Open Focused Item with PFA

[n2k]

Originated from this post: http://www.xyplorer.com/xyfc/viewtopic.php?f=3&t=11373
Again thanks to TheQwerty for giving me a head start with this

The script below is what I came up with and fully satisfies my needs as that it doesn't override the default behavior of Enter / Double-Click
This can be bound to a shortcut and is intended to expand on the Open Focused Item shortcut Ctrl+Enter

It has the following features:

• reads PFA list from ini file
  • so remember to save settings after making changes to your PFA list
• designed to support the following syntax: |"caption|path/to/icon" ext1;ext2>path/to/program
  • for this script to use a PFA it is required to begin each PFA entry with a | (pipe) and it should be enabled (ticked) in the list.
  • The caption is optional, the path/to/icon is optional, the path/to/executable doesn't need to be quoted

How to use this script:

1. Press SELECT ALL on the code block below
2. Press Ctrl+C to copy it to clipboard
3. In XYplorer go to User -> Manage Commands...
4. Select the the Run Script Category on the left side
5. Click the New button on the right side
6. Enter Open Focused Item with PFA as Caption
7. Click the Edit button right next to the Script: field
8. Press Ctrl+V in the Edit Script window
9. Click the OK button
10. Click the Assign Keyboard Shortcut... button
11. Press Ctrl+Enter (or whatever shortcut you want)
12. Click the OK button of the Free Keyboard Shortcuts window
13. Click the OK button of the Manage User-Defined Commands window
14. Done

Code: Select all

"Open Focused Item with PFA"
  // designed to support the basic ext format from PFAs: ext;ext>path/to/executable
  // could possibly support more, or might break, if you could test it and report back that'd be great :)
  
  $PFACount = getkey("Count", "FileAssoc");
  // might improve performance when just reading file once instead of doing it for every single PFA
  $PFAMatch = "";
  while ($PFACount > 0) {
    $PFA = getkey($PFACount, "FileAssoc");
    // if the PFA is activated (has +) and not already overriding the default application (has |)
    // the compare function returns 0 if the strings are equal
    if (!compare(substr($PFA, 0, 2), "+|")) {
      if(gettokenindex('"', gettoken($PFA, 1, ">", "t"), ">")) {
        $PFAnoCaption = gettoken($PFA, 3, '"', t, 2);
      }
      else {
        $PFAnoCaption = substr(gettoken($PFA, 1, ">", t, 2), 2);
      }
      // If the focused item's extension is in the list
      $PFAexts = gettoken($PFAnoCaption, 1, ">", "t");
      if (gettokenindex(<curext>, $PFAexts, ";")) {
        $PFAMatch = $PFA;
        break;
      }
    }
    $PFACount--;
  }
  
  if ($PFAMatch) {
    openwith gettoken($PFAnoCaption, 2, ">", "t"), "s", <curitem>;
  }
  else {
    #162; // File | Open Focused Item
  }
