CLI for extracting Gettext messages from JavaScript, TypeScript, JSX and HTML

This CLI is essentially a convenience wrapper around gettext-extractor, all the processing is done by this library.

Installation

Usage

Usage: gettext-extract [options]

Options:
  -c, --config  Config file [default: .gettext.json]
  -o, --output  Output file [default: template.pot]
  -h, --help    Show this help

Configuration

Configuration for message extraction can be provided using a .gettext.json file, a custom JSON file using the --config CLI option or by adding a gettext object in your package.json.

Here is an example configuration (remove comments for valid JSON):

{
  "js": {
    "parsers": [
      {
        "expression": "gettext",
        "arguments": {
          "text": 0
        }
      },
      {
        "expression": "ngettext",
        "arguments": {
          "text": 0,
          "textPlural": 1
        }
      },
      {
        "expression": "pgettext",
        "arguments": {
          "context": 0,
          "text": 1
        }
      }
    ],
    "glob": {
      // [node-glob pattern(https://github.com/isaacs/node-glob#glob-primer) to match your JS files
      "pattern": "src/**/*.ts",
      // Add any [node-glob options](https://github.com/isaacs/node-glob#options) here
      "options": {
        "ignore": "src/**/*.spec.ts"
      }
    }
  },
  "html": {
    "parsers": [
      {
        // Extract message from content of the HTML element with the specified CSS selector
        "element": "[translate]",
        "attributes": {
          "textPlural": "translate-plural",
          "context": "translate-context"
        }
      },
      {
        // Extract message from attribute of the HTML element
        "attribute": "translate-text",
        "attributes": {
          "textPlural": "translate-plural",
          "context": "translate-context"
        }
      }
    ],
    "glob": {
      "pattern": "src/**/*.html"
    }
  },
  //
  "headers": {
    "Language": ""
  },
  "output": "translations/template.pot"
}

At least one valid parser (JS or HTML) with glob pattern must be present, everything else is optional.

You can fin additional information concerning the JavaScript / TypeScript / JSX or HTML parsers on the gettext-extractor wiki.
