Expected Behavior
loop.revindex should be 1 when using a reversed iterator of length 1
jinja2.Template("{% for i in lst|reverse %}{{ loop.revindex }}:{{ i }}, {% endfor %}")
.render(lst=[10])should print out: '1:10, '
Actual Behavior
The index of the only iteration is set to 2
jinja2.Template("{% for i in lst|reverse %}{{ loop.revindex }}:{{ i }}, {% endfor %}")
.render(lst=[10])prints out: '2:10, '
However:
jinja2.Template("{% for i in lst|reverse %}{{ loop.revindex }}:{{ i }}, {% endfor %}")
.render(lst=[10, 11])correctly prints out: '2:11, 1:10, '
Template Code
{% for i in lst|reverse %}{{ loop.revindex }}:{{ i }}, {% endfor %}Your Environment
