#for $var in EXPR #end for
#for directive iterates through a sequence. The syntax is the same
as Python, but remember the
$ before variables.
Here's a simple client listing:
<TABLE> #for $client in $service.clients <TR> <TD>$client.surname, $client.firstname</TD> <TD><A HREF="mailto:$client.email" >$client.email</A></TD> </TR> #end for </TABLE>
Here's how to loop through the keys and values of a dictionary:
<PRE> #for $key, $value in $dict.items() $key: $value #end for </PRE>
Here's how to create list of numbers separated by hyphens. This ``#end for'' tag shares the last line to avoid introducing a newline character after each hyphen.
#for $i in range(15) $i - #end for
If the location of the
#end for offends your sense of indentational
propriety, you can do this instead:
#for $i in $range(15) $i - #slurp #end for
The previous two examples will put an extra hyphen after last number. Here's
how to get around that problem, using the
#set directive, which will be
dealt with in more detail below.
#set $sep = '' #for $name in $names $sep$name #set $sep = ', ' #end for
Although to just put a separator between strings, you don't need a for loop:
#echo ', '.join($names)
