This help-page, Help:Lua debugging, explains issues of writing Lua script and debugging the source code, to remove errors or improve performance. Because Lua is a "semi-compiled" interpreted language, it does not prescreen for all common syntax errors, nor detect misspelled variables, which are only found at runtime when seeing the " Script ...
Lua discards the first newline (if present) that directly follows the opening tag. Perl. Block comments in Perl are considered part of the documentation, and are given the name Plain Old Documentation (POD). Technically, Perl does not have a convention for including block comments in source code, but POD is routinely used as a workaround. PHP
This text calls the Lua script itself, which is housed in the Module: namespace. The effect of this call is to send the information within the #invoke block to the Lua module, and to replace everything within the brackets with a piece of text that it sends back in return. (Literally, in the "return" statement)
Most languages support multi-line block (a.k.a. stream) and/or single line comments. A block comment is delimited with text that marks the start and end of comment text. It can span multiple lines or occupy any part of a line. Some languages allow block comments to be recursively nested inside one another, but others do not.
This page explains different methods for creating, controlling and preventing line breaks and word wraps in Wikipedia articles and pages.. When a paragraph or line of text is too long to fit on one line, web browsers, like many other programs, automatically wrap the text to the next line.
For example, in Python, raw strings are preceded by an r or R – compare 'C:\\Windows' with r'C:\Windows' (though, a Python raw string cannot end in an odd number of backslashes). Python 2 also distinguishes two types of strings: 8-bit ASCII ("bytes") strings (the default), explicitly indicated with a b or B prefix, and Unicode strings ...
This allows the block opener ({or BEGIN) to be skipped for all but the function level block, requiring only a block terminating token (} or END). It also fixes dangling else . Custom is for the end token to be placed on the same indent level as the rest of the block, giving a blockstructure that is very readable.
Almost any problem which occurs when running a Lua module will be reported as "Script error" during program execution, such as invalid data or a misspelled variable name in the Lua source code.
