I suggest including a built-in dictionary.

Hello, my understanding is that updating is definitely better, but a dictionary file named path.txt needs to be kept in the project, for example: feroxbuster -u google.com

It will scan path.txt by default.

I can add updates directly if needed.

It's cumbersome to specify the dictionary path every time.

And it's even more troublesome to find a new dictionary every time it runs on a different machine. What do you think?

I see that this project is a binary file, so it's not actually necessary for you to include the default dictionary in the tool itself. Rather, if no dictionary path is specified, it will scan for "xxx.TXT" files in the same directory as the binary file by default.
