<<.place space>> denotes a sequence of [[whitespace characters|Filter Whitespace]].
|
|
|
|
The [[macro|Macros]]'s <<.place name>> is a sequence of non-whitespace characters other than `(` or `>`.
|
|
|
|
Each individual <<.place param-value>> has the following syntax:
|
|
|
|
<$railroad text="""
|
|
[: param-name [:space] ":" [:space] ] value [: space]
|
|
"""/>
|
|
|
|
The <<.place param-name>> is a sequence of letters (`A`--`Z`, `a`--`z`), digits (`0`--`9`), hyphens (`-`) and underscores (`_`).
|
|
|
|
The <<.place value>> is specified as follows:
|
|
|
|
<$railroad text={{$:/editions/tw5.com/railroad/macro-parameter-value}}/>
