I've been using Meld to compare directories recursively. I want to know how to export the comparison result onto a new file. Meld is a visual tool but is there any way I can save the comparison?
As of version 3.18.0 this is not a supported feature.
You can see the advertised features here.
If you dig into the code, an UI option to save content (and subsequent implementation) is only present in data/ui/filediff.ui and not in data/ui/dirdiff.ui. This means comparison output can only be exported when comparing files.
The code snapshot is from the latest commit on master, January 2 2018: 945014f5.
