Zettelmarkup: Mark
A mark allows to name a point within a zettel. This is useful if you want to reference some content in a zettel, either with a link or with an inline-mode transclusion.
A mark begins with a left square bracket, followed by an exclamation mark character (!
, U+0021). Now the optional mark name follows. It is a (possibly empty) sequence of Unicode letters, Unicode digits, the hyphen-minus character (-
, U+002D), or the low-line character (_
, U+005F). An optional text to be explicitly marked is introduced with a vertical bar character (|
, U+007C), followed by some inline-structured elements. The mark element ends with a right square bracket.
Examples:
[!]
is a mark without a name, the empty mark.[!mark]
is a mark with the namemark
.[!|some text]
is the empty mark withsome text
.[!mark|some text]
is a mark with the namemark
and withsome text
that is marked.
