NAME

-lua - Lua interpreter -

SYNOPSIS

-lua -[ -options -] -[ -script -[ -args -] -] -

DESCRIPTION

-lua -is the stand-alone Lua interpreter. -It loads and executes Lua programs, -either in textual source form or -in precompiled binary form. -(Precompiled binaries are output by -luac, -the Lua compiler.) -lua -can be used as a batch interpreter and also interactively. -

-The given -options -(see below) -are executed and then -the Lua program in file -script -is loaded and executed. -The given -args -are available to -script -as strings in a global table named -arg. -If these arguments contain spaces or other characters special to the shell, -then they should be quoted -(but note that the quotes will be removed by the shell). -The arguments in -arg -start at 0, -which contains the string -`script'. -The index of the last argument is stored in -"arg.n". -The arguments given in the command line before -script, -including the name of the interpreter, -are available in negative indices in -arg. -

-At the very start, -before even handling the command line, -lua -executes the contents of the environment variable -LUA_INIT, -if it is defined. -If the value of -LUA_INIT -is of the form -`@filename', -then -filename -is executed. -Otherwise, the string is assumed to be a Lua statement and is executed. -

-Options start with -- -and are described below. -You can use -"--" -to signal the end of options. -

-If no arguments are given, -then -"-v -i" -is assumed when the standard input is a terminal; -otherwise, -"-" -is assumed. -

-In interactive mode, -lua -prompts the user, -reads lines from the standard input, -and executes them as they are read. -If a line does not contain a complete statement, -then a secondary prompt is displayed and -lines are read until a complete statement is formed or -a syntax error is found. -So, one way to interrupt the reading of an incomplete statement is -to force a syntax error: -adding a -`;' -in the middle of a statement is a sure way of forcing a syntax error -(except inside multiline strings and comments; these must be closed explicitly). -If a line starts with -`=', -then -lua -displays the values of all the expressions in the remainder of the -line. The expressions must be separated by commas. -The primary prompt is the value of the global variable -_PROMPT, -if this value is a string; -otherwise, the default prompt is used. -Similarly, the secondary prompt is the value of the global variable -_PROMPT2. -So, -to change the prompts, -set the corresponding variable to a string of your choice. -You can do that after calling the interpreter -or on the command line with -"_PROMPT" "=\'lua: \'", -for example. -(Note the need for quotes, because the string contains a space.) -The default prompts are ``> '' and ``>> ''. -

OPTIONS

-- -load and execute the standard input as a file, -that is, -not interactively, -even when the standard input is a terminal. -

--e "stat" -execute statement -stat. -You need to quote -stat -if it contains spaces, quotes, -or other characters special to the shell. -

--i -enter interactive mode after -script -is executed. -

--l "file" -call -require( file) -before executing -script. -Typically used to load libraries -(hence the letter -l). -

--v -show version information. -

DIAGNOSTICS

-Error messages should be self explanatory. -
