Folllow thia step,To How to compare two files that have only numbers?

Step 1 :- Install Compare plugin

Step 1 :-Open Notepad++ and Click on the ‘Plugins’ then ‘Plugins Admin’
Step 2 :-A list of available plugins will appear
Step 3 :-TIP: if the list is empty you need to check your Internet connection or 
             proxy settings.
Step 4:-  Either search or scroll until you see ‘Compare’
Step 5:- Place a tick next to the name then click on the ‘Install’ button

   Step 2 :- Click on the ‘Plugins’ menu then ‘Compare’ and ‘Compare’ again
   Step 3 :- The files will be displayed, side by side, with the differences 
                highlighted

   Step 4 :- It helps to keep the ‘old’ copy of your file on the left and the ‘new’ on the right – this should help with understanding how the plugin shows the difference between files.

I hope this information will be usefull.
Thank you.

Edit: I had to start notepad++ with administrator mode. It is all good now! Thanks for your help! And @pnedev thanks for the great plugin!

I’ve been using the last Notepad++ release v7.8.5, for about a month now, with ComparePlus.dll, build 488, without any trouble

Let me guess, x86 version? Just don’t use x64 one, problems are more likely to be visible there.

I downloaded the penultimate version Build 506, from @AlexVerschoot, … … and I suppose you guess why I specifically chose that build, ah ah !

Ha-ha-ha, I suspected you would do that ;))

Nevertheless, I like your idea of Advanced Ignore dialog, too …

Thank you!

Thanks for your warning and your kind words ! However, I’ve been using the last Notepad++ release v7.8.5, for about a month now, with ComparePlus.dll, build 488, without any trouble ;-))

When elaborating my reply to @FQVBSina, I downloaded the penultimate version Build 506, from @AlexVerschoot, … … and I suppose you guess why I specifically chose that build, ah ah ! I ran tests with various regexes, + N++ v7.8.5, and it worked great, without any weird issue !

Nevertheless, I like your idea of Advanced Ignore dialog, too ;-))

I wish you a good end of development of your new ComparePlus plugin !

Cheers,

Just one remark:
If you are using ComparePlus dev version make sure your Notepad++ version is < 7.7 because the new Scintilla API changes after N++ 7.7 are not yet incorporated into CP and that might cause weird issues.

@guy038 ,
Thank you for the excellent description :)

In other words, I suppose that you would like something like the feature described in that post :

https://community.notepad-plus-plus.org/topic/17546/compare-plugin-unable-to-turn-off-synchronize-vertical-scrolling-version-7-6-6-with-compare-v2/31

If so, you could download a pre-release of the New ComparePlugin library of @Pnedev, which is, now, called ComparePlus

Then, just follow the instructions of that post , below , in order to download the last ComparePlus.dll library :

https://community.notepad-plus-plus.org/topic/17546/compare-plugin-unable-to-turn-off-synchronize-vertical-scrolling-version-7-6-6-with-compare-v2/36

Notes :

• Beware that the last build changed and is, now, the Build 507 and that is a pre-release of the future ComparePlus v1.0

• Respect the organization of all files and folders, related to ComparePlus, as described in the tree

• Preferably, delete your present Compare.ini file, in the Config folder

• Restart N++ and enjoy the new ComparePlus plugin !

• For your specific task, simply, check the option Detect Diffs on Character Level, in the menu Plugin > ComparePlus
