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).
Spaces within a formula must be directly managed (for example by including explicit hair or thin spaces). Variable names must be italicized explicitly, and superscripts and subscripts must use an explicit tag or template. Except for short formulas, the source of a formula typically has more markup overhead and can be difficult to read.
It specifies where it would be OK to add a line-break where a word is too long, or it is perceived that the browser will break a line at the wrong place. Whether the line actually breaks is then left up to the browser. The break will look like a space - see soft hyphen below when it would be more appropriate to break the word or line using a ...
Functions can return any kind of value — including a function. This is a powerful feature that can readily confuse the beginner. If you set a = mw. ustring. gmatch (text, "(.)"), the result assigned to a will be a function, not a string character! However, assigning b=a() by calling the function stored in a will return
A newline character sequence typically moves the render output location to the beginning of the next line. If one follows text, it does not actually result in whitespace. But, two sequential newline sequences between text blocks results in a blank line between the blocks. The height of the blank line varies by application.
Invalid function name: len = string.long(my_str) - The string-length operator is hash mark '#' (as in: #my_str), or use function 'string.len(my_str)' but trying to use unknown function 'string.long(my_str)' will successfully pass during the pre-compile of edit-save, yet it will hit "Script error" when that portion of the Lua script is executed.
A second common application of non-breaking spaces is in plain text file formats such as SGML, HTML, TeX and LaTeX, whose rendering engines are programmed to treat sequences of whitespace characters (space, newline, tab, form feed, etc.) as if they were a single character (but this behavior can be overridden).
Lua (as of 5.1) provides a limited form of multiple quoting, particularly to allow nesting of long comments or embedded strings. Normally one uses [[ and ]] to delimit literal strings (initial newline stripped, otherwise raw), but the opening brackets can include any number of equal signs, and only closing brackets with the same number of signs ...
