"Item Count" property for CCs?

[TheQwerty]

I would think ListFolder would be a bit quicker for counting items:

Code: Select all

$d = GetToken(ListFolder("<cc_item>", '*', 2), 'Count', '|'); // Directory count.
$f = GetToken(ListFolder("<cc_item>", '*', 1), 'Count', '|'); // File count.
return "$d Dirs, $f Files";

[/size]There's no need to check <cc_isfolder> since you can just set the column's item type setting to Folders only - which should give a nice speed boost since XY won't have to run the script at all on Files.


Likewise, there's no need to use regexreplace with FolderReport to get extensions - just use the template value:

Code: Select all

$sep = '; '; // Separator to use in the list.
$f = FolderReport('files:{ext}', 'r', "<cc_item>",,,$sep); // List of extensions.
$n = GetToken($f, 'Count', $sep); // Count of files.
if ($n < 1) {
  return "F: 0"; // If no files omit extensions.
} else {
  $f = FormatList($f, 'dnts', $sep); // Clean up extension list.
  if ($f Like "$sep*") { $f = "<none>$f"; } // If the first item is empty add some text for non-extensions.
  $f = FormatList($f, 'e', $sep); // Remove all empties now that the first is changed.
  return "$f, F: $n";
}

Don, shame these snippets do not seem to work with the Snippet SC.

For this they would need a reference as to which of the 32 CC definitions should be set. Difficult to share among users...

Why don't we have this same issue with CTBs?

Uhm... I'll tell you tomorrow...

By the way: in help:

- gettoken() shows all operands as quoted - in Syntay as well as in Examples, while
- gettokenindex() shows operands quoted in Examples, while in Syntax separator and flags are shown unquoted...
(Sometimes users use a strange way of quoting )

Well, I think that's okay to show it unquoted in the syntax. Saves space, and ultimately the climate.

Sorry - I've missed this reply

And sorry, but in terms of quoting the Syntax-Definition
gettokenindex(token, tokenlist, [separator=|], [flags=iw]);
is just wrong. And people will (sometimes) use it as a model.
And it (sometimes) will lead people to learn bad/wrong quoting...
(Yes: they *might* read the examples )

Just my opinion.

Funny - with
gettoken(string, [index=1], [separator=" "], [format], [flags])
you made it correct for separator

Did you configure the column correctly?

i guess yes

Hi!
Thanks for the pointers. The listfolder() method seems to be a bit faster, but I'm yet to find a machine processing templates fast enough: in the same backup folder I was operating, your version froze XY instance for almost 50 secs against 10 from my original script. At first I thought it was recursing the whole subfolders structure, but it's not. On the other hand, it seems to avoid a problem I had with files without a extension. Have to study this.

Yes, I'm learning some tricks to reduce operations to a minimum as CCs demand some care to not interfere on list browsing. I'm even appealing to nesting operations. It's not didactic at all, but seems to be a way to minimize impact on performance.

OK, SC snippet will work with Custom Column snippets in next version. It will find the next undefined column and define it. Undocumented. Snippets are officially still *planned*.

Indeed... Looks like a fundamental difference between ListFolder and FolderReport. The former shows error dialogs and the latter returns an empty string, so unfortunately neither can get you 100% of the way there. At least FolderReport is more graceful when it fails.
