Support unified format like kubectl diff for difftool compatibility (Meld)

[Llyth]

Hello,

kubectl diff by default output in an unified format like diffutils does. It also supports KUBECTL_EXTERNAL_DIFF environment variable which can be used to pass a gui tool like Meld.

Is it possible to add an unified format option to --output ?

• https://www.gnu.org/software/diffutils/manual/diffutils.html#Unified-Format
• https://meldmerge.org/

Best regards.

I am also interested, recently argocd also included it.

The helm diff format is already unified, what kind of output are you referring to?

Currently kubectl/argocd support using any external tool like diff, vs code, sublime, etc. to show the diff which is especially useful when diff are exceptionally long.
