Here's what I've tried so far and here's the results if it helps any to get
me on the right track, plus I hope this helps someone else looking for this
to because this is something very commonly done in PHP.
I have tried changing this:
response.menu3[-1]+=([[(T(subcat.subcategory)), False, 'link',]])
to this:
response.menu3[-1]+=([(T(subcat.subcategory)), False, 'link',])
Which changes the output in the shell to:
[<lazyT 'Catalog'>,
False,
'',
[<lazyT 'Animals'>,
False,
'link',
<lazyT 'Dogs'>,
False,
'link',
<lazyT 'Cats'>,
False,
'link']]
Which obviously isn't correct.
Continuing:
original:
response.menu3[-1]+=([[(T(subcat.subcategory)), False, 'link',]])
to this:
response.menu3+=([[(T(subcat.subcategory)), False, 'link',]])
Gives this in the shell output:
[<lazyT 'Catalog'>,
False,
'',
[<lazyT 'Animals'>, False, 'link'],
[<lazyT 'Dogs'>, False, 'link'],
[<lazyT 'Cats'>, False, 'link']]
Again obviously incorrect. Continuing:
original:
response.menu3+=([[(T(subcat.subcategory)), False, 'link',]])
changed:
response.menu3[-1]+=((T(subcat.subcategory)), False, 'link',)
Shell output shows:
[<lazyT 'Catalog'>,
False,
'',
[<lazyT 'Animals'>,
False,
'link',
<lazyT 'Dogs'>,
False,
'link',
<lazyT 'Cats'>,
False,
'link']]
I tried additional variations but, not sure how much space we have here to
keep going with my 2 weeks worth of work. Essentially the end result is
the same a bracket missing to seperate the subcategories. I've been able
to modify and add to lists before, however I've never really experienced a
situation where the negative slice appears to be ignored (removing the
bracket at the end of dogs and beginning of cats as it is doing for the
main category Animals as can be seen), even removed the negative slice
([-1]) for the main categories iteration and when I do it clearly shows
that it is actually doing the negative slice properly because the brackets
come back at the end of Animals, unlike the subcategories that do not
appear to be removing the bracket(s)
