Problem:
Non-trivial to write output of vim.net.request to buffer. Requires extra
code in plugin/net.lua which can't be reused by other plugin authors.
```
vim.net.request('https://neovim.io', {}, function(err, res)
if not err then
local buf = vim.api.nvim_create_buf(true, false)
if res then
local lines = vim.split(res.body, '\n', { plain = true })
vim.api.nvim_buf_set_lines(buf, 0, -1, true, lines)
end
end
end)
```
Solution:
Accept an optional `outbuf` argument to indicate the buffer to write output
to, similar to `outpath`.
vim.net.request('https://neovim.io', { outbuf = buf })
Other fixes / followups:
- Make plugin/net.lua smaller
- Return objection with close() method
- vim.net.request.Opts class
- vim.validate single calls
- Use (''):format(...) instead of `..`
