For

Many programming languages support the notion of a "for" loop. In the most simple use case one could give, a for loop is a way to repeatedly execute a piece of code n times.

Technically a for loop advances through a sequence (e.g. all odd numbers, all even numbers, every nth number, etc), giving the programmer greater control over the seed value (or "index") of each iteration through the loop.

Attributes:

• var (optional)

  If assigned, the current 'index' of the loop is assigned to this template variable.

• from (optional; default "0")
• start

  Identifies the starting number for the loop.

• to
• end

  Identifies the ending number for the loop. Either 'to' or 'end' must be specified.

• step (optional; default "1")
• increment

  Provides the amount to increment the loop counter.

• glue (optional)

  If specified, this string is added inbetween each block of the loop.

Within the tag, the following variables are assigned:

• __first__

  Assigned 1 when the loop is in the first iteration.

• __last__

  Assigned 1 when the loop is in the last iteration.

• __odd__

  Assigned 1 when the loop index is odd, 0 when it is even.

• __even__

  Assigned 1 when the loop index is even, 0 when it is odd.

• __index__

  Holds the current loop index value, even if the 'var' attribute has been given.

• __counter__

  Tracks the number of times the loop has run (starts at 1).

Example:

    <mt:For from="2" to="10" step="2" glue=","><$mt:Var name="__index__"$></mt:For>
