  • Command instead of dict for

    From Cecil Westerhof@21:1/5 to All on Sat May 7 06:39:23 2022
    To transform a dict to a list of list I use:
    set swapList {}
    dict for {name swap} ${swapDict} {
    lappend swapList [list $name $swap]
    }

    But I seem to remember that there is a command that does this, but I
    do not remember the command.
    Am I mistaken? If not: what is the command?

    Are you looking for [lmap {k v} {a b c d e f} {list $k $v}]? Note that this shimmers from dict to list:

    expect:~$ set d [dict create a b c d e f]
    a b c d e f
    expect:~$ ::tcl::unsupported::representation $d
    value is a dict with a refcount of 4, object pointer at 0xcaf7d0, internal representation 0xcf4570:(nil), string representation "a b c d e f"
    expect:~$ lmap {k v} $d {list $k $v}
    {a b} {c d} {e f}
    expect:~$ ::tcl::unsupported::representation $d
    value is a list with a refcount of 4, object pointer at 0xcaf7d0, internal representation 0xd343d0:(nil), string representation "a b c d e f"
