मैंने जो कुछ भी एकत्र किया है उससे आप विवरण के बीच अंतर देखने के लिए पाठ में अंतर को उजागर करने का एक तरीका देख रहे हैं। वहां से, क्या मैं सुझाव दे सकता हूं कि आप diff फ़ंक्शन को केवल b_discription . तक सीमित करें क्योंकि अन्य विशेषताएँ आपकी ज़रूरत के दायरे में नहीं आती हैं। क्या आप उम्मीद करते हैं business_logo , business_name या mod_date परिवर्तित करने की? भले ही, निम्न फ़ंक्शन को आपके ऑब्जेक्ट में सभी विशेषताओं पर चलाया जा सकता है यदि उन्हें एक स्ट्रिंग में परिवर्तित किया जा सकता है।
simplediff एक उत्कृष्ट स्क्रिप्ट है जो दो स्ट्रिंग्स के बीच अंतर ढूंढती है, जिनमें शामिल हैं:
- ए में मौजूद है और बी में नहीं है (हटाना)
- बी में मौजूद है और ए (सम्मिलन) में नहीं है
