Unfortunately I think we missed that what repology calls 'dotenv' points to https://ports.macports.org/port/dotenv which points to https://github.com/gyf304/dotenv , not https://github.com/Ayush272002/dotenv

@Ayush272002 Would you find naming the port ayush272002-dotenv acceptable? Note that this is only about the name of the port, there is no ask to change header/library/etc. names.

Would cpp-dotenv be acceptable instead? It clearly indicates it's a C++ library and is shorter than ayush272002-dotenv.

Common prefixes and suffixes used by C++ and open source projects are not valid disambiguators, some examples include but are not limited to:

• cpp,
• free,
• lib,
• open,
• numbers

Even without this maintainer guideline https://github.com/gyf304/dotenv is also written in C so it wouldn't be a very good disambiguator

That makes sense, I understand the guideline. I'll go with ayush272002-dotenv then. I have updated the PR accordingly.
