Support and Feedback / Re: ForEach Loop Not Working As Expected In V16

« Last post by Mathias (Author) on May 06, 2026, 07:28:49 »

Those new function are in BETA only.. so documentation can't be uptodate yet since it is not released yet-

You missed the parantheses

Code: [Select]

foreach( $rule in $rules)

Not

Code: [Select]

foreach $rule in $rules


MCScript has paratheses around all experssions for / if / for / while

Support and Feedback / ForEach Loop Not Working As Expected In V16

« Last post by total_annihilation00 on May 06, 2026, 07:12:36 »

it mentions ForEach has been added to MC but the ChatGPT AI scripts which incorporated ForEach Loops (for my "Smart Open (Ctrl+F9)" script all failed —worked when I used plain For Loop: Changelog states: "arrays and collections. (e.g. foreach $item in $array { ... }) MultiScript "

Here's my full script that was reduced to just 55 lines of MultiScript code from 443 initially then 140 /w Boolean OR's but now it's optimized greatly & highly scalable. But this is broken because ForEach Loop is not working properly:

Code: [Select]

@var $path = GetSourceFocusPath();
@var $ext = StrToLower( PathGetFileExtPart( $path, 2 ) );

@var $rules[] = {'udc|txt,ini,log,ahk,mtxt,vbs,conf,cpp,h,rc,asm,nfo,info,ps1,xml,jsee,cfg|b85b4bf468ab418e87b4e09e95dca4a0','udc|jpg,jpeg,jpe,jfif,png,gif,webp,bmp,tiff,psd,svg|c3424b15b3dd4a75a83ce0d9ba857bbb','udc|pdf,epub,djvu,mobi,fb2,cb7,cbr,cbt,cbz,prc,azw|3bd046dd55484d62aa82285076ea1c15','udc|zip|e271faf8469f4e96ac335fde319ab818','udc|chm|45cd3dfb7fc348ec99de80122481c55d','udc|sms,gen,smd,bin,md|468167006ee54bb995e28940823ec958','udc|sfc,smc,fig|6d1061dff5014030bcd2062fee6701cf','udc|nes|3d966becbbb640f983aab1f18a109f51','udc|wav,mp3,mid,midi,wma,flac,ogg,aac,alac,aiff|4e1f3a7ca0224c6ba0ff02f3f07cd7c4','udc|cur,ani|3c16c3020c384373a4dd96060cb856e3','run|pptx|\"C:\\Program Files\\Microsoft Office\\root\\Office16\\POWERPNT.EXE\"|/S \"{$path}\"','run|ppt|\"C:\\Program Files\\Microsoft Office\\root\\Office16\\POWERPNT.EXE\"|\"{$path}\"','run|sln|\"D:\\Download\\VS 19 CE\\Common7\\IDE\\devenv.exe\"|\"{$path}\"','udc|exe|e07317b5406b4c19b069ea4bd926f706'};

@var $matched = 0;

foreach $rule in $rules
{
    @var $parts = StrTokenize2Array( $rule, "|" );
    @var $kind = $parts[0];
    @var $extList = StrTokenize2Array( $parts[1], "," );

    if( arrayIFind( $extList, $ext ) > -1 )
    {
        $matched = 1;

        if( $kind == "udc" )
        {
            MC.RunUserCmd ID=$parts[2];
        }
        else if( $kind == "run" )
        {
            MC.Run CMD=$parts[2] ARG=$parts[3];
        }

        break;
    }
}

if( $matched == 0 )
{
    MessageBox( "SmartOpen", "No handler defined for extension: ." + $ext, 0 );
}

I get the following errors:
2026-05-06 10:33:33.325 Script engine error => Internal Script Function - Parse Error : "in"
2026-05-06 10:33:33.325 Script engine error - Line : 22, Error : -1 => Code : "foreach $rule in $rules"

When I resorted to this For Loop version /w Arrays, it worked perfectly w/o any errors:

        break;

}

if( $matched == 0 )
{
    MessageBox( "SmartOpen", "No handler defined for extension: ." + $ext, 0 );
}

Also the documentation needs to be updated so the AI can glean the syntax from the website. This is what I assume was added:
MultiScript supports the ternary operator (e.g. $a = $b ? $c : $d) MultiScript supports a "foreach" loop for iterating through

arrays and collections. (e.g. foreach $item in $array { ... }) MultiScript
supports new functions: Pow, abs, clamp, IsNumeric, StrStartsWith, StrEndsWith,
StrContains, StrFormat, StrPadLeft, StrPadRight, StrCount, StrRepeat,
ArrayReverse, ArraySlice MultiScript supports boolean operators AND / OR / NOT.

Still getting Bad Gateway when trying to upload, 7z is <67mb

Strange.. Works for me.. Tested on two different networks.. Maybe some FW that bocks for you ?

Thanks for the new build Mathias.  Lots of interesting additions to play with

I may .....so SFC /SCANNOW - also OK.

So adding items to an already running queue while also doing CRC checking ? Only if you do CRC at the same time ?

and yes current file copy will pause for a short while while it scan the new items that is added to the queue., but then it starts again.

If MC hangs, Not repsonding.. please go into task manager and select MultiCommander.exe process and right click and do Create Memory Dump file. then compress it and upload it at
http://multicommander.com/support/upload

Thanks for the reply Mathias.

• Yes queue is running & I am adding to it as it progresses (I normally do this as the move button allows me to add from different dirs easily, for years this method has been fine for me);
• I added CRC separately after first occurence - check done before & then after all moves completed, if MC has halted with High CPU use, I terminate it & then run CRC check on what has been copied.  So far, files that have actually moved pass CRC but anything else doesn't appear to arrive at all;
• The pause for additional files - previously not very noticeable even with big files, now as you can see from the screenshot the To: has a blank path suddenly, so something is being lost.

Since my update it's only happened ~5 times & I am trying to determine if I can replicate it effectively.  So far it's random but TM 'terminate' solves the problem, MC is restarted (Admin) & then works OK with identical files/dirs.

Trying to upload the dump gives "Bad Gateway  The proxy server received an invalid response from an upstream server."  will try again later...

Im not able to reproduce any issue

If To: is empty. then it got pasued in between two file operations.. before it started a new one. instead of in the middle of one.

  Thanks to the Boolean Operators —my script got optimized by "Grok-AI 4.20 Reasoning" to less than a quarter of its original size ! 'Smart Open (Ctrl+F9)' MultiScript went from 443 to just 103 lines of code (not discounting half of them being comments !), it's much more efficient & easier to maintain now ! I'am sure that /w Arrays & ForEach Loops it can be optimized even further.

Support and Feedback / Re: “Rename” option missing for some folders

« Last post by dddima on May 02, 2026, 22:51:40 »

Thank you for your replies.

I found the cause of the problem: some folders had the **Read-only** attribute set, and because of that the **Rename** option did not appear.

After I reset/removed the attributes, the **Rename** option appeared again and now works correctly.

Support and Feedback / Re: Right-click Menu not Fully Displaying

« Last post by Mathias (Author) on May 02, 2026, 10:12:37 »

How items are places in the Shell menu.. you have to take that with Microsoft.
Only customization MC do is to insert the "MultiCommander" submenu at the top, the rest of the items are added by Windows Explorer Shell system

Microsoft do lots of thing that is not fully supported when calling the offical API..  The only think MC can do it to send to shell menu system the flag CMF_CANRENAME  that say that the calling application (MC) supports rename so add that to the menu if you fell that it should be there
