i18n task

[krzysztof-kabala]

php cli/cli.php vegas:i18n generate

Task will generate "{langDir}/{lang}/LC_MESSAGES/messages.po" file for each $langs language item.
If final file exists, overwrite it by adding new translations, but without modify translated items.

Task requires xgettext installed, node.js and xgettext-template (as global), see:

• https://www.gnu.org/software/gettext/
• https://www.npmjs.com/package/xgettext-template

Supported file types:

• PHP
• VOLT

HOWTO:

1. Extend I18nTask into Your app
2. Overwrite $directories, $langDir and $langs (+ other params if needed)
3. Overwrite addToFinalPo(PO_FILE_PATH); to add database translation into final.PO
   You may use generatePoContent method to generate PO content
   from array of string or array [msgid,?msgstr,?comment] where "?" keys are optional (see sample below)
4. Use "POEdit" to manage translations

Sample of addToFinalPo using:

protected function addToFinalPo($tmpPo)
{
$newPo = $this->getTmpFile();

file_put_contents($newPo, $this->generatePoContent([
'message1', 'other message', 'dynamic %s message'
]));

$this->addPo($tmpPo, $newPo);
}

If You are using non-utf8 standard charset, consider adding own header into PO files.
