nerdweed wrote:2. As the scripts for custom column, run per file, how do you run a section of code only once. My scripted column pulls data from a file for that folder (intended to do once - cache it) and then works out values for individual files from that cached. I tried two methods, and don't like them much
a. Time Difference - If the code was run within the previous 60 seconds, don't run that global piece of code. Otherwise run that piece of code and update the previous run time. (Thanks to TheQwerty)
b. Folder Path - Set a perm variable to the current folder path. If the path is different run the global code and update the perm var.

I hate method a, because it is difficult to identify, if it is working on stale cache (cache was for a different folder)
Method b is disliked, because I need to unset the variable if the contents of the files are changed or else it continues to work on a stale cache.

Obvious solution would be try a combination of both, but it would almost double the time for script execution and hence cancelled out.

Do you have some other tricks in your sleeves.

A combination of the two shouldn't necessarily double the execution time, it will be longer but it all depends on what you're using to identify the running instance/when to trigger the resource heavy portion of the script.

Instead of the time difference you could use the Folder Path + the data file's modification time or if it is small enough its hash. You could then track this for multiple paths in a permanent variable or a separate data file - but you'll need to play around a bit to figure out what you find as an acceptable speed trade-off.

A not very good option would be to use the PFADefaultOpenFolders tweak and then you can define a PFA for the folder (or all folders) and have a script run when you open that folder. This has its own shortcomings though as it will only run when you open the folder - browsing via Favorites/Address Bar/Tree/anything that does a goto won't trigger the script. Then when "opening" the folder you parse the file, update Extra Tags, and then goto the folder.

Maybe a new Custom Column script type of "Run-Once Script" could be introduced, but this needs some thought into how it plays with the trigger modes and search results/listings from multiple locations. I imagine eventually CEA could improve things but only time will tell.

I trust you mean "Run-Once" section in each script rather than trigger because it doesn't make sense as a trigger. If at all this is possible, all triggers can utilise it.

"Filter by Quick Search"
  // Prompt user for search query.
  $query = Input('Query Current List',,'Dimensions: > 1020 AND Dimensions: < 1980');

  // Search current list.
  $results = QuickSearch($query, '#', '|', 's');

  End $results == '', 'No results found.';

  // VF does not support paths so...
  // Reduce the results to just their names.
  $results = Report('|{Name}', $results);
  $results = SubStr($results, 1);  // Trim leading pipe.

  // Escape wildcards which might be in the names.
  $results = RegexReplace($results, '([?*#[])','[$1]');

  // Give the filter a nice caption.
  $results = """Quick Search Results: $query"" $results";

  // FILTER!!!!
  Filter $results;
