Here’s a few git settings that I prefer to set, now that I actually work on projects with other people and care for a useful history.
git config --global branch.master.mergeoptions "--squash"
This always squashes merges into master. I think that work big enough to require multiple commits should be done in a branch, then squash-merged into master. That way, master becomes a great overview of individual features rather than the nitty-gritty of all the back and forth of a feature.
git config --global pull.rebase true
This always rebases your local commits, or, in plain english: It always puts your local, unpushed commits to the top of the history when you pull changes from the server. I find this useful because if I’m working on something for a while, I can regularly pull in other people’s changes without fracturing my history. Yes, this is history-rewriting, but I care more for a useful rather than a “pure” history.
Combined with git repository hosting (GitLab, GitHub Enterprise, etc.), I found that browsing history is a really useful tool to keep up code changes (especially across timezones), provided that the history is actually useful.
