Template:Newline/doc
The {{newline}} template produces a newline in the wikitext that will not be stripped by a whitespace left-trim operation, e.g., at the beginning of the "then" or "else" parts of #if
: see Help:Extension:ParserFunctions § Stripping whitespace.
This template can also be useful simply to make a significant newline visible.
Newlines in wikitext are important when generating tables, for example. Many bits of wikitext table syntax, such as |-
and |
, must come at the beginning of a line (ignoring leading spaces): see Help:Tables.
This template is not quite "pure": it expands to <nowiki/>
followed by a newline. This has two effects:
- It leaves a
<nowiki/>
at the end of the preceding line. I don't know of any problems that this can cause. - The newline at the end is not "protected" by anything, so it will be stripped by a whitespace right-trim operation, e.g., at the end of the "then" or "else" parts of
#if
.
A workaround for the latter is to add a <nowiki/>
afterward. If this were done in the {{newline}} template itself, however, it would destroy the usefulness of this template for creating tables: something like {{newline}}|-
would put a <nowiki/>
before the |-
, which is not allowed.
