@ -9,6 +9,18 @@ expression to generate the value.
An expression will contain some directives wrapped in `{}` characters. Within
`{}` are a number of potential substitute values and operations.
Note that syntax of expressions can have overlap with the shell syntax.
For example:
`$ echo (n2)`
`-bash: syntax error near unexpected token `n2'`
In such a case, it helps to quote the expression to allow it to be passed:
`$ echo '(n2)'`
`(n2)`
The most common operation is to extract a number from the nodename. These
values are available as n1, n2, etc. So for example attributes for a node named
b1o2r3u4 would have {n1} as 1, {n2} as 2, {n3} as 3, and {n4} as 4.
