American Fuzzy Lop VS copilot.vim

There's some efforts to guide test generation for property based testing to make the instruction pointer explore as large a space as possible.

This effort is more mature in the fuzzing community. See eg American Fuzzy Lop https://github.com/google/AFL

What you're describing, just generating random input to test a program, is sometimes called "blind fuzzing" but the state-of-the-art is far beyond that. Maybe try reading through the documentation of e.g. https://github.com/google/AFL to see what a fuzzer does and why just producing random input isn't even scratching the surface.

for general riscv I used to use this https://github.com/google/AFL I dont know if it supports x64 tho.

Ex ( AFL, WinAFL, HonggFuzz, LibFuzzer, Jazzer )

I wrote this little fuzz test target in order to fuzz it with afl (under ASan and UBSan):

afl, which is trivial to apply to this program:

I made my own version of a TCL interpreter (well, a very TCL like langauge) derived from "picol" available at https://github.com/howerj/pickle. There are many different re-implementations and derivatives of this interpreter but they all seem very "crashy", this one has been significantly hardened by using a fuzzer on it which ran for months called American Fuzzy Lop https://lcamtuf.coredump.cx/afl/ . It is also more suitable for embedded use whilst still not having arbitrary restrictions like many other implementations.

On Linux afl is a very powerful bug-finding tool, and it's a great companion when doing code review. Composes well with ASan and UBSan.

I use copilot in neovim[1]. It was remarkably simple to get installed. Highly recommend

[1]: https://github.com/github/copilot.vim

I use Plug 'tpope/vim-markdown' and markdown fenced codeblocks fairly extensively, and recently installed Copilot.vim.

Anyways. Yes, neovim has AI integration like copilot ( https://github.com/github/copilot.vim ) and chatgpt ( https://github.com/jackMort/ChatGPT.nvim )

I do think VSCode is a great tool and I recommend it frequently to people, but I still want to set the record straight here. Yes, vim is obviously limited in the sense that as a CLI app it doesn't draw it's own PDF or HTML windows, that's fair. But it can remote control your favorite PDF viewer or browser for roughly the same functionality. I'm currently writing my thesis using vimtex and it's quite smooth. And all the other stuff you mention is implemented quite competently by various plugins like vim-fugitive, coc.nvim, vimspector and copilot.vim.
