The merge buttons have a bug
ExternalCompare Product WinMerge Merge
Should be
ExternalCompare Product WinMerge Command Merge
As for WinmergeV2, if the command line args are the same it should work. If the command line arguments have changed check the Configuration of a new tool details in the first post.
@wowbagger receive the following when selecting EllieComputing:
Attempted holding shift and clicking button again, but same result.
Please advise.
Thanks!
the menu needs updating. Its missing the word Command, on the second line of the button. Also there is a bug where it's not showing the name of the exe correctly. Will update when at home.
If you update your button it should work.
From this
@icon:#ExternalCompare:EllieComputing,$glob:ExternalCompareMerge+EllieComputing
ExternalCompare Product EllieComputing Merge
Should be this
@icon:#ExternalCompare:EllieComputing,$glob:ExternalCompareMerge+EllieComputing
ExternalCompare Product EllieComputing Command Merge
Works, thanks!
I'm trying to install this, and I cannot get the button to show any icons. What am I doing wrong?
I've installed the script and it is enabled. I have then dragged the ExternalCompare.dcf file onto my toolbar after entering Customize Toolbar mode…
But I still get this:
I don't get it?
You can edit the individual buttons in the menu via Settings > Customize. They will be pointing to icons in exe files which aren't in the same place (or aren't anywhere, potentially) on your system.
Ahhh okay, thanks! Sorry, I thought that the icons were all supposed to be there, but greyed out if the paths weren't configured (as per this post External Compare and Merge Tools 2.0).
As always, well impressed with the speed with which you give help here Leo!
The icons are included in the ExternalCompare.osp, which also includes the script.
Assuming that package is installed and enabled then they should appear.
I've taken the liberty of modifying the icons provided to better display with a dark theme. Some icons I left untouched, but tried to ensure every program had at least one good alternate.

This confused me a little, so I hope it helps someone in future.
The included toolbar has a small bug: The command for all right click buttons (when it supports merge) is:
ExternalCompare Product PRODUCT_NAME Merge
When it actually should be:
ExternalCompare Product PRODUCT_NAME Command Merge
I hope it helps 
working a treat for me with WinMerge. much appreciated.
In DOpus13, an issue when using global var.
@icon:#ExternalCompare:BeyondCompare3,$glob:ExternalCompare+BeyondCompare4
the code above will report an error.
so I modified like this:
for script:
matchedCommand.resourceKey = (typeof(matchedCommand.Executable) == "undefined") ? "ExternalCompare_"+matchedCommand.product : "ExternalCompare_"+matchedCommand.product+"_"+matchedCommand.commandName;
for button:
@icon:#ExternalCompare:BeyondCompare3,$glob:ExternalCompare_BeyondCompare4
change "+" to "_"
how did you find this ??? I had the following error but I didn't even know where to look.
I checked the script, but didn't think of checking the button.
02/02/2024 11:10 Evaluator: Error at line 1, position 31
Unknown value (6): WinMerge
!!($glob:ExternalCompareMerge+WinMerge)
And why does it fix the issue ? (replacing + by _ )
In the button，the first line ，@icon command use $glob:var.
not in the script.
$glob:ExternalCompareMerge+WinMerge
the string "WinMerge" after "+" will be treated as a variable. this is an issue in DO13, not DO12
I had the same issue after upgrading to v13, I meant: what information guided you to the button code ?
There was no indication on my side, only "Evaluator: Error at line 1, position 31" which didn't help me to locate the code.
And also, I was wondering why replacing "+" by "_" would fix the issue ? What is the reason behind this fix ?
thank you 
I test many times, and finally found "line 1" is in the button.
A fix for that will be in 13.5.1 (after 13.5 goes out).
this is a great tool. i came to the forum looking for way to have my Beyond Compare 5 button see both listers at once and found sooo much more as usual! 
ill just chime in with....
im using Beyond Compare 5Beta.
at first i tried to update the buttons to reflect the version by changing BeyondCompare4 to -> BeyondCompare5 .
the script did not like that and gave me this error.
i peeked at the script to see i could change it myself but that code way over my head.
so i just changed the 5 back to 4 inside the button, selected the .exe for V5.b and it works just fine.
Thanks for this!
ps... Beyond Compare 5 is a great step up! even in beta. beside dark mode they've added\merged their media comparisons softwares into this one tool.
try Leo's fork
is there .pdf compare as images?
@fkast im not sure about its .pdf capabilities. its a format i despise and try to avoid. let me see what i can dig up...
haha, here a fun example...
the files are...
the text content are the "Same" as BC5 is saying, visually they are in light and dark mode.
one side is a lighter shade of grey, other wise im not seeing any visual diffrences. nor any options in the menus.
not to say such an option is not there. it might be, ive only been using this software for month so im not fully sure of what all it can handle. it can compare images, not sure if theres a way to toggle "pdf as images"
i was using winmege before on simple text docs.
