Compare/Replace selection or editor with clipboard #1862

SougandhS · 2025-05-08T01:25:22Z

This feature will allow users to compare either the selected text or the entire editor content against the current clipboard contents similar to other IDEs.

If users want to just compare just a selection in an editor, select the section and choose Compare with-> Clipboard
(I had changes copied..)

Selection.mp4

Selection2.mp4

If User want to compare entire Editor, either select all or select None and choose _Compare with-> Clipboard_

Entire.mp4

Hi @iloveeclipse
Could you please check this when you have some time ?

iloveeclipse · 2025-05-08T04:26:45Z

I'm biased here, since this feature is provided by AnyEdit Tools plugin since years:
https://marketplace.eclipse.org/content/anyedit-tools

SougandhS · 2025-05-08T04:34:15Z

I'm biased here, since this feature is provided by AnyEdit Tools plugin since years: https://marketplace.eclipse.org/content/anyedit-tools

but having it built directly into Eclipse makes it easier and more consistent for users—no need to install or manage extra plugins just to do something that feels like it should be built-in

vogella · 2025-05-12T11:12:52Z

In my testing this does not reliable work.

For example in copy f.application from this file:

Now I select a java file and select Compare With -> Clipboard nothing happens.

iloveeclipse · 2025-05-12T11:15:11Z

Why not let this feature be in AnyEdit plugin? It's tested, has more features etc.

vogella · 2025-05-12T11:23:14Z

Why not let this feature be in AnyEdit plugin? It's tested, has more features etc.

Having it in standard is desired for such a useful and core feature. Also I don't think every user has AnyEdit installed, for example I think I never did install it.

iloveeclipse · 2025-05-12T11:32:26Z

I would expect then that this contribution would add same functionality AnyEdit provides for clipboard, means also context menus for files in Package Explorer, not just "Compare with..." but also "Replace with.." etc.

Sure. i'll add Replace with clipboard feature too 👍

Thanks. Next issue I see, is that it seems that I can also do this compare once. I tested my scenario above. After that I copied some source code from the compare editor and did the compare on another file. Nothing happens.

This is fixed now + Added replace with clipboard functionality + Compare/Replace from Project/Package exp context menu

Replace_1.mp4

Replace_2.mp4

Reproduced and handled this now

vogella · 2025-05-16T06:41:38Z

Testing this again.

I don't think compare is correct for this example:

Create a text file, in my example lars.adoc with the following content:

lars
testing
compare
asdfklklsdf

Copy the last two lines into the clipbard.
Select the file and select compare with clipboard
Result:

@SougandhS please have a look

SougandhS · 2025-05-16T07:09:46Z

@SougandhS please have a look

Thanks for this case. Its fixed now

Hi @vogella , could you please review this when you have time?

LGTM, thanks @SougandhS

vogella · 2025-07-02T12:12:52Z

@SougandhS can you please add this to the N&N for the next release? I think this would be the place: https://github.com/eclipse-platform/www.eclipse.org-eclipse/blob/master/news/4.37/platform.md

iloveeclipse · 2025-07-02T14:40:05Z

There is a problem (at least for me it is one) with the compare editor, which will be visible if you compare what AnyEdit provides with the current implementation. Please make sure the compare allows to modify the text file, currently it only allows read-only mode.
