问题
While working on a branch that I've opened a pull request on, I would like to see the exact same diff that GitHub displays on the commandline. What is the particular git diff command that replicates the list of changes GitHub displays for a pull request?
回答1:
If you don't want to do any git fetch and update a local PR branch, you simply can use cli/cli, the command-line interface for GitHub.
The release 0.9.0 includes gh pr diff
回答2:
The closest thing is to diff with the common ancestor between your feature-branch and your base-branch.
Something like:
git diff `git merge-base feature-branch base-branch`

Not sure if there is a way to get the actual diff format closer to Github style but $ git diff master...<branch_name> seems to show the set of changes that a pull request would show (assuming it's a pull request against master). The list of changed files in a pull request seems to be equivalent to $ git diff --name-status master...<branch_name>. I guess this all assumes that your local branches are up-to-date with the remote Github branches
回答4:
See the Reviewing and Synchronising section in GitHub advanced training. In particular, after fetching the pull request you can view the diff prior to merging:
$ git fetch origin refs/pull/1/head
$ git show FETCH_HEAD
回答5:
git diff branchA branchB should work, no?
More info on other perhaps useful diff notations can be found here
