Found this command line:
on MacOSX: (IDEA EAP 11)
/Applications/IntelliJ\ IDEA\ 11.app/Contents/MacOS/idea diff /Users/ben75/file1.txt /Users/ben75/file2.txt
On MacOSX it can’t run when IDEA (11) is open.
on Windows: (IDEA EAP 12)
"C:\Program Files (x86)\JetBrains\IntelliJ IDEA 12.0\bin\idea.exe" diff C:\Users\ben75\file1.txt C:\Users\ben75\file2.txt
It runs even if IDEA is already open.
I have trouble when trying to compare files with no extensions (or extensions that don’t match )
Directly from IDEA (EAP 12)
Not so easy, but it works…
- File > Open… > select “file1.txt”
- File > Open… > select “file2.txt”
- Create a “Favorite list” and add both files to this favorite list.
(to do this : ctrl+right-click on file name tab in the editor > add
to favorite > select the favorite list just created – see screenshot) - Finally, open the “Favorites” view (Alt+2 or click on it on the left or your IDEA windows).
- Select both files
- Right click : “compare two files” (or ctrl+D)
