luv VS babelfish.nvim

Hi, I had this issue and I solved it by building https://github.com/luvit/luv myself.

To answer the OP's question, you could tackle luv and libuv ecosystem, as a way to connect Lua to real-world systems (files, sockets, servers...). That's one way to put Lua skills to use, there are other great answers in the thread. Another recommendation is to go through Programming in Lua book, especially the later chapters where you learn how Lua talks to the host application.

Alternatively you can get into the weeds and play around with the in built vim.loop (which is really just luv, specifically spawn to run commands on the OS and handle stdout processing via stream.

Unfortunately I doubt they are able to use netrw, it interfaces with user facing buffers too much. Telescope uses plenary which uses lua's luv implementation (bound to vim.loop). Fzf-lua uses an external binary called fzf

Lua is still actively used so there is a great number of libraries that came out in last 9 years. A decent example is the luv library that is packed with great functionality. On the whole I'm quite satisfied with the ecosystem, but it all depends on the domain.

You should be able to find plenty of examples of asynchronous code at https://github.com/luvit/luv and translate it.

The first thing I would recommend is read the official documentation. Both libuv and luvit (or more specifically luv)

I spent some time converting the luv documentation to make it available in :help and make the vim.loop module more discoverable. Thought plugin authors might be interested.

I'm assuming this one.

Nice! Someday I would love for babelfish to handle this, but I need to sit down and fix some of the parsing problems that cause it to skip over embedded lists and the like (Also blankspace is an issue).

You might be interested in md2vim , babelfish.nvim :)
