settings": "Settings"
  }
}

{
  "nav": {
    "settings": "Paramètres"
  }
}

Change its severity

{
  "checks": {
    "max-length": "warning"
  }
}

Use "off" to disable it. To hide one finding, add "suppress": ["max-length:nav.settings"]; a suppress rule that stops matching is reported so it can be removed.
