Used for iterating over sections of the template tags.
Can be used to pull values from config into a powershell variable.
$instances = ("{% for instance in PropertyGroupLabel %}{{ instance.identity }};{% endfor %}" | ensconce -i).Split(";") | Where-Object { $_ -ne "" }
For loops have context variables which can be used
| Variable | Description |
|---|---|
forloop.counter |
The current iteration of the loop (1-indexed) |
forloop.counter0 |
The current iteration of the loop (0-indexed) |
forloop.revcounter |
The number of iterations from the end of the loop (1-indexed) |
forloop.revcounter0 |
The number of iterations from the end of the loop (0-indexed) |
forloop.first |
True if this is the first time through the loop |
forloop.last |
True if this is the last time through the loop |
These can be used to extend the example above
$instances = ("{% for instance in PropertyGroupLabel %}{{ instance.identity }}{% if not forloop.last %};{% endif %}{% endfor %}" | ensconce -i).Split(";") | Where-Object { $_ -ne "" }
Which will not include the ; at the end and only between each item.
