+.Sh NAME
+.Nm style.lua
+.Nd
+.Fx
+lua file style guide
+.Sh DESCRIPTION
+This file specifies the preferred style for lua source files in the
+.Fx
+source tree.
+Many of the style rules are implicit in the examples.
+Be careful to check the examples before assuming that
+.Nm
+is silent on an issue.
+.Pp
+The copyright header should be a series of single-line comments.
+Use the single-line comment style for every line in a multi-line comment.
+.Pp
+After any copyright header, there is a blank line, and the
+.Li $\&FreeBSD$
+comment for non-C/C++ source files.
+.Pp
+The preferred method of including other files and modules is with
+.Fn require name ,
+such as:
+.Bd -literal
+-- $FreeBSD$
+
+config = require("config");
+menu = require("menu");
+password = require("password");
+-- One blank line following the module require block
+.Ed
+.Pp
+.Fn include
+is generally avoided.
+.Pp
+Indentation and wrapping should match the guidelines provided by
+.Xr style 9 .
+.Pp
+Statements should be terminated with a semicolon.
+.Ic end
+should not be terminated with a semicolon.
+.Pp
+Where possible,
+.Fn s:method ...
+is preferred to
+.Fn method s ... .
+This is applicable to objects with methods.
+String are a commonly-used example of objects with methods.
+.Pp
+Testing for
+.Va nil
+should be done explicitly, rather than as a boolean expression.
+Single-line conditional statements and loops should be avoided.
+.Pp
+.Ic local
+variables should be preferred to module scope variables.
+.Pp
+Multiple local variables should not be declared
+.Sy and
+initialized on a single line.
+Lines containing multiple variable declarations without initialization are ok.
+Lines containing multiple variable declarations initialized to a single function
+call returning a tuple with the same number of values is also ok.
+.Pp
+Initialization
+.Sy should
+be done at declaration time as appropriate.
