Template:Emdash/doc
This is the mdash template, it looks like this " — ".
It works similarly to the html markup sequence " — ". That is, a non-breaking space, a long dash (known as an em dash) and a normal space.
{{—}} and {{emdash}} redirect here and can be used as alternative names for this template.
This template is used when you want something a lot stronger than a bold middot "·", a bullet "•" or a ndash "–".
Normal usage
The recommended usage is to use no space before the template and one space after the template, like this:
[[Salt]]{{mdash}} [[Pepper]]
It will render one space on each side of the dash, like this:
If it line breaks then the line break will come after the dash, not before, like this:
For long dashed lists each list item can be put on its own line, with no spaces between each item and the template. Like this:
[[Salt]]{{mdash}}
[[Pepper]]{{mdash}}
[[Curry]]{{mdash}}
[[Saffron]]
(It doesn't matter if there are no or some spaces at the end of the lines, after the templates.)
As before it will render one space on each side of the dashes, like this:
And if it line breaks then the line break will come after one of the dashes, not before, like this:
But really, you should use bold middots "·" or ndashes "–" for such lists.
Incorrect usage
If the template is used slightly wrong it will in some cases still behave well. For instance if there are no or several spaces after the template. Like these examples:
[[Salt]]{{mdash}}[[Pepper]]
[[Salt]]{{mdash}} [[Pepper]]
Both of them will render exactly as before, with just one space on each side of the dash, like this:
And it will still only line break after the dash, like this:
But putting one or more spaces before the template will cause problems, like these examples:
[[Salt]] {{mdash}}[[Pepper]]
[[Salt]] {{mdash}}[[Pepper]]
[[Salt]] {{mdash}} [[Pepper]]
[[Salt]] {{mdash}} [[Pepper]]
Then it will render with two spaces before the dash, and one after, like this:
And if it line breaks it might break before the dash, like this:
