Can I squash commits in Mercurial?

Question

I have a pair of commits that should really be just one. If I was using git, I would use:

git rebase -i 

and then

Answer 1

Let's assume you want to squash (unite) 2 most recent commits.

1. Find a revision number

   hg log -G -l 3
   

   possible output:

   @  changeset:   156:a922d923cf6f
   |  branch:      default
   |  tag:         tip
   |  user:        naXa!
   |  date:        Thu Dec 13 15:45:58 2018 +0300
   |  summary:     commit message 3
   |
   o  changeset:   155:5feb73422486
   |  branch:      default
   |  user:        naXa!
   |  date:        Thu Dec 13 15:22:15 2018 +0300
   |  summary:     commit message 2
   |
   o  changeset:   154:2e490482bd75
   |  branch:      default
   ~  user:        naXa!
      date:        Thu Dec 13 03:28:27 2018 +0300
      summary:     commit message 1
   

2. Soft reset branch

   hg strip --keep -r 155
   

3. Commit changes again

   hg commit -m "new commit message"
   

Notes

strip requires a built-in extension to be enabled. Create/edit ~/.hgrc config file with the following content:

[extensions]
strip =
