#set directive: Assignment value lost after foreach loop about airspeed

[purcell]

What should the behaviour of this be? -

#set($i = 1)
#foreach ($i in [1,2,3])#end
$i

If I know that, I can figure out how best to fix it. I don't have an official Velocity lying around to test it with. :-)

Hey, thanks for the quick answer.

I just ran a quick test with the official engine: In this case the variable outside the foreach block stays untouched and is rendered with the same value as above the foreach block. Like in this test case (which currently succeeds): flofuchs@a4b763c

def test_no_assignment_to_outer_var_if_same_varname_in_block(self):
    template = airspeed.Template(
        "#set($i = 1)$i,"
        "#foreach ($i in [2, 3, 4])$i,#set($i = $i)#end"
        "$i")
    self.assertEquals("1,2,3,4,1", template.merge({}))

Done, and released in 0.5.2. Let me know if you experience any issues.

Awesome, thanks a ton!
