Loops may be started by applying the rep function to a block:
[rep:x]{content to repeat}
where x is the number of times to repeat the loop.
[rep:3]{ha}
will produce:
hahaha
All normal Twaddle features, such as Lookups or branching can be used within a loop.
Does nothing if x is 1 or less.
Lookups and branching can be used within loops. The lookups and branching path will be chosen anew in each iteration of the loop:
[rep:3][sep:, ]{<noun>|<adv> <verb.ing>}
may give:
possibly hammering, falconer, quietly organizing
If the loop should return the same branch each iteration, this can be achieved by using a locked synchronizer. Similarly, if the lookup result should remain the same across iterations, this can be achieved by applying a label
A number of other functions exist to extend the loop functionality, these are
placed between the rep function and the block to which it applies.
A separator can be defined, which will be output between each instance of
the loop. This is done using the sep function:
[rep:3][sep:, ]{more}!
produces:
more, more, more!
The first defines text which should be output before the first instance of
the loop:
[rep:3][first:don't ]{go! }:
producing:
don't go! go! go!
The last defines text which should be output before the last instance of
the loop:
[rep:3][last:don't ]{go! }:
producing:
go! go! don't go!
