My customized 'Enter' key handler, for lister

Hi there

This is my customized 'Enter' key handler , for lister

  • it there is an only one selected dir, it opens it
  • it there is any file selected that belongs to some (currently hardcoded) filetype groups,
    particulary image OR movie OR ... (music) ; it opens the standalone viewer
  • otherwise it fallbacks to default dblclk

I found the mismatch between image and movie to launch the standalone viewer was very annoying for me. I can not get anything up with @if @ifset etc

So here it is

function OnClick(clickData) {
    var cmd = clickData.func.command;
    cmd.deselect = false;
    var srctab = clickData.func.sourcetab;
    if ((srctab.selected_dirs.count == 1) && (srctab.selected_files.count == 0))
        cmd.RunCommand("Go FROMSEL");
    else if(_match_ftgrp(srctab.selected_files))
        cmd.RunCommand("Show AUTOFILELIST");
    else
        cmd.RunCommand("FileType ACTION=shellex"); }

var _FTGRP_NAMES = ["2D Images", "3D Images", "Movies", "Music"];
function _match_ftgrp(seld_files) {
    return any(seld_files, function(seld_f) {
        return any(_FTGRP_NAMES, function(ftgrp_name) {
            ftgrp = DOpus.filetypegroups.GetGroup(ftgrp_name);
            return ftgrp.MatchExt(seld_f.name); }); }); }

// high order funcs
function any(coll, func) {
    ok = false;
    for (var e=new Enumerator(coll), item=e.item(); !ok && !e.atEnd(); e.moveNext(), item=e.item()) {
        ok = func(item); }
    return ok; }

// v unused, free gift
function foreach(coll, func) {
    for (var e=new Enumerator(coll), item=e.item(); !e.atEnd(); e.moveNext(), item=e.item()) {
        func(item); } }

function map(coll, func) {
    var res = [];
    for (var e=new Enumerator(coll), item=e.item(); !e.atEnd(); e.moveNext(), item=e.item()) {
        res.push(func(item)); }
    return res; }

SEE
