7 years ago I suppose I should have included some code to replicate it. This is code that is confirmed to have worked not that long ago. I should add, I'm on the latest of everything, luvit, luvi, lit, coro-spawn, coro-split, etc. The purpose of this script is to auto-restart and send all data to a log file.
-- example: luvit starter.lua file.lua
local fs = require('coro-fs')
local timer = require('timer')
local spawn = require('coro-spawn')
local split = require('coro-split')
local fmt = '!%Y-%m-%d %H:%M:%S'
local cmd = args[0]
args[0] = nil
table.remove(args, 1)
coroutine.wrap(function()
while true do
pcall(function()
local log = fs.open(args[1]:gsub('.lua', '.log'), 'a')
local child = spawn(cmd, {
args = args,
stdio = {nil, true, true}
})
split(function()
local line = {nil, ' ', nil}
for data in child.stdout.read do
line[1] = os.date(fmt)
line[3] = data
fs.write(log, line)
print(unpack(line))
end
end, function()
local line = {nil, ' ', nil}
for data in child.stderr.read do
line[1] = os.date(fmt)
line[3] = data
fs.write(log, line)
print(unpack(line))
end
end, child.waitExit)
fs.close(log)
timer.sleep(5000)
end)
end
end)()

I get a process id and a child.handle, and it prints in the stdout and stderr to say it skipped the stdout.read and didn't continue to read until the child exited. Also, I don't know that this will help, but here's my line that uses coro-split that should process everything.
split(readstdout, readstderr, servant.waitExit)
