This directory contains code that is more useful than the
samples. This code *is* supported.
tftp.lua -- Trivial FTP client
This module implements file retrieval by the TFTP protocol.
Its main use was to test the UDP code, but since someone
found it usefull, I turned it into a module that is almost
official (no uploads, yet).
dict.lua -- Dict client
The dict.lua module started with a cool simple client
for the DICT protocol, written by Luiz Henrique Figueiredo.
This new version has been converted into a library, similar
to the HTTP and FTP libraries, that can be used from within
any luasocket application. Take a look on the source code
and you will be able to figure out how to use it.
lp.lua -- LPD client library
The lp.lua module implements the client part of the Line
Printer Daemon protocol, used to print files on Unix
machines. It is courtesy of David Burgess! See the source
code and the lpr.lua in the examples directory.
b64.lua
qp.lua
eol.lua
These are tiny programs that perform Base64,
Quoted-Printable and end-of-line marker conversions.
get.lua -- file retriever
This little program is a client that uses the FTP and
HTTP code to implement a command line file graber. Just
run
lua get.lua <remote-file> [<local-file>]
to download a remote file (either ftp:// or http://) to
the specified local file. The program also prints the
download throughput, elapsed time, bytes already downloaded
etc during download.
check-memory.lua -- checks memory consumption
This is just to see how much memory each module uses.
dispatch.lua -- coroutine based dispatcher
This is a first try at a coroutine based non-blocking
dispatcher for LuaSocket. Take a look at 'check-links.lua'
and at 'forward.lua' to see how to use it.
check-links.lua -- HTML link checker program
This little program scans a HTML file and checks for broken
links. It is similar to check-links.pl by Jamie Zawinski,
but uses all facilities of the LuaSocket library and the Lua
language. It has not been thoroughly tested, but it should
work. Just run
lua check-links.lua [-n] {<url>} > output
and open the result to see a list of broken links. Make sure
you check the '-n' switch. It runs in non-blocking mode,
using coroutines, and is MUCH faster!
forward.lua -- coroutine based forward server
This is a forward server that can accept several connections
and transfers simultaneously using non-blocking I/O and the
coroutine-based dispatcher. You can run, for example
lua forward.lua 8080:proxy.com:3128
to redirect all local conections to port 8080 to the host
'proxy.com' at port 3128.
unix.c and unix.h
This is an implementation of Unix local domain sockets and
demonstrates how to extend LuaSocket with a new type of
transport. It has been tested on Linux and on Mac OS X.
Good luck,
Diego.
