This way, the username is not leaked. Also, it makes it easy to visually spot when a path is in the user’s home directory.

i really like that. recently was thinking about doing a UI.input before copy&paste - and asking the user for strings that they wan't to be removed? like (app identifier ...) - what do you think about it @0xced

[0xced]

@hjanuschka This is a good idea, but it should be done in another pull request IMHO. I wonder how much data we could anonymize automatically, without needing UI.input.

In the super edgy edge case that the user's home dir is the prefix of other folders this is gonna output garbage. Example: $HOME=/work, anonymized_path("/workspace/whatever/fastlane") => ~space/whatever/fastlane.

Might be more applicable to linux where the user's home dir is not generally inside the /Users/ folder.

@milch @0xced

how about this PR here -> #5982
we could refactor all options and set the flags on all critical parameters, and use this in some way to anonymize?

[milch]

@hjanuschka Yeah, I've thought about something like that before. Sounds good to me, @0xced do you have any thoughts about that?

[0xced]

I updated the code, and added a spec.

With $HOME == /Users/john
/Users/john/.fastlane/bin/bundle/bin/fastlane → ~/.fastlane/bin/bundle/bin/fastlane
/Users/john → ~
/Users/john/ → ~/

With $HOME == /work
/workspace/project/test → /workspace/project/test

Looks good now! Thanks for your contribution 🚀
