Working with str-list options

Help
1

Is it possible to work with a str-list option like a stack or array?

Is this option type effectively just a string that you can concat to with set -add?

If I add several string values that each may contain spaces to a str-list, then is it possible to retrieve, say, the first item?

This post seems like a good reference for implementing pushing/popping to a str-list, but also seems to confirm my suspicion that you’d have to manually manage the format of each item added to the list.

Based on the previously referenced example, this is a minimal demonstration for working with with str-list options via shell expansion:

define-command example_str_list_consumer %{
    declare-option str-list mystrlst
    set-option global mystrlst

    set-option -add global mystrlst "list item 1"
    set-option -add global mystrlst "list item 2"

    evaluate-commands %sh{
        eval "set -- $kak_quoted_opt_mystrlst"
        printf "echo -debug ''\n"
        printf "echo -debug 'arg count: %s'\n" "$#"
        printf "echo -debug 'all args: %s'\n" "$*"
        printf "echo -debug 'arg 1: %s'\n" "$1"
        printf "echo -debug 'arg 2: %s'\n" "$2"
        printf "buffer *debug*\n"
    }
}

This will open the debug buffer with the following entries:


arg count: 2
all args: list item 1 list item 2
arg 1: list item 1
arg 2: list item 2

When referenced in this way, each item in the str-list option is preserved, spaces and all!
