With new version @messageformat/core (they change name) not working about gettext-to-messageformat

[eemeli]

Could you provide a full minimal example of what triggers this error? It's really rather hard to diagnose with just that.

const FS = require('fs');
const MessageFormat = require('@messageformat/core');

// i18n START
const Lang: string = 'en'; // for demo hardcoded
const EscStr = '&-p-&';
let i18n: any = {};
if (Lang) {
  const poFile = `i18n/${Lang}.po`;
  try {
    let po = FS.readFileSync(poFile, 'utf8');

    const { parsePo } = require('gettext-to-messageformat');
    const { headers, pluralFunction, translations } = parsePo(po.replace(/%(?![s|n|1])/g, EscStr));
    const mf = new MessageFormat('en', { [headers.language]: pluralFunction });
    i18n = mf.compile(translations); 
  } catch (e: any) {
    console.error(e);
  }
}
// i18n END

@Eutrepe Could you also share at least a partial .po file that triggers this error?

[Eutrepe]

Yes, of course

msgid ""
msgstr ""
"Content-Type: text/plain; charset=UTF-8\n"
"Content-Transfer-Encoding: 8bit\n"
"Plural-Forms: nplurals=3; plural=(n==1 ? 0 : n%10>=2 && n%10<=4 && (n%100<10 || n%100>=20) ? 1 : 2);\n"
"Project-Id-Version: \n"
"POT-Creation-Date: \n"
"PO-Revision-Date: \n"
"Language-Team: \n"
"MIME-Version: 1.0\n"
"X-Generator: Poedit 2.4.2\n"
"Report-Msgid-Bugs-To: \n"
"Last-Translator: \n"
"Language: en\n"

msgid "test"
msgstr "Test text"

Ah, you're calling the wrong function, mf.compile(...) rather than compileModule(mf, ...). This API change was a part of the v3 release, see here for update instructions: https://github.com/messageformat/messageformat/releases/tag/messageformat%403.0.0-beta.1

Thank you, I checked today, sorry for the inconvenience. Everything is fine with your plugin
