Problem:
Nvim depends on netrw to download/request URL contents.
Solution:
- Add `vim.net.request()` as a thin curl wrapper:
- Basic GET with --silent, --show-error, --fail, --location, --retry
- Optional `opts.outpath` to save to a file
- Operates asynchronously. Pass an `on_response` handler to get the result.
- Add integ tests (requires NVIM_TEST_INTEG to be set) to test success
and 404 failure.
- Health check for missing `curl`.
- Handle `:edit https://…` using `vim.net.request()`.
API Usage:
1. Asynchronous request:
vim.net.request('https://httpbingo.org/get', { retry = 2 }, function(err, response)
if err then
print('Fetch failed:', err)
else
print('Got body of length:', #response.body)
end
end)
2. Download to file:
vim.net.request('https://httpbingo.org/get', { outpath = 'out_async.txt' }, function(err)
if err then print('Error:', err) end
end)
3. Remote :edit integration (in runtime/plugin/net.lua) fetches into buffer:
:edit https://httpbingo.org/get
