async-uv.nvim

Every libuv function that has a callback, now wrapped in async/await syntax. Other libuv functions are also exported for your convenience.

Installation

With Packer

 use { "ec965/async-uv.nvim", requires = { "ms-jpq/lua-async-await" }}

Usage

local uv = require "async-uv"
local a = require "async"

function readFile(path)
    return a.sync(function()
        local err, fd = a.wait(uv.fs_open(path, "r", 438))
        assert(not err, err)
        local err, stat = a.wait(uv.fs_fstat(fd))
        assert(not err, err)
        local err, data = a.wait(uv.fs_read(fd, stat.size, 0))
        assert(not err, err)
        return data
    end)
end

a.sync(function()
    local data = a.wait(readFile(vim.fn.expand "~/.config/nvim/init.lua"))
    vim.schedule(function()
        vim.notify(data)
    end)
end)()
