Gitk: Setting "Ignore space change" option to be true by default

Question

Is this possible in any way? I have tried git config --global alias.diff 'diff -b -w' but unfortunately that was not the solution.

Answer 1

It's a bit old but I found that question the other day googling, and the already accepted answer gave me a hint of how to do it.

No need to modify gitk itself: just edit your .gitk file (~/.config/git/gitk or ~/.gitk) and add:

set ignorespace 1

Answer 2

All that is really required here is to persist the value of the variable set by the checkbutton on the UI. The following patch achieves this. Or you could just force the default to be true at line 11475 (set ignorespace 1).

Note: Now (after Sept 2014) update gitk config_variables and add ignorespace

https://github.com/git/git/commit/9fabefb1f3f658e77eb18afa3f95efe1a0ee8d0d

All these are flushed to .gitk file.
