Question

I’m using IDE 10.5 Community edition.

In one project, I have multiple modules. I also have opened multiple tabs in the editor from different modules.

Is there a way to compare the content of two different tabs in the editor, which can be from different modules?

Answer 1

• Select two files (with pressed Ctrl) in project view panel → Right Mouse button → Compare Files.

• Right click on the file in project view → Compare With... (Ctrl+D)

• If you have opened one file in editor you can navigate in project view to another file and press right mouse button on that file Compare with Editor.

• It is possible to compare file against your clipboard content. View → Compare With clipboard

• Also you can use idea as external diff tool idea diff file1.txt file2.txt

Outdated; Old verison of IntelliJ: Also you can compare files from ‘Commander’ tab, just select two files in right and left panels, right click on any of them → Compare two files
