lua-eco(中文)

Lua-eco is a Lua interpreter with a built-in event loop for scheduling lightweight coroutines automatically, enabling efficient concurrency in Lua. Build high-performance, scalable applications.

Lua-eco also provides some modules for you to build applications quickly:

• log: Provides logging functionality for Lua-eco applications, allowing you to log messages at different severity levels and output them to various destinations.
• time: Provides a Lua interface, allowing you to get current time, sleeping, performing timer operations.
• file: Provides a Lua interface, allowing you to read and write files, traverse directory and perform other file-related operations.
• sys: Provides access to various system-level functionality, such as process id, system information, and allows you to execute shell commands while obtaining their exit status as well as their standard output and standard error output.
• socket: Provides a low-level network socket interface for Lua-eco applications, allowing you to create and manage network connections. Includes tcp, tcp6, udp, udp6 and unix.
• ssl: Provides SSL/TLS support for Lua-eco applications, allowing you to establish secure connections to remote servers.
• http/https: Provides a HTTP client and server implementation for Lua-eco applications.
• websocket: Provides a WebSocket client and server implementation for Lua-eco applications, allowing you to build real-time web applications.
• mqtt: Provides an implementation of the MQTT 3.1.1 protocol for Lua-eco applications.
• dns: Provides a DNS client implementation for Lua-eco applications, allowing you to perform DNS lookups and resolve domain names.
• ubus: Provides a Lua interface to the ubus system in OpenWrt, allowing you to interact with system services and daemons.
• sync: Provides operations for synchronization between coroutines.
• netlink: Provides operations for inter-process communication (IPC) between both the kernel and userspace processes.
• nl80211: Show/manipulate wireless devices and their configuration.
• termios: Bind unix API for terminal/serial I/O.
• ssh: Bind libssh2.

Would you like to try it? Kinda interesting.

#!/usr/bin/env eco

local time = require 'eco.time'

eco.run(function(name)
    while true do
        print(time.now(), name, eco.id())
        time.sleep(1.0)
    end
end, 'eco1')

eco.run(function(name)
    while true do
        print(time.now(), name, eco.id())
        time.sleep(2.0)
    end
end, 'eco2')

lua-eco's Issues

Problem with compilation

Environment

• arch: x86_64
• os: GNU / Linux Debian
• version: testing

Description

It fails to compile:

/home/stefanos/development/sources/lua-eco/eco.c: In function ‘eco_resume’:
/home/stefanos/development/sources/lua-eco/eco.c:100:18: error: too few arguments to function ‘lua_resume’
  100 |     int status = lua_resume(co, L, narg);
      |                  ^~~~~~~~~~

make: *** [Makefile:136: all] Error 2

Yes, the error points at Lua 5.4, but I have tested it with 5.3 and produces the same error.

Also, I get this warning during cmake ..:

CMake Warning at CMakeLists.txt:108 (message):
  Not found libubus.  Skip build eco.ubus

idea: generated binaries for every platform?

The releases-section of https://github.com/nats-io/nats-server is a good example.
The .github-folder shows how to automatically generate binaries for each platform.

server.lua example no longer working because of bufio

/usr/local/lib/lua/5.3/eco/bufio.lua:239: "reader" must be a table
when running example server.lua
The c code seems to expect a number from getfd but
this happens:

    if type(reader) ~= 'table' then
        error('"reader" must be a table')
    end

/usr/local/lib/libeco.so not found

after fresh install on VPS libeco.so not found
Could -Wl,-rpath=/usr/local/lib be added at compile time please.
I know its my problem with LD_LIBRARY_PATH but if you
know it will be installed at /usr/local/lib it won't hurt.
