আমি টুইগের মধ্যে '#মার্কআপ' লিঙ্কটি পরিবর্তন করার কোনও উপায় খুঁজে পাইনি, তবে এটি রেন্ডার পর্যায়ে পরিবর্তন করার উপায় রয়েছে।
আমি এই ছোট্ট মডিউলটি তৈরি করেছি যা লিঙ্ক কার্যকারিতা প্রসারিত করে এবং রেন্ডার লিঙ্কটিতে কিছু স্টাফ ইনজেকশনে সক্ষম করে তোলে। সুতরাং কিছু কোড করা যাক, আমি মন্তব্যগুলিতে ব্যাখ্যা করব ...

গুরুত্বপূর্ণ:
এটি আপনার সমস্ত লিঙ্ক ক্ষেত্রের জন্য কাজ করবে , নিশ্চিতভাবেই, আপনি যদি এটির প্রদর্শনের ব্যবস্থাপনায় এর বিন্যাস পরিবর্তন করেন (আপনার নোডের ধরণটি সম্পাদনা করছেন)।
আমি আশা করি এটি কার্যকর হতে পারে।
@Artfulrobot- কে অনুরোধ: আপনি কি এই মডিউলটি পরীক্ষা করতে পারেন? আমি মনে করি যে অনুবাদ সমস্যার সমাধান এইভাবে করা যেতে পারে।
