Scanner not adding language and utf-8 encoding headers to .po file

[ideiasfrescas]

Hello

I have the following po file contents, resulting from a scan for php files:

msgid ""
msgstr ""
"X-Domain: messages\n"

#: /var/www/html/the_site/_teste.php:41
msgid "dah"
msgstr ""

I have the following code to scan for files:

/*considering the following folder structure:
vendor
    /my_plugins
        /module1
        /module2
*/
$LOCALES = ["en" => "en_GB","pt" => "pt_PT"];

$folders= new DirectoryIterator("vendor/my_plugins");

foreach($folders as $folder) {

    $path = $folder->getFilename();
    
    $DOMAIN = "module1"; //in my actual code, domain takes several different names depending on the folder the iterator is working on
    
    $destination_folder = $folder->getPathname()."/locale/"; //will save in vendor/my_plugins/module1/locale
    
    foreach($LOCALES as $code => $locale) {
    
            if (!file_exists($destination_folder) || !file_exists($destination_folder.$locale)) {
                    //folder creation
                    mkdir($destination_folder.$locale,0777,true);
                    
            }
    }
    
     foreach(LOCALES as $codigo => $locale) {
     
         $phpScanner = new PhpScanner(
             Translations::create($DOMAIN)
          );
          $phpScanner->setDefaultDomain($DOMAIN);
          //resulting PO file matches $DOMAIN
          
          $phpScanner->scanFile("some_file.php");  //this also works
          
          //done scanning, let's go to generate files
          $FILE = $destination_folder.$locale."/".$DOMAIN.".po";
          
          $po_generator = new PoGenerator();
          $mo_generator = new MoGenerator();
          
          foreach ($phpScanner->getTranslations() as $domain => $translations) {
                  //line below raises: Fatal error: Uncaught Error: Call to undefined method Gettext\Translations::setHeader() in
                  $translations->setHeader("Content-Type", "text/plain; charset=UTF-8");

                  //seems to work, but po file does not seem to have the "language" header
                  $translations->setLanguage($locale); //should be pt_PT or pt_PT.utf8 ( the latter is installed in my system )

                  $po_generator->generateFile($translations, $FILE);
          }
     }
     

What is the proper way to set headers in the file, using PHP-Scanner? Should I load it again with Loader and the set the headers it, and finally generate the mo file?

[oscarotero]

The headers of a Translations instance are stored in a Headers container:

$headers = $translations->getHeaders();
$headers->set("Content-Type", "text/plain; charset=UTF-8");
$headers->setLanguage($locale);

The solution you provided no longer gives me the fatal error, but still there are no headers ( except for the X-Domain ) present in the generated .po file. I will manually patch the po file with PHP for the time being.

[Edit]
After I purged the files, I ran the script and it works. No need to patch it.
Thank you.
