lsocket: simple and easy socket support for lua
What is it?
lsocket is a library to provide socket programming support for lua. It is not intended to be a complete socket api, but easy to use and good enough for most tasks. Both IPv4 and IPv6 are supported, as are tcp and udp, and also IPv4 broadcasts and IPv6 multicasts. Also, lsocket is almost nonblocking, meaning that nothing blocks except for nameserver lookups.
What's new in version 1.4.1 (2017-03-16)
- Fixed memory leak discovered by 云风 Cloud Wu
- proper tostring method
What's new in version 1.4 (2015-04-17)
- Lua 5.3 compatibility (or rather, some cleanup in the number handling department)
- socket fd's are checked against FD_SETSIZE now in select()
- changed build type to make
- converted all documentation to markdown
- fixed bug: send and sendto would not correctly return false on timeout (patch by 云风)
- lsocket README file
- README for the experimental async_resolver library
- what has changed from version to version.
There is also a mercurial repository at https://hg.tset.de/public/lsocket which is read-only, but also gets changes I make between the releases.
The lsocket module and all accompanying documentation and additional source code is released under the terms of the MIT license.
