Hi Matabele,
Where items are being prepended, appended or removed from the list, there

I see, so you are required to specify the operand using text-references or
variables for multiple items.
I think it might be more consistent to use the same syntax of the list
filter here, e.g:
filter="[list[some-list]prepend:5[some-tiddler!!some-list]]
instead of:
filter="[list[some-list]prepend:5{some-tiddler!!some-list}]
Also, this should never do anything, it appears:
if (append === "") {
...as you have cast append into an array like so:
append = $tw.utils.parseStringArray(operator.operand);
Here's a test that does not do as I expect:
title: test
x: [[foo bar]] baz mumble frotz
y: [[aaaa bbbb]]] cccc mumble eeee
{{{ [list[!!x]append:3{!!y}] }}}
which outputs:
-
- foo bar
- baz
- mumble
- frotz
- aaaa bbbb]
- cccc
- mumble
But should output a set:
- foo bar
- baz
- frotz
- aaaa bbbb
- cccc
- mumble
In other words, it should work exactly the same as:
{{{ [list[!!x]] [[aaaa bbbb]] cccc mumble }}}
Should it not?
Same for using a variable *y* instead of a field *y*.
Best wishes,
— tb
