Makefile to reflect your
installation of Lua. Then run make. This will build the library and run a simple test.
syslog.so somewhere in your
LUA_CPATH.
openlog(ident, option[, facility])
syslog(priority, message)
closelog()
See test.lua, which shows the library in action.
You may want to wap the standard assert and
error Lua calls so that they log the assertion or error before
aborting the program. This can be useful for post-mortem analysis of
embedded or unattended Lua applications. You can append this code at the end of
strict.lua, a module that can be found in the
etc directory of the Lua sources, and which is worth including
anyway.
require "syslog"
-- set the ident string to the filename that first included this module
syslog.openlog(debug.getinfo(3, "S").short_src, syslog.LOG_ODELAY, "LOG_USER")
local _error = error
error = function(txt, level)
if level then level = level + 1
else level = 2
end
local info = debug.getinfo(level, "Sl")
local msg
if info.what == "C" then
msg = "[C function] "
else
msg = string.format("[%s]:%d ", info.short_src, info.currentline)
end
syslog.syslog("LOG_ERR", msg .. (txt or ""))
_error(txt, level)
end
_G.assert = function (...)
local cond, txt = ...
if not cond then
error(txt or "assertion failed!", 2)
end
return ...
end
Then call require "strict" at the top of your code.
