Github PR 时合并多次提交的 git commits All In One

git commit -s

GitHub 会帮你把新增的 commits 全部追加到一个未合并 PR 里去（PR 会自动更新）

git add <files>
git commit -s -m "some description here"
# s, squash <commit> = use commit, but meld into previous commit
 -s === --squash

git push origin feat-xxx

PR 前合并多个 Commits，方便 code review ✅

# 通过 rebase 命令来完成 2个/多个 commits 的合并
$ git rebase -i HEAD~2 
# $ git rebase -i HEAD~n 

# vim 编辑，把最后面的一条/多条 commit 的 `pick`  改成 `s` 
`pick` 9b7d63b docs: just for test => `s` 9b7d63b docs: just for test

#
# Commands:
# p, pick = use commit
# r, reword = use commit, but edit the commit message
# e, edit = use commit, but stop for amending

# s, squash = use commit, but meld into previous commit 
# s: 使用该 commit, 但是要把它合并到前面一条 commit 中去 ✅

# f, fixup = like "squash", but discard this commit's log message
# x, exec = run command (the rest of the line) using shell
# d, drop = remove commit
#
# These lines can be re-ordered; they are executed from top to bottom.
#
# If you remove a line here THAT COMMIT WILL BE LOST.
#
# However, if you remove everything, the rebase will be aborted.

在本地确认 commits 已经完成合并，这时候就可以继续推送到远程，让 PR 也更新掉

$ git push -f origin feat-xxx

这里需要有一个-f参数来强制更新，合并了 commits 本质也是一种冲突，需要冲掉远程旧的 commits 记录。

demos

5 commits => 1 commit ✅

$ git rebase -i HEAD~5

# vim edit 第一次，修改 `pick` => `s`
# vim edit 第二次, 编辑 commit message ✅

$ git push

??? shit 截图丢失了 WTF 💩

查看云端历史版本, 找回 ??? 并没有 ❌

GitHub 上找回来了 🎉

https://github.com/xgqfrms-GitHub/git-combine-history-commits/pull/2

# vi / vim 进入 edit
$ git rebase -i HEAD~5

# vi / vim 退出 edit
ESC
:wq
# 或
:wq!

# Rebase e33798b..466c20a onto e33798b (5 commands)
#
# Commands:
# p, pick <commit> = use commit
# r, reword <commit> = use commit, but edit the commit message
# e, edit <commit> = use commit, but stop for amending
# s, squash <commit> = use commit, but meld into previous commit
# f, fixup [-C | -c] <commit> = like "squash" but keep only the previous
#                    commit's log message, unless -C is used, in which case
#                    keep only this commit's message; -c is same as -C but
#                    opens the editor
# x, exec <command> = run command (the rest of the line) using shell
# b, break = stop here (continue rebase later with 'git rebase --continue')
# d, drop <commit> = remove commit
# l, label <label> = label current HEAD with a name
# t, reset <label> = reset HEAD to a label
# m, merge [-C <commit> | -c <commit>] <label> [# <oneline>]
# .       create a merge commit using the original merge commit's
# .       message (or the oneline, if no original merge commit was
# .       specified); use -c <commit> to reword the commit message
#
# These lines can be re-ordered; they are executed from top to bottom.

合并多个历史 commits, 用于 PR，减少 code review 成本 ✅

delete #3 #5 commit

# $ git push -f origin feat-xxx

$ git push -f

这里需要有一个-f参数来强制更新，合并了 commits 本质也是一种冲突，需要冲掉远程旧的 commits 记录。

修改过去的提交记录

amend 修正

# 如果指定提交之后再次指定提交，就会显示提交清单。
# 请在清单里找出要修改的提交，将该行的 “pick” 改成 “edit”，之后保存并退出。
$ git rebase -i <commit>

# 接着，编辑要修改的文件，保存文件之后指定--amend选项，以执行提交。
$ git commit --amend

# 最后，指定--continue选项以执行rebase。
$ git rebase --continue
