xgettext-webird

Extracts translatable strings from source. Identical to xgettext(1) but for template languages.

tl;dr Get translatable strings from templates into Poedit.

Template language support

• Handlebars (using gettext-handlebars)
• Swig (using gettext-swig)
• Volt (using gettext-volt)

React's JSX and Jade are todos (PRs are much appreciated).

General workflow

In the following Handlebars example translatable content is passed to helpers (_ and ngettext):

<button>{{_ "Sign in"}}</button>

<p>{{count}} {{ngettext "country" "countries" count}}</p>

With Handlebars, this requires helpers being registered:

Handlebars.registerHelper('_', function(msgid) {
  return i18n.gettext(msgid);
});

Handlebars.registerHelper('ngettext', function(msgid, plural, count) {
  return i18n.ngettext(msgid, plural, count);
});

What this i18n object refers to is up to you. Some (client/server) options are:

• node-gettext
• Jed

xgettext-webird parses the strings above out of your templates into gettext's PO files. These PO files are then translated and compiled to binary MO files using applications like Poedit. The MO files are passed as input the i18n library (above).

Installation

$ npm install -g xgettext-webird

Usage

$ xgettext-webird [OPTION] [INPUTFILE]...

Options

• -D|--directory add directory to list for input files search.
• -o|--output write output to specified file (default: stdout).
• -L|--language specifies the language of the input files (default: determine from file extension). Use the language's full name from the template language support list above.
• --from-code encoding of input files (default: ascii).
• -k|--keyword additional keyword to be looked for (default: _,gettext,ngettext:1,2).
• --force-po write PO file even if empty (default: false).
• --no-location don't add file and line references (default: false).

In Poedit

Go to File - Preferences... in Poedit and add a new parser in the Parsers tab:

• Nunjucks
  • Language: Nunjucks
  • List of extensions...: *.nunj
  • Parser Command: xgettext-webird -L Swig --force-po -o %o %C %K %F
  • An item in keywords list: -k %k
  • An item in input files list: %f
  • Source code charset: --from-code=%c
• Volt
  • Language: Volt
  • List of extensions...: *.volt
  • Parser Command: xgettext-webird -L Volt --force-po -o %o %C %K %F
  • An item in keywords list: -k %k
  • An item in input files list: %f
  • Source code charset: --from-code=%c

Please note that in this Windows example you have to use xgettext-webird.cmd. The .cmd extension should not be there on *nix platforms.

Development

• Clone repository and run npm install.
• Run npm test to lint & test.

Note

xgettext-template initial development was founded by Dijiwan. This xgettext-webird project is a fork of xgettext-template.
